Fixings Agent Effect to β-caroteneStabilityof Crude Extract from Dunaliella salinaMicroalgaat Different Temperature Condition

faced for temporative β-carotene stability which is unstable and easily degraded is unstable and easily<br />degraded. The purpose ofthis researchwas to determine content and stability of β-carotene pigment in<br />D.salina with fixings addition of MgCO3 and NaHCO3 with temperature treatment as factor that influence<br />β-carotene pigment degradation during storage condition. The research method used β-carotene pigment<br />which was obtainedbymaceration and adding fixing agent (NaHCO3 0,5% and without fixings addition),<br />and was heated at temperature of (50°, 70° and 90°C), be measured the content of β-carotene pigment<br />during storage (observation hour 0, 24, 48, 72, 96, 120 and 144). Data were analyzed by analysis of variance<br />(ANOVA) and Honestly Significant Different (HSD). The result showed that content of β-carotene pigment<br />at 50°C temperature showed that stability and pH value performed slowest degradation after144 hours.<br />While stability and pH value at 90°C temperature performed fastest degradation after 96 hours. Based on<br />this study the addition of NaHCO3 gave more effective in retaining β-carotene degradation compared to that<br />of MgCO3 which showed by high stability in sample NaHCO3 0,5%, temperature 50°C in 144 hours storage<br />length.<br />
