摘要
采用打顶产生的大田废弃烟叶提取浸膏,对浸膏进行美拉德反应增香,从而制备特色烟用香料。以感官评价为评价指标,利用单因素和正交试验对反应温度、pH和加热时间进行优化,得到美拉德反应制备香料的最优条件为反应温度120℃、pH=12、加热时间180 min。通过对香料进行GC/MS分析,鉴定出29种成分,其中吡嗪类4种,醇类6种,酯类3种,醛类2种,酮类2种,烯类2种,胺类1种,香味物质如巨豆三烯酮、苄醇、二氢猕猴桃内酯、香橙烯等成分,是关键的致香物质。
The waste tobacco leaves produced after topping in the field was used to obtain the extract,and the extract flavor was improved by Maillard reaction and the special tobacco flavor was prepared. Using sensory evaluation as the evaluation index,the reaction temperature,pH and heating time were optimized by single factor and orthogonal methods. The optimal conditions for preparation of special tobacco flavor were as following reaction temperature 120℃,pH 12,heating time 180 min. Through GC/MS analysis,29 kinds of compounds were identified,including four pyrazines,six alcohols,three lipids,two aldehydes,two ketones,two alkenes,one amine. Aroma substances such as megastigmatrienone,benzyl alcohol,dihydroactinidiolide,aromadendrene and other components,were the key aroma substances.
