Abstract
Description
Technical Field
[0001] The present invention relates to a hard butter composition. The present invention further relates to an oily confectionery containing the hard butter composition, a food product comprising a thin film formed of the oily confectionery, and a method for suppressing cracking of chocolates using the hard butter composition.
Background Art
[0002] Conventionally, composite chocolate foods produced by combining chocolate with other food materials have been commercially available, such as foods obtained by coating confectionery and bread with chocolate, and chocolate confectionery containing fruits, nuts, alcoholic beverages and the like inside. For thin-film chocolates such as the aforementioned coating chocolate and shell chocolate, cracking may occur due to the influence of moisture derived from the food material to be combined, or external stress such as vibration during transportation. When cracking occurs, the appearance of the food is impaired, and the quality of the food material to be combined changes, which reduces the commercial value of the product.
[0003] As technologies contributing to suppressing cracking of chocolate, for example: a method for producing chocolate characterized by using an oil / fat that contains a specific amount of disaturated monounsaturated glyceride and contains a specific amount of disaturated monolinoleate in the disaturated monounsaturated glyceride (Patent Document 1); an oil / fat composition for coating characterized by containing a specific amount of randomly transesterified oil / fat and having a solid fat content (SFC) within a specific range at each temperature of 10°C, 20°C, 30°C and 40°C (Patent Document 2); a chocolate containing a combination of specific amounts of lauric oil / fat and non-lauric oil / fat (Patent Document 3); and a coating chocolate containing glycerin oleate and / or diglycerin oleate (Patent Document 4) have been proposed.

[0010] According to the present invention, there can be provided a hard butter composition that suppresses the occurrence of cracking in thin-film chocolate, particularly in temper-type chocolate.
Mode for Carrying Out the Invention
[0011] Preferred embodiments of the present invention are described below. The present invention is not limited by the following description, and each constituent element can be appropriately altered without departing from the gist of the present invention.
[0012] [Hard Butter Composition] The hard butter composition of the present invention is characterized by comprising the following oil or fat (A). Oil or fat (A): an oil or fat wherein the content of S3 triglycerides with CN of 44 or more is 2 to 50% by mass, and the content of monoacid S3 triglycerides with CN of 44 or more is 1.9% by mass or more provided that CN represents the total number of carbon atoms of constituent fatty acid residues of the triglyceride, S represents a saturated fatty acid residue, S3 triglyceride refers to trisaturated triglyceride.
[0013] In this invention, the term "monoacid type" for S3 triglycerides refers to the fact that the three saturated fatty acid residues S that constitute the S3 triglyceride are identical.
[0014] In the fat (A), the content of S3 triglycerides of CN44 or higher is 2% by mass or more, preferably 2.2% by mass or more, more preferably 2.4% by mass or more, 2.5% by mass or more, 2.6% by mass or more, 2.8% by mass or more, or 3% by mass or more, and even more preferably 3.2% by mass or more, 3.4% by mass or more, or 3.5% by mass or more, from the viewpoint of suppressing cracking. The upper limit of the content of the S3 triglycerides is 50% by mass or less, preferably 49% by mass or less, more preferably 48% by mass or less, and even more preferably 47% by mass or less, from the viewpoint of suppressing cracking.
[0015] S3 triglycerides with CN44 or higher are not particularly limited as long as the total number of carbon atoms of the three saturated fatty acid residues S constituting the triglyceride is 44 or more. Preferably, the content of S3 triglycerides with CN44 to 60 is within the above range.
[0016] In the oil (A), the content of monoacid-type S3 triglycerides of CN44 or higher is 1.9% by mass or more, preferably 2% by mass or more, more preferably 2.2% by mass or more, and even more preferably 2.4% by mass or more, from the viewpoint of suppressing cracking. The upper limit of the content of the monoacid-type S3 triglycerides is preferably 10% by mass or less, more preferably 8% by mass or less, and even more preferably 7% by mass or less or 6% by mass or less, from the viewpoint of suppressing cracking.
