It was difficult to extract corn pigments completely, for some of them were in a protein-bind state. It was better to use active carbon for the decolorization of GEON, the conditions were 40℃, stir time 6 hours, the ratio of carbon to hydrolyzate 1: 100 , but as to milk-like powder, it was better to extract pigments after spray drying.

最后，本文对玉米黄素的可抽提性也进行了初步研究，结果表明，部分色素与蛋白质结合而难以抽提，因而有机溶剂难以将色素抽提完全，对Gln活性肽营养液而言，可选用酶解后加活性炭进行脱色，脱色条件为40℃，搅拌6小时，炭液比为1∶100；而对黄粉蛋白乳粉而言，喷雾干燥后用乙酸乙酯脱色，可使酶解干燥后黄粉的异味减轻。
