This research was aimed to observe the effects of using food additives from Gracilaria powder to the structural properties and chemical characteristics of nemipterid fish sausages. Seaweed powder was originated from raw Gracilaria obtained from cultivated seaweed in Karawang waters. Five different concentrations of Gracilaria powder (0.0%, 2.5%, 5.0%, 7.5%, 10.0%) were used. The quality of the sausage was decided based on the sensory and the chemical quality. The results showed that the addition of Gracilaria powder had a significant effect on the texture and chemical quality but not to the taste, odor, appearance or fat content. The addition of Gracilaria powder at 2.5% was considered as the best treatment resulting in nemipterid fish sausage with an appearance value of 8.4, taste 7.7, odor 2.5, texture 8.7, and chemical value of moisture content 61.3%, ash content 1.52%, protein content 13.16%, fat content 0.62%.
Carbon footprint has become an important issue in the world trade, and can potentially be incorporated into sustainability and ecolabel certification schemes. As the leading seafood producers, Indonesia should start to reduce the carbon footprint of its seafood products, especially those destined for export, to minimize the impact on the environment and to safeguard its product in the world market. The present study aimed to determine the carbon footprint of frozen pangasius fillets produced at PT. KMM, Purwakarta. The carbon footprint was calculated using the Life Cycle Assessment method with a standard emission factor during 3-month observation covering post-harvest, processing, and distribution. Results showed that the total carbon footprint of frozen pangasius fillets was 1.48 kg CO2eq/kg product. The highest emission was in the processing, freezing, and storage, i.e., about 71% (mainly from electricity, ice, and refrigerant), of which refrigerant contributed 41%. The lowest CO2 emission was in the administration office and lighting (1.4%).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
