Abstract

Carrots (Daucus carota), is the main sources of beta carotene besides tomatoes and palm oil. At present, β-carotene has been used extensively in food, industry, and medicine, so that beta carotene is of high economic value. The β-carotene in carrot can be obtained by chemical preparation. The researchers, usually to have β- carotene mainly done with organic solvents. It is very rarely done without a chemical solvent. This study aims to extract β-carotene without chemical solvent and also to determine β- carotene using UHPLC and GC-MS. Approximately 300 gram carrots, cleaned, cut into small pieces and mashed in a blender, given aqua 20 mL. separate the filtrate from that matrix. To the filtrate was then, added some chemical salt, centrifuged 5000 x g for 30 minutes to have pellet. The pellets are then removed, evaporated with the vacuum to dry at a temperature of 40o C for 48 hours. β-carotene pellets are measured with UV-vis, HPLC and GC-MS. Using column UHPLC and the mobile phase was chloroform-methanol (95: 5) with a flow rate of 1 ml /minute at a UV detector wavelength of 460 nm. The retention time examination of β-carotene and standard (sigma beta carotene) using HPLC and GC-MS was 3.75 and 9,80 minutes respectively. GC-MS examination showed ions and molecules of carotenoid. Research showed that this method can be used to be developed for the withdrawal of β-carotene in carrots and others, without any need for organic solvents.
