Crude palm oil as a source of beta-carotene - ScienceDirect
Crude palm oil (CPO) (Elaeis guineensis) can serve as a promising source of ¦Â-carotene in developing countries where vitamin A deficiency is prevalent. Indigenously produced CPO has been evaluated for its chemical, nutritional and toxicological properties, and found to be nutritionally adequate and toxicologically safe for human consumption.

Adsorption and desorption strategy for recovering ¦Â-carotene
Palm oil contains large amount of minor compounds, such as tocopherol, tocotrienol, squalene, phytosterol, phenolic compounds and carotenoids. Regarding carotenoids, the main type present in crude palm oil is ¦Â-caroteno (56%) and ¦Á-carotene (35%), both recognized for their provitamin A activity (Hoe et al., 2020). The carotenoids market has a

Extraction of Carotenes from Palm Oil. I. Molecular
Crude palm oil was treated with phosphoric, poly-phosphoric, tartaric or oxalic acid at 80?? for 1h followed by molecular distillation. Carotene fractions were collected at 215?? and 225?? under a pressure of 6?`8?~10-3mmHg after removal of the lower boiling fractions. Carotene content was determined as ?¨¤-carotene by

Direct recovery of palm carotene by liquid-liquid extraction
Crude palm oil (CPO) contains the highest known amount of carotenoid among crops, but the harsh refining conditions of CPO degrade palm carotene. Liquid-liquid extraction (LLE) is a scalable extraction method that can be prospectively used in direct recovery of palm carotene. This study aimed to extract palm carotenes directly from CPO without
