Problems solved by technology

Although these methods have achieved the purpose of increasing the content of resistant starch, new substances have been introduced into the raw materials, and the preparation process is relatively complicated.
Although the complete miscellaneous bean cells contain a large amount of resistant starch, it has been proved by experiments that the miscellaneous bean cells will not be fermented by intestinal microorganisms after entering the large intestine, the fermentation rate is extremely slow, and the fermentation products only contain a small amount of short-chain fatty acids

Embodiment 1

[0045] The preparation method of the mixed bean dietary fiber for regulating the fermentation of intestinal flora to produce gas and acid comprises the following steps in sequence:

[0046] 1) Take mature and plump kidney beans, soak them in excess water for 12 hours, the ratio of solid to liquid is 1:15, and the unit is g / ml;

[0047] 2) After soaking and absorbing water, the kidney beans are washed and peeled, and boiled in tap water or pure water at 50°C for 1 hour, the ratio of material to liquid is 1:2, and the unit is g / ml; after boiling, mash to make kidney bean puree;

[0048] 3) Kidney bean paste is added with tap water or purified water, the ratio of material to liquid is 1:7, the unit is g / ml, and passed through a 80-mesh sieve once to obtain coarse kidney bean particles and coarse kidney bean slurry;

[0049] 4) The kidney bean coarse slurry in step 3) is passed through a 275-mesh sieve once, and the residue on the sieve is collected and dried to obtain kidney bean...

Abstract

The invention discloses a mixed bean dietary fiber and an enzymic method preparation method and application thereof. The mixed bean dietary fiber is prepared from mixed bean cells without cell walls.Plant cell wall Viscozyme L is used for degrading cell walls of mixed beans, the mixed beans include other beans except for soybeans, such as kidney beans, chick peas, mung beans and red kidney beans.The preparation method saves energy and is environmentally friendly; compared with mixed bean starch, the fermentation speed of mixed bean dietary fiber is slower under the in-vitro fermentation condition, fermentation lasts longer, the amount of butyrate generated within 24 h is similar to that of mixed bean starch, the number of Firmicutes bacteria can be specifically increased, the number of bacteroidetes and fusobacteria bacteria is restrained, and the prebiotic function of preventing and treating various metabolism related diseases can be brought into play.

Description

technical field [0001] The invention relates to the field of soybean dietary fiber, in particular to a soybean dietary fiber and an enzymatic preparation method and application thereof. Background technique [0002] Dietary fiber refers to the sum of edible plant components, carbohydrates and similar substances that cannot be digested and absorbed by the small intestine of the human body but fermented in the large intestine. According to its solubility, it is generally divided into two categories: soluble and insoluble dietary fiber. Dietary fiber is rich in vegetables, fruits, and legumes, including cellulose, hemicellulose, lignin, and pectin. Dietary fiber plays a very important role in maintaining the health of the digestive system. Adequate intake of dietary fiber can clean the digestive wall of the intestinal tract, enhance digestion and dilute and accelerate the excretion of carcinogens and toxic substances in food. Resistant starch acts like dietary fiber and is co...
