Problems solved by technology

The enzymatic method is to use a variety of enzymes to remove other components in the raw materials except dietary fiber one by one, and finally obtain dietary fiber. This method is more costly than the chemical method, and the operation is more cumbersome.
There are few reports on the preparation of dietary fiber by membrane separation method. This method is to prepare dietary fiber with different molecular weights by changing the molecular interception of the membrane. The disadvantage is that insoluble dietary fiber cannot be prepared, and this method requires high equipment requirements.

Embodiment 1

[0063] The Pleurotus ostreatus dietary fiber prepared by the Yazhi Mucor radiata fermentation method is prepared according to the following steps:

[0064] Mucor actinosa can be pre-cultured on PDA slant medium. The weight composition of the PDA slant medium is as follows: 2.0% glucose, 15.0% potato, 5.0% wheat bran, 2.0% agar, and the balance of water. The preparation method is as follows: boil potato slices and wheat bran for 20 minutes, filter with four layers of gauze, discard the filter residue, add glucose and agar into the filtrate, add water, keep the pH natural, 0.1MPa, and sterilize at 121°C for 30 minutes. Mucor actinosa can be pre-cultured on the PDA slant medium for a period of time.

[0065] A, the cultivation of the mucormyces radiata species: the composition of the strain culture medium by weight: cross 3.0% of Pleurotus ostreatus powder of 80 mesh sieves, 2.0% of glucose, 1.0% of peptone, KH 2 PO 4 0.2%, MgSO 4 .7H 2 O 0.1%, water balance; pH natural, 0....

Embodiment 2

[0081] Utilize the method for preparing bread of above-mentioned oyster mushroom stalk dietary fiber, its step comprises:

[0082] A. Kneading the dough: fully mix the dietary fiber of Pleurotus ostreatus with flour, yeast, and milk powder, wherein the dietary fiber of Pleurotus ostreatus is added in a weight ratio of 3-9%, add water and stir until the dough is moderately soft and hard, with good elasticity, toughness and Moderate extensibility and dry and smooth surface;

[0083] B. Cut into pieces: Cut the reconciled dough into (50-150) grams / block;

[0084] C. Kneading round: Knead the divided noodles into a uniform spherical shape, so that the gluten network structure damaged by cutting can be repaired, and carbon dioxide can be discharged, so that the yeast can reproduce and ferment, and at the same time, it can also distribute various ingredients. more uniform;

[0085]D. Fermentation: Put the rounded dough in a fermentation box with a temperature of 38-40°C and a rela...

Embodiment 3

[0089] Utilize the method for preparing cake of above-mentioned oyster mushroom stalk dietary fiber, its step comprises:

[0090] A. Beating: add eggs, sugar, horizontal mushroom stalk dietary fiber into the mixer, beat at high speed for 3-7 minutes to increase the volume to 2.5-3.5 times the original, and the egg liquid is milky white fluffy and foamy as a whole; The added amount of dietary fiber of mushroom handle is 3-7%;

[0091] B. Mixing: Add the sifted flour evenly into the beaten egg liquid in the mixer, stir for 1 minute, and mix evenly to obtain cake batter; take part of the cake batter to measure the specific gravity, and put the remaining cake batter into the mould;

[0092] C. Pour into the mold: After mixing the batter, pour it into the small round baking mold, the pouring amount is 2 / 3 of the volume of the baking mold; before pouring the mold, evenly coat the inner wall of the baking mold with vegetable oil;

[0093] D. Baking: Baking is carried out immediately...

Abstract

The invention discloses pleurotus stem dietary fiber prepared with an actinomucor elegans fermentation method. The method comprises the following preparation steps of: A, culturing an actinomucor elegans strain; B, fermenting actinomucor elegans to prepare pleurotus stem dietary fiber: adding 10 percent by volume of the strain obtained in the step A into a mixed liquid of pleurotus stem powder and water, culturing in ventilated state, and fermenting at the temperature 26-30 DEG C to obtain a zymotic fluid; and C, performing after-treatment on the zymotic fluid, wherein the after-treatment mainly comprises a homogenizing step for homogenizing the zymotic fluid under the pressure 120 MPa. The invention further provides a method for preparing a nutritional food or beverage from the obtained pleurotus stem dietary fiber. According to the invention, efficient recycling of pleurotus stems is realized.

Description

technical field [0001] The invention relates to the technical field of comprehensive utilization of oyster mushroom stalks. Background technique [0002] Pleurotus ostreatus is an edible fungus with the largest cultivation area in the world, the most mature production and cultivation technology, high biological efficiency, and relatively good economic benefits. It is also one of the four major edible fungi with the largest cultivation area in my country. Edible fungi play an important role in people's daily life and economic life, and the edible fungi industry has become a pillar industry in agriculture. In the process of export processing and commercialization of oyster mushrooms, the stalks must be cut off. my country alone produces millions of tons of oyster mushroom stalks every year, and this part of resources is very huge. Pleurotus stipe and fruiting bodies are also formed by differentiation of mycelium, rich in effective biologically active ingredients. The value i...
