| 摘 要： | 果丹皮的色泽极易发生劣变。研究了传统工艺制作的果丹皮置于常温、常温+遮光、37℃+光照(2000lx)、37℃+遮光4种处理条件下的色泽变化情况。结果表明,温度越高、光照越强,L值越大,而a值、b值在常温、黑暗条件下显著高于其他处理条件,且各处理L,a,b值随处理时间无明显变化规律。

| Abstract: | The colour of hawkthorn sweeten roll will deteriorate easily after production.Room temperature,room temperature+unlightness,37 ℃+lightness(2 000 lx),37 ℃+unlightness(2 000 lx)effect on colour of hawkthorn sweeten roll were studied in this paper.The results showed that L-value would be higher after treated by high temperature and intensity light,while a-value and b-value would more higher than other treatments in room temperature and unlightness.At the same time,L-value,a-value and b-value have no relationship with time after treatment. |
