[0015] [Figure 1] FIG. 1 is a diagram comparing the cross sections of peanut seeds when soaked or sprayed. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] Hereinafter, an embodiment of the present invention will be described in detail, but the present invention is not particularly limited thereto.

[0017] <Manufacturing method of peanuts> The method for producing peanuts of the present invention (hereinafter also simply referred to as the "production method of the present invention") includes the following two aspects. These aspects are common to each other except that the conditions for the spraying step are different. (First aspect) A spraying step of spraying water vapor of 65°C or higher onto the surface of a peanut seed including an embryo and a thin skin covering the surface of the embryo for 50 seconds to 400 seconds; After the spraying step, a peel separation step of separating the peel; Including, The manufacturing method of peanuts. (Second aspect) A spraying step of spraying water vapor at 65°C or higher onto the surface of a peanut seed including an embryo and a thin skin covering the surface of the embryo in an amount that results in a water absorption of 2g or more per 100g of the seed; After the spraying step, a peel separation step of separating the peel; Including, The manufacturing method of peanuts.

[0018] In all embodiments, the manufacturing method of the present invention includes a step of spraying water vapor onto the surface of peanut seeds. "Steam spraying" refers to spraying a mist of liquid (water) onto a target (in this invention, peanut seeds), and is clearly distinguished from "immersion," which involves immersing a target in liquid contained in a container or the like.

[0019] Conventionally, the thin skin of peanut seeds has been separated (removed) by immersing the skinned seeds in hot water to absorb water and soften them, and then using a peeling machine (roll type or vibrating type) or by hand peeling. However, the present inventors found that such soaking causes components contained in peanut seeds to flow out, such as water-soluble components such as sucrose and glutamic acid. Since sucrose and glutamic acid provide sweetness and umami, respectively, there is concern that the sweetness and umami of the seeds may be reduced when using conventional methods.

[0020] As a result of further investigation, the inventors have found that spraying water vapor at 65°C or higher under specified conditions, instead of immersing in hot water, can efficiently separate the thin skin of peanut seeds and also suppress the loss of components contained in the peanut seeds.

[0021] In the present invention, the "components contained in peanut seeds" are not particularly limited, but include components (particularly water-soluble components) that are normally contained in plant seeds (eg, embryo, pellicle, etc.). Specific examples include sucrose, glutamic acid, polyphenols, and the like.

[0022] In the present invention, "suppression of outflow of components contained in peanut seeds" encompasses suppression of a decrease in the content of components (particularly water-soluble components) contained in peanut seeds after spraying water vapor onto the peanut seeds, as compared to peanut seeds treated by conventional methods (e.g., immersion in hot water of 90°C or higher for 80 seconds or more). Whether the outflow of components contained in peanut seeds is being suppressed will be determined using high-performance liquid chromatography (HPLC) and sensors (chemical sensors, biosensors).

[0023] According to the present invention, the outflow of components (sucrose, glutamic acid, etc.) contained in the embryo of the peanut seed is suppressed, so that peanuts having a sweeter taste and tastiness than conventional peanuts can be obtained. Furthermore, according to the present invention, the outflow of components (such as polyphenols) contained in the skin of the peanut seeds is suppressed, so that the amount of useful components retained in the skin is greater than in the past.

[0024] The production method of the present invention will be described in detail below.

[0025] (peanut seeds) The production method of the present invention is a method for producing peanuts from peanut seeds.

[0026] "Peanut" (scientific name: Arachis hypogaea) is a plant of the genus Arachis in the subfamily Fabaceae, and refers to the entire plant including edible parts (seeds, etc.) and inedible parts (shells, pods, etc.).

[0027] In the present invention, the "peanut seed" refers to the main edible part of the peanut, and generally includes the embryo, the membrane, the cotyledons, and the like. The peanut seeds subjected to the production method of the present invention include an embryo and a thin skin covering a part or the entire surface of the embryo.

[0028] In the present invention, "peanut" refers to peanut seeds from which the thin skin has been peeled (mainly the embryo). However, this does not exclude the case where the thin skin is mixed in the peanuts obtained by the production method of the present invention.

[0029] The origin and variety of peanuts used in the present invention are not particularly limited.

[0030] The amount of peanut seeds to be subjected to the production method of the present invention is not particularly limited, and may be a small amount (one or a few) or a large amount (factory production level).

