Abstract :

ABSTRACT Various kind of molluks (Bivalves) are source of animal protein. Moreover, Bivalves are sea biota which act as heavy metal biomonitor at coastal area. This research was conducted to investigate cadmium, protein and organoleptic level in Bivalves; also to prove the descent of their level by vinegar’s soaking. This research was a laboratory experimental research with pre and post test design. Research had been done during the period of April – December 2007. Kerang batik (Paphia undulata) and kerang darah (Anadara granosa) were taken as samples because those kind of Bivalves were easy to be found and were generally consumed by people around Surabaya. Heavy metal cadmium was analysed by AAS with destruction method and quantity of protein was observed by determining total nitrogen (N) with Kyedahl desctruction method. While organoleptic examination was done with sensory modality of eyes, nose, and skin. From laboratory result, it was figured out that heavy metal cadmium level in Anadara granosa was more than its cut off value. Based on laboratory work, it was known that Paphia undulata and Anadara granosa were very potential protein sources. Shellfish organoleptic smells putrid, the texture was soft but rubbery. Anadara granosa colored red-brownish while Paphia undulata colored white-brownish. After vinegar’s soaking, heavy metal level in both of those Bivalves were decreased and so their protein. Their organoleptic condition was changed into vinegar’s aroma, harder and rubberer while the color was relatively paler. As conclusion, soaking process with vinegar 12,5% or 25% had decrease heavy metal level in Paphia undulata and Anadara granosa with no different of protein content. To know vinegar’s potential as chelating agent, it is advised to soak Bivalves with clean water as contol. Protein contents in Bivalves should be more analysed with more specific method. Sanitation and hygiene were very important while cooking Bivalves to get safe and nutricious food.
