富硒食醋熏醅工艺研究

[目的]优化富硒食醋的熏醅工艺条件.[方法]以富硒农作物为原料,采用传统固态发酵法酿造富硒食醋,通过正交试验优化熏醅工艺.[结果]试验表明,富硒食醋最佳的熏醅工艺条件为：熏醅温度110℃、24h倒缸一次、熏制5.5d,结果测定食醋中硒含量为2.49 mg/kg,感官评分为9.49分,不挥发酸为71 g/kg.[结论]研究可为生产开发功能保健型的富硒食醋提供一定的参考依据.

Research on the Smoking Solid-substrate Fermentation Processing of Selenium Enriched Vinegar

[Objective] To optimize smoking solid-substrate fermentation processing conditions of selenium enriched virnegar.[Method] With selenium enriched crops as raw materials,using traditional solid-state fermentation method for brewing vinegar enriched selenium,the technique was optimized through orthogonal test.[Result] The results showed that the optimal conditions are：fumigating temperature 110 ℃,24 h inverted cylinder once,smoked 5.5 d.The result of fumigating selenium content was 2.49 mg/kg,the sensory score was 9.49 points,nonvolatile acid was 71 g/kg.[Conclusion] The study can provide a certain reference basis for production of selenium enriched vinegar.