[0031] At the time of the spraying process, the peanut seeds are usually in a shelled state. From the viewpoint of easily achieving the effects of the present invention, it is preferable that the peanut seeds have not been subjected to any artificial steps (washing, etc.) other than the separation of the shells at the time of being subjected to the spraying step.

[0032] (Spraying process) The spraying step in each of the first and second embodiments will be described below.

[0033] [Spraying step in the first embodiment] In the first embodiment, water vapor at 65° C. or higher is sprayed onto the surface of peanut seeds for 50 to 400 seconds.

[0034] In the present invention, the "temperature of water vapor" may or may not be a constant temperature as long as the requirements of the present invention are satisfied.

[0035] In the present invention, the "spraying time of water vapor" refers to the total time for spraying water vapor onto the surface of peanut seeds, and the spraying time may be continuous or intermittent. In the case of intermittent spraying, the spray interval is adjusted so that the seed surface does not dry out, from the viewpoint of preventing drying of the thin skin.

[0036] By setting the temperature of the steam to 65°C or higher, the thin skins of the peanut seeds can be sufficiently absorbed, and the thin skins can be efficiently separated. The lower limit of the temperature of the water vapor is preferably 70°C or higher, more preferably 90°C or higher.

[0037] From the viewpoint of preventing deterioration of the peanut seeds and the outflow of ingredients (particularly sucrose, glutamic acid, and polyphenols), the temperature of the water vapor does not need to be excessive. The upper limit of the temperature of the water vapor is preferably 210°C or lower, more preferably 90°C or lower.

[0038] By setting the spray time of the water vapor to 50 seconds or more and 400 seconds or less, it is possible to allow the thin skin of the peanut seeds to sufficiently absorb water while suppressing the outflow of ingredients.

[0039] From the viewpoint of more efficient separation of the peanut seed membrane, the lower limit of the water vapor spray time is preferably 60 seconds or more, more preferably 180 seconds or more.

[0040] From the viewpoint of further suppressing the outflow of peanut seed components (particularly sucrose, glutamic acid, and polyphenols), the upper limit of the water vapor spray time is preferably 300 seconds or less, more preferably 240 seconds or less.

[0041] The total amount of water vapor sprayed onto the peanut seeds can be adjusted accordingly. From the viewpoint of more easily achieving the effects of the present invention, the total amount of water vapor sprayed onto the peanut seeds may satisfy the conditions of the spraying step in the second embodiment described below (i.e., an amount that results in water absorption of 2 g or more per 100 g of seeds).

[0042] [Spraying step in the second embodiment] In the second embodiment, water vapor at 65° C. or higher is sprayed onto the surface of peanut seeds in an amount that results in water absorption of 2 g or more per 100 g of seeds.

[0043] In the present invention, the "amount of water absorption" is determined by measuring the change in mass of the peanut seeds before and after water absorption. In other words, the increased mass of the peanut seeds after water absorption corresponds to the amount of water absorption.

[0044] By setting the temperature of the steam to 65°C or higher, the thin skins of the peanut seeds can be sufficiently absorbed, and the thin skins can be efficiently separated. The lower limit of the temperature of the water vapor is preferably 70°C or higher, more preferably 90°C or higher.

[0045] From the viewpoint of preventing deterioration of the peanut seeds and the outflow of ingredients (particularly sucrose, glutamic acid, and polyphenols), the temperature of the water vapor does not need to be excessive. The upper limit of the temperature of the water vapor is preferably 210° C. or lower, more preferably 95° C. or lower.

[0046] When the water vapor absorption amount is 2 g or more, the thin skin of the peanut seed can be sufficiently absorbed, and the thin skin can be efficiently separated. The lower limit of the water vapor absorption is preferably 2 g or more, and more preferably 4 g or more.

[0047] In order to prevent the outflow of peanut seed components (especially sucrose, glutamic acid, and polyphenols), the amount of water absorption is adjusted so as not to be excessive. The upper limit of the water absorption is preferably 7 g or less, more preferably 5 g or less.

[0048] The time for spraying the peanut seeds with steam can be adjusted appropriately. From the viewpoint of making it easier to achieve the effects of the present invention, the spraying time for the peanut seeds may satisfy the above-mentioned condition of the spraying step in the first embodiment (ie, 50 seconds or more and 400 seconds or less).

