Extraction of β-carotenes from palm oil mesocarp using sub-critical R134a
Sub-critical extraction of palm oil from palm mesocarp using R134a solvent was conducted via the dynamic mode to investigate the ability of R134a to extract ß-carotene. The yield of palm oil and the solubility of ß-carotene were investigated at 40, 60 and 80°C and pressure range from 45-100. bar. Th...
