摘　　要：为富硒大豆产品的综合开发利用提供依据,采用氢化物-原子荧光光度法测定不同硒含量大豆制作豆腐乳过程中各阶段产物及其制品的硒含量。结果表明:当大豆中硒的含量分别为1.253mg/kg、0.015mg/kg、2.495 mg/kg时,生产的豆腐乳、豆渣、豆腐和黄浆水中的硒含量分别为0.246 mg/kg、0.236mg/kg、0.291mg/kg和0.347mg/kg;0.003mg/kg、0.003mg/kg、0.003mg/kg和0.005mg/kg;0.534mg/kg、0.526mg/kg、0.553mg/kg和0.622mg/kg。生产豆腐乳时,硒的回收率分别是80.71%、88.34%和88.80%;硒含量在黄浆水、豆渣和豆腐乳中占硒总回收的比例分别为20.22%~25.53%、27.35%~30.13%和44.36%~52.43%。In order to provide the basis for comprehensive exploitation and utilization of Se-enriched soybean products,hydride generation-atomic fluorescence spectrophotometry was employed to determine Se content in fermented bean curd and product during the processing process of fermented bean curd with soybean containing various Se concentration.Results: When Se concentration was 1.253 mg/kg in soybean,the Se contents in produced fermented bean curd,bean dregs,bean curd and yellow serofluid were respectively 0.246 mg/kg,0.236 mg/kg,0.291 mg/kg and 0.347 mg/kg,and they were 0.003 mg/kg,0.003 mg/kg,0.003 mg/kg and 0.005 mg/kg when Se concentration was 0.015 mg/kg in soybean,and 0.534 mg/kg,0.526 mg/kg,0.553 mg/kg and 0.622 mg/kg when Se concentration was 2.495 mg/kg in soybean.The recovery of Se was 80.71%,88.34%and 88.80%in production of fermented bean curd.The proportion of Se content in total Se recovery in yellow serofluid,bean dreg and fermented bean curd was 20.22%-25.53%,27.35%-30.13%and 44.36%-52.43%separately.
