Embodiment Construction

[0021] The concrete implementation method of present embodiment is, at first will make standardized milk, and its concrete process is as follows:

[0022] A Milk cleaning and cooling: Use milk that complies with NY / T 1172-2006 raw milk quality management as raw milk, pass through a filter and a milk cleaning machine to clean the milk, and then cool to 2-6°C, and the storage time should be less than 24 hours;

[0023] B Standardization: The raw milk is concentrated and fat-removed through evaporators and separators, so that the protein content in it is not less than 3.1%, and the fat content is not more than 1.25%;

[0024] C Homogenization and sterilization: two-stage homogenization is adopted, the total pressure is kept at 170-180Bar, until the fat in the raw milk is refined, after homogenization, the raw material is heated to 85-90°C through a heat exchanger, and kept for 15s, and then used in ingredients;

[0025] D Storage: If the raw milk obtained in step C is not used f...

Abstract

The invention belongs to the field of milk products and particularly relates to a processing process of low-fat yoghourt. The processing process comprises the following steps of adding 400L of standard milk into a batching tank, raising the temperature to 60-70 DEG C, adding white granulated sugar, a stabilizing agent, inulin and polydextrose, stirring and cooling; then adding a cooled mixture from the former step into a constant-volume cylinder, adding about 400L of standard milk and yoghourt essence and cream essence, then stirring uniformly, adding pure water to be 1000L, then homogenizing and sterilizing by a pasteurization unit, then reducing the temperature to 43-45 DEG C, pumping a mixture from the former step into a fermentation tank, adding strains, and uniformly standing for fermentation; and after fermentation is finished, overturning the cylinder, cooling, reducing the temperature to about 25 DEG C, and filling. The processing process adopting the technical scheme has the advantages that the method is simple and feasible and is suitable for large-scale production, and the formed product is low in fat content, unique in taste and fine and smooth in quality.

Description

technical field [0001] The invention belongs to the field of dairy products, and in particular relates to a low-fat yoghurt processing technology. Background technique [0002] Dairy products are a healthy food with high nutritional value, rich in protein, fat, sugar, salt, lecithin, lactose, vitamin A, vitamin C, B vitamins, calcium, phosphorus, potassium, magnesium and All the amino acids needed for human growth and development. It can calm the nerves, beautify the skin, help lose weight, promote the development of children's brains, strengthen the strength of bones and teeth, help improve vision, promote the absorption of calcium and iron, enhance gastrointestinal motility, and help excrete milk protein for easy digestion and absorption . However, the fat content in dairy products is usually high. Studies have shown that excessive fat intake can cause obesity, hyperlipidemia, heart disease, arteriosclerosis, diabetes, gallstones and other health problems. Many consumer...
