Description

[Technical Field]

[0001] The present invention relates to a gelatin-containing composition and its use. [Background technology]

[0002] Gelatin is non-toxic to the human body, inexpensive, and has excellent jelly-forming properties, thickening properties, etc. For these reasons, gelatin is widely used in the fields of medicine, food, etc.

[0003] Gelatin is usually used after swelling with water. For example, Patent Document 1 discloses a method for producing soft candies containing gelatin, in which gelatin that has been previously swollen with water is mixed with other ingredients to produce the soft candy.

[0004] However, because gelatin is used after swelling with water, it is very difficult to mix with oil-based ingredients such as fragrances. Therefore, surfactants are used to facilitate mixing. However, even when surfactants are used, separation of the gelatin and oil-based ingredients may occur, and separation of the oil-based ingredients is particularly likely to occur under high temperatures, such as in a car in summer, resulting in poor dispersibility.

[0027] The form of the gelatin-containing composition is not limited, and may be any of liquid, semi-solid (gel (jelly), cream, paste, etc.), solid (powder, granules, etc.), etc.

[0028] The present gelatin-containing composition is prepared by adding at least one flavoring selected from the group consisting of β-ionone and γ-decalactone, calcium lactate, and hydroxypropyl ... The composition can be prepared by appropriately mixing sodium, gelatin, and, if necessary, the other components described above.

[0029] Although not limiting the present invention, for example, the present gelatin-containing composition may be produced by mixing gelatin and water to prepare a mixture, then mixing at least one flavor selected from the group consisting of β-ionone and γ-decalactone, and then mixing calcium lactate, and further mixing the other components as needed during each mixing. Furthermore, although not limiting the present invention, for example, the present gelatin-containing composition may be produced by mixing gelatin and water to prepare mixture A, separately mixing at least one flavor selected from the group consisting of β-ionone and γ-decalactone and calcium lactate to prepare mixture B, then mixing mixtures A and B to prepare mixture C, and further mixing the other components as needed during the preparation of each of mixtures A to C.

[0030] Furthermore, if necessary, the thus-obtained mixture containing gelatin, at least one flavor selected from the group consisting of β-ionone and γ-decalactone, and calcium lactate can be molded, dried, etc. to produce the present gelatin-containing composition. The molding may be any desired shape, such as a football shape, oblong shape, round shape, teardrop shape, triangle shape, diamond shape, sheet shape, etc., and the molded product may be cut into pieces as necessary after molding.

[0031] Examples of such formed products include gummy candy, jelly, bavarois, etc. The present gelatin-containing composition may further be coated with a sugar coating, etc. Coating may also be carried out according to a method conventionally known in the art.

[0032] Furthermore, the gelatin-containing composition may be used as a capsule coating (soft capsules, hard capsules) as a shaped product. When the gelatin-containing composition is used as a capsule coating, the contents encapsulated in the coating are not limited and may be appropriately determined depending on the purpose. For example, pharmaceutically acceptable ingredients, cosmetically acceptable ingredients, edible ingredients, etc. may be arbitrarily selected and used, with edible ingredients being preferred. The contents may be encapsulated in the coating according to procedures conventionally known in the art.

[0033] The present gelatin-containing composition may be used either orally or parenterally, and is preferably used orally. The use mode of the present gelatin-containing composition is not limited and may be appropriately determined depending on the purpose. Examples of the use mode when the composition is used orally include food compositions (including beverages, health functional foods (including specified health foods, nutrient functional foods, functional food products, supplements, etc.), health supplements, and foods for the sick), pharmaceutical compositions, quasi-drug compositions, feed compositions, and additives to food compositions, pharmaceutical compositions, quasi-drug compositions, feed, etc. The present gelatin-containing composition may be, for example, swallowed immediately, or may be left in the oral cavity for a certain period of time and then swallowed.

[0034] The subject to which the present gelatin-containing composition is applied (ingested, administered, etc.) is not limited, and examples thereof include humans and non-human mammals. Examples of non-human mammals include guinea pigs, rabbits, dogs, cats, monkeys, chimpanzees, etc.

[0035] According to the present gelatin-containing composition, by using 10 parts by mass or less of calcium lactate per 1 part by mass of at least one flavor selected from the group consisting of β-ionone and γ-decalactone in a gelatin-containing composition, the dispersibility of the flavor in the composition can be improved. In particular, although separation of the flavor is likely to occur under high-temperature conditions of 50°C or higher, the present gelatin-containing composition can improve the dispersibility of the flavor in a gelatin-containing composition even under high-temperature conditions of 50°C or higher. From this perspective, according to the present invention, for example, a gelatin-containing composition that is solid or semi-solid at room temperature (25°C) can be dissolved in water at a temperature of 50°C or higher. Even if the gelatin-containing composition becomes liquid under high temperature conditions, its thermal stability is enhanced and a decrease in dispersibility in the composition can be suppressed. Therefore, according to the present invention, a gelatin-containing composition having high thermal stability can be provided.

[0036] From this, it can be said that the present invention also provides a method for improving the dispersibility of a flavoring in a gelatin-containing composition, characterized in that the gelatin-containing composition contains at least one flavoring selected from the group consisting of β-ionone and γ-decalactone and calcium lactate, with the calcium lactate being contained in an amount of 10 parts by mass or less per 1 part by mass of the flavoring.

[0037] In this method, the gelatin, at least one flavoring selected from the group consisting of β-ionone and γ-decalactone, calcium lactate, etc. are the same as those described above. [Example]

[0038] The present invention will be described in more detail below with reference to examples, but the present invention is not limited to these examples.

