胡萝卜粉中提取类胡萝卜素的工艺研究

摘要

Use organic solvent extraction method to measure the carotenoids from carrot powder.By controlling the extraction time, extraction temperature, extraction solid-liquid ratio, extraction times, to explore the effects of various factors on the extraction experiment and obtain the optimal extraction single factor.Use orthogonal experiment to obtain the best experimental conditions for carotenoids.The best conditions determined by experiment are as follows: the extraction solid-liquid ratio is 1∶15, extraction temperature is 50 ℃, extraction time is 1 h, extraction times is 3.Under the optimal extraction conditions, the extraction yield of carotenoids from carrot powder is 88.88 mg/100 g.%利用有机溶液浸提的方法,将胡萝卜粉中含有的类胡萝卜素浸提测量,实验过程中经过对实验时间、实验温度、实验料液比、提取次数的控制,探究各个因素对浸提实验的作用程度的大小,从而获得最优的浸提单因素,之后经过正交实验,获得类胡萝卜素的最佳实验条件.实验确定的类胡萝卜素的提取条件最佳情况是:浸提料液比1∶15、实验温度50 ℃、实验时间1 h、浸提次数3次.在上述最优浸提条件下,实验最终获得的浸提类胡萝卜素的得率是88.88 mg/100 g.