[0017] The monoacid type S3 triglycerides with CN44 or more are not particularly limited as long as the total number of carbon atoms of the three saturated fatty acid residues S constituting the triglyceride is 44 or less and the three saturated fatty acid residues are the same. Examples include P3 triglycerides (CN48), St3 triglycerides (CN54), and A3 triglycerides (CN60). Here, P represents a palmitic acid residue, St represents a stearic acid residue, and A represents an arachidic acid residue (the same applies hereafter).
[0018] In the present invention, the analysis of constituent triglycerides in oils and fats can be performed by high-performance liquid chromatography (HPLC) in accordance with the "Standard Test Methods for Analysis of Oils and Fats 2.4.6.2-2013" established by the Japan Oil Chemists' Society. The triglyceride composition shown in the present invention is based on values measured by high-performance liquid chromatography (HPLC) in accordance with the "Standard Test Methods for Analysis of Oils and Fats 2.4.6.2-2013" established by the Japan Oil Chemists' Society, and the same applies hereinafter.
[0019] From the viewpoint of further suppressing the occurrence of cracks, the total content of asymmetric triglycerides selected from the group consisting of PPO triglycerides, PStO triglycerides, and StStO triglycerides in the oil (A) is preferably 4 to 40% by mass. Here, PPO triglyceride is a triglyceride in which the palmitic acid residue P is bound to the 1st and 2nd positions of glycerin, and the oleic acid residue O is bound to the 3rd position of glycerin. Similarly, PStO triglyceride is a triglyceride in which P and St are bound to the 1st and 2nd positions of glycerin, and the oleic acid residue is bound to the 3rd position of glycerin, and StStO triglyceride is a triglyceride in which the stearic acid residue St is bound to the 1st and 2nd positions of glycerin, and the oleic acid residue O is bound to the 3rd position of glycerin. The inventors have confirmed that, in combination with the aforementioned conditions relating to the content of S3 triglycerides of CN44 or higher and the content of monoacid-type S3 triglycerides, the occurrence of cracks can be further suppressed when the total content of the asymmetric triglycerides is within the above-mentioned preferred range.
[0020] The total content of the above-mentioned asymmetric triglycerides in the oil (A) is more preferably 4.2% by mass or more, 4.4% by mass or more, or 4.5% by mass or more. The upper limit of the total content of the asymmetric triglycerides is more preferably 38% by mass or less, 36% by mass or less, or 35% by mass or less.
[0021] Other conditions that oil (A) is preferably satisfied with are described below.
[0022] -Total content of triglycerides with CN44 or higher- The fat (A) used in the hard butter composition of the present invention preferably has a total content of triglycerides of CN44 or higher of 60% by mass or more. Here, the total content of triglycerides of CN44 or higher means the sum of the content of each triglyceride, namely S3 triglyceride, S2U triglyceride, SU2 triglyceride, and U3 triglyceride, of CN44 or higher. Here, U represents an unsaturated fatty acid residue, S2U triglyceride represents a disaturated monounsaturated triglyceride, SU2 triglyceride represents a monosaturated diunsaturated triglyceride, and U3 triglyceride represents a triunsaturated triglyceride (the same applies hereinafter). In fat (A), the upper limit of the total content of triglycerides of CN44 or higher is not particularly limited, but may be, for example, 99% by mass or less, 98% by mass or less, 97% by mass or less, 96% by mass or less, etc.
[0023] Triglycerides with CN44 or higher are not particularly limited as long as the total number of carbon atoms of the three fatty acid residues constituting the triglyceride is 44 or more. Preferably, the total content of triglycerides with CN44 to 60 is within the above range.
[0024] -Content of each triglyceride: S2U, SU2, and U3- In the oil (A), the content of S2U triglycerides with CN44 or higher is preferably 10% by mass or more, more preferably 12% by mass or more, or 14% by mass or more. The upper limit of the S2U triglyceride content is preferably 90% by mass or less, more preferably 88% by mass or less, 86% by mass or less, 85% by mass or less, 84% by mass or less, or 82% by mass or less. S2U triglycerides with CN44 or higher are not particularly limited as long as the total number of carbon atoms of the two saturated fatty acid residues S and one unsaturated fatty acid residue U constituting the triglyceride is 44 or more (the preferred range for the content of specific asymmetric type triglycerides among S2U triglycerides is as described above). Preferably, the content of S2U triglycerides with CN44 or higher and CN60 or lower is within the above range.
