Abstract

Manual oyster shucking is a crucial process in the seafood processing industry that significantly impacts the quality and value of the final product. This study investigates the manual oyster shucking techniques employed by Nozomi Suishan Company in Okayama, Japan. Observational methods and interviews were used to understand the shucking procedures, challenges faced, and efforts to improve efficiency in the process. The research findings indicate that the use of traditional tools and operator skills play a key role in the success of this process. This study provides important insights for the seafood processing industry to enhance operational efficiency and maintain the quality of the final product.

Abstract

Red Nile tilapia (Oreochromis niloticus) fillet is a highly nutritious aquaculture product but is prone to spoilage, thus requiring environmentally friendly preservation innovations. This study aimed to evaluate the effect of fermented rice washing water with varying vinegar concentrations on the organoleptic characteristics of red tilapia fillets during cold storage. The research was conducted experimentally at the Laboratory of Fishery Product Technology, Universitas Padjadjaran, using five vinegar concentration treatments (0%, 0.5%, 1%, 1.5%, and 2%), and organoleptic parameters observed included appearance, odor, mucus, and texture. Data were analyzed using the Friedman test and Bayesian analysis. The results showed that the treatments significantly affected fillet shelf life, particularly in maintaining appearance and mucus up to day 11 of storage. The 1% vinegar concentration was identified as the most effective treatment in preserving fillet freshness during refrigeration. In general, the combination of fermented rice washing water and vinegar can serve as a natural preservative alternative to extend the shelf life of fishery products.
