NOVELTY - Extraction of beta -carotene from carrot, involves selecting fresh carrots, washing, drying, chopping dried carrots, crushing, cooling, naturally thawing, adding resultant product to a boiling pot, adding raw water, stirring, heating, removing slag from resultant material, adding water to resultant juice, boiling, removing slag from resultant material and repeating above process, mixing obtained juices, filtering resultant crude liquid, extracting obtained refined liquid using petroleum ether, filtering extracted solution, concentrating supernatant, spray-drying, and grinding.    USE - Extraction of beta -carotene from carrot (claimed).    ADVANTAGE - The method enables extraction of high-purity nontoxic beta -carotene with high quality, using innocuous and non-poisonous extraction solvent, by safe, simple and environmentally-friendly process.    DETAILED DESCRIPTION - Extraction of beta -carotene from carrot, involves selecting fresh carrots, removing wounds or leaf blight, cleaning the surface of resultant fresh carrot to remove stain, further washing with distilled water, drying for 2-3 hours, chopping dried carrots using a cutter, crushing in a container, placing the container in a cold box, pre-cooling at 2-4 degrees C for 3-5 minutes, cooling to 0-1 degrees C for 5-10 minutes, naturally thawing, adding resultant product to a boiling pot, adding raw water in an amount of 0.5-1 times of the material in the boiling pot, stirring, heating at 30-40 degrees C for 20-30 minutes, removing slag from resultant material, adding water to resultant juice, boiling at 30-40 degrees C for 20-30 minutes, removing slag from resultant material and repeating above process, mixing obtained juices, filtering resultant crude liquid, adding obtained refined liquid to extraction and separation machine, adding petroleum ether as extraction solvent in an amount of 3/5 of the total amount of liquid, extracting, filtering extracted solution, concentrating supernatant under reduced pressure until relative density is 1 plus minus 0.01, spray-drying concentrate, grinding dried material to a particle fineness of 2-3 mu m, and packaging.