[0025] In the oil (A), the content of SU2 triglycerides with CN44 or more is preferably 0.5% by mass or more, more preferably 0.6% by mass or more, 0.8% by mass or more, or 1% by mass or more. The upper limit of the SU2 triglyceride content is preferably 25% by mass or less, more preferably 24% by mass or less, or 23% by mass or less. SU2 triglycerides with CN44 or more are not particularly limited as long as the total number of carbon atoms of the one saturated fatty acid residue S and two unsaturated fatty acid residues U constituting the triglyceride is 44 or more. Preferably, the content of SU2 triglycerides with CN44 to 60 is within the above range.
[0026] In the oil (A), the content of U3 triglycerides with CN44 or higher is preferably 4% by mass or less, more preferably 3.8% by mass or less, 3.6% by mass or less, 3.5% by mass or less, 3.4% by mass or less, or 3.2% by mass or less. When the content of U3 triglycerides with CN44 or higher is within the above range, it is preferable as it facilitates the creation of oil-based confectionery exhibiting good heat resistance. The lower limit of the content of the U3 triglycerides is not particularly limited and may be 0% by mass. U3 triglycerides with CN44 or higher are not particularly limited as long as the total number of carbon atoms of the three unsaturated fatty acid residues U constituting the triglyceride is 44 or more. Preferably, the content of U3 triglycerides with CN44 to 60 is within the above range.
[0027] -Solid fat content SFC- The ratio (SFC-25 / SFC-35) of the solid fat content SFC-25 (%) at 25°C to the solid fat content SFC-35 (%) at 35°C of the fat (A) is preferably 2 to 13. The inventors have confirmed that when the ratio SFC-25 / SFC-35 is within the above preferred range, in combination with the conditions relating to the S3 triglyceride content of CN44 or higher and the monoacid type S3 triglyceride content as described above, it is easier to realize oily confectionery that exhibits good melt-in-the-mouth properties while suppressing the occurrence of cracks. The ratio SFC-25 / SFC-35 is more preferably 2.2 or higher, 2.4 or higher, 2.5 or higher, 2.6 or higher, 2.8 or higher, or 3 or higher. The upper limit of the ratio SFC-25 / SFC-35 is more preferably 12 or lower, 11 or lower, 10.5 or lower, or 10 or lower. Furthermore, the solid fat content of SFC-35 at 35°C is preferably 3% or more, more preferably 4% or more or 5% or more, with an upper limit of preferably 40% or less, more preferably 38% or less.
[0028] The solid fat content SFC-20 of oil (A) at 20°C is preferably 45% or more, more preferably 50% or more, from the viewpoint of further suppressing cracking when combined with the conditions related to the S3 triglyceride content of CN44 or higher and the monoacid type S3 triglyceride content mentioned above. The upper limit of the solid fat content SFC-20 is not particularly limited, but can be, for example, 90% or less, 85% or less, or 80% or less.
[0029] The SFC value indicates the solid fat content in an oil at a predetermined temperature and can be measured by conventional methods. However, in this invention, the SFC of the sample to be measured is measured using pulsed NMR (direct method) as described in AOCS official method cd16b-93, and the value obtained by converting the measured value to the amount of oil phase is used. That is, when measuring a sample that does not contain an aqueous phase, the measured value becomes the SFC, and when measuring a sample that contains an aqueous phase, the value obtained by converting the measured value to the amount of oil phase becomes the SFC (the same applies to the measurement of SFC hereafter).
[0030] In the hard butter composition of the present invention, the content of fat (A) is not particularly limited as long as the effects of the present invention are achieved, but is preferably 80% by mass or more, more preferably 85% by mass or more, and even more preferably 90% by mass or more. The upper limit of the content of fat (A) is not particularly limited and may be 100% by mass. Other components that the hard butter composition of the present invention may contain (hereinafter also referred to as "auxiliary components") will be described later.

[0046] The oil and fat (A-1) is preferably obtained by fractionating palm-based random transesterified oil and fat. A preferred embodiment for producing the oil and fat (A-1) will be described below.
