优化Fe-CA仿酶合成工艺研究
Optimization of the synthesis process of Fe-CA biomimetic enzyme
摘要
Abstract
In order to reduce the lignin content in cut stems,to improve the quality of cut stems and to increase their proportion in cigarette blends,single factor experiments were conducted to study the effects of four factors involved in synthesis of Fe-CA biomimetic (molar ratio,reaction temperature,reaction time,and pH).The synthesis process of Fe-CA biomimetic was optimized by orthogonal test,the cut stems were analyzed by scanning electron microscope before and after Fe-CA biomimetic treatment,and the sensory quality of cigarettes made of the treated and untreated cut stems was panel tested,separately.The results showed that:under the optimum synthesis conditions,n (Fe2 +):n (citric acid) 11,reaction temperature 60 ℃,reaction time 40 min,and pH 6.0,the synthesis rate is 82.1％;after the Fe-CA biomimetic treatment of the cut stems,the content of lignin in cut stems fell from 3.49％ to 1.60％,the removal rate reached 54.15％,and the surface of the cut stems was smoother with less burrs;compared with the control,the aroma quality,aroma quantity of the test cigarette smoke were improved,the levels of offensive odor and irritation were reduced,and the quality of the cut stems was enhanced.关键词
