Les guides techniques EHEDG en Anglais

Thermal sterilisation is a process aimed at eliminating the risk of food poisoning and, when used in conjunction with aseptic filling, it aims to extend product storage life under ambient conditions. This is achieved by the destruction of vegetative micro-organisms and relevant bacterial spores. Earlier papers presented guidelines on continuous pasteurisation (Doc 1) and sterilisation (Doc 6) of liquid products without particles.

This paper presents guidelines on the design of continuous and semi-continuous plants for the heat treatment of particulate foods. Liquid foods containing particulates are inherently more difficult to process than homogenous liquids due to heat transfer limitations in particulate-liquid mixtures and the additional problems of transport and handling.

Although this document concentrates on sterilisation processes, the principles are consistent with other heat treatment processes. Ohmic heating techniques are not covered.
