Problems solved by technology

[0003] Private kitchen brushed yogurt is rich in exopolysaccharides (EPS), which can effectively inhibit inflammation, maintain intestinal barrier function, regulate intestinal flora, and fight cancer. The simple and natural features are in line with the current product trends. For example, the prior art discloses a yogurt with enhanced stringiness and its preparation method. However, Streptococcus thermophilus, Lactobacillus bulgaricus, acidophilus The five strains of Lactobacillus, Lactobacillus rhamnosus and Lactobacillus plantarum have complex ingredients. Therefore, it is urgent to develop a yogurt with simple ingredients and strong stringiness to meet the growing market demand for dairy products

Abstract

The invention provides a private drawing yoghurt and a preparation method thereof. The method comprises the following steps: firstly, filtering raw milk through an RO (Reverse Osmosis) membrane until the protein content of the raw milk is 4.0-4.8 wt%, sequentially homogenizing the obtained concentrated milk at 0-200bar, stirring, sterilizing, cooling, adding a leavening agent, fermenting until the pH value is 4.6-4.8, stirring and demulsifying at the rotating speed of 300-600rpm / min, and carrying out after-ripening for more than 12 hours, so as to obtain the wiredrawing yoghurt for the private cuisine, wherein the leavening agent is composed of streptococcus thermophilus and lactobacillus bulgaricus, and the dosage ratio of the streptococcus thermophilus to the lactobacillus bulgaricus is 1 * 10 < 11 > CFU: 2.1 * 10 < 7 >-5.2 * 10 < 7 > CFU. The yoghurt prepared by the preparation method disclosed by the invention not only has excellent tissue state, mouth feel, flavor and smell and relatively high exopolysaccharide content, but also has relatively strong wire drawing characteristic.
