- 摘要:
- 以野生稠李果实为原料，将色素溶液进行1∶20的比例稀释，放在400～700 nm的波长范围内扫描，表明532 nm处为最大。通过乙醇浓度、温度、物料固液比、提取时间，进行四因素三水平正交实验，确定野生稠李色素最佳提取工艺。结果表明：稠李色素最佳的提取条件为乙醇浓度30%，提取温度75℃，固液比为1∶10，提取时间90 min。
- Abstract:
- Taking the fruits of wild Padus racemosa as test materials，the pigment solution were diluted as the ratio of 1∶20 and scanned in the range of 400～700 nm wavelength，in 532 nm had the biggest absorbance ratio.By orthogonal test of four factors that were ethanol concentration，temperature，liquid-solid ratio，extraction time，the best pigment extraction conditions from Padus racemosa Gilib.were determined.The results showed that the best pigment extraction conditions were 30% ethanol，extraction temperature 75℃，the liquid-solid ratio 1∶10，extraction time 90 min.
