Problems solved by technology

Though this kind of chromium acetate yeast has improved the biotransformation rate of organic chromium and the content of bioactive chromium, but, because the raw material that this patent adopts is liquid chromium, its content is relatively low, and consumption is bigger in actual production, and transportation, Storage is inconvenient; in the production process, the yeast sludge is difficult to dry and pulverize, the production cost is high, the cultivation period is long, and the residual chromium content in the culture medium is high, which is not conducive to the treatment of waste liquid

Embodiment 1

[0014] 1. Preparation of malt powder

[0015] 1) Select 25Kg of wheat grains, place them in a chromium chloride solution with a concentration of 50-1500 μg / ml for cultivation, the ratio of wheat to liquid is 1:0.5-0.7, and the cultivation temperature is 10-25° C., and cultivate for 72 hours;

[0016] 2) Stir once every 2 hours to keep the solution evenly absorbed;

[0017] 3) When the malt grows 2-4mm, take it out and wash it 2-3 times, and let it dry naturally;

[0018] 4) Dried malt is crushed, passed through a 60-80 mesh sieve, and set aside.

[0019] 2. Preparation of yeast

[0020] 1) using wort to make the culture medium of yeast cells, the sugar content is 9-11 Pauline medium, and chromium chloride is added in the culture medium;

[0021] 2) Inoculating the yeast with a volume ratio of 1:1 between the culture medium and the yeast, the chromium concentration is 5-100 ppm, and culturing at 15-30° C. for 24 hours;

[0022] 3) The chromium-enriched yeast is separated by...

Abstract

The preparation method of chromium-enriched yeast containing malt powder for improving sugar tolerence includes the following steps: 1. preparing chromium-enriched malt powder, culturing malt in chromium chloride or chromium sulfate solution, drying by airing and pulverizing for stand-by; 2. preparing chromium-enriched yeast, using malt wort or basic culture medium, adding chromium chloride or chromium sulfate, inoculating yeast, culturing and extracting for stand-by; 3. combining the above-mentioned chromium-enriched malt and chromium-enriched yeast paste so as to obtain the invented product with the health-care functions of reducing sugar and reducing blood fat, etc.

Description

technical field [0001] The invention relates to a preparation method of chromium-rich yeast containing malt powder which can improve sugar tolerance. Background technique [0002] Chromium is an essential trace element in animals and humans. Chromium in the body binds to proteins, nucleic acids, and various low-molecular weight ligands, participates in the body's sugar and lipid metabolism, and promotes the growth and development of the human body. In the modern food refining process, a large amount of chromium loss in food is caused. For example, the chromium content of flour is lost by 40%, granulated sugar is lost by 93%, rice is lost by 75%, and corn oil is lost by 72%. Insufficient chromium content. With the growth of age, the chromium content of the human body decreases, which leads to the occurrence of various diseases in the human body, especially for diabetics, who need to control their diet, and the intake of chromium decreases accordingly, thus forming a vicious ...
