摘要
采用微生物发酵和酶促反应分开的方法（二步法）制得色泽鲜明的栀子蓝色素。结果表明，栀子果粉中与京尼平甙共存的α－藏花素是影响色素色泽的主要因素之一。用一种大网孔树脂对桅子水浸液过柱吸附，可将京尼平甙与藏花素分离。氨基酸种类对二步法形成色素的色泽影响甚大。其中亮氨酸，精氨酸和苯丙氨酸所形成色素的色泽最佳，呈美丽蓝色。
The Paper reports a method of producing brilliant gardenia blue. The results indicated that crocin of gardenia fruits is a a main effect on color of pigment formed. For this reason, pure crocin (gardenia yellow) was obtained and geniposide was purified using a reves-phase colomn chromatog. Moreover, the effect of the different aminoacids on blue pigment formation was studied. Pigment foremd from Leu, Phe and Arg appears brilliant skyblue.
