    为充分利用蜂花粉资源，采用酸提工艺提取蜂花粉可溶性膳食纤维，利用单因素试验和响应面优化法对液料比、浸提pH值、浸提温度、浸提时间工艺条件进行分析与优化，并测定蜂花粉可溶性膳食纤维的理化指标。结果表明，蜂花粉可溶性膳食纤维酸提最优工艺为：液料比10.8∶1(mL/g)、浸提pH值4.3、浸提温度50℃、浸提时间1.9 h，在此工艺条件下蜂花粉可溶性膳食纤维得率为7.31%，膨胀力0.87 mL/g、持水力1.33 g/g、水溶性84.78%。

    〔Abstract〕In order to fully utilize bee pollen resource，the soluble dietary fiber from bee pollen was extracted using acid extraction process.The process conditions of liquid-to-solid，extraction pH，extraction temperature，extraction time were analyzed and optimized by single-factor experiment and response surface methodology.The physicochemical properties of bee pollen soluble dietary fiber were measured.The optimal extraction conditions were determined as follows 10.8:1(mL/g)of liquid-to-solid，pH4.3，extraction temperature 50℃，extraction time 1.9 h.Under the conditions，the yield of bee pollen soluble dietary fiber was 7.31%，swelling capacity was 0.87 mL/g，water holding capacity was 1.33 g/g ......
