By-products of food processing operations may still contain valuable substances such as dietetic fiber, organic acids, pigments, and flavors. Drying these by-products and converting them into powder offers a way to preserve them as useful and valuable products. Food By-Product Based Powders as Functional Food Ingredients covers by-products derived from seafood, oil and fat, tea and herbal tea, milk and dairy products, fruits and vegetables, and meat and processed meat products. This reference book discusses the characterization, enhancing technologies, and processing of food by-product powders. It also addresses biological interactions, drug interactions, and pharmacological evaluations of food by-products.
