Problems solved by technology

[0005] In the prior art, there is no control over the nucleic acid and nucleic acid content of yeast, which causes some people to suffer from gout after eating this kind of product, which brings great pain to consumers
[0006] Concentrated salt method and dilute alkali method can extract the nucleic acid in yeast, but these methods cause serious nutritional loss of yeast, and the produced yeast has no edible or health value

Embodiment 1

[0027] Take Angel Saccharomyces cerevisiae produced by Angel Yeast Co., Ltd., add deionized water, and prepare a solution with a mass percent concentration of 5%; adjust the yeast solution to pH=6.0 with sulfuric acid and sodium hydroxide; then, the yeast The solution was incubated at 60°C for 1 hour; then adjust the yeast solution to pH = 5.0; separate with a laminated separator, collect the separated heavy phase, then add water to the obtained heavy phase, the amount of water added is the same as the volume of the obtained heavy phase, and stir After 30 minutes, use a separator to separate, and spray-dry the resulting heavy phase to obtain a low-nucleic acid yeast sample 1 # .

Embodiment 2

[0029] Take the Angel beer yeast produced by Angel Yeast Co., Ltd., add deionized water, and prepare a solution with a mass percentage concentration of 7%; adjust the yeast solution to pH=9 with sulfuric acid and sodium hydroxide; then, the yeast The solution was incubated at 80°C for 4 hours; then adjust the yeast solution to pH = 6.0; separate with a laminated separator, collect the separated heavy phase, then add water to the obtained heavy phase, the amount of water added is the same as the volume of the obtained heavy phase, and stir After 30 minutes, the separator was used for separation, and the resulting heavy phase was drum-dried to obtain low-nucleic acid yeast sample 2 # .

Embodiment 3

[0031] Take the yeast for Angel noodles produced by Angel Yeast Co., Ltd., add deionized water, and prepare a solution with a mass percentage concentration of 5%; adjust the yeast solution to pH=6.0 with sulfuric acid and sodium hydroxide; then, the The yeast solution was incubated at 60°C for 1 hour; then the yeast solution was adjusted to pH=7.0; the separated heavy phase was collected with a laminated separator, and then water was added to the heavy phase obtained, the amount of water added was the same as the volume of the heavy phase obtained, After stirring for 30 minutes, separate with a separator, and spray-dry the resulting heavy phase to obtain a low-nucleic acid yeast sample 1 # .

Abstract

The invention relates to a low nucleic acid yeast product and a preparation method thereof. The low nucleic acid yeast product comprises 45 percent to 55 percent of protein, 0.05 percent to 1.0 percent of nucleic acid, 100ppm to 5,000ppm of calcium, 30ppm to 1,000ppm of iron, and 30ppm to 1,000ppm of zinc. The invention further relates to the preparation method of the low nucleic acid yeast product. The preparation method comprises the following steps: yeast is mixed with water into a solution with a mass percentage concentration of 5 percent to 10 percent; the pH (hydrogen ion concentration)of the solution is regulated to a value between 6.0 and 10.0; the heat of the yeast solution is preserved for 1 to 6 hours at a temperature of 60 DEG C to 100 DEG C; the pH of the yeast solution is further regulated to a value between 5.0 and 7.0; the yeast solution is separated, washed and dried; and then the low nucleic acid yeast product is acquired. The method disclosed by the invention has the advantages that the nucleic acid content in the yeast is reduced simply, conveniently and effectively, namely the danger of gout caused by eating the yeast or relevant products produced by using the yeast as a raw material is reduced, and the nutritive value in the original yeast is preserved. The invention further relates to a weight-reducing product comprising the low nucleic acid yeast. The weight-reducing product has the advantages of low calorie, high nutrition, safety and effectiveness, and can promote lipolysis.

Description

technical field [0001] The invention relates to a low-nucleic acid yeast product and a preparation method thereof, as well as a slimming product comprising the low-nucleic acid yeast. Background technique [0002] As a kind of food, yeast began to enter people's daily life, and more and more yeast products came out. Most of the yeast foods on the market now use the beer yeast mud after beer production as raw materials to develop into different foods. The existing technology is mainly to make nutrient supplements by debittering the beer yeast and then directly drying it for human consumption, or strengthening some minerals and trace elements before drying. [0003] In recent years, many people have reported that gout is easily induced after eating such products, and the main ingredient that causes gout is nucleic acid. The nucleic acid content in yeast is generally about 5%. After eating products with this yeast as the main raw material, it is easy to cause gout. Nucleic a...
