Embodiment 1

[0034] Embodiment 1 preparation of edible mushroom liquid strain

[0035] Put the Yunzhi preserved in the refrigerator on the potato slant for activation, and cultivate for 8 days. After the mycelia cover the slant, take the slant block and put it into a 250ml shaker flask filled with 100ml of potato medium for liquid culture. The rotational speed is 120-150 r / min, and cultured at 26° C. for 4 days to obtain edible fungus seed liquid. Embodiment 2 liquid fermentation produces active dietary fiber

Embodiment 2

[0036] 120g of dried potato dregs, 8g of bran, and 1L of water were added to form a fermentation medium, and the edible fungus seed liquid prepared in Example 1 was added according to the volume fraction v / v of 9%. Fermented under the condition of 120r / min for 4 days, the total dietary fiber content of the fermented product reaches more than 60g / l.

Embodiment 3

[0037] Embodiment 3 solid fermentation sweet potato dregs produces active dietary fiber

[0038] Dry kudzu root dregs 100g bran 10g, cake 3g, add 200ml of water to form a fermentation medium, after conventional sterilization, add the edible fungus seed liquid prepared in Example 1 by volume weight fraction v / v as 10%, at a temperature of 26°C, Fermented under the condition for 8 days, the total dietary fiber content of the fermented product reaches more than 65%.

Abstract

The invention discloses a technical way of primary processing of germ. After stem's primary processing, put draff in water, then do the liquid and solid ferment. Then do the deeper processing. It perfects the making of germ, and it can form a work of no pollution. Effectively solve the problem that germ making is difficult and pollution is heavy, has the distinct economy and socil functions.

Description

【Technical field】 [0001] The invention relates to a microbial technology deep processing method for the primary processing residue of tubers, in particular to a method for producing active dietary fiber by using the microbial technology deep processing technology for the primary processing residue of tubers. 【Background technique】 [0002] Tuber substances are the enlarged roots and stems of plants, which are important material forms for plants to fix solar energy. Tuber plants are mostly potatoes or traditional Chinese herbal medicines, and tuber plants account for the vast majority. These plants store nutrients through underground tubers, so starch is an important component of tuber agricultural products. In addition to starch as its important component, tuber substances also contain different active ingredients depending on the variety, and are used as health products or supplements to food crops in practical applications. [0003] In the primary processing of tubers, es...
