Applications of Recovered Bioactive Compounds in Food Products

This chapter focuses on the use of bioactive compounds derived from grape pomace to develop innovative products that provide a source of health-promoting and "clean label" ingredients. It covers the growing interest in replacement of synthetic additives by natural compounds, due to both legal restrictions and consumer demand for natural foods. Moreover, it discusses consumer demand for foods that can help prevent major chronic diseases, while contributing to sustainable use of natural resources. It reviews the multifunctional properties of ingredients derived from grape processing waste. These include their use as antioxidants, colorants, antimicrobials, texture-modifying agents, and fortifying ingredients. Successful food applications are illustrated, comprising examples in various sectors including meat, fish, cereal-based, dairy, and fruit-based products. Thorough information is provided on the type of recovered raw material (whole pomace, skins, or seeds), ingredient formulation (liquid/powder/encapsulated crude extract or purified extract, micronized fiber fraction), and typical levels used in foods. Moreover, the technological advancements made possible by the recovery of these ingredients and their reintroduction into the food chain are discussed.
