Description

[Technical field]

[0001] The present invention relates to a food tablet having excellent disintegrability while maintaining the hardness required for tablets, a method for improving the disintegrability of a food tablet containing a functional ingredient, and an agent for improving the disintegrability of a food tablet. [Background technology]

[0002] In recent years, due to factors such as irregular eating habits and increased awareness of beauty, there has been an increasing demand for food tablets such as nutritional supplements and dietary supplements that contain functional ingredients such as nutrients such as amino acids, vitamins, minerals, and extracts derived from plants and animal materials that contain various nutrients, in order to efficiently replenish necessary nutrients.

[0003] Disintegrants that can be used in the food tablets include sodium starch glycolate and croscarmellose sodium, which are food additives. Although there are no standards for the use of these disintegrants in pharmaceuticals, there are standards for the use of these disintegrants in foods, which state that they should be used at 2% by mass or less in the food. There is a problem in that some products are difficult to show sufficient disintegration when mixed at 2% by mass or less.

[0004] In addition, although partially pregelatinized starch and agar can be used as food ingredients without any usage standards, there is a problem that it is difficult to increase the blending amount to 10% by mass or 20% by mass because the raw material itself has poor binding properties, and increasing the blending amount reduces the tablet hardness. In addition, there is also a problem that at a certain blending amount, the function reaches a plateau and the effect according to the blending ratio cannot be exerted.

[0005] On the other hand, in the pharmaceutical industry, excipient raw materials that combine D-mannitol, sugar alcohol, crystalline cellulose, corn starch, lactose, etc. have been developed, and tablets with excellent disintegration properties have been provided as orally disintegrating tablets, but there is a problem that the tablet hardness is low and it is not suitable for distribution in food. In addition, some raw materials, such as D-mannitol, cannot be used in general food. Furthermore, there is a problem that the production of the excipient raw materials requires the use of a special granulator or a granulation process divided into several stages, making it a difficult technology to deploy in the food industry.

[0006] In addition, a solid oral composition containing insoluble natural plant fiber has been proposed as an oral solid composition that has the effect of removing tongue coating and strong effect of removing bad breath and is highly portable, but it does not relate to a technology for improving the disintegration property of food tablets (for example, see Patent Document 1).

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] (Food tablets) The edible tablet of the present invention contains at least a functional ingredient and a disintegration enhancer, and further contains other ingredients as necessary.

[0014] <Functional ingredients> The functional ingredient is not particularly limited, and ingredients used in dietary supplements and supplements can be appropriately selected depending on the purpose. Examples of the functional ingredient include vitamins such as vitamin A, vitamin B group, vitamin C, vitamin D, vitamin E, vitamin K, hesperidin, and inositol; amino acids or salts thereof; peptide-containing substances containing milk-derived peptides such as casein hydrolysates; peptide-containing substances containing animal-derived peptides such as chicken cartilage extract; peptide-containing substances containing plant-derived peptides such as maca extract and sesame extract; peptide-containing substances containing seaweed-derived peptides such as wakame extract and kombu extract; shark cartilage extract; and salmon nasal cartilage extract. Examples of such substances include peptide-containing substances such as peptide-containing substances containing peptides derived from fish, such as tuna extract and tuna extract; animal extracts such as placenta extract and collagen-containing extract; minerals such as calcium, magnesium, zinc, iron, manganese, copper, selenium, chromium, and molybdenum; coenzyme Q10, α-lipoic acid, L-carnitine, collagen, hyaluronic acid, elastin, turmeric, glucosamine hydrochloride, chondroitin sulfate, silymarin, lutein, fermented soybean germ extract powder, pomegranate extract powder, and the like; components containing various polyphenols derived from ginkgo leaves, apples, guava, tea, pine, grapes, and salacia; and the like. These may be used alone or in combination of two or more. As the functional component, commercially available products can be appropriately used.

