Analysis of β-Carotene Content in Crude Palm Oil from PT. REA Kaltim using Transesterification and Esterification Methods with UV-Vis Spectrophotometry
Keywords:
β-carotene, Crude Palm Oil, Esterification, Transesterification, UV-Vis SpectrophotometryAbstract
Crude Palm Oil (CPO) is a major source of vegetable oil containing bioactive compounds such as beta-carotene, which significantly influences the quality and nutritional value of palm oil. The beta-carotene content may change during chemical processes such as esterification and transesterification, commonly applied in biodiesel production. This study examines the effect of these processes on the beta-carotene content of CPO from PT. REA Kaltim. The esterification process utilized 0.225% sulfuric acid catalyst based on oil volume, while transesterification employed 80% sodium methoxide catalyst. Parameters observed include acid value, saponification value, and beta-carotene concentration determined using UV-Vis spectrophotometry. The analysis provides insights into the effectiveness of both chemical processes on beta-carotene stability and supports efforts to enhance the quality and added value of palm oil derivatives in the vegetable oil industry.
