However, the large amount of starch contained in itself has not been really extracted and fully utilized, and there are fewer research reports on buckwheat starch. According to research, buckwheat starch made from buckwheat starch is suitable for making instant soup. , can replace the current special imported modified starch, and the instant soup made with it has a first-class quality effect, and its rehydration speed is stronger than that of the special modified starch

Embodiment
[0018] A kind of production method of buckwheat starch, concrete steps are as follows:
[0019] 1. Soaking: Put the buckwheat rice in a sodium sulfite solution with a pH of 5-6. The soaking time is 18 hours in summer and 20 hours in winter. The soaking temperature is 40-45°C, and the soaking solution is adjusted with 1.0mol / L hydrochloric acid The pH value is 2-3; the weight ratio of soaking liquid to buckwheat is 2.5-4.5:1.
[0020] 2. Refining and sieving: remove the soaking liquid from the soaked buckwheat rice, wash it with clean water, grind it with distilled water at a ratio of 1:8-10 with a needle mill, and use a 0.088mm sieve for sampling Sieve, grind the filter residue repeatedly for 4-6 times, combine the pulp and milk, and pass through a 200-mesh sieve; separate the filter residue, and rinse it with clean water;
[0021] 3. Protein separation: Add 10% HCl solution to the combined fine milk after sieving to precipitate, centrifuge at a speed of 5000r / min for 10min, ...

Abstract
The invention discloses a production method for buckwheat starch. According to the production method, the problem that in the buckwheat starch production process, protein and the starch cannot be effectively separated is solved, and the buckwheat protein is retained while the starch quality is guaranteed; in addition, the production method is easy to operate, stable, low in worker labor intensity, lower in production cost and suitable for industrial scale production; basic physical and chemical indicators of the buckwheat starch obtained through the method reach or even exceed those of first-class edible starch.
Description
technical field [0001] The invention relates to a production method of starch, in particular to a production method of buckwheat starch. Background technique [0002] Buckwheat, also known as ebony, flower wheat, and triangular wheat, is an annual perennial plant of Liaceae. The planting area and output of buckwheat in my country rank second in the world. Buckwheat has rich nutritional quality. According to expert determination, buckwheat contains 10%-18% protein, 10%-16% cellulose, 70% starch, but only about 2% fat. Buckwheat is also rich in phosphorus, iron, calcium, magnesium, copper and other minerals and organic acids such as citric acid, oxalic acid, malic acid and vitamin C, B, BZ, E, etc., and the content is generally higher than Wheat flour, rice, sorghum flour, cornmeal and millet. Buckwheat has high medicinal and health value. Buckwheat has a wide spectrum of medicines and significant curative effects. It has the functions of widening the intestines and smoothi...
