METHOD FOR PRODUCING SOUR MILK PRODUCTS, METHOD FOR TREATING MILK THEREFOR, SOUR MILK PRODUCTION LINE, DEVICE FOR TREATING MILK FOR SAID LINE.

摘要

The inventions relate to the milk industry and can be used for producing pasteurised whole or reconstituted milk and sour milk products which are based thereon, have a long-term storage time and exhibit improved organoleptic characteristics. Said invention makes it possible to carry out a more careful milk sterilisation and to exclude the recontamination of products during all production stages thereof. The sense of the invention lies in a method for producing sour milk products consisting in carrying out a milk treatment process and subsequent operations in the presence of a milk-soluble polyphosphoric acid derivative of general formula HO-[PO3X]n-PO3X2, wherein X represents sodium, or potassium, or calcium, or magnesium, or hydrogen or ammonium ions and 30≥n≥1 at a quantitative value thereof ranging from 0.4 to 0.7g/l. The milk treatment is carried out by double pasteurisation, filling and packing are associated with sealing at a temperature of 68-72 °C up to the second pasteurisation, a starter is inoculated into packed milk at ultraviolet irradiation of the starter inoculation area and is followed by the final sealing of a package. The inventive method for milk treating consists, after a first pasteurisation, in holding the milk at a temperature of 68-72 °C at least for 15 minutes for a drinking milk and at least 5 minutes for sour milk products, in dispensing the milk under vacuum after holding at the temperature of said holding, afterwards, in cooling the sealingly packed milk to a temperature of 12-37 °C and in holding at said temperature at least 30 minutes. The second pasteurisation is carried out after the holding by heating the milk to a temperature of 68-72 °C at a heating rate equal to or greater than 10 °C/sec. The structural design of a production line for carrying out the method for the production of sour milk products and a device for treating milk used for carrying out the milk treating method are also disclosed.
