Woodhead Publishing Maximising the Value of Marine By-products (Woodhead Publishing Series in Food Science, Technology and Nutrition)

Over-exploitation and declining fish stocks are creating an urgent need for better utilisation of seafood by-products. Currently a large proportion of the catch is wasted, even though marine by-products contain valuable protein and lipid fractions, vitamins, minerals and other bioactive compounds beneficial to human health. This book covers marine by-product characterisation, recovery, processing techniques, food and non-food applications: essential information for those involved in seafood by-product valorisation. Key Features: learn how to devise strategies for the full utilisation of the catch; understand the importance of marine by-products to human health; explores the use of marine by-products in diverse areas such as agriculture, medicine and energy production. Contents: Part 1 Marine by-products characterisation, recovery and processing: Physical and chemical properties of protein by-products from seafood waste; Physical and chemical properties of lipid by-products; On-board handling of marine by-products to prevent microbial spoilage, enzymatic reactions and lipid oxidation; Recovery of by-products from seafood processing streams; Increasing processed flesh yield by recovery from marine by-products; Enzymatic methods for marine by-products recovery; Chemical processing methods for protein recovery from marine by-products and underutilized fish species. Part 2 Food uses of marine by-products: By-catch, underutilized species and underutilized fish parts as food ingredients; Mince from seafood processing waste and surimi as food ingredients; Aquatic food protein hydrolysates; Functional properties of protein powders from underutilized marine fish and seafood products; Marine oils from seafood waste; Collagen and gelatine from marine by-products; Seafood flavour from processing by-products; Fish and bone as a calcium source; Chitin and Chitosan from marine by-products; Marine enzymes from seafood by-products; Antioxidants from marine by-products; Pigments from by-products of seafood processing. Part 3 Non-food uses of marine by-products: By-products from seafood processing for agriculture and animal feeds; Using marine by-products in pharmaceutical, medical and cosmetic products; Bio-diesel and bio-gas production from seafood processing by-products; Composting of seafood wastes.