[0039] Test Example 1 Preparation of Gelatin-Containing Compositions Gelatin stock was prepared by adding water to gelatin (product name BLK200, manufactured by Nitta Gelatin Co., Ltd.) according to the composition in Table 1, swelling for 5 minutes, and then dissolving the gelatin in a water bath at 80°C. Also, β-ionone was mixed with a surfactant (Poem K-37V, manufactured by Riken Vitamin Co., Ltd. (organic acid monoglyceride (citric acid monoglyceride))) according to the composition in Table 1 and sonicated to completely dissolve β-ionone. Water was then added to the resulting solution to disperse it, preparing a flavor stock. The gelatin stock in which the gelatin had completely dissolved and the flavor stock were mixed, and the resulting mixture was stirred with a spatula until visually uniform, preparing a gelatin / flavor stock. Separately, calcium lactate stock was prepared by adding water to calcium lactate (product name Calcium Lactate Pentahydrate (L-type calcium lactate), manufactured by Taihei Chemical Industry Co., Ltd.) according to the composition in Table 1 and stirring.

[0040] Next, the gelatin / flavoring stock obtained as described above was added to a screw tube (35 mm x 65 mm), and calcium lactate stock was further added and stirred thoroughly. The gelatin / flavoring stock and calcium lactate stock were added to the screw tube in amounts of 20 g in total according to the contents in Table 1. That is, in Table 1, the contents of all components are shown in grams (g). In Example 1, the stocks were mixed to the ratios shown in Table 1 to prepare gelatin-containing compositions, and 20 g of each was placed in a screw tube. In this way, the gelatin-containing compositions of Examples 1 to 5 and Comparative Examples 1 and 2 were prepared.

[0041] Dispersibility evaluation The obtained gelatin-containing composition was placed in a capped screw tube and stored at room temperature (25°C) for at least 2 hours, and then left to stand in a constant temperature setting of 50°C for one week.

[0042] After leaving it for one week, the gelatin-containing composition in the screw tube was observed from the side, and as shown in Figure 1, the length of the total layer (height of the gelatin-containing composition) and the length of the separation layer were each measured with a ruler, and the length of the separation layer relative to the length of the total layer (length of separation layer / length of total layer) was calculated. The obtained value was used as the ratio of the separation layer, and the degree of separation inhibition was determined according to the following criteria to evaluate dispersibility.

[0043] Judgment criteria: ◎ The ratio of the separated layer is less than 0.05 ○ The ratio of the separated layer is 0.05 or more and less than 0.15 △ The ratio of the separated layer is 0.15 or more and less than 0.2 × The ratio of the separated layer is 0.2 or more The results are shown in Table 1.

[0044] [Table 1]

[0045] As shown in Comparative Example 1 in Table 1, a composition containing β-ionone and gelatin but not calcium lactate was evaluated as × (separation layer ratio 0.21). Furthermore, as shown in Comparative Example 2 in Table 1, a composition containing gelatin in which 14.16 parts by mass of calcium lactate was added per 1 part by mass of β-ionone was also evaluated as × (separation layer ratio 0.5). In contrast, as shown in Examples 1 to 5 in Table 1, by using a specific ratio of calcium lactate to β-ionone in a composition containing gelatin, it was possible to suppress the separation that occurred in Comparative Examples 1 and 2. This demonstrates that the dispersibility of β-ionone can be improved in a gelatin-containing composition by using a specific ratio of calcium lactate to β-ionone.

[0046] Test Example 2 Preparation of Gelatin-Containing Compositions A gelatin stock was prepared by adding water to gelatin (the same as in Test Example 1) according to the composition in Table 2, allowing it to swell for 5 minutes, and then dissolving the gelatin in a water bath at 80°C. Also, γ-decalactone and a surfactant (the same as in Test Example 1) according to the composition in Table 2 were mixed and ultrasonicated to completely dissolve the γ-decalactone. Water was then added to the resulting solution to disperse it, preparing a flavor stock. The gelatin stock in which the gelatin had completely dissolved and the flavor stock were mixed, and the resulting mixture was stirred with a spatula until visually uniform, preparing a gelatin / flavor stock. Separately, a calcium lactate stock was prepared by adding water to calcium lactate (the same as in Test Example 1) according to the composition in Table 1, and stirring.

[0047] Next, the gelatin / flavoring stock obtained as described above was added to a screw tube (the same as in Test Example 1), and calcium lactate stock was further added and stirred well. The amounts of gelatin / flavoring stock and calcium lactate stock added to the screw tube were the same as in Test Example 1, and they were added to the screw tube in the proportions shown in Table 2 so that the total amount was 20 g. In this way, the gelatin-containing compositions of Examples 2 to 10 and Comparative Examples 3 and 4 were prepared.

[0048] Dispersibility evaluation In the same manner as in Test Example 1, the dispersibility was evaluated.

[0049] The results are shown in Table 2.

[0050] [Table 2]

[0051] As shown in Comparative Example 3 in Table 2, a composition containing γ-decalactone and gelatin but not containing calcium lactate was evaluated as × (separation layer ratio 0.21). Furthermore, as shown in Comparative Example 4 in Table 2, a composition containing gelatin in which 14.16 parts by mass of calcium lactate was added per 1 part by mass of γ-decalactone was also evaluated as × (separation layer ratio 0.5). In contrast, as shown in Examples 6 to 10 in Table 2, by using calcium lactate at a specific ratio relative to γ-decalactone in a composition containing gelatin, it was possible to suppress the separation that occurred in Comparative Examples 3 and 4. This demonstrates that the dispersibility of γ-decalactone in a gelatin-containing composition can be improved by using calcium lactate at a specific ratio relative to γ-decalactone.
