Comparative Analysis of Nutritional Components of Wild Sea Cucumbers in Different Sea Areas

In order to provide reference for the comprehensive development and utilization, the nutritional function components of wild sea cucumbers in different sea areas were explored. This study comprehensively analyzed the nutritional composition of four wild sea cucumber species: Stichopus horrens, Stichopus chloronotus, Holothuria mammata, and Cucumaria frondosa. The basic nutritional composition, amino acid, fatty acid, and mineral element contents of the four sea cucumbers species were analyzed and evaluated. The results showed that the four species had high protein and low fat in common. Holothuria mammata exhibited the highest protein and lowest fat content. Stichopus chloronotus was rich in polysaccharides and ash content, while Cucumaria frondosa had notable saponin content. Each of the four sea cucumber types contained a consistent array of 17 amino acids, boasting substantial quantities of both delectable and medicinal amino acids. The essential amino acids accounted for a range of 13.78% to 20.27%, with
