中文摘要: 以干苞菠萝蜜干果粉为原料,无水乙醇为浸提剂,提取菠萝蜜芳香浸膏并进行风味分析。采用Box-Behnken响应面优化浸提工艺,采用气质联用(Gas chromatography-mass spectrometry,GC-MS)鉴定挥发性成分。菠萝蜜芳香浸膏最佳提取条件为:菠萝蜜果粉与无水乙醇料液比为1∶42(g/mL),于70℃下浸提2 h,此条件下浸膏最大得率为42.81%,与预测值43.00%较为接近;芳香浸膏经GC-MS检测出36种风味物质,其主要芳香成分有4-(1-甲基乙基)苯甲醇(6.22%)、1,6-二甲基十氢化萘(15.06%)和 5-[N(2)-(异亚丙基丙酮)]咪唑(14.58%)。本工艺制得的浸膏风味良好,在食品香精及烟用香精行业具有广阔的市场前景。
Abstract:By using dried jackfruit as raw material and anhydrous ethanol as extractant,jackfruit aroma extract was extracted and the flavor analysis was carried out.The extraction process was optimized by Box-Behnken response surface,and the volatile components were identified by GC/MS.The optimum extraction conditions were as follows:the ratio of jackfruit fruit powder to anhydrous ethanol was 1∶42(g/mL),and extracted at 70℃for 2 h,under this condition,the maximum yield of extract was 42.81%,which was close to the predicted value of 43.00%;There were 36 kinds of flavor substances were detected in aroma extract by GC-MS,and the main aroma components were 4-(1-methylethyl)benzyl alcohol(6.22%),1,6-dimethyl(15.06%)and 5-[N(2)-(isopropylideneacetone)]imidazole (14.58%).The extract made in this process has a good flavor and has a broad market prospect in the food flavor and tobacco flavor industry.
