Problems solved by technology

However, practice shows that the added chemical reagents: sulfite, citric acid, ascorbic acid (VC), boron, zinc compounds and bleaching powder, etc. have strong residual toxicity, which not only destroys the quality and process characteristics of starch, but also has poor effect and high price. , and the precipitation period is long, the utilization rate of equipment is low, and the product quality is poor

Embodiment Construction

[0009] 1. Cultivation process steps of Ojizi yeast bio-bacteria enzyme fermentation stock solution:

[0010] 1. Cultivation of mother liquor:

[0011] Select 300 grams of high-quality Koji Zizi yeast biological enzyme raw material, use 3000 grams of warm water, control the water temperature 35-40°C, put it in a container, dissolve the Koji Zizi yeast biological bacteria enzyme and stir it thoroughly, wait until the water temperature drops to and Cultivate at 18-22°C. When the biological live bacteria enzyme solution is cultivated until the pH value reaches 3.5-3.9, the biological live bacterial spore content in the biological live bacteria enzyme solution is more than 75%, and the preservation amount is more than 80%. , The mother liquor of biological live bacteria enzyme fermentation protoplasm was successfully cultivated, and 3300 grams of mother liquor was obtained.

[0012] 2. Cultivation in tanks:

[0013] Mix 3,300 grams of the mother liquor of biological live bacteria...

Abstract

The invention discloses a rapid sedimentation method of sweet potato starch. The method comprises the following steps of: fermenting and culturing traditional fork-made yeast lysozyme into mother liquor; then, fermenting and culturing into biological viable enzyme fermenting stock serosity; and mixing with a filtered sweet potato starch stock solution to rapidly sedimentate. By the invention, the sedimentation time of starch can be rapidly shortened from traditional 24 h to 5 min, the whiteness of the starch is improved by 7 percent, the purity is improved by 4 percent, the powder yield rate is improved by 1.5-2 percent, the daily production efficiency is improved by 6-8 times, and the market selling price of the starch is increased by 27.8 percent.

Description

Technical field: [0001] The invention relates to a starch precipitation technology, in particular to a rapid precipitation method of red taro starch. Background technique: [0002] Sweet potato is also known as glycoside potato, sweet potato, sweet potato, sweet potato, sweet potato, etc. Sweet potato is deeply loved by people because of its rich nutrition, rich in carotene, vitamin B1, B2 and vitamin C1, iron, calcium and other minerals necessary for the human body. Xishi, especially the food processed with red taro as raw material, has become a relatively fashionable health food, and is deeply favored by consumers. Sweet potato is not only the main food crop and economic crop, but also an important industrial raw material. Sweet potato contains a lot of starch and can be widely used in food industry, textile industry, paper industry, medicine and chemical industry. , maltose, fructose, glucose and other series of products as well as alcohol, liquor, citric acid, lactic ac...
