Abstract

Histamine is a biogenic amine that appear during post moterm phase on the fish flesh that contain high content of histidine. The higher level of histamine can be reduced by good handling practice to maintain fish quality for example: using chilling temperature. This research aimed to determine chemical and microbiology changes from longtail tuna Thunnus tonggol and the time when hdc gene can be detected during chilling temperature storage 8±3°C. This research design was a completely randomized design (CRD) with parameters of differences in fish storage time (1,2,3,4,5,6,7 days) and ice ratio 1:1. The results showed that the tuna fish experienced quality deterioration for 7 days of storage. Organoleptic values and pH decreased during storage and on the seventh day the fish were in the rigormortis phase. TVB and TPC values increased during storage and on the sixth day storage has passed the safe limit for consumption. Histamine levels of this tuna on the seventh day were 1.96 ppm. HDc gene detection using the PCR method showed negative results in each treatment. The protein profile that was formed during storage displayed to separate because of the cathepsin activity.
