One example is the use of green solvents to <br>replace the conventional hazardous solvents that are used extensively in industry. Palm oil contains vegetable <br>oil which has many types of small components such as carotenoids, which have a natural source of <br>provitamin A and are able to supply a relatively expensive source of vitamin A. Carotenoid compounds <br>related to palm oil are useful ingredients for users who are sought by antioxidants. In this study, <br>carotenoids in palm oil was extracted using a solvent extraction method with methanol and a Deep Eutectic <br>Solvent (DES) as a co-solvent. DES which used was DL-Menthol-based DES as a Hydrogen Bond Donor <br>(HBD) and acetic acid and lauric acid as Hydrogen Bond Acceptors (HBA) which were reacted with 1: 1 and <br>2: 1 molar ratios. DES was formed in the characterization of its physicochemical properties which include: <br>Viscosity, Density and pH while characterization of the functional groups using FTIR. The optimum <br>conditions for carotene extraction in this study were 212.7 ppm using DES MLA, while for the concentration <br>of β-carotene obtained 0.156 ppm. These results showed that the DES solvent as a co-solvent can increase the <br>yield of carotene extraction in crude palm oil.</p>}, number={74}, journal={GEOMATE Journal}, author={Renita Manurung and Alwi Gery Agustan Siregar}, year={2020}, month={Oct.}, pages={131–137} }
