Strawberry-state probiotic yogurt production process

Abstract

The present invention provides a strawberry-taste probiotic yogurt production process, which comprises: collecting milk; carrying out a pretreatment; preparing materials; preheating; degassing; homogenizing; sterilizing; inoculating, wherein the strains comprise Bifidobacterium, Lactobacillus acidophilus and enterococci, the volume ratio of the three strains is 0.5:0.5:1.5, the inoculating amount is 3-4%, the inoculating temperature is 40-42 DEG C, and stirring is performed for 15-20 min after inoculating; fermenting, wherein the uniformly-mixed material is fermented for 4-6 h at a temperature of 40-42 DEG C, the acidity is controlled during the fermenting process, demulsification is performed after the fermenting achieves the end point acidity, and cooling is performed to achieve 18-24 DEG C; adding a strawberry jam; and filling, and carrying out cold preservation. The physical and chemical indicators of the strawberry-taste probiotic yogurt of the present invention are as the follows: the fat content is more than or equal to 2.5%, the protein content is more than or equal to 2.3%, the non-fat milk solid content is more than or equal to 6.5%, the acidity (DEG T) is 70-110 DEG T, the white granulated sugar content is more than or equal to 5.0%, the strawberry jam content is more than or equal to 10%, and the live flora of the probiotics is 106-108 CFU / ml.

Description

Technical field [0001] The present invention involves a strawberry taste probiotic yogurt production process. Background technique [0002] Probiotics, this concept first comes from Greek, means "beneficial to life".As early as ancient times, human daily diet had contained lactic acid fermented foods.The so -called probiotics are to reach the small intestine alive, and inhibit the reproduction of harmful bacteria in the intestine, promote intestinal movement, thereby improving the intestinal function and improving the beneficial bacteria of the bowel movement.Probiotics are friendly bacteria that are beneficial to health. They can enhance and maintain the natural balance of the intestine, and they are also very important balanced on the health and immune system. [0003] Hundreds of probiotic health products have been developed abroad, including: yogurt, sour cheese, yogurt milk, and oral liquid, tablets, capsules, powder, etc. containing a variety of probiotics, and so on.So far...

AI Technical Summary

Problems solved by technology

[0009] Yogurt has a short shelf life due to the presence of probiotics. It can be stored for up to 7 days at 4°C, and lactic acid bacteria still have fermentation power at this temperature. With the extension of storage time, the content of lactic acid bacteria decreases, which affects the health function of yogurt.
