Abstract:
The components of the freshwater mussel meat, mantle and mussel tears (humor) were determined, and nutritional qualities were synthetically evaluated.Results showed that the water contents of freshwater mussel meat, mantle and humor were 76.92%, 82.44%, 89.31%, respectively.The contents of crude protein were 51.07%, 47.72%, 43.84%.Contents of ash were 7.19%, 15.01%, 4.34%.Contents of crude fat were 7.45%, 6.37%, 4.57%.Contents of carbohydrate were 26.65%, 22.94%, 42.46%.The total amino acids of the freshwater mussel meal, mantle and humor, were 41.54%, 37.61%, 32.56% respectively, and the percentage of essential amino acids in total amino acids were 44.43%, 42.75%, 45.06%, respectively, which were close to the pattern of FAO/WHO.Minerals contents was rich such as Ca, Fe, Mg, especially the heavy metal in the mussel meal were all under the restriction of food safety.There were affluent contents of unsaturated oils, were 64.05%, 70.39%, 57.49%.As a conclusion, the freshwater mussel is precious and excellent source at every pore, which is low in price.
