Nghiên cứu thành phần lý-hóa hải sâm cát (<i>Holothuria Scabra</i>) nguyên liệu nuôi tại vùng biển Ninh Hòa, Khánh Hòa

Abstract

The study evaluated several physicochemical composition on three size groups of sandfish (Holothuria scabra) 5-6 individuals/kg (small group), 3-4 individuals/kg (medium group) and 1-2 individuals/kg (large group), purchased from farming ponds in the Ninh Hoa sea area, Khanh Hoa. Results showed clear differences among the groups, specifically: Regarding the proportion of edible (meat), the small and medium groups had a lower than the large group by 8-10%; Regarding water content, the large group had the lowest water content (77.01%), nearly 6.5% lower than the small group and nearly 1.0% lower than the medium group. The medium group’s water content (78.91%) was almost 5.0% lower than the small group; For the indicators protein, lipid, carbohydrate, calcium, phosphorus, and total ash across the different sandfish groups, there were varying increases and decreases. Protein ranged from 61.60% to 74.34%, lipids from 3.16% to 5.89%, carbohydrates from 7.29% to 8.20%, calcium from 0.74% to 1.07%, phosphorus from 0.18% to 0.49%, while total ash decreased from 27.64% to 10.00%. Therefore, harvesting, processing, and using sandfish raw material from the larger-weight group will help improve meat recovery efficiency and increase the nutritional, mineral when using the same amount of raw material.
