摘要:
The present invention relates to a method of inactivation of plasmin enzyme in a milk-based product, wherein casein and whey protein are separated from a milk raw material by microfiltration to provide a casein concentrate as a microfiltration retentate having a whey protein content of less than 20 wt. %, based on the total protein content of the concentrate, and a whey protein concentrate as a microfiltration permeate; the casein concentrate is subjected to a thermal treatment at a temperature in the range of about 72° C. to about 95° C. to provide a thermally treated casein concentrate; and a milk-based product with a reduced plasmin activity comprising the thermally treated casein concentrate is provided. The milk-based products prepared by the method retain flawless organoleptic properties at different storage temperatures even under prolonged storage periods.

Disclosed are processes for producing cultured dairy products, such as yogurt, that are shelf-stable without refrigeration. Such processes can include contacting a milk base having from 0.5 to 1.9 wt. % milk sugar with a lactic acid bacteria culture and aseptically packaging in a container, followed by storage under conditions suitable to result in a pH of less than 4.7.

Carbon dioxide is dissolved in liquid dairy products loaded and transported in bulk containers so as to improve product shelf life, thereby providing options for more economical shipment, as by rail and ocean vessels and for extended transport by truck and to facilitate extended storage of perishable products and to avoid the necessity of multiple treatments for pathogen reduction.
摘要:
According to one embodiment of the present invention, a mixture including milk and one or more gas additives is received at a milk processing system. The system heats the mixture and directs it toward an inlet to be delivered into a vacuum chamber. The vacuum chamber applies a negative vacuum pressure to the mixture to substantially remove the added gas. The resulting milk is extracted from the vacuum chamber.

Methods for storing human breast milk, preserving its natural flavor and nutritional content. Through the use of an apparatus such as a breast pump, breast milk is expressed from a lactating woman. The milk is transferred through a fill line into a storage container. After the container is substantially filled with breast milk, the fill line is decoupled from the breast pump output, and a vacuum is applied to the line. After the remaining air is evacuated from the container, an isolation valve in the fill line is closed, sealing the container in an evacuated condition. The fill line is removed from the valve, and the container is placed into a freezer or refrigerator for storage. When ready for use, the container is removed from the freezer or refrigerator, the milk is thawed, and the vacuum is broken, allowing removal of the milk for transfer to a bottle.
摘要:
The present inventions belong to the milk industry and can be used for producing pasteurized whole or restored milk and sour milk products on their basis, with a long-term storage time and improved organoleptic characteristics. The inventions provide more careful sterilization of milk and elimination of secondary contamination of products during all production stages thereof. The inventions consist in the method for producing sour milk products consisting in carrying out a milk treatment process and subsequent operations in the presence of soluble in milk derivative of polyphosphoric acid 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 0.7 g/l; the milk treatment is carried out with double pasteurization, bottling and packing are associated with hermetic sealing at a temperature of 68-72° C. up to the second pasteurization, ferment is applied into hermetically sealed milk at ultraviolet irradiation of applying ferment area and is followed by the final hermetic sealing of a package afterwards. The invention also consists in the method of milk treating when after the first pasteurization the milk is kept at a temperature 68-72° C. for not less than 15 minutes for a drinking milk, and not less than 5 minutes for sour milk products, bottling with hermetic sealing is carried out after this keeping at the said temperature, then hermetically sealed milk is cooled down to a temperature of 12-37° C. and kept at this temperature for not less than 30 minutes, the second pasteurization is carried out after the said keeping by heating the milk to a temperature 68-72° C. at a heating rate equal to or greater than 10° C./sec. The inventions also consist in the structural design of the line for realization of the method of production of sour milk products, in the structural design of the device for milk treating for realization of the method of milk treating.
