摘要
Abstract
Almond shell is processing waste from the almond process and it was used as the raw material for extracting pigment and lignin with water/ethanol as extractant at 75 ℃ , 2 h, and the ratio of material to liquid was 1 g:15 mL. It was shown from the light stability results that the almond shell pigment was relatively stable in dark condition, but it was sensitive in the natural light and easily degradable. It was stable under 85 ℃ ,but the absorbance decreased obviously at 85 ℃. Sucrose and pH also influence the stability of pigment. In addition, Na+ ,K+ ,Ca2+ ,Mg2+ had little effect on the stability of almond shell pigment, but Cu2+ and Al3+ were effect on the pigment stability seriously. Oxidants were effect on stability of the pigment very much. Vc was little effect on the almond shell pigment. This research provides a reference for development and utilization of natural almond shell pigment.关键词
