Abstract

The invention relates to a preparation method of konjac glucomannan compound health-care yoghurt, which comprises ingredients mixing, homogenization, sterilization, inoculation, fermentation and refrigerated ripening. The present invention uses konjac glucomannan and bifidobacteria as main raw materials. Konjac glucomannan is cheap and rich in sources, and can effectively promote the growth of bifidobacteria; bifidobacteria can produce lactic acid and Acetic acid can improve the utilization rate of calcium, phosphorus and iron. Bifidobacteria can produce essential nutrients such as vitamins B1, B2, B6, B12, alanine, valine, aspartic acid and threonine, which have important nutritional effects on the human body that cannot be ignored. The product produced by the method of the invention not only has the health care functions of cleaning stomach, preventing and treating obesity, lowering cholesterol and preventing and controlling hypertension, but also greatly reduces production cost and has broad market development prospect.
