Foods 2014, 3 305 1. Introduction Thermal processing is a widely used and extensively studied method for food preservation. Undesirable quality degradation that inevitably accompanies the targeted destruction of pathogens and
- Thermal process calculations refer to the design and/or the evaluation of a thermal process in terms of its ability to extend the shelf life of a product by destroying undesirable agents present in the food while preserving the quality characteristics of the product.
- thermal processing of low acid hermeticallysealed foods is conducted in accordance with a validated thermal process calculated by a person who has completed the ‘Approved Persons Course for the Thermal Processing of Low Acid Foods’ or equivalent and is appropriately qualified
- determination coefficient R2=0.991, better than ANN models. The mathematical procedure, quickly usable also with a spreadsheet, replaces the 57 Stumbo’s tables and 18512 data sets in the Ball formula method. Keywords: Mathematical modeling, Thermal process check, Canned food, Food engineering 1. Introduction Among the various methods for lengthening the food shelf life, the canned food is
