Process for producing a powdery fermented dairy product

摘要

The invention relates to the dairy industry, namely to a process for producing a powdery fermented dairy product.The process, according to the invention, involves inoculation of the lactic substrate with 5% starter culture at a concentration of 1010 cells/ml suspension, containing a mixture of a Streptococcus thermophilus strain producing exopolysaccharides with a strain non-producing exopolysaccharides Streptococcus thermophilus or Lactobacullus bulgaricus, followed by fermentation of the substrate at a temperature of 40…42°C to the pH of 4.7…4.6, freezing of the fermented dairy product to a temperature of minus 10…12°C inside the product mass and lyophilization for 20…22 hours, at a residual pressure of 57 Pa, to the attainment of a temperature of 24…26°C and milling of the finished product.
