MUTU KIMIA DAN ORGANOLEPTIK KECAP IKAN LAYANG (Decapterus spp.) DENGAN PENAMBAHAN ENZIM BROMELIN

Abstract

Fish sauce is a fishery product made from fish meat raw materials in two ways: traditional fermentation and enzymatic fermentation. Fish sauce is easy and cheap to make and is popular with the public. Fermentation breaks down complex compounds in the fish body into simpler compounds by enzymes originating from the fish's body itself or microorganisms and taking place under controlled environmental conditions. One of the factors that influence fermentation activities is the type of enzyme used. Bromelain enzyme is a type of sulfhydryl protease enzyme that can hydrolyze protein—adding enzymes before fermentation can shorten the time in making the fish sauce (because there is no need for adaptation time for microorganisms to produce enzymes that can hydrolyze protein). This study aimed to determine the effect of bromelain enzyme concentrations on the chemical and organoleptic quality of flying fish sauce (Decapterus spp). The research results showed that the enzyme bromelain concentration has a very significant effect on chemical quality (viscosity) and organoleptic quality (odor and color). The K1 treatment (200 ml) had the highest value on the assay of viscosity (3,698%), aroma (2,425), and color (2,738).
