Abstract

Dried noodles are one of the foods favored by people in Indonesia. The main ingredient of dry noodles is wheat flour which made from milling wheat. However, we usually obtain wheat from overseas by import. Therefore, to achieve food resilience in Indonesia, it is necessary to find substitutes for local ingredients with high nutrition that can be used to make dry noodles. This research aims to investigate the characteristics of dry noodles made from Kappaphycus alvarezii seaweed flour. The method used in this study was to substitute K. alvarezii seaweed flour as much as 0, 5, 10, 15, 20, and 25% in the production of dry noodles. Analysis was carried out on its chemical composition, physical properties, and organoleptic characteristics. The results showed the best result of substitution of K. alvarezii in the 5% treatment. The chemical composition in dry noodles of this treatment showed an air content of 8.39%; ash content 3.07%; fat content 0.59%; protein content 12.43%; and 0.29% crude fiber content. Meanwhile, the results of the physical test showed7.95% cooking loss;210.5 seconds cooking time; and 89.34% water absorption. The organoleptic values obtained are color 4.60 (like); aroma 4.80 (like); texture 4.23 (like); and taste 4.20 (like).

Abstract

Milkfish satay processing has been left viscera waste that may causes environmental pollution. The viscera waste has contained omega-3 which can be extracted as fish oil. Dry rendering is a method of fish oil extracting using temperature without water addition. The temperature of extraction greatly affects to quality of fish oil. The purpose of this study was to determine the optimal temperature of extraction and characterized fish oil quality extracted from milkfish viscera. This study used dry rendering extraction methode with three different temperatures (40ºC, 50ºC, and 60ºC) and tested the yield, free fatty acids, peroxide value, p-anisidine and total oxidation, for the best fish oil will be tested for its fatty acid profile. The best treatment for extracting fish oil from milkfish viscera used extraction temperature of 50ºC with yield (6.88%), free fatty acid (4.89%) peroxide value (29.35 mEq/kg), anisidine value (4.61 mEq/kg), and total oxidation (63.53 mEq/kg). The fatty acid profile of fish oil was dominated by palmitic acid (31.17%) and also contains omega-3 such as linoleic acid, docosahexaenoate acid (DHA), and eicosapentaenoate acid (EPA).

Abstract

Bontot from Domas Village, Pontang District, Serang Regency is a fish jelly product. The manufacture of Bontot produces fish skin waste with a percentage of 10% of the whole weight of the fish. This waste can be reduced by applying the concept of zero waste in the processing of bontot which is reused as a raw material in the manufacture of gelatin. This research aims to determine the best NaOH concentration in the manufacture of gelatin from the skin of Hawaiian ladyfish (Elops hawaiensis) and to determine the effect of NaOH immersion on the organoleptic, chemical, and physical qualities of the gelatin. This study used an alkaline solution (NaOH) with a concentration of 0.1%; 0.3%; and 0.5%, which is then followed by a 6% acid solution immersion process. The production of gelatin from the skin of Hawaiian ladyfish was carried out using a one-factor completely randomized design (CRD) with 2 replications (duplo) accompanied by non-parametric analysis which was carried out for organoleptic testing with a hedonic scale using the Kruskal Wallis test. The results showed that the best combination was 0.1% NaOH and 6% HCl with a hedonic value of 3.7 with a whitish-yellow color; odor hedonic value 3.13; 11% yield; gel strength 280.43 g bloom; viscosity 36.95 cP; water content 8.75%; ash content 0.58%; and a pH value of 6.88
