    為了提高對蘋果多酚的分離效率，以實現(xiàn)工業(yè)化生產(chǎn),，在單因素試驗得出的工藝基礎上,，采用響應曲面法建立了NKA—9大孔樹脂對蘋果多酚(AP)動態(tài)吸附和動態(tài)解吸的二次多項數(shù)學模型，驗證了模型的有效性,?？疾炝松蠘铀俾省右嘿|(zhì)量濃度,、樣液pH值對AP動態(tài)吸附量以及洗脫速率,、洗脫劑體積分數(shù)和洗脫劑用量對AP動態(tài)解吸的影響。優(yōu)化出NKA—9大孔樹脂的動態(tài)吸附工藝參數(shù)為：上樣速率1.10mL/min,，樣液質(zhì)量濃度2.50mg/mL,，pH值4.83；動態(tài)解吸工藝參數(shù)為：洗脫速率0.61mL/min,，洗脫劑體積分數(shù)59.48％,，洗脫劑用量

    Abstract:

    125.73mL。In order to improve extract efficiency of apple polyphenols, the dynamic law of apple polyphenols (AP) adsorption and desorption to NKA—9 macroporous resin was researched to establish a mathematic model. The Response Surface Methodology(RSM) was used to investigate the effects of feeding rate, sample concentration and pH on the adsorption properties of macroporous resin and the effects of flow rate, eluent concentration and elution volume on the desorption properties of macroporous resin for apple polyphenols. The results showed that the optimum adsorption conditions were the feeding rate of 1.10mL/min, sample concentration of 2.50mg/mL, pH 4.83. The optimum desorption parameters were the flow rate 0.61mL/min, eluent concentration 59.48%, elution volume 125.73mL. In conclusion, the NKA—9 macroporous resin can be used as the best material to extract the apple polyphenols.
