Study on the physicochemical composition of farmed sandfish (Holothuria Scabra) from the coastal waters of Ninh Hoa, Khanh Hoa
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.
