    摘要:

    为了制备分离苹果渣中多酚的纳米材料,通过改变甲基丙烯酸、乙二醇二甲基丙烯酸酯、偶氮二异丁腈和乙腈用量的试验,研究不同条件下甲基丙烯酸纳米材料的成型,结合苹果渣多酚提取液中多酚吸附试验,确定最佳多酚吸附量的纳米材料制备工艺。结果表明,甲基丙烯酸纳米材料的最佳制备工艺参数为:甲基丙烯酸(MAA)2.5mmol、乙二醇二甲基丙烯酸酯(EDMA)2.5mmol、偶氮二异丁腈(AIBN)1.00mmol、乙腈20mL,该条件下制备的纳米材料对多酚吸附量为33.42mg/g,解吸率为61.13%。

    Abstract:

    China is the biggest concentrated apple juice producer in the world with a production of millions of tons of apple pomace every year. It is an important comprehensive utilizing approach by separating of polyphenols from apple pomace. A nano-material for adsorption of polyphenols from apple pomace was prepared. The moulding condition and preparation process of methylacrylic acid nano-materials was optimized by changing the dosage of methylacrylic acid(MAA), ethylene glycol dimethacrylate(EDMA), azodiisobutyronitrile(AIBN) and acetonitrile, using chemical precipitation method and field emission scanning electron microscopy, and conducting the experiments of adsorbing of polyphenols from apple pomace by the prepared nano-material, so as to provide reference for the comprehensive utilization of apple residue. The results showed that the best preparation condition of this material was methylacrylic acid of 2.5mmol, ethylene glycol dimethacrylate of 2.5mmol, azodiisobutyronitrile of 1.00mmol and acetonitrile of 20mL, under which the adsorption capacity of obtained nano-material to polyphenols could achieve to 33.42mg/g, and the desorption rate was 61.13% at the same time. 
