Abstract

ABSTRACT This research was aimed to find out the meat and fish meal proximate composition from snakehead fish (Channa striata). The study consists of 2 stages: 1) Preparation and making of a snakehead fish meal, 2) Proximate analysis of snakehead fish meat and fish meal. The parameter that observed in the stage 1 were the yield of meat and fish meal of snakehead, in the stage 2 were water content, ash content, protein content, fat content, and carbohydrate content (by different). The results showed that snakehead fish meat with a yield 31.41% and snakehead fish meal with a yield 12,46%. Chemical composition that produced from snakehead fish meat were water content 75.35% (gw), ash content 6.89% (dw), protein content 78.38% (dw), and fat content 4.54% (dw). Chemical composition that produced from snakehead fish meal were water content 5.68% (gw), ash content 6.29% (dw), protein content 86.31% (dw), and fat content 5.27% (dw).

Abstract

ABSTRACT            Berunok sea cucumber is one of the typical marine biota on Karimun Island that has not been utilized optimally, even though the berunok sea cucumber has a high protein content, which is 6-70% in dry conditions, and is thought to be composed of several specific amino acids. Therefore, the sea cucumber has the potential to be used as a raw material for protein hydrolyzate. The hydrolysis process in the manufacture of hydrolysates more often uses enzymes, because it is safer and more profitable, one of which is the alkalase enzyme. This study aims to determine the composition of amino acids contained in the hydrolyzed sea cucumber protein with alkalase added. The research method used is experimental by conducting a series of experiments. This research consisted of 3 stages, namely: 1) making sea cucumber flour, 2) making protein hydrolyzate, and 3) amino acid analysis. Parameter analysis of this study is the analysis of amino acids. The results showed that the hydrolyzed sea cucumber protein with alkalase added to 17 types of amino acids, consisting of 9 essential amino acids and 8 non-essential amino acids. Keywords: berunok sea cucumber, protein hydrolyzate, alkalase enzyme, amino acid

AbstractThe study was aimed to find out the proximate existenceoflomek(Harpodon nehereus)fish meal and fish protein hydrolyzate. It was also aimed to determine the optimum hydrolysis time and to get the profile of amino acid from the best the lomek fish protein hydrolyzate yielded. The research was using the experiment method to conduct the processing of lomek fish protein hydrolyzate by using papain enzyme in different hydrolysis time (for 5, 6, and 7 hours). The research was composed for non factorial completely randomized design. The results showed that the different hydrolysis time was affecting to the protein content, water content, ash content and fat content of fish protein hydrolyzate produced. The best fish protein hydrolyzate was yielded by hydrolising the fish meal for 7 hours, indicated by the highest protein content (86.03%), water content (27.39%), ash content (3.65%) and fat content (0.46%). There were 17 types of amino acids found in the fish protein hydrolizate, and consisting of essential and non-essential amino acids. The types of amino acids were dominatedby glutamic acid (1.01%), in the other hands, cysteine was showingthe lowest value (0.9 %).Keywords: fish protein hydrolyzate, lomek fish,papain enzyme

Abstract This study aims to determine the effect of different papain enzyme concentrations on collagen extraction from the skin of catfish (Pangasius sp.). The method used was an experimental method with completely randomized concoctions (CRD). The treatments given consisted of E0 (Control), E1 (5% papain enzyme), E2 (10% papain enzyme), E3 (15% papain enzyme). This research consisted of 3 stages, namely 1) preparation of raw catfish, 2) deproteination of catfish skin, 3) hydrolysis of raw catfish with acetic acid.The parameters tested were collagen yield, proximate analysis (moisture content, ash content, and protein content), pH, and functional group (FTIR). The results showed that the quality of the collagen obtained increased along with the increase in the concentration of the enzymes used. This is presumably because the addition of the enzyme concentration in the collagen extraction process will increase the yield produced because the enzyme breaks the cross-linking of the collagen telopeptide and dissolves it. Based on this, the use of the optimum concentration was obtained at a concentration of 15% (E2) with a protein content of 71,60%, 14.17%water, and4.21% ash Keywords:Collagen, Catfish, Extraction, Papain Enzymes.
