DRY CHEESE OR DAIRY FOOD PRODUCT OF SNACK TYPE AND METHOD FOR PRODUCTION THEREOF Russian patent published in 2019 - IPC A23C19/00 A23C9/00 

FIELD: dairy industry.

SUBSTANCE: group of inventions relates to dairy industry. To obtain a cheese or dairy product, the method is as follows. Specified cheese or milk mixture with a fat content less than or equal to 40 % by weight is prepared in the form of slices having a thickness less than or equal to 4 mm. Cheese or milk mixture is frozen to a temperature below or equal to -20 °C. Treatment is carried out with a reduced pressure of from 0.1 to 100 mbar to said frozen cheese or said frozen milk mixture. Heat the specified cheese or milk mixture under reduced pressure in one or two stages. First stage involves a rapid increase in the temperature of the specified cheese or milk mixture to a temperature of about 110–120 °C within 0.2 to 2 h at a pressure of from 0.1 to 100 mbar and at a flow rate of extraction steam from 0.4 to 10 kg of water per kg of product per hour. Second stage involves cooking at a temperature of from 60 to 160 °C at a pressure of from 0.1 to 100 mbar for 5 to 60 minutes. Cooled under vacuum at a pressure of from 0.1 to 100 mbar to a temperature ranging from ambient temperature (15–20 °C) up to 80 °C with a rate of temperature reduction in the range from 50 to 70 °C per hour. Increase the pressure by vacuum compensation with dry gas having a moisture content of less than 3 ppm.

EFFECT: group of inventions provides a product in the form of a foamed dry product of a hollow form with a crunchy texture, the product surface is uniform and smooth, the product has a cheese taste, retains a crunchy texture and the desired effect in the mouth, has low water activity relation to the original product.
