【 摘 要 】

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