[0047] First, a fat and oil mixture is prepared in which the sum of the content of P and St in the constituent saturated fatty acid residues is 95% by mass or more. The fats and oils used to obtain such a fat and oil mixture are not particularly limited, and for example, one or more can be selected and mixed from various vegetable oils and animal fats such as soybean oil, rapeseed oil, corn oil, cottonseed oil, olive oil, peanut oil, rice oil, safflower oil, sunflower oil, palm oil, palm kernel oil, coconut oil, monkey fat, mango fat, milk fat, beef fat, lard, cocoa butter, fish oil, whale oil, etc., as well as fats and oils that have been subjected to one or more physical or chemical treatments such as hydrogenation, fractionation, and transesterification, to obtain the above fat and oil mixture.
[0048] The composition of constituent fatty acid residues can be measured by capillary gas chromatography, for example, by referring to "Standard Test Methods for Analysis of Fats and Oils 2.4.2.3-2013" and "AOCS Method Ce-1h05" established by the Japan Oil Chemists' Society.
[0049] In particular, it is preferable to include highly hydrogenated oils and fats in the oil and fat formulation from the viewpoint of increasing the content of St and P in the constituent fatty acid residues and making it easier to adjust conditions such as the content of S3 triglycerides of CN44 or higher and the content of monoacid-type S3 triglycerides to the above-mentioned preferred range.
[0050] Examples of highly hydrogenated oils include highly hydrogenated palm oil, highly hydrogenated soybean oil, highly hydrogenated rapeseed oil, and high-oleic sunflower oil.
[0051] When using highly hydrogenated oils and fats, it is preferable to use highly hydrogenated oils and fats with an iodine value of 3 or less, and more preferable to use highly hydrogenated oils and fats with an iodine value of 1 or less, from the viewpoint of substantially eliminating the presence of trans fatty acids.
[0052] When using highly hardened oil as one of the raw materials for oil and fat (A-1), any amount of oil and fat (A-1) may be used as long as it satisfies the aforementioned conditions such as the content of S3 triglycerides of CN44 or higher and the content of monoacid-type S3 triglycerides. However, the content of highly hardened oil in the oil and fat compound is preferably 32 to 52% by mass, more preferably 37 to 47% by mass.
[0053] Next, random transesterification is performed on the prepared oil and fat mixture. Random transesterification can be carried out by conventional methods, such as using a chemical catalyst such as sodium methoxide, or by using an enzyme such as lipase derived from the genera Alcaligenes, Rhizopus, Aspergillus, Mucor, Penicillium, etc. The lipase can be immobilized on a carrier such as an ion exchange resin, diatomaceous earth, or ceramic and used as an immobilized lipase, or it can be used in powder form.
[0054] Next, the randomly transesterified oil and fat mixture is separated by solvent fractionation or crystallization as detailed below. The resulting low-melting-point portion or medium-melting-point portion can then be preferably used as oil and fat (A-1).
[0055] Furthermore, the fractionation operation may be performed multiple times to obtain the fractional low-melting point portion or fractional medium-melting point portion of the randomly transesterified oil. In this case, solvent fractionation may be performed in two or three or more stages with different conditions, crystallization may be performed in two or three or more stages with different conditions, or solvent fractionation and crystallization may be combined.
[0056] The separation method can be selected arbitrarily, but if the mass ratio of St to P (St / P) in the constituent fatty acid residues of the separated oil is less than 0.4, solvent separation is preferred, and otherwise, separation by crystallization is preferred.
[0057] (Solvent separation) The solvent used for solvent fractionation is not particularly limited as long as it is a solvent that dissolves the transesterified oil to be fractionated. However, since the resulting fractionated oil will be used for food, it is preferable to select acetone or hexane.
[0058] The amount of solvent used is not particularly limited, but from the viewpoint of industrial productivity, it is preferable to add 50 parts by mass or more of solvent per 100 parts by mass of transesterified oil to be separated, more preferably 100 to 1000 parts by mass, and even more preferably 200 to 500 parts by mass.
[0059] When dissolving oils and fats in a solvent, it is necessary to first thoroughly dissolve the high-melting-point fraction that will be removed by fractionation, so it is preferable to heat the solvent to 30-70°C. The temperature at which the oils and fats dissolved in the solvent are cooled and held (cooling temperature) varies depending on the type of organic solvent, but it is preferable to use 0-30°C when using acetone and -10-20°C when using hexane. The time at which the mixture is held at the cooling temperature (cooling time) is preferably 0.1 hours to 100 hours, more preferably 0.5 hours to 50 hours, from the viewpoint of sufficiently precipitating the high-melting-point fraction.
