摘　　要：用胡萝卜榨取的汁液提取了天然β-胡萝卜素.实验结果表明,用二水氯化钙浓度为0.7％处理,然后再以固液比1:8-1:15的石油醚作为溶剂进行萃取,可以得到比较理想的结果.The extraction of β-carotene from the juice by juicing the carrots is studied. The optimum extracting conditions are investigated. The best experimental results are: the precipitating agent is calcium chloride dihydrate, the concentration is 0.7%; the rate of solid to the extractant petroleum ethers is 1:8-1: 15.
