Abstract
A method of increasing the durability of fresh milk when filling the same into containers and packages, in which the fresh milk is pasteurized with a short-term preheating to approximately 100.degree. to 120.degree. C. for killing pathogenic germs and subsequently processed at 70.degree. to 80.degree. C. The thus treated milk is packaged at a temperature from 70.degree. to 80.degree. C. within an aseptic protective gas atmosphere into heat resistant, substantially gas-tight synthetic foil packages and immediately after closing of the packages the milk is cooled in several stages, first rapidly to 50.degree. to 60.degree. C. and thereafter to a predetermined storage temperature.
Claims6
A method of increasing the durability of fresh milk when filling the same into containers and packages, comprising the steps of:
- subjecting the fresh milk to pasteurization including a short-term preheating to approximately 100.degree. to 120.degree. C. for killing all pathogenic germs;
- cooling the milk to a filling temperature in the range of 70.degree. to 80.degree. C.;
- filling the thus treated milk at said filling temperature within an aseptic protective gas atmosphere into heat resistant, substantially gas-tight synthetic foil packages;
- closing said packages;
- and immediately thereafter cooling the milk in several stages, first rapidly to 50.degree. to 60.degree. C. and thereafter to a predetermined storage temperature, said steps of subjecting to pasteurization, cooling to the filling temperature, subsequent filling and closing, and reaching the first recooling stage of from 50.degree. to 60.degree. C., being carried out within a hot holding period of approximately 40 to 50 seconds.
A method of increasing the durability of fresh milk when filling the same into containers and packages, comprising the steps of:
- filling substantially bacteria free milk at a filling temperature from 70.degree. to 80.degree. C. within an aseptic protective gas atmosphere into heat resistant, substantially gas-tight synthetic foil packages;
- closing said packages;
- and immediately thereafter cooling the milk in several stages, first rapidly to 50.degree. to 60.degree. C. and thereafter to a predetermined storage temperature, said steps of filling and closing of the container until reaching the first recooling stage to 50.degree. to 60.degree. C., being carried out within a hot holding period of approximately 40 to 50 seconds.