[0060] The cooling rate is preferably 20°C / hour or less, and more preferably 0.1 to 15°C / hour, from the viewpoint of efficiently precipitating the high-melting-point fraction while preventing the incorporation of the target low-melting-point and medium-melting-point fractions into the crystal.
[0061] The cooling operation can be carried out by jacket cooling or a heat exchanger. The cooling operation can be carried out by standing or while stirring, but it is preferable to perform it while stirring in order to maintain good dispersion of the precipitated crystals and to cool the entire system uniformly. The addition or absence of a seeding agent can be selected as appropriate, and if added, it can be added at any time. For fractionation, the high-melting-point fraction crystals generated by cooling are filtered off by conventional methods, and then the solvent is removed by heating or other means to obtain the low-melting-point and medium-melting-point fractions.
[0062] (Fractionalization by crystallization) Crystallization refers to the process of cooling and crystallizing molten oil or fat, causing the crystalline portion to precipitate, and then separating it into a crystalline portion and a liquid portion.
[0063] The method of cooling and crystallizing is not particularly limited. For example, (1) cooling and crystallizing while stirring, (2) cooling and crystallizing while standing, (3) cooling and crystallizing while stirring, followed by further cooling and crystallization while standing, and (4) cooling and crystallizing while standing, followed by fluidization by mechanical stirring are possible. However, in order to obtain a crystallization slurry in which the crystalline portion and the liquid portion can be easily separated, it is preferable to adopt any of methods (1), (3), or (4), and more preferably method (1).
[0064] The crystallization temperature is preferably set at a temperature where the proportion of crystalline material in the crystallization slurry, i.e., the SFC (solid fat content) of the transesterified oil at the crystallization temperature, falls within the following ranges. Specifically, the SFC at the crystallization temperature is preferably 10-70%, more preferably 30-60%, and even more preferably 35-55%.
[0065] The cooling temperature and time are not particularly limited as long as the conditions are such that the SFC of the transesterified oil falls within the above range. However, by cooling the transesterified oil from a completely dissolved state to 25-60°C, preferably 30-50°C, over 30 minutes to 30 hours, and then holding it at that temperature for 30 minutes to 80 hours, preferably 1-70 hours, it is possible to preferably satisfy the above range of SFC.
[0066] In addition, in the crystallization of the present invention, when cooling the completely dissolved transesterified fat until it reaches the above range of SFCs, rapid cooling, slow cooling, or a combination of these methods may be used to adjust the SFC to the above range. However, in order to facilitate the separation of the crystalline portion and the liquid portion of the obtained crystallized slurry and to improve the yield of the obtained liquid portion, slow cooling is preferable below the temperature range in which the crystals of the transesterified fat precipitate.
[0067] In the present invention, when the transesterified oil is rapidly cooled, the cooling rate is preferably 5°C / hour or more, more preferably 5 to 20°C / hour, and when it is slowly cooled, the cooling rate is preferably 0.3 to 3.5°C / hour, more preferably 0.5 to 3.0°C / hour.
[0068] Here, below the temperature range in which crystals of the transesterified fat precipitate, it is preferable from the viewpoint of improving the yield of the fat (A-1) to go through a crystal maturation process for the crystals precipitated by cooling once or twice during the cooling process to a temperature in which a suitable SFC within the above range can be obtained. In the present invention, the crystal maturation process refers to an operation that makes the crystals more uniform and at the same time promotes further crystallization to create a crystalline state in which the crystalline part and the liquid part can be easily filtered apart, and as a result improves the yield.
[0069] Specifically, this involves maintaining a constant temperature of 25-60°C, preferably 30-50°C, for 30 minutes to 80 hours. There is no particular upper limit on the number of times the maturation process can be performed, but it is usually done 5 times, preferably 4 times.
