Abstract

The red snapper fillet industry only uses 40–50% of its fish meat; the rest becomes waste. Red snapper fillet waste can be used as raw material for fish oil rich in Polyunsaturated Fatty Acid through the extraction process. Extracted fish oil quality can be improved through a neutralization process. This research aims to determine the degree of Baume NaOH that can produce fish oil with the best physicochemical properties. This study used a simple completely randomized design with three replications. The results showed that the difference in the degree of Baume NaOH significantly affected all characteristics of fish oil except yield and density. The neutralization process with the addition of NaOH 16°Be effectively improves the quality of fish oil and can maintain the unsaturated fatty acid content of fish oil. Neutralized fish oil has the characteristics of an acid number of 2.67 mg KOH/g, a peroxide value of 0.79 meq/kg, a p-anisidin number of 1.34 meq/kg, and a total oxidation number of 2.90 meq/kg. Identification of fatty acids and heavy metal contamination in fish oil before and after neutralization showed that the dominant fatty acid in fish oil was in the form of saturated fatty acids (50.58-67.51%) and heavy metal contamination in the form of arsenic 3.61-4.07 ppm.

Abstract

Carrots (Daucus carota L.) are vegetables of the Apiaceae family that contain carotenoids, flavonoids, polyacetylenes, vitamins, and antioxidants. One of the carotenoid derivative compounds is beta-carotene. However, neither carotenoids nor their derivatives are stable on oxidation and easily degraded when exposed to light, oxygen, acids, and heat during food processing and storage. Microencapsulation with foam-mat drying method is an alternative to maintain the stability of beta carotene pigments. The research aimed to study the effects of the red-snapper bone gelatin and maltodextrin ratios on characteristics of the encapsulated β-carotene. This research is used as a reference for literature regarding the development of halal gelatin and its application as a coating material for pigment microencapsulation. This research used a randomized block design with one factor, the ratios of gelatin and maltodextrin were GM 1 (1:1); GM 2 (1:1.5), GM 3 (1:2), and GM 4 (1:2.5). The results of the research showed that the ratio factors of gelatin and maltodextrin had a real impact on yield, water content, total carotenoids, surface carotenoids, solubility, encapsulation efficiency, rehydration ratio, bulk density, color intensity, and morphological observation using an optical microscope. The results showed the best treatment resulted in the ratio of the GM 1 (1:1) with the yield of 9.84 percent, the water content of 8.8 percent, total carotenoids of 203.85 mg/g, surface carotenoids of 2.01 mg/g, the solubility of 63.67percent, encapsulation efficiency of 99.15 percent the rehydration ratio of 259.70 percent, the bulk density of 0.3532 g/m, and color intensity (L: 46.6; a+: 28.1 and b+: 19.2). Red snapper bone has the potential to be used as a source of gelatin which has high encapsulation efficiency.

Abstract

Gelatin is a material produced from the partial hydrolysis of collagen sourced from the skin and bones of farm animals such as cows and pigs. Gelatin has been used for coatings because it has high permeability and dissolves in warm conditions, so the matrix cross-links are strong. The red snapper fillet processing industry produces 11.2-15% of waste, such as bone which has not been utilized optimally. The objective of this study was to determine the characterization of red snapper bone gelatin as a source of halal gelatin and measure its ability as a coating material for β-carotene pigment microencapsulation. Results showed the characteristics of red snapper bone gelatin with a yield of 10.71%, water content of 9.63%, protein content of 34.06%, ash content of 7.62%, gelatin fat content of 0.28%, and color intensity (L: 62.6). ; a+: 13.3 and b+: 30). The obtained halal gelatin was applied as a coating material for β-carotene pigment microencapsulation through the foam-mat method. It resulted in encapsulation with a yield of 16.75%, water content 9.25%, total carotenoid content 145.49 mg/g, surface carotenoid content 2.04%, solubility 78%, encapsulation efficiency 98.22%, color intensity (L: 50; a+: 29.9 and b+: 14.6), the particle size of 1004.04 μm and irregular shape.

Abstract

Analysis of the chemical properties of white bread whose formulation is modified by substitution of coconut dregs flour and avocado seed is very important to do to find out how much increase in dietary fiber content in white bread and to determine the content contained in it, which can affect the quality of the white bread. The research aimed to study the effects of coconut dregs flour and avocado seed ratios on chemical properties and daily index sufficiency of white bread. This research used a randomized block design with one factor, the ratio of white flour, coconut dregs flour and avocado seed flour is P0 (control), P1 (90%:5%:5%), P2 (85%:10%:5%), P3 (80%:15%:5%), P4 (75%:20%:5%), and P5 (70%:25%:5%). The results of the research showed that P5 white bread had the lowest water content of 35.10%, P0 white bread had the lowest ash content of 0.66%, P5 white bread had the highest fat content of 12.34%, P0 white bread had the highest protein content of 9.11%, P1 white bread has the highest carbohydrate content of 45.43%, P5 white bread has the highest crude fiber and dietary fiber content, respectively 7.78% and 17.92%. The substitution ratio of coconut dregs flour and avocado seed flour in all treatments does not significantly affect the value of the daily index sufficiency.
