摘　　要：以"红富士"苹果为试材,以水杨酸、氯化钙、茉莉酸甲酯复配配制保鲜液,室温下将"红富士"苹果进行涂膜处理,研究了该保鲜液对苹果贮藏期间多酚含量的影响。结果表明:与对照组相比,试验组表现出了较好的保鲜效果。200μg·mL^(-1)水杨酸、2%CaCl2和0.05μmol·mL^(-1)茉莉酸甲酯复配溶液保鲜效果最好;试验中备选的5种用于吸附苹果多酚的大孔树脂中,HPD-100的吸附效果最好;采用该树脂进行多酚吸附的最佳工艺条件是流速为2.5BV·h-1,吸附浓度为1.12mg·mL^(-1),pH 2.13。采用该工艺,可使吸附率上升至95.273 2%。The ＇ Fuji＇ apple was used as material, salicylic acid, calcium chloride, methyl jasmonate complex configuration preservation solution were conducted, the ＇ Fuji＇ apples were coated at room temperature, the preservation was studied during storage of apple polyphenol content impact. The results showed that the experimental group showed better preservation effect compared with the control group; the solution made up of 200 μg · mL^-1 SA, 2% CaCl2 and 0. 05 μmol· mL^- 1 MeJA exhibited the most flesh-keeping effect. The optimum apple polyphenols purification conditions were as follows. HPD-100 macroporous resin,2. 5 BV · h^-1 flow rate, 1.12 mg · mL ^-1 concentration of apple polyphenol adsorption concentration,and pH 2. 13. Under these conditions, the adsorption rate could increase to 95. 273 2 %. To sum up, compared with control group, the treatment groups all indicated better fresh-keeping effect.
