KARAKTERISASI KIMIA DAN SENYAWA BIOAKTIF KEONG TEMBERUNGUN REBUS (T. Telescopium) DARI PERAIRAN KOTA TARAKAN
Tarakan is a city that has a large enough fishery potential to be developed, one of which is useful and abundant but underutilized marine organisms, namely types of snails. This study aims to characterize the chemical composition consisting of (proximate, amino acids, and fatty acids) in boiled shell snails, obtain the yield of boiled shell snail extract, and obtain the active compounds contained in boiled shell snails. The research method was divided into 4 tests including analysis of proximate, amino acids, fatty acids, and bioactive ingredients using qualitative descriptive analysis. The results showed that boiled coconut snails had proximate contents such as 82% water content, 25.63% protein, 4.60% fat, 2.71% ash content, and 0.24% carbohydrates. The yield of boiled cucumber snail extract was 2.78% methanol, 0.44% ethyl acetate, and 0.15% n-hexan. The amino acid content consists of 9 essential amino acids and 6 non-essential amino acids with a total amino acid of 32.41%. The total fatty acid content is 20.68% which consists of 14 types of saturated fatty acids, 5 types of unsaturated fatty acids, and 3 types of polyunsaturated fatty acids, and has omega-3 of 2.84%, omega-6 of 0 .85%. Boiled coconut snail contains active compounds such as alkaloids, flavonoids, hydroquinone phenols, saponins, steroids, and tannins.
