Problems solved by technology

[0006] 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
[0007] Moreover, Pan

Example Embodiment

[0028] The method for preparing pure natural yeast powder of the present invention firstly prepares yeast liquid and yeast puree separately, then mixes this yeast liquid and this yeast puree together to cultivate yeast, and then expands and cultivates this yeast to prepare yeast powder, wherein :

[0029] Yeast preparation: 50-2000 parts by weight of fruits, grains or plant flowers are dipped with 50-3000 parts by weight of honey, 20-200 parts by weight of malt extract, and 100-2000 parts by weight at a temperature of 25°C to 35°C The mixed liquid phase of purified water is mixed and placed at a temperature of 20°C to 35°C, a pH of 2 to 5, and a humidity of 10% to 90% for 3 to 8 days, then 170 to 5200 parts by weight are extracted from it Fruit yeast liquid, grain yeast liquid or plant flower yeast liquid, the fruit yeast liquid, grain yeast liquid or plant flower yeast liquid contains the saccharomyces cerevisiae group of budding yeast and the lactic acid group of splitting yeas...

[0052] Example one

[0053] Yeast preparation: 1200 parts by weight of fruits, grains or plant flowers are mixed with 2200 parts by weight of honey, 120 parts by weight of malt extract, and 1200 parts by weight of purified water at a temperature of 25°C to 35°C. Under the temperature condition of 20℃~35℃, the pH value is 2~5, and the humidity is 80%, after standing for 6 days, 3520 parts by weight of fruit yeast, grain yeast or plant flower yeast are extracted from the fruit. Yeast liquid, grain yeast liquid or plant flower yeast liquid contains Saccharomyces cerevisiae group of budding yeast and lactic acid group of splitting yeast;

[0054] To prepare yeast paste: follow the steps below to incubate four times,

[0055] Cultivation for the first time: 300 parts by weight of rye flour, 40 parts by weight of malt extract, and 200 parts by weight of purified water with a temperature of 35°C to 70°C are kneaded together to form 540 weight with a pH of 3 to 6 Portions of yeast paste, c...

Abstract

The invention discloses a preparation method for purely-natural yeast powder. The preparation method for purely-natural yeast powder comprises the following steps of: preparing yeast solution, specifically, soaking fruits, grains or plant flowers in honey, malt extract and purified water, standing, and then extracting the yeast solution of fruits, grains or plant flowers, which contains a saccharomyces cerevisiae group and a lactobacillus group; preparing yeast paste, specifically, kneading naked barley powder, malt extract and purified water into the yeast paste, and culturing in four phases; culturing saccharomycetes, specifically, synthesising the yeast solution and the yeast paste into a wet cenobium, and culturing; performing enlargement culture on saccharomycetes, specifically, mixing the wet cenobium with an enlargement culture medium in a certain ratio, and performing enlargement culture on saccharomycetes by proliferating by 100-10000 times, so as to prepare mixed yeast solution; and blending the yeast powder, specifically, mixing the dry substances of glucose, alpha-dry rice meal, vitamin C, corn starch, cane sugar and the like in the mixed yeast solution, and finally preparing the natural yeast powder. The yeast powder disclosed by the invention is completely prepared from natural substances and free from preservative, and has the advantages of being anti-ageing, anti-mildew and long in storage life.

Description

[0001] The application of the present invention is a divisional application with an application date of March 31, 2012, an application number of CN201210092034.9, and an invention title of "Pure Natural Yeast Powder and Its Preparation Method". technical field [0002] The invention relates to a pure natural yeast powder, in particular to a pure natural yeast powder and a preparation method thereof. technical background [0003] The mainstream of yeast in the world today is dry yeast, which is very convenient to use because it is not limited by time, space and temperature. Dry yeast is a single yeast cultivated in the laboratory. It has strong fermentation power, is easy to store, and is convenient to transport and use. However, dry yeast has a smell that needs to be covered by other ingredients. Generally, butter, eggs or essence are used to cover the smell of dry yeast, and the bread made by dry yeast will become dry and hard after being stored for a long time, so often A...
