Abstract

This study investigated how the color and β-carotene content of crude palm oil (CPO) vary as it is processed into Red Palm Olein (RPOn). Significant changes in color and β-carotene content (measured by ΔE values) were observed at each refining stage, including water degumming (ΔE = 8.15), fractionation (ΔE = 7.31), and deodorization (ΔE = 6.88). β-carotene decreased by 2.77 ppm at the water degumming step and by an additional 1.92 ppm at the fractionation stage. Interestingly, during deodorization, the β-carotene content slightly increased to 51.39 ppm compared to the initial value of 53.59 ppm. The final RPOn product retained a β-carotene content of 53.48 ppm, nearly matching the initial CPO level despite notable color changes. This study confirms that proper refining techniques can retain most of the nutrients in palm oil but significantly affect the color characteristics.
