Embodiment 1

[0026] Example 1: Cultivation of CGMCC No. 1903 strain

[0027] Disinfect the surface of the freeze-drying tube where the strains are stored, open one end, inject 10°BX wort liquid medium, and cultivate and activate at 25°C for 48 hours. After the yeast is seen to sprout and grow, it is inoculated on the wort agar slant, and cultured at 25°C to 30°C for 2 to 3 days, and so on repeatedly until the bacteria grow thriving. The slope is synthesized from malt extract, yeast extract, peptone, glucose, and agar. Transfer the thriving strains to liquid test tubes, small Erlenmeyer flasks, and large Erlenmeyer flasks for cultivation, and increase the concentration of the medium to 12°BX in the Erlenmeyer flask. Then enter the pasteurized tank, the Kaspersky tank, the Hansheng tank, the yeast seed culture tank, and the propagation tank in sequence. The tank needs to be filled with sterile air. When the "log phase" is about to pass, the cultured mash will be discharged out of the tank.

Embodiment 2

[0028] Example 2: Preparation of nutritional powder

[0029] (1) Mix the mash cultured in Example 1 with dry wheat powder in a ratio of 1:2, quickly dry at low or normal temperature, pulverize, and pass through an 80-mesh sieve to obtain the undersize.

[0030] (2) Prepare a solid mixture, which contains the following ingredients per 1,000,000 parts by weight: 150,000 calcium, 80,000 ascorbic acid, 45,000 potassium, 1200 magnesium, iron 1300, zinc 1000, riboflavin 200, dietary fiber 500, vitamins A 100, thiamine 65, niacin 70, vitamin E 40, manganese 30, folic acid 18, selenium 2, vitamin D 0.6, and the rest are carbohydrates. The addition forms of calcium, potassium, magnesium, iron, zinc, manganese, and selenium are calcium carbonate, potassium chloride, magnesium gluconate, iron EDTA, zinc sulfate, manganese carbonate, and sodium selenite. Carbohydrates are added in the form of starch.

[0031] (3) Mix the undersize material obtained in (1) with the solid mixture obtained in (2) ...

Embodiment 3

[0032] Example 3: Effect analysis of nutritional powder

[0033] In order to understand the actual effect of the nutritional powder of the present invention on the physical growth and health of children, 10 kindergartens (1 in Xicheng District, 6 in Chaoyang District, and 3 in Huairou District) were selected as the edible group in Beijing. Eat the nutritional powder of the present invention. In each district, the conditions similar to those of eating the nutritional powder of the present invention were selected (food expenses and living conditions are similar, the composition of boys and girls in the kindergarten is roughly the same, and the age composition is roughly the same), but a total of 10 kindergartens that did not consume the nutritional powder of the present invention were selected as the control group. compare research. In March 2006, the Preschool Children's Health Management Department of Beijing Maternity and Child Health Hospital calculated the physical examinatio...

Abstract

The invention provides a vintage yeast strain CGMCC No.1903, and the strain is obtained from fermenting dough, and is bred by monospore separating method, under high acid value condition that PH valueis 2-4, after strong electromagnetic oscillation action, and under the repeatedly alternate actions of zero DEG C and 40 DEG C temperatures. The invention also provides a method which uses the yeaststrain to prepare nutritious powder. The produced nutritious powder contains comprehensive nutrient contents, can be eaten separately as nutritious food, as well as can be added to rice, steamed breadand dish as the food additive. Long-term consumption of the yeast strain plays a positive role on improving the nutrition level, strengthening the immunity and promoting the body of child to growth.

Description

Technical field [0001] The invention relates to a strain of Saccharomyces cerevisiae and its application in nutritional products. Background technique [0002] At present, there are a dazzling variety of nutritional varieties on the market, but most of them only provide one or a few nutrients needed by the human body, which is not conducive to the comprehensive balance and absorption of various substances in the human body. With the continuous improvement of people's living standards, higher requirements are put forward for the edible nutritional components of nutritional products. [0003] Yeast is an early type of microorganisms that have been used in human practice. It is rich in a variety of nutrients necessary for the human body. It is an excellent source of vitamins and protein. It can provide rich protein, nucleic acid, vitamins and multiple enzymes, and has no toxic side effects. . How to select high-quality nutritional yeast strains and apply them to the development of n...
