Study on the preparation and flavoring effect of cigarette flavor from black tea dust based on Maillard reaction
In order to prepare a sweet flavor for tobacco,the enzymatic hydrolysis conditions were optimized by single factor test and orthogonal test with Qimen black tea powder as raw material. The caffeine in the enzymatic hydrolysate was removed by montmorillonite adsorption method. The Maillard reaction was carried out with the content of heterocyclic compounds such as furan,pyrrole and pyrazine as the index. The reaction conditions were optimized by single factor test and response surface test. The aroma components of Maillard reaction spices under the optimal conditions were analyzed by GC-MS,and the spices were used for cigarette flavoring. The results showed that:1) The optimal enzymatic hydrolysis conditions were as follows:enzymatic hydrolysis time 7 h,enzyme addition amount 2.0%,and enzymatic hydrolysis temperature 48 ℃.Under these conditions,the reducing sugar content of the experimental group increased by 38.35% compared with the blank control group. 2) The caffeine removal rate of the enzymatic hydrolysate adsorbed by montmorillonite was as high as 85.88%,and the flavoring effect of the enzymatic hydrolysate was improved after the removal of caffeine. The optimal conditions for the Maillard reaction were as follows:the reaction temperature was 113 ℃,the reaction time was 95 min,the initial pH value was 8.4,and the molar ratio of ribose to proline was 1∶1. 3) A total of 50 substances were identified in the flavor prepared under the optimal conditions. Compared with the Maillard reaction flavor without ribose and proline,the content of coniferyl alcohol,phenylethyl alcohol,linalool oxide and other substances in the alcohols increased significantly.The new ketones were furanone,pyranone,pyrrolone and enolone.4) The flavoring effect of the flavor cigarette prepared under the optimal conditions was better,which could improve the aroma of the cigarette,improve the coordination,and endow the cigarette with burnt,sweet and baking flavor.
