ABSTRACT
Snakehead fish is one of the fish that has many benefits, almost all parts of
its body can be used, such as the bones. Fishbones are one of the raw materials
for gelatin. This study aimed to determine the effect of the use of bromelain
enzymes on the characteristics of snakehead fishbone gelatin using a non-factorial
completely randomized design (CRD) with 3 treatment levels, namely E1 (2%
bromelain enzyme), E2 (4% bromelain enzyme) and E3 (6% bromelain enzyme).
The parameters of analysis consisted of yield, viscosity, isoelectric point, pH, and
chemical composition (moisture, ash, and protein content). The results showed
that the yield of gelatin extracted with the bromelain enzyme with concentrations
of 2, 4, and 6% was 1.34-3.56%. Gelatin had a viscosity of 1.91-2.06 cP, its
isoelectric point was at pH 7.5 with the lowest protein solubility, and the pH of
gelatin ranges from 5.52 – 6.21. The chemical composition of snakehead fish bone
gelatin contained moisture, ash, and protein content ranging from 4.08-7.45%
(ww), 1.69-3.25% (ww), and 62.39-84.86% (ww). The best treatment of gelatin
extraction with bromelain enzyme using concentration of 6% resulted in the
highest yield of 3.56%, viscosity 2.06 cP, isoelectric point 8.77, pH 6.21 and
protein 84.86%.
Keywords: bone of snakehead fish, concentration of enzyme, gelatin
