Problems solved by technology

The cultivation of natural yeast requires a special place and corresponding storage methods, so it is inconvenient to transport, the fermentation power is weaker than that of dry yeast, and the fermentation time is longer
Even if the natural yeast liquid is refrigerated at 1-5°C, it will lose its vitality and cannot be used after 3-5 days of cultivation.
At present, the most suitable method for preserving natural yeast in the world is to use a drum desiccant and treat it with a "low temperature drying method". However, due to the huge investment in equipment, this method will not be considered except for large yeast manufacturing enterprises. use this method
[0006] Moreover, Panettone yeast in Italy is a natural yeast that contains a lot of lactic acid bacteria. The bread produced is sour, and it is basically not used in China. The amount of domestic yeast is unstable and is not used as a raw material. Natural yeast powder is mainly from Japan. import
However, imported natural yeast powder has the problems of high cost, untimely supply, and low yeast content. Natural yeast powder imported from Japan contains dozens of natural yeast counts in 1g, and its use is limited.
[0007] Yeast cells and cultures are generally cultured in a medium rich in phosphorus, nitrogen, and molasses, so yeast powder generally has the problems of short shelf life, mildew, and aging

Abstract

The invention discloses a preparation method for pure natural yellow koji yeast powder. The preparation method comprises the following steps: crushing grapes, broccolis, peaches, cherries, kiwi fruits, dragon fruits, strawberries, blueberries and figs and adding the crushed grapes, broccolis, peaches, cherries, kiwi fruits, dragon fruits, strawberries, blueberries and figs into water; adding saccharose, honey and maltodextrin; raising the temperature to 25-30 DEG C; adjusting the pH value to 3-5 and the humidity to 65-75%; placing for 7-10 days and filtering to obtain a yeast solution; adding rice flour, soybean meal and maltodextrin into water; kneading to yeast slurry with the pH value of 3-6; culturing the yeast slurry three times to obtain tertiary east slurry; mixing the third yeast mud with the fermented liquid, kneading the mixture for 20-30 minutes, standing the mixture for 5-8 hours at 5-15 DEG C and then enlarging cultivation to obtain a mixed yeast solution; and mixing the mixed yeast solution, glucose, alpha-dried rice flour, vitamin C, maize starch, saccharose, honey and xylitol and then drying, crushing and sieving the mixture to obtain the pure natural yellow koji yeast powder.

Description
