Review: Flame sterilization

Abstract

SummaryFlame sterilization is a technique of high temperature, short time processing that is applied to sealed metal cans. The technique is applicable to the processing of both high and low acid products and may be used to exhaust packs to produce a high vacuum when subsequently cooled. The factors affecting the rate of heat transfer and their influence on container requirements and product quality are discussed, together with commercial developments and prospects for flame sterilization processes.
