利用索氏提取和薄层色谱分离技术,从市售红曲红中得到1种含羟基红曲红色素.该红曲红色素水溶液与马铃薯淀粉、玉米淀粉、小麦淀粉、红薯淀粉所形成悬浮物,扫描电镜、偏光实验结果表明红曲红色素在淀粉颗粒表面发生了物理吸附,且吸附作用没有改变淀粉的内部结构.落射荧光实验表明该红曲红色素荧光颜色为黄色或绿色,热台实验表明该色素不适用于220℃的加工条件.
利用索氏提取和薄層色譜分離技術,從市售紅麯紅中得到1種含羥基紅麯紅色素.該紅麯紅色素水溶液與馬鈴藷澱粉、玉米澱粉、小麥澱粉、紅藷澱粉所形成懸浮物,掃描電鏡、偏光實驗結果錶明紅麯紅色素在澱粉顆粒錶麵髮生瞭物理吸附,且吸附作用沒有改變澱粉的內部結構.落射熒光實驗錶明該紅麯紅色素熒光顏色為黃色或綠色,熱檯實驗錶明該色素不適用于220℃的加工條件.

A kind of red monascus pigment containing hydroxyl group was gotten by Soxhlet extraction and TLC separation technology from a commercially available red Monascus. The suspended substance were formed in the red monascus pigment aqueous solution and potato starch, corn starch, wheat starch, sweet potato starch. The scanning electron microscopy, polarizing experimental results showed that red monascus pigment was adsorbed on the starch granule surface by physical adsorption , and the adsorption process did not change the internal structure of starch. The results of EPI-fluorescence experiments indicated that the red monascus pigment fluorescence color was yellow or green , the results of hot stand experiments showed that the pigment must be used under to 220℃.