[0070] The crystallization conditions are adjusted as appropriate depending on the composition of the transesterified oil to be crystallized. Preferred crystallization conditions include, for example, rapid cooling from a completely dissolved state to 44-50°C in 1-2 hours, followed by one or more aging steps at any temperature until a crystallized slurry is obtained at 32-43°C. It is preferable to perform the temperature transitions between each aging step by slow cooling.
[0071] Methods for separating the crystalline and liquid parts include natural filtration, suction filtration, press filtration, centrifugal separation, and combinations thereof. However, to simplify and efficiently perform the separation operation, it is preferable to select press filtration using a filter press or belt press. When transesterified oils and fats crystallize, if the solid fat content at the crystallization temperature is high, resulting in a highly viscous crystallized slurry or appearing lumpy, press filtration is particularly suitable because the pressure during press filtration will cause it to become a slurry.
[0072] When separation is performed by compressive filtration, the pressure is preferably 0.2 MPa or higher, more preferably 0.5 to 5 MPa. The pressure during compression may be gradually increased from the beginning to the end of compression, in which case the rate of pressure increase may be 1 MPa / min or less, preferably 0.5 MPa / min or less, and even more preferably 0.1 MPa / min or less.
[0073] As described above, oil and fat (A-1) can be obtained by solvent fractionation or crystallization.

A fat (A-1) content of 50% by mass or less is preferable because it makes it easier to realize oily confectionery with outstanding heat resistance and melt-in-the-mouth properties. The remainder of fat (A) may be fat (A-3). Therefore, in one preferred embodiment, fat (A) contains fat (A-1) in an amount of 10 to 60% by mass, with the remainder being fat (A-3).

A fat (A-2) content of 20% by mass or less is preferable because it makes it easier to realize oily confectionery with outstanding heat resistance and melt-in-the-mouth properties. The remainder of fat (A) may be fat (A-3). Therefore, in one preferred embodiment, fat (A) contains fat (A-2) in an amount of 5 to 30% by mass, with the remainder being fat (A-3).
[0112] In Embodiment 2, the content of S3 triglycerides of CN44 or higher is as previously described for oil (A), preferably 3% by mass or more, more preferably 4% by mass or more, and even more preferably 5% by mass or more, with an upper limit of preferably 15% by mass or less, more preferably 14% by mass or less, 12% by mass or less, or 10% by mass or less.

[0115] Furthermore, the preferred ranges for the total content of triglycerides with a CN of 44 or higher, the content of S2U triglycerides with a CN of 44 or higher, the content of SU2 triglycerides with a CN of 44 or higher, and the content of U3 triglycerides with a CN of 44 or higher are as previously described for oils and fats (A).
[0116] In Embodiment 2, the ratio SFC-25 / SFC-35 of oil (A) is as previously described for oil (A), but is preferably 5 or more, more preferably 5.5 or more or 6 or more, with an upper limit of preferably 9 or less, more preferably 8.5 or less, 8 or less or 7.5 or less.

[0118] The fat (A) used in the hard butter composition of the present invention is characterized in that, after being mixed with cocoa butter and seed tempered, it contains a certain amount or more of β-prime (β') type crystals when stored at 20°C.
[0119] In one embodiment, fat (A) is mixed with cocoa butter so that its content is 1 to 50% by mass, completely melted, and seed tempered. After standing at 15°C for 1 day and then at 20°C for 14 days, the proportion of β'-type crystals is 2% or more. The crystalline form of the fat can be measured by the method described in the "Measurement of the crystalline form of fat" section below.
[0120] The oily confectionery using the hard butter composition of the present invention can suppress the occurrence of cracks when a food product containing a thin film of the oily confectionery is manufactured. This is presumed to be because oily confectionery manufactured using fat (A) contains a certain amount of β'-type crystals, and when shrinkage occurs in the dense packing of β'-type crystals, the sparse packing of interposed β'-type crystals inhibits or mitigates the shrinkage, thereby suppressing the occurrence of cracks.
[0121] In addition to the fat (A) described above, the hard butter composition of the present invention may contain any auxiliary components within a range that does not impair the effects of the present invention or impair the flavor and texture of oily confectionery containing the hard butter composition of the present invention.
[0122] Examples of auxiliary components that the hard butter composition of the present invention may contain include emulsifiers, antioxidants, colorants, and flavorings.
