MIKROENKAPSULASI PIGMEN BETA-KAROTEN DENGAN METODE FOAM MAT DRYING MENGGUNAKAN GELATIN TULANG IKAN KAKAP MERAH SEBAGAI BAHAN PENYALUT

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