High-proportion cis-carotene extract and preparation process thereof

The invention discloses a high-proportion cis-carotene extract and a preparation process thereof. The preparation process of the high-proportion cis-carotene extract comprises the steps of (1) extraction, (2) extraction, (3) column purification and the like. The preparation method is simple in process flow and beneficial to industrialization. The purity of the prepared high-proportion cis-carotene extract is larger than 50%, the proportion of cis-isomers is high, the ratio of the peak area of total cis-beta-carotene to the peak area of all-trans-beta-carotene and the ratio of the peak area of total cis-beta-carotene to the peak area of total trans-carotene in a chromatographic analysis method are both larger than 1.0, and the content of the total cis-beta-carotene and the total trans-carotene is larger than 1.0. The extraction recovery rate of the cis-carotene exceeds 90%, and the cis-carotene is orange red in color and clear in appearance. 本发明公开了高比例顺式胡萝卜素提取物及其制取工艺，高比例顺式胡萝卜素提取物的制取工艺包括(1)提取、(2)萃取、(3)柱净化等步骤。得到高
