摘要
由现行工艺生产出来的萝卜红色素带有萝卜特殊的异味,严重地影响了该色素的使用,因而工业上急需寻求一种脱味效果好、能用于工业化生产的萝卜红色素产品的制取方法。以红心萝卜为原料,采用酶解法、壳聚糖沉淀法和双水相萃取法,结合树脂吸附法进行实验,结果表明:双水相萃取结合树脂吸附法脱除异味效果最好,粉末状成品中异味物质异硫氰酸酯的去除率高达94%,且无"返味"现象,但该法终产品的花青素含量略有降低。
Red radish pigment which produced by current processes in industry has peculiar smell which decreased its application effect.So a red radish pigment production process which has a good effect on odor substances removal and can be used for industrial production is urgently needed in industry.Experimental study on deodorization of red radish pigment derived from red radish by enzymatic hydrolysis,chitosan precipitation and aqueous two-phase extraction combined with resin adsorption method was performed.The results indicate that the method of aqueous two-phase extraction combined with resin adsorption is the best one,the removal ratio of isothiocyanate reaches 94.0%,with no aftersmell.However,anthocyanin content of powdery products produced by this method is decreased slightly.
