Abstract

Squid (Loligo sp.) is one of fisheries commodities export in Indonesia. Squid has cartilage that can be utilized in the food and non-food sectors. The inner skin of the squid cartilage contains chemical compounds are chitin and chitosan. The objectives of this research are to produce chitosan from squid cartilage and tested the antibacterial effectiveness of chitosan in bacteria Staphylococcus aureus and Escherichia coli. The research method was carried out in twophase; the manufacturing phase of chitosan from squid cartilage and the testing phase for the antibacterial activity of chitosan. The results of the first phase of this study indicate that the chitosan produced meets the quality standards of chitosan with water content 7.82% (bk), ash content 0.57% (bk), nitrogen content 3.18% (bk) and degree of deacetylation 87.43%. Further more the results obtained in the second phase showed that the higher of chitosan concentration, the greater of inhibition zone in the tested bacteria. The best antibacterial activity was found at 0.8% chitosan concentration, with an inhibition zone of 12.8 ± 0.06 mm in E. coli and 11.1 ± 0.12 mm in S. aureus. At a concentration of 0.8% showed a greater inhibitory value when compared to 70% alcohol.

Abstract

Generally, nuggets on the market are made from chicken meat but today the price of chicken meat is high so it needs alternative raw materials in making nuggets. One of the raw materials that can be used for making nuggets is tilapia meat. Tilapia has high protein and a soft texture. To increase the attractiveness and nutritional value of nuggets, so vegetables can be added. Carrot is one of the vegetables that can be used as an added ingredient in tilapia fish nuggets because it contains ?-carotene which is a source of ?-tocopherol, dietary fiber, ascorbic acid, tocopherol, and natural antioxidants. The purpose of this study was to determine the effect of adding carrot flour with different concentrations to the organoleptic values and levels of ?-carotene of selected tilapia fish nuggets. This study uses a quantitative research method with a Completely Randomized Design (CRD) model with 4 treatment levels and 3 replications. The treatment in this study refers to the concentration of carrot flour were K0 (0%), K1 (8%), K2 (10%), and K3 (12%). Parameters observed were organoleptic (color, flavor, taste, and texture) and ?-carotene. The results showed that the addition of carrot flour had a significant effect on the organoleptic value of tilapia nuggets (p<0.05). The best treatment in this study was the addition of 12% carrot flour concentration (K3) with panelists acceptance rate at color 7.83 (like), flavor 7,96 (like), taste 7,52 (like) and texture 7,60 (like). K3 treatment was the selected tilapia nugget with the value of ?-carotene 12.09 ppm (bk) and 24.03 ppm (bb).

Abstract

Chitosan has gained high interest in recent times to extend the shelf-life of fish product due to its nontoxicity, biodegradability, biocompatible and antibacterial activity. This research was aimed to determine the antibacterial effect of chitosan on the shelf-life of tilapia fillets at room temperature storage (25-27 oC). This study used a actorial randomized design (RAF) with two factors, namely antibacterial treatment consisting of 3 levels (positive control with distilled water immersion on tilapia fillets, immersion of tilapia fillets with 0.8% chitosan and negative control with 10 ppm chlorine immersion in tilapia fillet) and observation time consisted of 3 levels (0 hours, 6 hours and 12 hours observations). Antibacterial treatment consisted of  3 levels, namely. Each treatment was carried out in three replications. The data were analyzed using analysis of variance (ANOVA) and the duncan multiple range test (DMRT) at a 95% confidence level. The results of the research showed that chitosan was able to suppress bacterial growth and suppress the increase in TVB values at room temperature storage for 12 hours, indicated by the significant difference in the total number of bacteria and TVB values with chlorine and controls (p<0.05). These indicated that chitosan has a function as a natural antibacterial to replace chlorine in the shelf-life extension of tilapia fillets.

Abstract

Fish have the potential to be a natural source of flavor. Hence, they can be used as the main ingredient in flavor enhancers. This research examines the characteristics of flavor enhancers made from Indo-pacific tarpon produced using foam-mat drying technology. The formulations were the ratio between the weight of fish fleshes and additives namely 30:70 (A); 40:60 (B); 50:50 (C); 60:40 (D); and 70:30 (E). The test parameters included yield, pH, Maillard reaction product, sensory (preference) and proximate value. The best formulation was based on proximate value. The results showed that the different formulations significantly affected the yield, pH, and Maillard reaction product (p0,05). The lower the fish flesh used in the formulation, the higher the yield and Maillard reaction product, while the pH decreased. The effectiveness index test based on sensory value (preference) showed that the formulation D (60:40) was the best formulation that contained water of 8.49 ± 0.30%; ash of 33.03 ± 0.10%; protein of 29.67 ± 0.26%; total fat of 2.00 ± 0.15% and carbohydrates of 26.74 ± 0.10%.

Abstract

ABSTRACTThis study aims to determine the concentration of the selected soy protein isolate (SPI) emulsifying agent (the most preferred by panelists) and chemical characteristics of tilapia surimi sausage. This study used a quantitative research method with a completely randomized design (CRD) model with one treatment factor, namely the addition of soy protein isolate (GPA), which consisted of 4 levels of treatment, each of which was repeated 3 times, the treatment was treatment A (control or without the addition of SPI), treatment B (12% SPI addition), C treatment (13% SPI addition) and D treatment (14% SPI addition). The organoleptic parameters tested were appearance, color, aroma, taste and texture, while the chemical parameters were emulsion test and proximate analysis (water content, ash, protein and fat). The results showed that the sausages were selected based on the hedonic test or preference for adding soy protein isolate concentration (GPA) of 12% with an appearance parameter value of 7.18 (like), color of 7.06 (like), taste of 7.38 (like). ), aroma of 6.48 (rather like) and texture of 7.02 (like). Sausages with the addition of 12% GPA concentration had chemical characteristics in the form of emulsion stability of 82.18% and proximate analysis of water, ash, protein and fat content respectively of 60.40%, 0.61%, 15.97% and 1 .60% (fulfills SNI 7755:2013). Keywords: soy protein isolate, organoleptic, tilapia surimi, sausageABSTRAKPenelitian ini bertujuan untuk menentukan konsentrasi bahan pengemulsi  isolat protein kedelai (IPK) terpilih (yang paling disukai panelis) dan karakteristik  kimia dari sosis surimi ikan nila.

Abstract

Red tilapia is in demand by the public as a consumption fish because it has several advantages, namely thick flesh and high nutritional value. This study aims to determine the chemical characteristics and fatty acid profile of red tilapia with harvesting ages of 16, 20 and 24 weeks. This research method used a completely randomized design (CRD) and each carried out 3 replications. The analysis used is the actorial pattern with one factor (16, 20 and 24 week harvesting age treatment). Data were analyzed using Analysis of Variance (ANOVA) and Duncan Multiple Range Test (DMRT) at 95% confidence level. The results showed that the water and protein content increased with increasing harvesting age for red tilapia, while the ash and fat content decreased. The highest water and protein content at 24 weeks of harvest were 80.17% and 17.85%, respectively. Fatty acids in red tilapia consist of 4 SAFA, 1 MUFA and 3 PUFA. The highest fatty acid content of red tilapia, namely palmitic fatty acid, was 27.26% at harvest age of 24 weeks and increased with increasing harvest age.
