- 1. Technical requirements and ratio of raw materials:
Review on 1000L yogurt production lineRaw milk: It is fresh high-quality milk. It must not contain antibiotics or preservatives and other harmful bacteria. It is best to have a fat content of about 315%, a non-fat milk solid content of about 817%, a protein content of about 313% to 318%. Fetal and colostrum must not be used below 18 T. Granulated sugar: dry, white and shiny, no agglomeration, sweet and pure, no odor, no inclusions are allowed, and the ratio of fresh milk to sugar is 100: 10. The method of adding sugar is generally adding sugar to a small amount of raw milk, heating, dissolving and filtering, then pouring into the raw milk and mixing uniformly.
2. Heat treatment of milk:
In order to kill the bacteria in the milk and facilitate the reproduction of lactic acid bacteria, it is required to use a sterilization method at 85-90 C for 30 minutes, or an ultra-high temperature instant sterilization method at 135 C and 2s, and excessive heat treatment will destroy vitamins and beneficial bacteria. Growing substances that affect the flavor of the product.
The raw milk should be cooled immediately after sterilization, and the temperature should be the optimal temperature of the bacteria. about.
This process is absolutely critical, requiring workers, tools and equipment to be aseptic and to prevent pollution. Before the starter is added, its vitality must be measured. When the vitality is about 0.14, it can be added in an amount of 5%. When it is higher or lower than 0.14, it can be increased or decreased appropriately. After addition, it must be stirred evenly. Generally mixed strains are better than single strains. Generally, Bacillus can decompose part of casein and provide nitrogen source for cocci to promote the growth of cocci. Cocci can produce formic acid during milk fermentation to promote the growth and development of bacillus. Therefore, the use of mixed strains can speed up the coagulation of milk. Generally bulgaricus: Streptoc
