Edible viscera (EV) and remainder tissues (RTs) are two by-products of Chinese mitten crab. The objective of this study was to assess the nutrient and non-volatile taste compound contents of EV and RTs. EV and RTs were high in fat (25.35?%) and protein (16.46?%), respectively. Both by-products were good sources of Zn, Fe, and Cu. Both samples contained unsaturated fatty acids (75?% of the total fatty acids) and a balanced ratio of essential fatty acids. The total amino acid content relative to protein in EV and RTs were 77.62 and 66.74?g/100?g, respectively. Alanine (sweet), glutamate (umami), and arginine (bitter/sweet) were the predominant free amino acids that contributed to pleasant flavors due to their taste activity values (TAVs)?>1. TAVs of disodium 5-adenosine monophosphate, disodium 5-guanosine monophosphate, and disodium 5-inosine monophosphate were?>1 in RT but?
