Until today, the utilization of Lomek fish is still relatively minor, just only drainage and salinity (marine and fishery department Riau province, 2008). To increase the utilization and lomek fish consuming need a processing product of fishery. Diversification product is an alternative in making a processing product of fishery. Diversification way is one of a processing fish products become a various type of meal, thus it invites society interest to consume. A type of diversification product is fumigation. Diversification of lomek fish products is generally has, but it is just dehydrated and salted. The location of Fumigation is really hard to find. For that reasons, the researcher tries to take the lomek fish as a basic material of this research. in addition, researcher also add the citronella extract in processing of smoky fish to see the effect of adding the citronella extract concerning about the taste and the aroma of lomek fish products.Item Quality Characteristics of Cryptopterus Catfish Cracker Fortified With White Mushroom (Pleurotus ostreatus)(2013-01-29) Paulo Bukit, JimiThe research was intended to determine the quality characteristics of Cryptopterus catfish crackers fortified with white mushroom.