[0015] The food tablet can be suitably used when it contains a hardly disintegrating component as the functional component. In the present invention, the term "difficult to disintegrate" refers to a tablet having a long disintegration time. For example, in the case of a tablet having a diameter of 8 mm, a radius of curvature (R) of 6.5 mm, and a weight of 200 mg per tablet, the tablet can be said to be difficult to disintegrate if the disintegration time is 10 minutes or longer when the tablet hardness is set to 70 N. The aforementioned difficult-to-disintegrate component refers to a component that, when formed into a tablet containing the component, takes a long time to disintegrate.

[0016] The non-disintegrating component is not particularly limited and can be appropriately selected depending on the purpose, and examples thereof include ginkgo leaf extract, bilberry extract, blueberry extract, salacia extract, components containing polyphenols such as apple polyphenols, turmeric extract, silymarin, hyaluronic acid, chondroitin sulfate, lutein, heme iron, collagen, vitamins, etc. These may be used alone or in combination of two or more.

[0017] As the functional component, commercially available products can be appropriately used.

[0018] The number of types of functional ingredients in the food tablet may be one type or two or more types, but according to the food tablet of the present invention, even when it contains two or more types of functional ingredients, the disintegration time is excellent, so that a large number of types of functional ingredients can be blended, for example, five or more types.

[0019] The functional component may or may not contain a hard-to-disintegrate component. When two or more types of functional components are contained, the content ratio of each functional component is not particularly limited and can be appropriately selected depending on the purpose.

[0020] The content of the functional ingredient in the food tablet is not particularly limited and can be appropriately selected depending on the purpose, but is preferably 5% by mass or more, more preferably 10% by mass or more, even more preferably 20% by mass to 80% by mass, and particularly preferably 30% by mass to 70% by mass. According to the food tablet of the present invention, even if a large amount of the functional ingredient is blended, the tablet can be made to have an excellent disintegration time.

[0021] The content of the non-disintegrating ingredient in the food tablet is not particularly limited and can be appropriately selected depending on the purpose, but is preferably 5% by mass or more, more preferably 10% by mass or more, even more preferably 20% by mass to 80% by mass, and particularly preferably 30% by mass to 70% by mass. According to the food tablet of the present invention, even if the blending amount of the non-disintegrating ingredient is large, it is possible to obtain a tablet having an excellent disintegration time.

[0022] <Disintegration improver> The disintegration enhancer is an insoluble dietary fiber. In the present invention, improving disintegrability means shortening the disintegration time of a tablet. The disintegration improver can be used as a supplement or a substitute for a known disintegrant.

[0023] In the present invention, the insoluble dietary fiber may be composed of only insoluble dietary fiber, or may be a mixture of insoluble dietary fiber and soluble dietary fiber. In the case of a mixture of insoluble dietary fiber and soluble dietary fiber, the insoluble dietary fiber content relative to the total amount of insoluble dietary fiber and soluble dietary fiber is 50% by mass or more. The insoluble dietary fiber refers to dietary fiber that is insoluble in water at 37°C.

[0024] The insoluble dietary fiber is not particularly limited and can be appropriately selected depending on the purpose, and examples thereof include citrus-derived dietary fiber, apple-derived dietary fiber, sugarcane-derived dietary fiber, locust bean gum, gellan gum, carrageenan, yeast-derived dietary fiber, etc. These may be used alone or in combination of two or more. Among the insoluble dietary fibers, at least one selected from the group consisting of citrus-derived dietary fiber, apple-derived dietary fiber, locust bean gum, gellan gum, and carrageenan is preferred, as it has better tablet hardness and disintegration properties, and citrus-derived dietary fiber is more preferred.

[0025] The citrus refers to a plant of the citrus family, and examples of the citrus family include lemon, lime, orange, iyokan, Uchimurasaki, Satsuma mandarin, Oobenimikan, Kabosu, Kishu mandarin, grapefruit, Sanbokan, Shikashya, citron, Sudachi, Tachibana, Bitter orange, Natsumikan, Navel, Hassaku, Hyuganatsu, Bergamot, Ponkan, Yuzu, and Kinkan. These may be used alone or in combination of two or more. Among these, lemon, lime, and orange are preferred in terms of superior tablet hardness and disintegration.

