The Microbiological Safety of Low Water Activity Foods and Spices

Part of the book series: Food Microbiology and Food Safety ((PRACT))

Abstract

There is an increasing recognition of low-water activity foods as vectors for human pathogens. Partially or fully dried agricultural commodities, along with modern formulated dried food products, are complex and designed to meet a variety of nutritional, sensory, and market-oriented goals. This complexity means that advanced processing and treatment technologies are needed to achieve food standards. In this chapter, alternative energy-based antimicrobial processing interventions for low-water activity foods will be addressed, including advanced microwave processing, irradiation, and cold plasma. A discussion of existing commercial implementation for established technologies will provide a framework for examination of those recently emerging processes.
