KARAKTERISTIK HIDROLISAT PROTEIN IKAN BANDENG (Chanos chanos Forsk) DENGAN KONSENTRASI ENZIM BROMELIN YANG BERBEDA Caracteristic of Milkfish (Chanos chanos Forsk) Protein Hydrolysate as effect of Different Bromelin Enzyme Concentration
Ikan Bandeng berpotensi menjadi bahan baku hidrolisat protein ikan karena kandungan protein tinggi dan potensi produksi cukup melimpah. Enzim Bromelin merupakan salah satu enzim protease yang dapat membantu dalam mempercepat reaksi hidrolisa protein. Penelitian ini bertujuan untuk mengetahui pengaruh konsentrasi enzim bromelin terhadap kualitas hidrolisat protein Ikan Bandeng (C hanos chanos Forks) segar. Rancangan percobaan yang digunakan pada penelitian ini adalah rancangan acak lengkap dengan perlakuan konsentrasi enzim yang berbeda (4% 5% dan 6% Parameter yang diamati adalah nilai kadar protein, lemak, air, karbohidrat, serat kasar dan rendemen. Konsenterasi enzim bromelin berpengaruh nyata pada nilai kadar protein, lemak, air, abu, serat kasar dan rendemen (P 0,05) Kondisi optimum untuk menghidrolisis daging Ikan Bandeng menjadi hidrolisat protein adalah konsentrasi enzim bromelin 6% dengan waktu hidrolisis selama 6 jam. Kata kunci Ikan Bandeng Chanos chanos hidrolisat protein ikan, enzim bromelin ABSTRACT Milkfish is potentially become the raw material of fish protein hydrolyzate because of the high protein content and relatively abundant production. Bromelin is a protease enzyme that can help on improving protein hydrolyzate quality. This research aimed to determine the effect of bromelain enzyme concentration on the quality of the protein hydrolyzate of milkfish Chanos chanos Forsk) fresh. The experimental design used in this study was completely randomized design with different concentrations of the enzyme (4% 5% and 6% as a treatment. The parameters measured were the contents of protein, fat, water, carbohydrates, crude fiber and yield. The concentration of enzyme bromelin significant effect on contents of protein, fat, water, ash, crude fiber and yield (P 0,05) The optimum conditions to hydrolyze the milkfish meat into a protein hydrolyzate used 6% bromelin enzyme at the time of hydrolysis for 6 hours.
