摘　　要：以杏渣为原料,采用化学法水解淀粉、蛋白质、脂肪,提取杏渣中不溶性膳食纤维。研究表明,碱作用提取的最佳工艺条件为:pH值为12,温度为60℃,时间为80 min,固液比为1∶15;酸作用提取的最佳工艺条件为:pH值为2.0,时间100 min,温度50℃,固液比1∶15;不溶性膳食纤维得率为69.25%。This paper introduced apricot dregs as materials, chemistry method was adopt to hydrolyze amylum, protein, fat and infusibility meal fiber in apricot dregs. The research indicated：the effect of alkali distilled optimum process condition：pH was 12,temperature was 60℃ ,time was 80rain,the ratio of solid and fluid was 1 ： 15, the effect of acid distilled optimal process condition p H was 2.0, time was 100min, temperature was 50 ℃ ,the ratio of solid and fluid was 1： 15. Under the above conditions,the rate of infusibility meal fiber was 69.25 %.
