Abstract
Betacarotenes molecules extractions using acetic acid (99% of purity) as solvent followed by distillated water neutralization or hexane solvent to get back betacarotenes. To obtain pure betacarotenes molecules, distillation step is necessary for the second process which use hexane solvent; however for the first process which use distillated water neutralization, decantation step is enough. The first process is energetically profitable. Unrefined palm oil which contains betacarotenes molecules with triglycerides and grease acids is used as model product for betacarotenes extraction. Both of the two processes have extraction rate more than 27% which increases proportionally with the weight of unrefined palm oil used for extraction.
Highlights
Betacarotenes molecules have been widely used in food and pharmaceutical industries
This paper show two news processes to extract betacarotenes molecules
The first process use distillated water to obtain pure betacarotenes molecules after decantation whereas solvent hexane is used for the second process and distillation is necessary to separate pure betacarotenes molecules
Summary

Betacarotenes molecules have been widely used in food and pharmaceutical industries They were seen in many natural products such as: palm grains, carrots, tomatoes, spinach, etc.... This paper show two news processes to extract betacarotenes molecules. The main of these processes is the first step which use acetic acid 99% purity like solvent extraction. Unrefined palm oil which contains betacarotenes molecules with triglycerides and grease acids is used as model product for betacarotenes extraction. Both of the two processes have extraction rate of pure betacarotenes more than 27% which increases proportionally with the weight of unrefined palm oil used for extraction
