This research aimed to know the shelf life of mullet fillet with basil leaves extract treatment in different concentration based on the amount of bacteria contained on mullet fillet during low temperature storage. The research was conducted at The Central Laboratory and The Laboratory of Fishery Product Processing, Padjadjaran University, Jatinangor. The method used in this research was experimental with four treatments by duplo. Basil leaves extract treatment concentrations were given in 0%, 1.5%, 3% and 4.5% concentrations, soaked for 30 minutes and stored at low temperature (5-10℃). The observations for grey mullet fillet with 0% concentration (without soaking on basil leaf extract treatment) were made on the 1st, 3td, 5th, 6th, 7th, 8th and 9th day of research. The observations for 1.5%, 3% and 4.5 concentrations were made on the 1st, 3rd, 5th, 6th, 7th, 8th, 9th, 10th, 11th and 12th day of storage period. The parameters observed in this research was the amount of bacteria. The result of research showed that the use of basil leaf extract in concentration of 3% on mullet fillet during low temperature storage has the longest shelf life, that was until 11 days with total amount of bacteria about 4.55 x cfu/g.
This research aimed to know the shelf life of mullet fillet with basil leaves extract treatment in different concentrations based on the number of bacteria contained on mullet fillet during low-temperature storage. The method used in this research was experimental with four treatments in double measurements. Mullet fillets were soaked for a half-hour in different concentrations of Basil leaves extract (0%, 1,5%, 3%, and 4,5%) and stored at low temperature (5-10℃). The parameters observed in this research were the number of bacteria, pH measurements, and weight loss. Based on the results of this study it can be concluded that the use of basil leaves extract with a concentration of 3% in mullet fillet during low-temperature storage has the longest shelf life of 11 days with the amount bacteria of 4.55 x cfu/g, pH value of 6.55 and weight loss value of 20,00%.
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.