[0049] [Other conditions in the spraying process] In each of the first and second embodiments, other conditions in the spraying step are not particularly limited, and conditions conventionally known in the field of food production and the like can be adopted. For example, the following conditions may be adopted:

[0050] In the spraying step, water vapor is brought into contact with part or all of the surface of the peanut seeds. To facilitate contact, the spraying process may involve moving the steam nozzle and / or agitating the peanut seeds.

[0051] As a method for spraying water vapor, for example, a method using a steamer or a hose (connected to steam supplied from a boiler) can be adopted.

[0052] In the present invention, an embodiment in which the conventional method (thin skin separation by immersion) is carried out in addition to the spraying step in the present invention is not excluded. However, from the viewpoint of easily achieving the effects of the present invention, the manufacturing method of the present invention does not include a step of soaking peanut seeds, such as soaking in water (particularly hot water of 90° C. or higher) for 80 seconds or more.

[0053] (Thin skin separation process) After the spraying process, the peanut seeds are subjected to a dehulling process to separate the hulls. This process yields peanuts and skins separately.

[0054] The interval between the spraying step and the skin separation step is not particularly limited. However, the peanut seed membrane is easy to remove when it is in a softened state (i.e., when it has absorbed water from the spraying process). Therefore, it is preferable that the interval between the two steps is short enough to keep the membrane in a softened state. It is also preferable that no other steps are included between the two steps.

[0055] Methods for separating the thin skin include using a peeling machine (roll type or vibrating type) or peeling by hand.

[0056] After the skin separation step, drying or the like may be carried out as appropriate. The drying method is not particularly limited, but may be a method using an electric fan or the like.

[0057] After the skin separation step, the resulting peanuts can be consumed as is or can be further processed. The peanuts are inhibited from losing components (especially sucrose and glutamic acid) and have an excellent flavor (sweetness, umami, etc.).

[0058] After the peel separation step, the separated peel may be discarded or may be collected and stored. The thin skin prevents components (such as polyphenols) from leaking out, so it retains a greater amount of useful components than conventional skins. Therefore, the skin can be used as a source of useful components (such as polyphenols). For example, useful components can be obtained by subjecting the skin to extraction.

[0059] <Pretreatment method for peanut seeds> As described above, the spraying step in the present invention is useful as a method for allowing peanut seeds to absorb water while suppressing the outflow of components contained in the peanut seeds. Therefore, the present invention also encompasses a method for pretreating peanut seeds comprising the spraying step of the present invention (the spraying steps in the first and second aspects).

[0060] In the present invention, the term "pretreatment" includes pretreatment for peel separation.

[0061] <How to improve the flavor of peanuts> As described above, the spraying step in the present invention is useful as a method for suppressing the outflow of components contained in peanut seeds and improving the flavor of the resulting peanuts. Therefore, the present invention also encompasses a method for enhancing the flavor of peanuts, which comprises the spraying step of the present invention (the spraying step in the first and second embodiments) and also comprises a skin peeling step of separating the skin after the spraying step.

[0062] In the present invention, the "peanut flavor" includes the sweetness derived from sucrose and the like, the umami flavor derived from glutamic acid and the like, and the like.

[0063] <Method for preventing leakage of ingredients from the thin skin of peanut seeds> As described above, the spraying step in the present invention is useful as a method for suppressing the outflow of components contained in peanut seeds. Therefore, the present invention also includes a method for inhibiting the leakage of components from the peanut seed skins, which includes the spraying step of the present invention (the spraying step in the first and second aspects) and also includes a skin recovery step of recovering the skins after the spraying step. However, in the component outflow suppression method, the lower limit of the spraying time in the spraying step may be 20 seconds or more, preferably 30 seconds or more, more preferably 40 seconds or more, and even more preferably 50 seconds or more. In addition, it is preferable that the upper limit of the spraying time in the spraying step is not excessive from the viewpoint of suppressing the outflow of components, and for example, it may be preferably 400 seconds or less, more preferably 330 seconds or less, even more preferably 300 seconds or less, and even more preferably 180 seconds or less.

[0064] In the present invention, the "components of the peanut seed membrane" include polyphenols. EXAMPLES

[0065] The present invention will be described in more detail below with reference to examples, but the present invention is not limited to these examples.

