摘要: 采用热风干燥、真空干燥、真空冷冻干燥方式处理救心菜,测定救心菜粉色泽与维生素C(VC)、总酚、叶绿素、蛋白质、总黄酮及齐墩果酸含量,研究不同干燥方式对救心菜粉营养及功能成分的影响。结果表明,真空冷冻干燥制得的救心菜粉色泽,Vc、总酚、叶绿素、蛋白质、总黄酮、齐墩果酸含量均显著(P<0.05)优于其他干燥方式。热风干燥制得的救心菜粉蛋白质、齐墩果酸含量显著(P<0.05)高于真空干燥。综合考虑救心菜粉的营养品质及功能价值,真空冷冻干燥方式效果较好。

Abstract: In the present study, three drying methods, i.e. hot air, vacuum, vacuum freezing, were applied to deal with Sedum aizoon. The color, and contents of vitamin C (VC), total phenols, chlorophyll, protein, total flavonoids and oleanolic acid of the processed Sedum aizoon powder were determined to explore the effects of different drying methods on nutrition and functional components. It was shown that color, and the contents of Vc, total phenols, chlorophyll, protein, total flavonoids and oleanolic acid in the produced powder by vacuum freeze were significantly (P<0.05) superior than those in other products. Contents of protein and oleanolic acid in the powder produced by hot air were significantly (P<0.05) higher than those produced by vacuum. Based on the nutritional quality and functional value of Sedum aizoon powder, it was suggested that vacuum freeze was the optimal drying method.
