ABSTRACT
This chapter discusses food powders derived from food by products and wastes, as well as their chemical, functional properties, bioactive features, and utilizations. Food by-products or food industry shelf-stable coproducts such as liquid, pomace, or powder forms can be obtained by processing fruits, vegetables, meats, seafoods, milk and dairy, cereals, nuts, and fats and oils. The health benefits of fruits and vegetables are primarily attributed to bioactive nutrients such as phytochemicals, carotenoids, and vitamins, as well as to the dietary fiber they contain. The by-products of fruits and vegetables are sources of highly desirable healthy compounds, which are considered highly desirable. The chapter shows the powder obtained as a by-product of pear peel. Meat by-products are produced by slaughterhouses, meat processors, wholesalers, and rendering plants. Seafood by-products are good sources of antimicrobial compounds and seafood-derived peptides are multifunctional ingredients. Shrimp cooking wastewater is also a good source of astaxanthin and bioactive peptides.
