[Ultra-flash sterilization of fluid food by friction]
Abstract:
The ATAD process without heat exchange nor steam mixing allows the sterilization in a very short time. With milk, the sterility has been attained regularly at 140 degrees C/0,54 seconds. Only small changes occurred in nitrogen distribution. An homogeneizing effect upon fat emulsion is noticeable. The amino-acid composition of isoelectric fraction is not that of casein owing to the coprecipitation of a part of whey protein at pH 4,6, but they do not reveal any degradation. The enzymatic digestion of proteins (pepsin + Pancreatin) is a little improved by this treatment; the availability of lysine, measured by dinitrophenylation or guanidination, is hardly modified. All the blocked forms of lysine (Maillard reaction, lysino-alanine reaction, peptidoïd boundings) occurs only under more drastic conditions. The beta-lactoglobulin-kappa-casein complex formation slightly hampers the enzymatic clotting of sterilized milk. The forms of calcium are not seriously disturbed and such a milk is suitable for cheesemaking; we can obtain cheese with very few non-lactic bacteria.

Cleaning, Sterilization, and Disinfection
Cleaning
The cleaning process usually involves using water with detergents or enzymatic cleaner and removing foreign material from objects and surfaces, including organic material such as body fluids or inorganic material like soil. Cleaning is performed before high-level disinfection and sterilization because foreign materials on the cover of the devices interfere with process...
Methods of Sterilization I: Physical Methods
Steam sterilization uses non-toxic, low-cost moist heat in the form of saturated steam under pressure, which is fast, microbicidal, and sporicidal, and quickly warms and penetrates fabrics. Autoclaves, or steam sterilizers, expose each item to direct steam contact for a predetermined time at the necessary...
