[0036] Now take the laboratory implementation as an example, and the non-limiting examples are described as follows:

[0037] (1) Preparation of seed liquid by microbial fermentation method:

[0038] ① Preparation of mold seed solution:

[0039] Weigh 1gKH 2 PO 4 , 2gNaNO 3 , 0.5gKCl, 0.01gFeSO 4 , 0.5gMgSO 4 ﹒ 7H 2 O and 30g glucose, dissolved in 1000ml pure water, put into 250ml Erlenmeyer flasks and pack into 10 bottles. High-pressure steam sterilization at 121°C for 20 minutes to prepare mold seed liquid culture medium. Inoculate Trichoderma or Aspergillus strains, and culture at a constant temperature of 28±0.5°C for 5 days with shaking to make seed liquid for later use.

[0040] ②Preparation of lactic acid bacteria seed solution:

[0041] Weigh 100g of skimmed milk powder, dissolve in 1000ml of pure water, put into 250ml Erlenmeyer flasks and pack into 10 bottles to prepare lactic acid bacteria seed liquid culture medium, and sterilize by autoclaving ...

Abstract

The invention relates to a technology for preparing a dietary fiber by a microbial fermentation method. The technology comprises the steps of taking waste scraps generated in a processing procedure of a bamboo shoot as a raw material, and performing fermentation seed liquid preparation, raw material treatment, raw material fermentation substrate preparation, inoculation, fermentation, vacuum freeze drying and the like to form a finish product of the bamboo shoot dietary fiber. The final product is natural in color, delicate in taste and fragrant in smell, a soluble dietary fiber content, water-holding power and swelling power are increased to various extents, and the technology can be put into industrial production. The technology is simple in operating condition and reliable in method, realizes comprehensive utilization of bamboo shoot resources, and increases a production added value of the bamboo shoot.

Description

technical field [0001] The invention belongs to the field of comprehensive utilization of agricultural and sideline products, and relates to a technology for preparing dietary fiber by performing microbial fermentation treatment on bamboo shoot processing waste. Background technique [0002] Dietary fiber (DF) refers to the general term for edible plant ingredients, carbohydrates and similar substances that can resist digestion and absorption in the small intestine of the human body, but can be partially or completely fermented in the large intestine. According to its solubility in water, it can be divided into two categories: insoluble dietary fiber (IDF) and soluble dietary fiber (SDF). [0003] IDF refers to the part of DF that is not digested by human digestive tract enzymes and is insoluble in water. It mainly includes cell wall components, including cellulose, hemicellulose, lignin, protopectin and chitosan, among which lignin is Aromatic hydrocarbons that keep cell w...