[0026] The apple refers to a plant of the genus Malus of the family Rosaceae, and examples of the plant of the genus Malus of the family Rosaceae include Apple, Apple Tree, and Apple Tree, etc. These may be used alone or in combination of two or more kinds.

[0027] As the insoluble dietary fiber, commercially available products can be appropriately used.

[0028] The content of the disintegration improver in the food tablet is not particularly limited and can be appropriately selected depending on the purpose, but is preferably 1% by mass to 50% by mass, more preferably 3% by mass to 30% by mass, and particularly preferably 5% by mass to 20% by mass. When the content of the disintegration improver is within the preferred range, a tablet having excellent disintegration property can be obtained while suppressing a decrease in tablet hardness.

[0029] When the food tablet contains two or more kinds of the disintegration improvers, the content ratio of each disintegration improver is not particularly limited and can be appropriately selected depending on the purpose.

[0030] The form of the disintegration improver is not particularly limited and can be appropriately selected depending on the purpose, and examples thereof include powder, granules (sometimes called granulated material), etc. Among these, granules are preferred in that they can further improve disintegration.

[0031] The particle size (D50) of the insoluble dietary fiber is not particularly limited and may be appropriately selected depending on the purpose, but is preferably 10 μm to 300 μm. If it is within the above preferred range, it is advantageous in that the mixing uniformity with other raw materials is good, and the raw materials are not crushed during the compression process when processing into tablets, resulting in excellent disintegration properties.

[0032] The mass ratio of the functional ingredient to the disintegration improver (disintegration improver / functional ingredient) is not particularly limited and can be appropriately selected depending on the purpose, but is preferably 0.01 or more, more preferably 0.05 or more, and particularly preferably 0.1 or more. If the mass ratio is within the preferred range, it is advantageous in that the disintegration property is more excellent.

[0036] <Method of manufacturing food tablets> The method for producing the food tablets is not particularly limited and can be appropriately selected depending on the purpose, but it is preferable to produce them by a method that includes at least a mixing step and further includes other steps as necessary.

[0037] <<Mixing process>> The mixing step is a step of mixing a functional component and a disintegration enhancer. In the mixing step, other components may be further mixed, if necessary.

[0038] The functional ingredient, the disintegration enhancer, and the other ingredients in the mixing step are the same as those described in the section (edible tablets) of the present invention above, and preferred embodiments are also the same.

[0039] In the mixing step, the functional ingredient, the disintegration improver, and, if necessary, the other ingredients may be mixed all at once, or any ingredient may be mixed in several batches.

[0040] The mixture obtained in the mixing step may be in the form of a powder or granules.

[0041] The mixing can be carried out using known devices, such as a container tumbler, a V-type mixer, or a Bohley container mixer. The mixing conditions such as temperature and time are not particularly limited and can be appropriately selected.

[0042] The granulation method is not particularly limited and may be appropriately selected from known methods, such as fluidized bed granulation, stirring granulation, dry granulation, and spray drying. Specific examples of the granulation method include a method in which the components are mixed, kneaded, kneaded, and / or stirred, and an appropriately selected binder is sprayed and / or added.

[0043] The binder is not particularly limited and can be appropriately selected depending on the purpose, and examples thereof include cellulose derivatives such as hydroxypropylmethylcellulose, hydroxypropylcellulose, and methylcellulose, thickening polysaccharides such as pullulan and guar gum, and sugar alcohols such as isomaltose, xylitol, maltitol, and sorbitol.

[0061] The present invention will be specifically explained below by way of test examples, but the present invention is not limited to these test examples.

