The influence of light on gardenia purpuretin was small, and the color of gardenia purpuretin was weak. Gardenia purpurin was stable at 80 \u2103, and the absorbance of the pigment showed a weak decreasing trend with the prolongation of time, while it had a large fading trend at 100 \u2103. pH has great influence on gardenia purpurin, and the absorbance value is the highest when pH is 6.0, so gardenia purpurin is best preserved in weakly acidic environment. Its antioxidant ability is poor, but its tolerance to reducing agents is good. Most food additives have little effect on the stability of gardenia purpurin.<\/p>\n<p><img decoding=\"async\" src=\"\/wp-content\/uploads\/replace\/0ec07fd5698bfc8097fba0868784d99f.jpeg\" alt=\"\u6800\u5b50\u82b1\u7d2b\" title=\"Gardenia purple\u63d2\u56fe1\" \/><\/p>\n<table>\n<tbody>\n<tr>\n<td width=\"251\">\u4ea7\u54c1\u540d\u79f0<\/td>\n<td width=\"296\">\u6800\u5b50\u82b1\u7d2b<\/td>\n<\/tr>\n<tr>\n<td width=\"251\">\u5916\u89c2\u548c\u989c\u8272<\/td>\n<td width=\"296\">Fine Black Powder<\/td>\n<\/tr>\n<tr>\n<td width=\"251\">\u89c4\u683c<\/td>\n<td width=\"296\">E30<\/td>\n<\/tr>\n<tr>\n<td width=\"251\">\u7f51\u773c\u5c3a\u5bf8<\/td>\n<td width=\"296\">NLT 90% \u81f3 80 \u76ee<\/td>\n<\/tr>\n<tr>\n<td width=\"251\">\u6c34\u5206\u542b\u91cf<\/td>\n<td width=\"296\">NMT 5.0%<\/td>\n<\/tr>\n<tr>\n<td width=\"251\">\u7070\u5206\u542b\u91cf<\/td>\n<td width=\"296\">NMT 5.0%<\/td>\n<\/tr>\n<tr>\n<td width=\"251\">\u91cd\u91d1\u5c5e<\/td>\n<td width=\"296\">NMT 10ppm<\/td>\n<\/tr>\n<tr>\n<td width=\"251\">\u7837\uff08As\uff09<\/td>\n<td width=\"296\">NMT 1ppm<\/td>\n<\/tr>\n<tr>\n<td width=\"251\">\u9549 (Cd)<\/td>\n<td width=\"296\">NMT 1ppm<\/td>\n<\/tr>\n<tr>\n<td width=\"251\">\u6c5e\uff08Hg\uff09<\/td>\n<td width=\"296\">NMT 0.1ppm<\/td>\n<\/tr>\n<tr>\n<td width=\"251\">\u94c5 (Pb)<\/td>\n<td width=\"296\">NMT 3ppm<\/td>\n<\/tr>\n<tr>\n<td width=\"251\">\u63d0\u53d6\u6eb6\u5242<\/td>\n<td width=\"296\">\u8c37\u7269\u9152\u7cbe\/\u6c34<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p><img decoding=\"async\" src=\"\/wp-content\/uploads\/replace\/dfb2a3e828003c30d1dd625237ced113.jpeg\" alt=\"\u6800\u5b50\u82b1\u7d2b\" title=\"Gardenia purple\u63d2\u56fe2\" \/><\/p>\n<ol>Gardenia purple as a nutritional colorant used in food can significantly improve the appearance and color of food.<\/p>\n<li>Gardenia purple is also used in Chinese medicine.<\/li>\n<li>It is also used in drinks, color effect is good, bright color.
