This webcast was organized with the support of IFT's Nonthermal Processing Division.
Consumer health and wellness oriented life style prompted food processors to introduce a variety of minimally processed extended shelf-life (ESL) foods. This webcast provides an overview of microbiological risks associated with preservation of ESL foods and presents various available minimal processing technological solutions. After watching this webcast, you will understand how food processing, ingredient, and storage factors that can help mitigate the pathogens risk in ESL products.
Extended Shelf Life (ESL) refers to foods that have received mild processing and have a shelf life under refrigerated storage that is greater than that afforded by minimal processes such as conventional pasteurization. The ESL product category has emerged to satisfy consumer demand for mildly-processed foods with enhanced safety, shelf-life, and fresh-like quality. Meat, seafood, vegetable and fruit juices, sauces, and salads are examples of products available in the market today. ESL products are preserved by variety of milder processing solutions including high pressure processing. While pressure treatment at ambient or chilled temperature is effective in reducing more than 5-logs of variety of vegetative pathogens, pressure treatment alone, is not sufficient to inactivate spores of harmful pathogens such as Clostridium botulinum. Careful attention must be paid in maintaining refrigerated temperature conditions handling and distributing ESL foods. The webcast speakers discuss potential microbial risks associated with survival of Clostridium spores in ESL low-acid foods. Food processing, ingredient, and storage factors that can help mitigate the botulinum risk are also discussed.
1. Learn about basic principles and technologies associated with manufacturing of extended shelf life products
2. Learn about processing and storage factors that can help mitigate botulism risk in low-acid foods preserved by pressure based technologies
3. Understand physiological mechanism of germination and inactivation of pathogenic spores
