The invention particularly relates to a method for removing harmful ingredients in carotenoid. The method comprises the following steps that 1, a carotenoid product is cleaned with alcohol solvent to obtain a product phase and a solvent phase; 2, the product phase is concentrated to remove the solvent to obtain a cleaned carotenoid product, and n-hexane is added to prepare a solution S1; 3, the solution S1 obtained in the step 2 is sampled and introduced into a silicagel column, n-hexane and ethyl acetate serve as mobile phases, gradient elution is performed, and eluant S2 is collected; 4, the solvent in the S2 is removed, and the high-purity carotenoid product is obtained. In the whole separation and purification process, the product recycling rate is high, the stability is good, technological operation is easy and convenient, the automation degree is high, and the method can be further widely applied to industrial production. 本发明具体涉及种去除类胡萝卜素中危害成分的方法，包括以下步骤1）、将类胡萝卜素产品用醇溶剂清洗，得到产品相和溶剂相；2）、产品相浓缩去除溶剂，得到清洗后的类胡萝卜素
