Problems solved by technology

Some of the proteins contained in whey, such as immunoglobulins, are heat-sensitive and are easily lost when heated. The traditional whey beverage processing method uses whey powder or the remaining whey from making cheese as raw materials. Relatively strong heat treatment or acidification treatment, high-intensity heat treatment was carried out again in the subsequent whey beverage production process, and even a second high-temperature sterilization was carried out, which caused great damage to the original heat-sensitive protein of whey. Loss, the loss rate is about 40%-90%

Abstract

A method for producing whey beverages mainly includes: A, checking raw whey; B, purifying the raw whey; C, using an ultrafiltration membrane to filter the raw whey purified in the step B to obtain whey; D, adding lactose hydrolase into the whey obtained in the step C for hydrolysis; E, subjecting part of the whey hydrolyzed in the step D to membrane filtration and bacteria removal; F, adding ingredients into part of the whey, which is hydrolyzed in the step D but not subjected to membrane filtration and bacteria removal in the step D; G, sterilizing the whey processed in the step F at a high temperature prior to cooling; and H, mixing liquor obtained in the step E and liquor obtained in the step G. The content of heat-sensitive substances in the whey beverages produced by the method is high in retention rate, and the yield is increased.

Description

technical field [0001] The invention relates to a method for producing whey beverage, in particular to a method for producing whey beverage by using membrane filtration to process raw milk. Background technique [0002] Whey contains useful substances such as protein, carbohydrates, inorganic salts, and vitamins. Whey protein has certain medicinal properties and can be used in food and beverages after pretreatment. Some of the proteins contained in whey, such as immunoglobulins, are heat-sensitive and are easily lost when heated. The traditional whey beverage processing method uses whey powder or the remaining whey from making cheese as raw materials. Relatively strong heat treatment or acidification treatment, high-intensity heat treatment was carried out again in the subsequent whey beverage production process, and even a second high-temperature sterilization was carried out, which caused great damage to the original heat-sensitive protein of whey. Loss, the loss rate is...