[0066] <Peanuts production> Peanuts were prepared from peanut seeds in the following manner.

[0067] (1) Preparation of peanut seeds Peanuts were purchased with the shells on, and the shells were removed to remove the peanut seeds. Each seed contains an embryo and a membrane that covers the surface of the embryo.

[0068] (2) Steam spraying of peanut seeds Peanut seeds (100 g for each example) were placed on a net, and steam was applied evenly to the surface of the seeds using a hose connected to the boiler supply steam. The water vapor release rate was kept constant in each example. The temperature of the steam was set in the range of 50°C to 110°C (see the "Steam temperature" section in the table below). The spray time of steam on peanut seeds was set in the range of 30 seconds to 330 seconds (see the "Spray time" section in the table below).

[0069] Additionally, the amount of water vapor sprayed onto the peanut seeds was confirmed based on the amount of water absorbed immediately after spraying was completed. As a result, when the spray time of peanut seeds and steam was 50 seconds or more and the temperature of the steam was 65°C or higher, in all cases the amount of water absorbed was 2g or more (maximum about 5g) per 100g of seeds. On the other hand, when the peanut seeds were sprayed with steam for less than 50 seconds or when the temperature of the steam was less than 65°C, the amount of water absorbed was less than 2 g per 100 g of seeds in all cases.

[0070] The amount of water absorption was calculated by calculating the absorption rate based on the following formula, and the obtained value was specified as the amount of water absorption per 100 g of seeds. Water absorption rate (%) = (mass of peanuts immediately after spraying process - mass of peanuts before spraying process) / mass of peanuts before spraying process x 100

[0071] (3) Separation of the skin Immediately after spraying with water vapor, the membranes were separated from the peanut seeds by hand peeling to obtain peanuts. The separated skins were stored at room temperature until they were subjected to the following evaluation.

[0072] (4) Drying of peanuts The peanuts were dried with a fan until no longer moist and stored at room temperature until evaluated as described below.

[0073] <Various evaluations> The ease of separation of the skins during the peanut production process, and the resulting peanuts and skins were evaluated by the following methods.

[0074] (1) Ease of separating the skin In the peanut manufacturing process, the ease of separating the skin (ease of peeling the skin) in "(3) Separation of the skin" was evaluated according to the following criteria. The results are shown in Table 1.

[0075] [Criteria for ease of peel separation] ◎: The skin is very easy to peel off. 〇: The skin is easy to peel. △: The skin is relatively easy to peel. ×: The skin cannot be peeled off.

[0076] [Table 1]

[0077] As shown in Table 1, when spraying was performed under the conditions of the present invention, the thin skin was easily peeled off. In particular, the skin was easier to peel when the steam temperature was 70° C. or higher and the steam spray time was 60 seconds or longer. Furthermore, the skin was significantly easier to peel when the steam temperature was 90° C. or higher and the steam spray time was 180 seconds or longer.

[0078] On the other hand, when spraying was carried out in a state that did not satisfy the conditions of the present invention, the thin skin was difficult to peel off. In particular, when the steam temperature was below 65°C, the peanut seeds did not absorb enough water even when the spraying time was extended, and the skin did not soften, making it impossible to peel the skin. Furthermore, when the spraying time was less than 50 seconds, the peanut seeds did not absorb enough water even when the steam temperature was increased, and the skin did not soften, making it impossible to peel the skin.

[0079] (2) Peanut flavor The peanuts were eaten by a panel of experienced people, who responded to their flavor (sweetness and umami) according to the following criteria. The results are shown in Table 2.

[0080] [Peanut flavor standards] ◎: Strong sweetness and umami flavor. ◯: Sweetness and umami are noticeable. △: Sweetness and umami are slightly noticeable. ×: No sweetness or umami taste was observed.

[0081] [Table 2]

[0082] As shown in Table 2, when spraying was performed under the conditions of the present invention, the resulting peanuts had a sweet and umami taste. In particular, clear sweetness and umami were observed when the temperature of the steam was around 90° C. Also, clear sweetness and umami were observed when the spray time of the steam was 180 seconds or more and 240 seconds or less. Furthermore, when the temperature of the steam was around 90°C and the spray time of the steam was 180 seconds or more and 240 seconds or less, a significant sweetness and umami were observed. However, if the water vapor spray time was long, the components in the seeds were washed out, and the sweetness and umami flavor tended to decrease slightly.