[0062] (Test Example 1: Confirmation of the effect of differences in functional ingredients on disintegration properties) The following components were selected as functional ingredients, and tablets were manufactured at the blending ratios shown in Tables 1-1 to 1-4 below, and disintegration times were confirmed. Note that a tablet made of crystalline cellulose and calcium stearate was used as a control (tablet with good disintegration properties). In addition, for Test Example 1-3 (silymarin powder) and Test Example 1-4 (hyaluronic acid), the blending ratio was lower than that of other functional ingredients in consideration of fluidity. [Functional ingredients] Ginkgo leaf extract powder (manufactured by Dr. Willmar Schwabe GmbH & Co. KG) Turmeric extract powder (manufactured by Nippon Stange Co., Ltd.) Silymarin powder (manufactured by Indena SpA) Hyaluronic acid (manufactured by Nippon Shinyaku Co., Ltd.) Chondroitin sulfate (manufactured by Shanghai Huiwen Biotechnology Co., Ltd.) Bilberry extract powder (manufactured by Ningbo Green-Health Pharmaceutical Co., Ltd.) Lutein powder (manufactured by DSM Nutrition Japan Co., Ltd.) Heme iron (ILS Co., Ltd.) Salacia powder (manufactured by Takama Co., Ltd.) Vitamin Mixture (Vitamin A, Vitamin B1, Vitamin B2, Vitamin B6, Vitamin B 12 , Vitamin C, Vitamin E, Biotin, Niacin, Pantothenic Acid, Folic Acid, Vitamin P, and Inositol Mixture) Vitamin B complex (vitamin B1, vitamin B2, vitamin B6, vitamin B12 , a mixture of biotin, niacin, pantothenic acid, and folic acid) L-Ascorbic Acid (Northeast Pharmaceutical Group Co., Ltd.) Collagen (Rousselot Angouleme SAS) Calcium (scallop powder) (manufactured by NC Corporation) Glucosamine hydrochloride (manufactured by Yangzhou Koen Biotechnology Co., Ltd.)

[0063] <Tablet manufacturing> - Preparation of tablet powder - The ingredients shown in the following Tables 1-1 to 1-4 were mixed to prepare tablet powders.

[0064] -Tableting- Using a rotary tablet press (VEL5, manufactured by Kikusui Seisakusho Co., Ltd.), the tablet powder was packed and compressed at a pressure (tabletting pressure) of 7 kN, 11 kN, or 14 kN to obtain tablets with a diameter of 8 mm, a radius of curvature (R) of 6.5 mm, and a weight of 200 mg per tablet.

[0065] <Evaluation> -Tablet hardness- The hardness (N) of the tablets was measured using a fully automatic tablet measuring device Multicheck5.1 (manufactured by ERWEKA). The results are shown in Tables 1-1 to 1-4.

[0066] -Collapse Time- The disintegration time of the tablets was measured using a fully automatic disintegration tester ZT322 (manufactured by ERWEKA) using water as a solvent at a water temperature of 37° C. The results are shown in Tables 1-1 to 1-4.

[0067] [Table 1-1]

[0068] [Table 1-2]

[0069] [Table 1-3]

[0070] [Table 1-4]

[0071] Since a tablet weighing 200 mg is small, ingredients that take 10 minutes or more to disintegrate when the tablet hardness is 70 N can be said to be difficult to disintegrate. As shown in Tables 1-1 to 1-4, the control tablets had high tablet hardness, but the disintegration time was about 5 minutes, and it was confirmed that crystalline cellulose is a raw material with good disintegration properties. It was also confirmed that L-ascorbic acid, calcium (scallop powder), and glucosamine hydrochloride are also raw materials with good disintegration properties. On the other hand, the remaining ingredients had a long disintegration time, and were considered to be difficult to disintegrate. Tablets containing heme iron tend not to achieve tablet hardness, so they have a low hardness and appear to have a fast disintegration time, but when the tablet hardness is extrapolated to 70N and 100N, the disintegration time is approximately 30 minutes at 70N and approximately 48 minutes at 100N, showing a tendency for the disintegration time to be longer. Tablets containing turmeric extract powder have a high tablet hardness and a long disintegration time, but when the tablet hardness is extrapolated to 100N, the disintegration time is approximately 17 minutes, showing a tendency for the disintegration time to be longer.

