宝泉大豆酱及农家酱香气成分的比较分析
目的  比较分析宝泉大豆酱和农家酱香气成分的差异。方法  利用顶空固相微萃取法和气相色谱-质谱联用技术, 对成品宝泉大豆酱及农家酱的挥发性成分进行分析, 并利用内标法计算各组份含量。结果  在宝泉大豆酱中和农家酱中均检出42种挥发性成分, 总含量分别为939.19、251.41 ng/g, 其中20种挥发性成分为其共有的。挥发性成分以酯类和醇类含量最高, 宝泉大豆酱中主要的酯和醇为亚油酸乙酯(387.05 ng/g)、棕榈酸乙酯(207.46 ng/g)和苯乙醇(25.05 ng/g); 农家酱中主要为亚油酸乙酯(87.80 ng/g)、油酸乙酯(41.21 ng/g)和2,3-丁二醇(14.19 ng/g), 这些醇酯类化合物种类和含量的不同, 造成了这2种大豆酱的香气存在较大的差异。结论  综合气质和感官评价结果表明, 宝泉大豆酱的香气品质较优于农家酱, 更符合东北人对大豆酱的要求。

Objective  To compare the differences of aroma components in Baoquan soybean sauce and village soybean sauce. Methods  Aroma components of Baoquan soybean paste and village soybean paste were analyzed by headspace solid phase microextraction and gas chromatography-mass spectrometry technology, and the component contents were calculated by internal standard method. Results  The results indicated that 42 kinds of aroma composition were detected in the Baoquan soybean sauce and village soybean sauce, and the total contents were 939.19 ng/g and 251.41 ng/g, respectively, and 20 kinds of them were simultaneously found in the Baoquan soybean sauce and village soybean sauce. The main esters and alcohols in Baoquan soybean sauce were ethyl linoleate (387.05 ng/g), ethyl palmitate (207.46 ng/g) and ethanol (25.05 ng/g). The main esters and alcohols in village soybean paste were ethyl linoleate (87.80 ng/g), ethyl oleate (41.21 ng/g) and 2,3-butanediol (14.19 ng/g). The different types and content of alcohol and ester, resulted in the differences of aroma components between Baoquan soy sauce and village soy sauce. Conclusion  According to the results of chromatography-mass spectrometry and sensory evaluation of comprehensive gas chromatography, the aroma quality of Baoquan soybean paste is better than village soybean paste, which meet the requirements of soybean paste of northeast residents.
