Effervescent tablet starter and preparation method thereof

Abstract

The invention discloses an effervescent tablet starter and a preparation method thereof. The effervescent tablet starter comprises, by weight, 15-20 parts of zymocyte powder, 30-35 parts of tartaric acid, 20-25 parts of sodium bicarbonate, 5-10 parts of dextrin, 5-10 parts of lactose, 1-5 parts of mannitol, 1-5 parts of polyethylene glycol 6000 and 1-5 parts of aerosil. The preparation method comprises the following steps: inoculation and fermentation of multiple strains, and lyophilizing for preparing dry powder of fermented milk; and freeze-drying of all above components, crushing, and tableting for obtaining the effervescent tablet. The effervescent tablet starter is prepared by mixing the zymocyte powder, prepared from Streptococcus thermophilus, Lactobacillus bulgaricus, Bifidobacterium, Lactobacillus rhamnosus, Lactobacillus casei, Lactococcus Lactis subsp Lactis and Lactobacillus plantarum, with auxiliary materials which are an effervescent agent, a diluents and a lubricant. Theeffervescent tablet has the characteristics of multiple strains and high vitality, and yogurt prepared by using the effervescent tablet starter is similar to yogurt prepared by direct fermented milkin fermentation period, post-acidification, whey precipitation rate and mouthfeel.

Description

technical field [0001] The invention relates to the field of bioengineering, in particular to an effervescent tablet starter and a preparation method thereof. Background technique [0002] Due to its rich nutritional value and good health functions, the production and sales of fermented yogurt are growing rapidly. Because the direct-injection strain starter simplifies the process of strain activation and amplification, not only the dosage is small, the operation process is simple, the quality is easy to control, and it is not easy to be polluted by miscellaneous bacteria, but also ensures the quality and taste of the product during the subculture process. In 2002, the total output of fermented yogurt in my country was about 630,000 tons, of which 500,000 tons of yogurt used a direct-type starter, which cost about 80 million yuan a year to purchase. But the traditional yogurt starter is generally a powder, which generally needs to be stirred continuously for more than 10 min...
