The shell is nearly spherical, and the spiral layer is about 6 layers. The spiral part is high, accounting for about 1/3 of the shell height. The body spiral layer is relatively expanded, smooth and rib free, with fine growth lines. The average meat content of the whelk was (75.40 ± 2.31)% (n=25), and the contents of protein, fat and carbohydrate accounted for (75.08 ± 1.51)%, (3.35 ± 0.24)% and (5.48 ± 0.23)% of the dry weight, respectively; A total of 17 kinds of amino acids were detected. The total content of amino acids in the dry sample was 57.46%, the content of essential amino acids was 21.32%, the total amount of flavor amino acids was 29.1%, and the essential amino acid index was 50.67; A total of 13 fatty acids were detected. The relative total amount of saturated fatty acids in the dry sample was 44.64%, monounsaturated fatty acids 25.17%, polyunsaturated fatty acids 29.93%, DHA and EPA 9.52%. Therefore, it is a seafood treasure with high protein and low fat, and has broad prospects for development and utilization.
