Production process of passion fruit and water-chestnut flavored probiotic yoghourt

Abstract

The invention provides a production process of passion fruit and water-chestnut flavored probiotic yoghourt. The production process comprises the following steps: collecting milk; pretreating; preparing materials; preheating; degassing; homogenizing; sterilizing; inoculating, wherein strains comprise bifidobacterium, lactobacillus acidophilus and enterococcus in a volume ratio of 0.5 to 0.5 to 1.2, the inoculating amount is 3%-4% and the inoculating temperature is 40-42 DEG C; stirring for 15-20 minutes after inoculating; fermenting, namely fermenting the mixed materials at 40-42 DEG C for 4-6 hours; controlling the acidity in a fermenting process; carrying out emulsion breaking after the materials are fermented to the final acidity; cooling to 18-24 DEG C; adding passion fruit juice and water-chestnut juice; and filling and freezing. The passion fruit and water-chestnut flavored probiotic yoghourt provided by the invention has a unique flavor, is sour and sweet, and palatable, and also has a fresh mouth feel and a harmonious taste; and meanwhile, the passion fruit and water-chestnut flavored probiotic yoghourt has the health and nutritional functions of passion fruits and water-chestnuts, and has a good health effect.

Description

technical field [0001] The invention relates to a production process of probiotic yoghurt with passion fruit and water chestnut taste. Background technique [0002] The concept of probiotics originated from Greek, which means "good for life". As early as in ancient times, lactic acid fermented foods have been included in the daily diet of human beings. The so-called probiotics are beneficial bacteria that can reach the small intestine alive, inhibit the reproduction of harmful bacteria in the intestine, promote intestinal movement, thereby improving intestinal function and defecation. Probiotics are friendly, healthy bacteria that enhance and maintain the natural balance of the gut, a balance that is important for overall health and the immune system. [0003] Hundreds of probiotic health care products have been developed abroad, including: yogurt, yogurt, soy milk containing probiotics, and oral liquids, tablets, capsules, powders, etc. containing a variety of probiotics....

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.