[0123] Examples of emulsifiers include glycerin fatty acid esters, sucrose fatty acid esters, sorbitan fatty acid esters, propylene glycol fatty acid esters, glycerin organic acid fatty acid esters, polyglycerin fatty acid esters, polyglycerin condensed ricinoleic acid esters, calcium stearoyl lactylate, sodium stearoyl lactylate, polyoxyethylene fatty acid esters, polyoxyethylene sorbitan fatty acid esters, and lecithin.

The temperature of this oil and fat compound was adjusted to 90°C in a four-necked flask, and sodium methoxide was added at a ratio of 0.2 parts per 100 parts of the oil and fat compound. The mixture was then heated and mixed under vacuum for 1 hour. After this, citric acid was added to neutralize the sodium methoxide, and the mixture was purified by a conventional method to obtain oil and fat E-1 (hereinafter also simply referred to as "E-1"), which is a randomly transesterified oil and fat.
[0168] This E-1 was placed in a jacketed glass crystallization tank and heated to 70°C while stirring at 40 rpm until completely dissolved. Then it was rapidly cooled at 15°C / hour until the oil temperature reached 48°C, and a 4-hour maturation process was carried out at each of the following temperatures: 48°C, 44°C, and 42°C to obtain a crystallized slurry.

This produced tempered chocolate.
[0189] [Testing and Evaluation Methods] The following describes the testing and evaluation methods.
[0190] <Measurement of oil phase composition> The triglyceride (triacylglycerin) composition of the oil phase of the hard butter compositions and oily confectionery prepared in the examples and comparative examples was measured by high-performance liquid chromatography (HPLC) in accordance with the "Japan Oil Chemists' Society Standards for Analysis of Fats and Oils 2.4.6.2-2013".

Specifically, the samples (oil-based confectionery) were left to stand for 30 minutes in a constant temperature bath set to 1°C increments within the range of 25°C to 35°C. The surface of the samples was then touched with a finger to check for the presence of fingerprints and stickiness, and the lowest temperature at which fingerprints or stickiness occurred is shown in Table 3. In this test, a higher lowest temperature at which fingerprints or stickiness occurred is considered to indicate better heat resistance.
[0197] <Evaluation of melt-in-the-mouth properties of oily confectionery> The oil-based confectionery produced in the examples and comparative examples was subjected to sensory evaluation by 10 expert panelists according to the evaluation criteria below. The total scores of the 10 expert panelists were calculated, and the scores were assigned as follows: +++ for 45-50 points, ++ for 38-44 points, + for 30-37 points, - for 14-29 points, and -- for 0-13 points. The results are shown in Table 3. Prior to the evaluation, the panelists agreed on the degree of sensory evaluation corresponding to each score. Products with a score of "+" or higher were considered acceptable.
[0198] Melt-in-the-mouth evaluation criteria: 5 points: Excellent 3 points: Good 1 point: Slightly poor 0 points: Poor

[0201] In the case of tempered chocolate in which the oil phase consists solely of cocoa butter (CB), when food products containing a thin film of this chocolate were manufactured, it was confirmed that cracks occurred in half of the food products after 6 days of storage, and cracks occurred in all of the food products after 10 days of storage (Comparative Example 1). Furthermore, when tempered chocolates using hard butter compositions HB-8 to HB-10, in which the S3 triglyceride content of CN44 or higher and the monoacid-type S3 triglyceride content of CN44 or higher fall outside the scope of the present invention, and when food products containing a thin film of the chocolate were manufactured in the same manner, it was confirmed that cracking occurred in half of the food products after 6 to 10 days of storage, and cracking occurred in all of the food products after 13 days of storage (Comparative Examples 2 to 5). In contrast, oily confectionery manufactured using hard butter compositions HB-1 to HB-7, which have an S3 triglyceride content of CN44 or higher and a monoacid-type S3 triglyceride content of CN44 or higher within the range of the present invention, to satisfy conditions (1) and (2), showed no cracking after 6 days of storage, and even after 13 days of storage, there were 3 or fewer cracked products (Examples 1 to 11). In particular, it was confirmed that cracking was suppressed more effectively when a hard butter composition was used that contained at least a portion of fats and oils (A-1) or fats and oils (A-2) and resulted in tempered chocolate having (1) a S3 triglyceride content of CN44 or higher of 2.2% by mass or more, or (2) a hard butter composition that resulted in tempered chocolate having a total content of asymmetric triglycerides selected from the group consisting of PPO triglycerides, PStO triglycerides, and StStO triglycerides in the range of 2.5 to 5% by mass (Examples 3, 4, 6-11). Furthermore, it was confirmed that tempered chocolates using hard butter compositions HB-1 to HB-7 all exhibited good heat resistance (Examples 1 to 11).
