CONCENTRATED LIQUID MILK PRODUCTS STABLE IN PROCESS OF STORAGE WITHOUT COOLING AND THEIR PRODUCTION METHODS Russian patent published in 2011 - IPC A23C9/14 A23C1/16 

FIELD: food industry.

SUBSTANCE: invention relates to dairy industry, in particular to stable concentrated liquid milk products and to their production method. The method includes no heat treatment before and during concentration which may essentially cause casein cross-linking with whey proteins; one preferably uses microfiltration (with diafiltration or without it) to produce a stable concentrated liquid milk product with reduced content of whey protein and lactose. The products finally produced have sterilisation index F₀, at least 5, the total content of dry substances being from nearly 25% to nearly 30%; the total content of protein is from nearly 9% to nearly 13% including at least nearly 90% of casein protein and less than nearly 10% of whey proteins and less than nearly 1% of lactose.

EFFECT: invention allows to produce a product resistant to jelling in the process of sterilisation and storage during a long period of time.