[0083] On the other hand, when spraying was carried out in a state that did not satisfy the conditions of the present invention, the thin skin was difficult to peel in the first place, making it difficult to evaluate the sweetness and umami of the peanuts.

[0084] (3) Amount of polyphenols in the skin During the peanut manufacturing process, the amount of polyphenols in the skins collected in step (3) separation of the skins was measured using the Folin-Ciocalteu method. The amount of polyphenols in the skins of peanut seeds that had not been sprayed with steam (untreated skins) was also measured.

[0085] The measurement results obtained were evaluated according to the following criteria, and the results are shown in Table 3. However, no measurement was performed for cases in which the skin could not be separated at all. In Table 3, some of the measurement results for polyphenol content are shown in parentheses at the bottom of each column.

[0086] As a "control" (treatment based on the conventional method), during the peanut production process, instead of "(2) spraying steam onto peanut seeds," peanut seeds were placed in a container filled with hot water (90°C) and the entire peanut seeds were immersed in the hot water for 180 seconds, and the amount of polyphenols in the resulting skin was also measured. As a result, the amount of polyphenols was found to be 0% (i.e., no polyphenols remained in the skin).

[0087] [Standards for polyphenol content in skin] ⊚: The amount of polyphenols in the skin is 50% or more of the amount of polyphenols in the untreated skin. ◯: The amount of polyphenols in the skin is 30% or more and less than 50% of the amount of polyphenols in the untreated skin. △: The amount of polyphenols in the skin is 10% or more and less than 30% of the amount of polyphenols in the untreated skin, or the peanut has a bitter taste (transfer of polyphenols from the skin to the embryo). ×: The amount of polyphenols in the skin is less than 10% of the amount of polyphenols in the untreated skin, or the skin cannot be separated at all, or the peanut has a strong bitter taste (transfer of polyphenols from the skin to the embryo).

[0088] [Table 3]

[0089] As shown in Table 3, when spraying was performed under the conditions of the present invention, the amount of polyphenols remaining in the skin was high.

[0090] On the other hand, when spraying was carried out under conditions that did not satisfy the conditions of the present invention, not only was it difficult to peel the skin in the first place and difficult to recover the skin, but even if it was possible to recover it, the amount of polyphenol remaining in the skin was low.

[0091] <Reference: Conventional method> For reference, peanuts were prepared by separating the membrane from peanut seeds using the conventional method described below.

[0092] (1) Preparation of peanut seeds Peanut seeds were prepared in the same manner as described above in <Preparation of peanuts>.

[0093] (2) Soaking peanut seeds Peanut seeds were placed in a container filled with hot water (90°C) and the entire peanut seeds were immersed in the hot water for 180 seconds. When the amount of water absorbed after soaking was measured, it was found to be over 20 g per 100 g of seeds.

[0094] (3) Separation of the skin and drying of peanuts The skins were separated and the peanuts were dried in the same manner as in <Preparation of peanuts> above.

[0095] Evaluations were performed in the same manner as in the above <Various Evaluations>, and the results are shown in the "Conventional Method" section of Table 4. Note that "Invention" in Table 4 is the result in the above <Various Evaluations>, where the steam temperature was 90°C and the spray time was 180 seconds.

[0096] [Table 4]

[0097] As shown in Table 4, by satisfying the conditions of the present invention, not only is it easier to separate the skins, but compared to the "conventional method," the peanut flavor is enhanced and the leakage of polyphenols from the skins can be suppressed.

[0098] In addition, when the amount of components leaching from peanut seeds was measured using high performance liquid chromatography (HPLC), a significant decrease in the amounts of sucrose and glutamic acid was observed in the "conventional method" compared to before treatment (a 5-15% decrease in sucrose and a 1-5% decrease in glutamic acid). On the other hand, no changes in these amounts were observed in the "present invention."

[0099] In this example, the cross-sections of the peanuts of the "conventional method" and "present invention" in Table 4 were observed under an electron microscope to see whether they changed before and after immersion or spraying. The results are shown in FIG. As shown in Figure 1, the "conventional method" showed expansion of the cross section and numerous voids, whereas the "present invention" showed some voids, but there was little change from the cross section before spraying.