[0202] Furthermore, it was confirmed that when a hard butter composition is used that results in tempered chocolate with SFC-25 / SFC-35 values in the range of 2 to 13 and SFC-25 / SFC-35 values in the oil phase in the range of 20 to 90, a good melt-in-the-mouth texture is easily achieved (Examples 1 to 10). In particular, for hard butter compositions containing at least a portion of fat (A-1), it was confirmed that exceptionally good melt-in-the-mouth properties can be achieved when the hard butter composition is used in an amount such that the fat (A-1) content in the oil phase is 10% by mass or less (Examples 2, 3, 5-8). Similarly, for hard butter compositions containing at least a portion of fat (A-2), it was confirmed that exceptionally good melt-in-the-mouth properties can be achieved when the hard butter composition is used in an amount such that the fat (A-2) content in the oil phase is 5% by mass or less (Examples 9, 10).
[0203] <Consideration 2> The behavior of the crystalline form of fats and oils during storage was investigated using hard butter compositions HB-1, 6, 7, 9, and 10.
[0204] First, the hard butter composition and cocoa butter were thoroughly mixed in a molten state according to the proportions shown in Table 4 (a formulation simulating the oil phase of oily confectionery in Study 1). The resulting mixture was cooled while stirring, and when the temperature reached 31.6-32°C, seeds (0.1% of the oil) were added, and seed tempering was performed by conventional methods. 10g of each mixture was filled into plastic cups, aged at 15°C for one day, and then stored at 20°C. The crystalline form of the fats and oils was measured at 1 day (D+1), 5 days (D+5), 10 days (D+10), and 14 days (D+14) using the method described below. The percentage of each crystalline form was determined based on the integrated intensity of the peaks derived from β-type and β'-type crystals. The results are shown in Table 4.
[0205] -Measurement of the crystalline form of fats and oils- The crystalline form of the oils and fats was measured using an X-ray diffractometer (Rigaku Corporation "RINT2000"). The various measurement conditions were as follows. (Short plane spacing of fat crystals) 2θ = 15~30 degrees (Sampling width) 0.02 (Scan speed) 6.00θ / min (Divergent slit) 1 degree (Divergence vertical limiting slit) 5mm (Scattering slit) 1 degree (Emitting slit) 0.3mm (Number of times accumulated) 3 times
[0206] [Table 4]
[0207] In formulation 1 (a formulation simulating the oil phase of the oily confectionery of Comparative Example 1), where the oil phase consisted solely of cocoa butter, the amount of β' crystals was less than 2% after a 14-day storage period. In formulations 5 and 6 (formulations simulating the oil phase of the oily confectionery of Comparative Examples 5 and 3, respectively), which used hard butter compositions HB-9 and HB-10, where the S3 triglyceride content of CN44 or higher and the monoacid-type S3 triglyceride content of CN44 or higher were outside the scope of the present invention, the amount of β' crystals was also less than 2% after a 14-day storage period. On the other hand, in formulations 2, 3, and 4 (formulations that simulate the oil phase of oily confectionery in Examples 1, 9, and 8, respectively) using hard butter compositions HB-1, HB-4, and HB-6, in which the S3 triglyceride content of CN44 or higher and the monoacid-type S3 triglyceride content of CN44 or higher are within the range of the present invention, the β' crystal content was generally 2% or higher after a storage period of 14 days. Considering the results of Study 1 and Study 2, it is presumed that oily confectionery made using the hard butter composition of the present invention contains a certain amount of β'-type crystals, and that when shrinkage occurs in the dense packing of β'-type crystals, the sparse packing of intervening β'-type crystals inhibits or mitigates the shrinkage, thereby suppressing the occurrence of cracks.
