Processing Effects for Safety and Quality in Some Non-Predominant Food Technologies

Abstract

Food functionality can be related to nutrient and non-nutrient compounds. Some foods are fortified with various nutrients whereas others are manipulated using their physicochemical properties in order to make them “functional.” Texture, color, taste, odor, and other physicochemical properties may affect the overall quality and, hence, acceptance of food products. Since food safety is also an important factor to be considered in food processing, preservation methods are selected taking into account the best compromise between microbial inactivation and preservation of quality attributes. Instrumental and sensory methods, as well as a match between them, are studied and perfected in order to verify how well a specific type of food has been processed to make it “functional” in sensory terms.
