Abstract

Fish and fishery products are perishable foodstuffs. One technology to prolong the shelf life of fish is gamma irradiation. Irradiation is able to break the bonds of bacterial DNA chains, thereby inhibiting bacterial growth. The application of irradiation technology will certainly be much more effective when combined with other preservation technologies, such as storage at cold temperatures. In this study, skinless jenaha fish fillet (Lutjanus sp.) was irradiated at doses of 0 kGy, 3 kGy, 5 kGy, and 8 kGy. After being irradiated at a certain dose, fish fillets were stored for 6 days at a cold temperature of 5oC. Based on the results of the proximate analysis, it was found that irradiation technology did not cause significant changes to the moisture content, ash content, and fat content but slightly reduced the protein content of fish fillets. Furthermore, it was found that in terms of pH, fish fillets that were not irradiated and irradiated fish fillets were still categorized as fresh fillets until storage on the 6th day. Although the amount of bacterial contamination in fish fillets that were not irradiated was much greater than that of irradiated fish fillets, the number of bacterial contaminants in all treatments of fish fillets was still below the threshold set by SNI 7388: 2009. The pH value and the amount of bacterial contamination in all treatments Fish fillets tend to increase with the length of the storage process.

Abstract

Mangrove are plants that are commonly found on the coast of Indonesia. However, although mangrove are rich in nutrients and antioxidants, they have not been widely used as consumer goods. Product development from mangrove fruits as raw materials is required, including analog coffee made from the mangrove fruit of Rhizophora sp. and Sonneratia sp. The purpose of this study was to determine the proximate levels, antioxidants and consumer preferences through hedonic testing of each mangrove coffee production. Three raw material treatments used in this study were pure commercial ground coffee arabica type (K0) as a control, analog coffee made from the mangrove fruit Rhizophora sp. (K1), and Sonneratia sp. (K2). The results showed that the percent moisture content was in the range of 3.33-7.31% and the ash content was in the range of 2.57-3.16% of the two parameters, both samples (K1 and K2) had meets the standard SNI for coffee. 01-3542-2004. While the fat content is 9.06% - 12.6% and the protein content 7.09-11.59% of the two parameters, the highest value was achieved with the K2 treatment. Based on the antioxidant activity test in % of the inhibitory units, the percentage results were between 61.63-77.15% with the highest value K2 achieved. Based on the hedonic test, the preference for color (neutral-like), aroma (like), taste (like), texture (like). Differences in the raw materials used have a significant effect on the aroma and color, while taste and texture do not affect the preference.
