Method for preparing high-calcium active lactobacillus beverage by fermenting broken rice and eggshell
Technical Field
The invention relates to a method for preparing a high-calcium active lactobacillus beverage by fermenting broken rice and eggshells, belonging to the fields of bioengineering technology and functional food.
Background
Brief introduction of lactic acid bacteria beverage:
the active lactobacillus beverage as a novel fermented milk beverage is rich in nutrition, has various health care functions of tonifying qi, invigorating spleen, improving human immunity and the like, and is high in digestibility, so that the active lactobacillus beverage is deeply loved by consumers. At present, the processing technology of the active lactobacillus beverage is not completely mature, the problems of serious post acidification, low active lactobacillus quantity, single fermentation nutrient source and the like of the product in shelf life influence the application and popularization of the lactobacillus beverage product.
The lactic acid bacteria beverage has the function of supplementing calcium lactate:
the current situation of insufficient calcium nutrition generally exists among consumers in China, particularly among children and the middle-aged and the elderly with poor gastrointestinal functions. The calcium element is added into the lactobacillus beverage, so that the supplement of the calcium element can be effectively improved, various health problems caused by the lack of the calcium element can be reduced, and the nutritive value of the lactobacillus beverage can be further improved. At present, the preparation method of calcium lactate generally comprises a chemical neutralization method and a microbial fermentation method, wherein the neutralization method is to add calcium hydroxide or calcium oxide into the finished lactic acid solution for neutralization reaction, and the finished product is prepared by processes of filtering, cooling crystallization, separation, drying and the like, so that the cost is high.
By utilizing the nutritive value of the eggshells and broken rice, the high-value utilization of waste resources can be realized:
300 ten thousand tons of eggshells are produced every year in China, most of the eggshells are discarded, and the problems of serious resource waste and environmental pollution are caused. The eggshell is rich in natural calcium, mainly contains calcium carbonate, and the content is about 85% -95%, which is a safe biological calcium, in recent years, researchers mainly aim to convert calcium carbonate in the eggshell into easily digestible and absorbable biological active calcium by means of biological fermentation, such as: calcium lactate, calcium citrate, calcium acetate, calcium propionate, and the like. The experiment research at home and abroad shows that the calcium lactate fermented by the eggshell is more effective in improving bone metabolism and preventing and treating osteoporosis than the calcium carbonate prepared by the traditional method.
The annual rice yield of China reaches 1.8-2.0 hundred million tons, which accounts for about 45% of the world yield, but the rice is limited to the existing rice milling technology, and 15% -20% of broken rice can be generated in the processing process. The broken rice contains about 75% of starch and about 8% of protein by mass, and compared with the whole rice, the broken rice contains more embryos which contain rich protein, fat, vitamins, mineral substances and other components, is rich in nutrition, and is a good resource with extremely rich value-added potential. The application of the broken rice in the production of the lactobacillus fermented beverage can improve the application output value of the broken rice and realize that the nutrition is easier to absorb.
The development of the functional lactobacillus beverage by jointly fermenting the eggshells and the broken rice is not reported.
