探讨了不同加工方法、不同贮存条件及不同贮存时间对矮象草天然色素含量的影响.试验结果表明:矮象草叶粉含有较丰富的天然色素.经低温烘干处理后的叶黄素含量比高温烘干处理的高;无氧贮存比有氧贮存叶黄素含量高,损失率低,且差异极显著(P<0.01);随着贮存时间的延长,叶黄素的含量有所下降.

The influence of processing, storage conditions and storage times on the concentration of pigments in Pennisetum pttrpttreum was investigated. The results showed that there were plenty of pigments in leaf meal of P. Purpureum. After dried at a low temperature,concentration of xanthophyll was higher than at a high temperature. Loss of xanthophyll under an anerobic storage condition was lower than under an aerobic condition, concentration of xanthophyll was significant different (P<0. 01) between those two storage conditions. Concentration of xa,nthophyll declined with storage time extension.
