Abstract

The purpose of this research was to investigate the sensory, microbiological and chemical characteristics of naniura tilapia (Oreochromis niloticus) with different types of acid and marinade time. The research was conducted on May until October 2015. This research used a Factorial Randomized Block Design (FRBD) two factors, the type of acid factor (Jungga citrus, lime, and citric acid) and marinade time factor (3 hours and 5 hours). Each treatments was replicated three times. The attributes observed were sensory test, pH, water content, and microbiological/TPC. Proximate and amino acid analysis will be done for all 3 hours marinade treatment. The results of organoleptic test showed that treatment of acid type and marinade time did not significantly affect the appearance and meat consisten but significantly affect on taste and aroma. The results of analysis TPC Jungga citrus treatment with lime showed the same value. While the value of TPC citric acid was higher but still safe for consumption. The results of proximate analysis for the three types of acid showed that Jungga citrus is the best nutrient content that the water content 63.25%, ash content 3.46%; 7.40% fat content, protein content 25.90% and carbohydrate 0.98 %. Analysis of the amino acid profile in naniura produced 17 amino acids, 9 essential amino acids and 8 non-essential amino acids

Abstract

The purpose of this study was to determine the characteristics of the snakehead fish pempek with broccoli addition as a functional food. The design used is a randomized block design with 5-stage treatment that was repeated 3 times. Factors treatment consists of adding broccoli concentrations (0%, 5%, 10%, 15% and 20%). Parameters that observed were physical analysis (elasticity, lightness, chroma and hue), sensory analysis (texture, appearance, color and flavor), proximate analysis, levels of calcium, fiber content and antioxidant activity. Results of research conducted showed that the addition concentration of broccoli into pempek snakehead fish has significant effect (p <0.05) on the physical characteristics and sensory. The average value elasticity ranged from 343.06 to 559.66 gf, lightness 53.1% to 60.20%, chroma 8.36% to 13.23%, and hue 70.23o up 93.8o. Based on the physical parameters (elasticity) and sensory found that treatment A1 (5% addition of broccoli) is the best treatment with 40.89% moisture content, 1.15% ash content, 0.16% fat content, 7.39% protein content, 48.14% carbohydrate content, 2.24% crude fiber content, 106.5 mg/100 g the level of calcium, and 202 ppm antioxidant activity contents

Abstract

This study attempts to know the quality of snakehead (Channa striata) being smoked by tools with different resources of the smoke. This study was conducted from April 2015 until May 2015 in Complex Independent Kayu Agung, Bioprocess Laboratory of Chemical Engineering, Faculty of Engineering, Technology Laboratory of Fisheries, Faculty of Agriculture, University of Sriwijaya, and the Central Laboratory of Agro Industry Bogor. The method used is a randomized block design factorial (RAKF). This research used treatment were tools (system cabinet, conventional systems) and resources of the smoke (wood-fighting, shell). The parameters observed were proximate analysis (moisture content, protein content, fat content, ash content, carbohydrate content) levels of benzo[a]pyrene and benzo[a]anthracene. Based on the test design randomized factorial (RAKF), treatment of tools with different resources of the smoke (p>0.05) showed the results of analysis of water content, protein content, fat content varies for each treatment, while ash and carbohydrate content showed the results is not different for each treatment. The observation of the levels benzo[a]pyrene analysis on smoked snakehead (Channa sriata) (p>0.05) showed different results for each treatment and results of benzo[a]anthracene analysis showed different for each treatment. The results of analysis of benzo[a]pyrene was below the maximum threshold of Indonesian National Standard, FAO and WHO.

Abstract

The objective of this research was to determine the effect of substitution of glutinous rice flour with seaweed for proximate, physic, sensory and microbiology. The research was conducted in March and April 2014 in Laboratory of Fisheries Technology and Laboratory of Bioprocess, Chemical Engineering Department, Sriwijaya University, Indralaya. This research used non factorial complete randomized design with four treatments and repeated twice. Glutinous rice flour was substituted with different concentration of seaweed A1 (12.5%), A2 (25%), A3 (37.5%), A4 (50%). The parameters observed were proximate analysis (water content), texture analysis, sensory (colour, texture and taste) and microbiology test. The results showed that substitution of glutinous rice flour with seaweed was not significant on hardness and water content. Based on analysis, the composition of the value obtained around 23.83-29.83% water content and 184.6-349.34 gf hardness analysis. Hedonic test was significant on colour and taste but not significant on texture. Microbiology test showed that engkak ketan is safe for eat on H0

Abstract

The objective of this research was to investigate the physical and chemical characteristics of bivalvia pempek (Pilsbryoconcha sp.) by using fasting pre-treatment bivalvia to the raw material and different pempek formulation. This research was conducted on February until July 2014 at the Laboratory of Fishery Product Technology, Chemical Laboratory of Technology of Agricultural, Faculty of Agriculture, and Bioprocess Laboratory of Department of Chemical Engineering, Faculty of Engineering, Sriwijaya University. The Factorial Randomized Block Design was used with two treatment factors that were repeated twice. The treatment factors were consisted of pre-treatment to the bivalvia (without fasting and fasting for 24 hours) and comparison of  the composition of bivalvia meat and tapioca flour (1:2, 1:1, and 2:1). Parameters observed were physical analysis (gel strength and degree of white) and chemical analysis (water content, ash, protein, fat, and carbohydrate). The results of this research showed that average value of gel strength of bivalvia pempek ranged from 208.20 gf to 463.70 gf and degree of white percentage ranged from 45.47% to 51.33%. The average value of the water content ranged from 85.50% to 84.20%, ash content from 0.55% to 0.90%, protein content from 3.82% to 7.31%, fat content from 1.26% to 1.91%, and carbohydrate content from 9.83% to 12.05%. The best treatment was fasting pre-treatment by using water for 24 hours with a ratio 50% of bivalvia meat and 50% of tapioca flour (1:1)
