Description

Description: TECHNICAL FIELD OF THE INVENTION The present invention relates to a method for producing a dietary fiber-containing food, and more specifically, a plant fiber composed of corn pulp, bran and rice bran, which has conventionally been unsuitable to eat. By inoculating and culturing the mycelium of Enokitake (Flammulia Velutipes) to improve the flavor and make it easier to eat, the plant fiber contained in these is decomposed into edible dietary fiber by the degrading enzyme of Enokitake. The present invention relates to a method for producing a dietary fiber-containing food.

Technical background of the invention and its problems Dietary fiber is a colorectal cancer, diverticulosis, and constipation that is considered to occur frequently in association with westernized dietary habits (high intake of meat, fats and oils, dairy products, sugar, etc.). In particular, it has recently attracted attention as a new nutrient for preventing non-infectious diseases such as intestinal diseases such as ischemic heart disease, arteriosclerosis, diabetes, and cholelithiasis, so-called civilization diseases. That is, dietary fiber stimulates digestive tract, increases fecal volume, shortens digestive tract transit time, affects intestinal bacteria, affects digestive absorption of nutrients and intestinal circulation, and suppresses rapid rise in blood glucose. It is recognized that it has various physiological actions such as.

Here, the plant fiber refers to a polysaccharide which constitutes a cell tube of a plant and is hard to be digested by human digestive enzymes, and a lignin and also a storage polysaccharide which is also hard to be digested contained in cells.

Examples of abundant sources of vegetable fiber include vegetable fiber, and specific examples thereof include corn pulp, bran, rice bran, and various other types of cereal bark and lees. However, since these vegetable fibers are hard and inferior in flavor, they cannot be eaten as they are and cannot be ingested unless they are processed by some method.

The present inventors surprisingly inoculate and cultivate the enokitake mushroom hyphae on plant fiber that cannot be ingested as it is, and surprisingly, the flavor of the plant fiber is improved by the assimilation ability of the enokitake mushroom, and the plant fiber is The present invention has been completed by discovering that it becomes a vegetable fiber-containing food that is decomposed by its assimilating ability and becomes soft, and that it has an excellent flavor and an active ingredient by addition of the expression of the taste component inherent to enokitake mushrooms.

OBJECT OF THE INVENTION The present invention has been made to solve the problems associated with the prior art as described above, and is excellent in flavor from plant fiber consisting of corn pulp, bran and rice bran, and a plant containing a sensible or active ingredient. It is intended to provide a method for producing a fiber-containing food.

SUMMARY OF THE INVENTION The method for producing a plant fiber-containing food according to the present invention is a method of inoculating and culturing a solid medium containing plant fiber consisting of corn pulp, bran and rice bran with Enoki mushroom and cultivating the enzyme (assimilating ability). The plant fiber is characterized in that it is decomposed, the culture is crushed after the completion of the culture, and dried. The plant fiber-containing food thus obtained is ingested as it is or in a mixture with other foods.

DETAILED DESCRIPTION OF THE INVENTION The method for producing a plant fiber-containing food according to the present invention will be specifically described below.

In the present invention, a medium containing plant fiber is used as the solid medium. Vegetable fibers as a solid medium include, for example, corn pulp, sugar cane pomace (bacus), bran (wheat germ), rice bran (rice germ), other grain germs, fallen epidermis, legume peels, and defatted. Soybeans, okara, buckwheat husks, residual pulp obtained after juice extraction, dried mushrooms,
Dried vegetables, grains, etc. may be used alone or as a mixture. Among them, there is a mixture of corn pulp, bran, and rice bran, and a solid medium containing corn pulp 30 to 80% by weight, bran 10 to 40% by weight, and rice bran in an amount of about 5 to 20% by weight. Is particularly preferable. When such a solid medium is used, a vegetable fiber-containing food excellent in flavor and mouthfeel can be obtained.

When the Enokitake hyphae are inoculated into the solid medium, the solid medium preferably contains water, and the water content of the solid medium is 30 to 80% by weight, preferably about 40 to 70% by weight.

The solid medium is preferably sterilized by heating before inoculation with Enokitake hyphae. Specifically, the solid medium containing water is filled in a heat-resistant plastic container provided with a vent and sterilized under high pressure. (About 100 to 130 ° C. for about 3 to 7 hours) is also preferable.

In the present invention, the enokitake hyphae are inoculated into the above solid medium. Enokitake mycelia can be obtained, for example, by aseptically collecting fruiting bodies of Enokitake mushrooms and culturing a part of the fruiting bodies on an agar medium. It is also possible to use the thus obtained Enokitake hyphae which have been further cultured for about 1 month in a mixed medium consisting of sawdust and rice bran.

In the present invention, enokitake is used as the fungus body,
When fungi other than enokitake are used, it is not possible to obtain a plant fiber-containing food having a good flavor, such as a musty odor in the culture.

The inoculum of Enokitake hyphae on the solid medium is preferably about 10 to 50 g, preferably about 20 to 30 g per kg of the medium.

After inoculating the enokitake hyphae into the solid medium as described above, the enokitake fungi are cultured. This culture is usually
5 to 20 ° C, preferably 7 to 15 ° C in a culture room where sunlight is shielded
It is desirable to carry out in a moderate temperature range. At the end of culture,
It is preferable that the mycelium of Enokitake mushrooms is just before the fruiting body or just after the fruiting body, and the culture period is usually about 1 to 1.5 months after the start of the culture. When culturing is completed at this time, a plant fiber-containing food containing a large amount of active ingredients can be obtained, because the decomposing power of enokitake hyphae for plant fibers is the best.

When the enokitake mushroom mycelium is cultured in a solid medium containing plant fibers in this manner, it is considered that the plant fibers are assimilated and the aleurone layer in the plant cells is decomposed, and water-soluble hemicellulose is obtained. Therefore, the plant fiber-containing food obtained in the present invention contains water-soluble plant fibers in addition to water-insoluble plant fibers.

After cultivating the enokitake mycelium in the solid medium as described above, the solid medium is dried and crushed, or the solid medium is crushed and dried, and the water content is about 20% by weight or less, preferably about It is 10% by weight or less, more preferably about 5% by weight or less.

The plant fiber-containing food thus obtained, in addition to the water-insoluble plant fiber, water-soluble plant fiber as described above,
The active ingredients of enokitake mushroom mycelium, for example, polysaccharides and various proteins are also contained as they are, and they are extremely preferable foods for health.

Effects of the Invention As described above, according to the method for producing a plant fiber-containing food according to the present invention, corn pulp, which was only used as a conventional feed or fertilizer, from plant fiber consisting of bran and rice bran, has a good flavor, Moreover, it is possible to easily and inexpensively obtain a high-quality plant fiber-containing food which has a good mouth feel and which contains a large amount of active ingredients. The plant fiber-containing food thus obtained may be ingested as it is, or may be ingested by adding it to other foods, and may be a food useful for promoting human health as described below. Be expected.
