Embodiment

[0021] The fresh waste residue produced by Laiwu Citric Acid Factory in summer is used as raw material, and the acid-reducing bacteria are fermented bacteria, which are taken from the laboratory of Tianjin University of Science and Technology. The species are fermented under the condition of no bacteria pollution by supplying oxygen through the oxygen supply wind and controlling the temperature. The specific production steps are:

[0022] Cultivate strains for production in the laboratory of the factory, take an inoculation needle and a slanted strain, insert it into a 250ml Erlenmeyer flask with 60ml liquid medium, shake and supply oxygen, 20°C, 24 hours, to obtain first-grade seeds 10% inoculum was transferred to a 500ml Erlenmeyer flask filled with 100ml of liquid culture medium, oscillating oxygen supply, 20°C, 24 hours to obtain a secondary seed solution, and then inoculated at 10% (w / w) Add a large amount of solid medium with citric acid waste residue as raw material (s...

Abstract

The invention discloses a process for preparing biological degradable dietary fabric powder by using citric acid waste slag as raw material and acid-degrading bacteria as the zymogeneous bacteria. The process consists of subjecting citric acid waste slag to high temperature germicidal treatment, introducing acid-degrading bacteria by the proportion of 8-15%, letting in oxygen supply and controlling temperature for fermentation and degradation of residual citric acid.

Description

technical field [0001] The invention belongs to the technical field of biological applications, in particular to a method for producing high dietary fiber powder by biodegrading citric acid waste residue and residual acid. Background technique [0002] Dietary fiber is a plant component contained in food that cannot be decomposed by human gastrointestinal digestive enzymes, including pectin, hemicellulose, cellulose, and lignin. The main functions of dietary fiber are: 1. Improve intestinal function, improve the obesity caused by excessive diet in the digestive tract; 2. Balance the flora, eliminate "toxins" and discharge "waste", prevent constipation, and prevent colon cancer; 3. Lower cholesterol and regulate blood sugar levels; 4. Prevent heart disease caused by coronary atherosclerosis. Research on dietary fiber at home and abroad and its consumption situation: In western developed countries, there has been research on consumption. The United State...
