A METHOD OF PREPARING A STABLE ALCOHOLIC BEVERAGE, ON THE BASIS OF SOURED MILK, HAVING GOOD KEEPING CHARACTERISTICS

摘要

A method of preparing a stable alcoholic beverage on the basis of soured milk and having good keeping characteristics. Milk or milk enriched with fat, with a fat content of at least 4% is mixed and homogenized, then eventually heat treated, rehomogenized and pasteurized before being soured by fermentation in known manner or by addition of a solution of an edible acid at a temperature below 5 DEG C to a desired pH value. The resulting product is mixed, if desired, with water or a water-containing liquid and optionally with sugars, fruit juice, fruit concentrate, fruit essence, flavouring agents, colouring agents and/or thickening agents. The mixture is then homogenized in two stages, one at a pressure of between 180 and 250 bar and one at a pressure of between 10 and 80 bar. The mixture is sublected to a thermal treatment in which it is warmed-up to a temperature of between 45 DEG and 55 DEG C, while keeping the mass in motion and maintaining a temperature difference between the mass and a heating medium of no more than 10 DEG C, and then cooled to a temperature of between 25 DEG and 35 DEG C, at which temperature the mixture is re-homogenized. The mass is then subjected to a thermal treatment to thermize, pasteurize or sterilize the product. Carefully deaerated alcohol is added to the stable soured product, while the mass is kept in rapid motion, optionally in combination with, or followed by the addition of flavour components. The pH of the liquid is adjusted to the value desired for the end product. Eventually the produce is pasteurized or sterilized.
