Study on the extraction condition of β-carotene

Peng Sun

Abstract

Taking the fresh carrots as raw materials,β-carotene was extracted by using organic reagent.Extraction conditions were optimized based on single factor and orthogonal experiment.The optimum refining conditions are as follows: extraction reagent: acstone-petroleum ether is 3∶7(V/V),temperature is 50℃,extraction time is 90min,pH is 4.5,and the content of β-carotene can reach 1 375.9μg/g.
