Abstract: The present invention relates to an assembly that includes a ready-to-drink, long lasting, milk based beverage inside of a container. The beverage is under pressure and contains between about 0.5 and 5 g/l of nitrous oxide or carbon dioxide. The container has a head space of from about 9 to 15%, relative to the total volume of the said container. The said space is saturated with nitrogen so as to have a relative pressure of between 1.5 and 4 bar.

Abstract: A UHT-treated or sterilized or ultrapasteurized milk base product is obtained without the presence of thickening or gelling agents by adding calcium glycerophosphate and a calcium chelating agent to a milk base, the pH of the calcium-enriched milk base product is adjusted to a pH of between 6.6 to 7.2 and then the pH-adjusted product is subjected to UHT treatment and that product is packaged, or alternatively, calcium glycerophosphate and a chelating agent are added to water to obtain a mixture, the pH of the mixture is adjusted to a pH of between 6.6 to 7.2 to obtain a solution, the solution is heat-treated to sterilize it, and then the sterilized solution is metered into a milk base which has been sterilized or ultrapasteurized.
