Proximate analysis of smoked etak (Corbicula flueminea) tissue

Abstract

In Kelantan State, Malaysia people consumed smoked Corbicula fluminea, as a special snack. Smoked Corbicula fluminea is raw Asian clam that is marinated by using salt, sugar, garlic, shallots, lemongrass, ginger and monosodium glutamate (MSG) being subjected to the smoking process. So far, people consumed it without knowing the nutritional contents of them. Therefore, this study aims to determine the proximate composition (moisture, ash, crude fat, crude protein and carbohydrate) of C. fluminea. The present study focused on the proximate composition in C. fluminea soft tissue that has undergone the smoking process in a modified oven, with optimum temperature, airflow and time. Proximate composition was analysed according to the Association of Official Analytical Chemists standard method (AOAC). Based on the analysis, the ranged of moisture content (MC) in Pasir Mas station is between 76.16±2.72 - 78.60±1.66% and Tumpat station between 76.13±2.22 - 79.30±2.09%,ash content (AC) between 3.12±1.21 - 3.70±0.95% (Pasir Mas) and between 2.96±0.73 - 3.69±0.84 (Tumpat). On the other hand, crude fat (CF) content between 7.92±1.26 - 9.59±1.31% (Pasir Mas) and between 7.71±1.30 - 8.99±1.70% (Tumpat). Crude protein (CP) was recorded between 8.00±0.82 - 8.64±0.66% (Pasir Mas) and between 7.91±0.51 - 9.05±0.67% (Tumpat) and carbohydrates content (CC) was recorded between 1.44±1.33 - 3.14±1.48% (Pasir Mas) and between 1.57±1.01 - 2.83±1.24% (Tumpat). In conclusion, smoked C. fluminea is good to eat because it has high proximate elements and does not harm the health of its fans.