[0072] (Test Example 2) The following ingredients were selected and examined as candidates for disintegration improvers.

Co., Ltd.) Locust bean gum (manufactured by San-Ei Gen F.F.I. Co., Ltd.)

[0083] <Tablet manufacturing> - Preparation of tablet powder - The ingredients shown in the following Tables 3-1 to 3-2 were mixed to prepare tablet powders.

[0084] -Tableting- Using a rotary tablet press (VEL5, manufactured by Kikusui Seisakusho Co., Ltd.), the tablet powder was packed and compressed at a pressure (tabletting pressure) of 7 kN, 11 kN, or 14 kN to obtain tablets with a diameter of 8 mm, a radius of curvature (R) of 6.5 mm, and a weight of 200 mg per tablet.

[0085] <Evaluation> The hardness and disintegration time of each tablet were evaluated in the same manner as in Test Example 1. The results are shown in Tables 3-1 and 3-2.

[0086] [Table 3-1]

[0087] [Table 3-2]

[0088] As shown in Tables 3-1 to 3-2, although the disintegration property was slightly inferior compared to the case of granulation (Test Example 2), it was confirmed that the disintegration property of the tablet was improved by the disintegration property improver of the present invention even when the tablet was mixed without granulation.

[0089] (Test Example 4) The effect of changing the blending ratio of the disintegration improver was examined. [Disintegration improver] Citrus-derived dietary fiber A (HelbaCel, manufactured by HerbaFood) Citrus-derived dietary fiber B (Citrify, Fiberstar)

[0090] <Granule manufacturing> The components were mixed and granulated to obtain the blending ratios shown in Table 4-1 below, and then dried at 60° C. for 12 to 18 hours to obtain Granules 4A to 4B.

[0096] [Table 4-3]

[0097] As shown in Tables 4-2 to 4-3, it was confirmed that disintegration improves by increasing the blending ratio of the disintegration improver. In addition, it was confirmed that there is no significant decrease in tablet hardness up to a blending ratio of 50% by mass when granulated, and up to a blending ratio of 25% by mass when not granulated, and that these are fully acceptable as products.

[0098] (Test Example 5) The effects of changing the blending ratio of the disintegration improver in the granules and changing the thickener in the granules were investigated. [Disintegration improver] Citrus-derived dietary fiber A (HelbaCel, manufactured by HerbaFood)

[0099] <Granule manufacturing> The components were mixed and granulated to obtain the blending ratios shown in Tables 5-1 and 5-2 below, and then dried at 60° C. for 12 to 18 hours to obtain granules 5A to 5F.

[0122] <Evaluation> The disintegration time of each tablet was evaluated in the same manner as in Test Example 1. The results are shown in Table 7-2.

[0123] [Table 7-2]

[0124] As shown in Table 7-2, it was confirmed that even in tablets containing functional ingredients different from those in Test Example 6, the disintegration time can be shortened while maintaining the tablet hardness by using the disintegration improver of the present invention.

[0125] (Test Example 8) The disintegration properties of tablets containing functional ingredients were examined.

[0126] <Tablet manufacturing> - Preparation of tablet powder - The ingredients shown in Table 8 below were mixed to prepare tablet powders. [Functional ingredients] Salacia extract powder (manufactured by Takama Co., Ltd.) [Disintegration improver] Citrus-derived dietary fiber A (HelbaCel, manufactured by HerbaFood) Citrus-derived dietary fiber B (Citrify, Fiberstar)

[0127] -Tableting- The powder was packed and compressed at a pressure (compression pressure) of 8 kN or 11 kN using a rotary tablet press (VEL5, manufactured by Kikusui Seisakusho Co., Ltd.) to obtain tablets with a diameter of 8 mm, a radius of curvature (R) of 6.5 mm, and a weight of 200 mg per tablet.

