Automatically-fermenting active lactic acid bacteria and preparation method thereof

Abstract

The invention provides automatically-fermenting active lactic acid bacteria and a preparation method thereof, belonging to the technical field of lactic acid bacteria fermentation. The automatically-fermenting active lactic acid bacteria provided by the invention are prepared from the following raw materials: milk, corn, citric acid, a lactic acid bacterium starter, sorbitan oleate, a stabilizingagent, white granulated sugar and deionized water. Through addition of the lactic acid bacterium starter and the sorbitan oleate into the raw materials of the automatically-fermenting active lactic acid bacteria provided by the invention and cooperation of the raw materials, the survival period of lactic acid bacteria in beverage and the like prepared from the lactic acid bacteria can reach 2 to 3months under the condition of a normal temperature; meanwhile, the lactic acid bacteria are free of artificially-synthesized essence, pigments and chemical preservatives, are purely-natural active lactic acid bacteria, can be used for fermenting beverages, foods and the like, have good effects on human health, and have the physiological functions of helping digestion, improving the micro-ecological environment of intestinal tracts, inhibiting the growth of putrefaction bacteria, synthesizing nutrients, improving immune functions, etc.

Description

technical field [0001] The invention relates to the technical field of lactic acid bacteria fermentation, in particular to an automatically fermented active lactic acid bacteria and a preparation method thereof. Background technique [0002] Lactic acid bacteria and their fermented products have good effects on human health. It has physiological effects such as helping digestion, improving intestinal micro-ecological environment, inhibiting the growth of spoilage bacteria, synthesizing nutrients, and improving immunity. [0003] The cultivation of lactic acid bacteria is carried out in various ways. In order to produce lactic acid bacteria preparations or produce fermented milk, lactic acid bacteria beverages, cheese, etc., animal milk is used as a medium to cultivate lactic acid bacteria in most cases. However, since lactic acid bacteria generally have different nutritional requirements due to their different types, they do not proliferate very much in a culture medium con...

AI Technical Summary

Problems solved by technology

However, since long-term cultivation of lactic acid bacteria will lead to a decrease in the number of viable bacteria, it is not an ideal method for the production of lactic acid bacteria beverages or fermented milk that value the number of viable bacteria (the number of viable bacteria will reflect various physiological effects).

In addition, in the manufacture of beverages and foods such as lactic acid bacteria fermented products or fermented milk foods containing the fermented products, conventionally known substances added to promote the growth of lactic acid bacteria or to improve the presence of lactic acid bacteria are used in many cases. Active and mixed substances to obtain sufficient effect, the more these substances are used, the more they will affect the taste of the product, and this use will also lead to an increase in the cost of the product

Furthermore, in some cases, even if the state containing a large amount of live lactic acid bacteria can be maintained, the activity of lactic acid bacteria cannot be maintained, and sufficient physiological effects cannot be expected
