ONLINE RETORT CONTROL IN THERMAL STERILIZATION OF CANNED FOODS

This paper presents a short review of recent developments toward achie ving computer-based intelligent on-line control systems for assuring s afety, quality, and process efficiency of thermally processed canned f oods, Various approaches based upon real-time data acquisition systems are described along with alternative approaches based upon the use of calculated correction factors or mathematical models capable of simul ating the heat transfer into canned foods under various processing con ditions. The various features of each method are discussed along with suggested industry applications that would be appropriate for each met hod. (C) 1997 Elsevier Science Ltd.