[0128] <Evaluation> The hardness of the tablets immediately after production was measured in the same manner as in Test Example 1. In addition, the disintegration time of each tablet was evaluated in the same manner as in Test Example 1, except that the tablets evaluated were those immediately after production (initial) and those stored at 50°C for 60 days. The results are shown in Table 8.

[0129] [Table 8]

[0130] As shown in Table 8, it was confirmed that the use of the disintegration improver of the present invention improves disintegration not only immediately after production but also over time.

[0131] (Test Example 9: Confirmation of the effect of differences in functional ingredients on disintegration properties - 2) The following ingredients were selected as functional ingredients, tablets were manufactured at the blending ratios shown in Table 9 below, and the disintegration time was confirmed. A tablet made of crystalline cellulose and calcium stearate was used as a control (tablet with good disintegrability). [Functional ingredients] Vitamin D preparation (importer: Shanghai Freeman Japan Co., Ltd.)

[0132] <Tablet manufacturing> - Preparation of tablet powder - The ingredients shown in Table 9 below were mixed to prepare tablet powders.

[0133] -Tableting- Using a single punch tablet press (fully automatic powder molding machine AutoTab-200, manufactured by Ichihashi Seiki Co., Ltd.), the tablet powder was packed and compressed at a pressure (tabletting pressure) of 5 kN, 8 kN, or 11 kN to obtain tablets with a diameter of 8 mm, a radius of curvature (R) of 6.5 mm, and a weight of 200 mg per tablet.

[0134] <Evaluation> -Tablet hardness- The hardness (N) of the tablets was measured using a fully automatic tablet measuring device Multicheck5.1 (manufactured by ERWEKA). The results are shown in Table 9.

[0135] -Collapse Time- The disintegration time of the tablets was measured using a fully automatic disintegration tester ZT322 (manufactured by ERWEKA) at a water temperature of 37° C. as the solvent. The results are shown in Table 9.

[0136] [Table 9]

[0137] As described above, since a tablet weighing 200 mg is small, a raw material that takes 10 minutes or more to disintegrate when the tablet hardness is 70 N can be said to be a hardly disintegrating ingredient. As shown in Table 9, the control tablets had a high tablet hardness, but the disintegration time was about 5 minutes, confirming that crystalline cellulose is a raw material with good disintegrability. On the other hand, when the tablet hardness of the tablet of Test Example 9 containing vitamin D was extrapolated to 70N and 100N, the disintegration time was approximately 27 minutes at 70N and approximately 33 minutes at 100N, showing a tendency for the disintegration time to be longer, and it was considered that vitamin D is a difficult-to-disintegrate ingredient.

[0138] (Test Example 10) The effect of using a vitamin D preparation (similar to that used in Test Example 9) as the difficult-to-disintegrate component and citrus-derived dietary fiber A (HelbaCel, manufactured by Herba Food Co., Ltd.) as the disintegration enhancer was examined.

[0139] <Tablet manufacturing> The ingredients shown in the following Tables 10-1 to 10-2 were mixed to prepare tablet powders.

[0140] -Tableting- Using a single punch tablet press (fully automatic powder molding machine AutoTab-200, manufactured by Ichihashi Seiki Co., Ltd.), the tableting powder was filled and compressed under pressure (tabletting pressure) adjusted so that the tablet hardness was in the average range of 155N to 160N, to obtain tablets with a diameter of 8 mm, a radius of curvature (R) of 6.5 mm, and a weight of 200 mg per tablet.

[0141] <Evaluation> The hardness and disintegration time of each tablet were evaluated in the same manner as in Test Example 9. The results are shown in Tables 10-1 and 10-2.

[0142] [Table 10-1]

[0143] [Table 10-2]

[0144] As shown in Tables 10-1 to 10-2, by incorporating the disintegration improver of the present invention, even tablets incorporating vitamin D exhibited disintegration properties equivalent to those of sodium starch glycolate, and it was confirmed that the disintegration properties of the tablets were improved.
