METHOD FOR PREPARING OF SOUR MILK PRODUCTS, METHOD FOR TREATING OF MILK FOR EFFECTUATING THE SAME, SOUR MILK PRODUCT PREPARING LINE AND MILK TREATING APPARATUS FOR THE SAME LINE Russian patent published in 2006 - IPC A23C9/00 A23C9/12 A23C9/13 A23C9/133 A23C3/00 

FIELD: milk industry, in particular, production of pasteurized whole milk and sour milk products based thereon.

SUBSTANCE: method involves providing milk treatment process and subsequent operations in the presence of milk-soluble polyphosphoric acid derivative having general formulation of HO-[PO₃X]_n-PO₃X₂, where X are ions of sodium, potassium, calcium, magnesium, hydrogen or ammonium, 30≥n≥1, with quantitative value thereof of 0.4-0.7 g/l; processing milk by double pasteurization process; bottling; packing and pressurizing at temperature of 68-72 C before second pasteurization process; introducing starter into packed milk by providing ultraviolet radiation of starter introduction zone; providing final pressurization of package. Milk treatment method involves, after first pasteurization procedure, holding milk at temperature of 68-72 C for at least 15 min for potable milk and for at least 5 min for sour milk products; providing bottling and pressurization after first holding at holding temperature; cooling pressurized milk to temperature of 12-37 C and holding at such temperature for at least 30 min; providing second pasteurization process after said holding process by heating milk to temperature of 68-72 C at heating rate of at least 10 C/s. Also described are constructions of line for effectuating said method of producing sour milk products and apparatus for treating milk.

EFFECT: more thorough sterilization of milk and avoiding secondary seeding of products during production thereof at all the stages, improved organoleptical properties and prolonged shelf life of sour milk products.
