The Aquatic Product Processing and By-product Utilization

Book excerpt: Aquatic products are extremely popular with consumers since they have a unique taste and multiple bioactive substances such as protein, mineral elements, polysaccharides, and unsaturated fatty acids. However, the processing of aquatic products is still mostly at the primary processing level, resulting in a low utilization rate. Meanwhile, food processing causes a sizable number of by-products, seriously depleting natural resources and polluting the environment. Therefore, in-depth processing of aquatic products and the improvement of the comprehensive utilization of by-products are conducive to the high-value utilization of low-value aquatic products so as to maximize the development of aquatic resources, achieve sustainable development of resources, and ultimately obtain higher economic, ecological, and social benefits.
