对山东沂源、济宁两个产区巨峰葡萄的香气物质进行分析.结果表明,两个产区均检测到7大类香气,沂源产区检出44种香气成分,济宁产区检出47种香气成分,香气总量分别为1845.46 ng/g、1326.50 ng/g,酯类物质含量最高,分别占其香气总量的82.94%、74.70%.主要香气成分为(E)-2-己烯醇、2-己烯醛、乙酸乙酯、酞酸二乙酯、香叶基丙酮和二苯并呋喃,其中乙酸乙酯含量最高,2-己烯醛、丁酸乙酯和酞酸二乙酯含量也较高.沂源产区巨峰葡萄中酯类和醛类含量高于济宁产区,而醇类、烃类和杂环类含量低于济宁产区.己酸甲酯、(E)-2-戊烯酸乙酯、草酸二异丁酯等为沂源产区巨峰特有香气;(E)-3-乙基己烯醇、3,5-二叔丁基-4-羟基苯甲醛、2-甲基-2-丁烯酸乙酯、甲酸己酯、邻苯二甲酸二丁酯、苯甲酸苄酯等为济宁产区巨峰特有成分.产区因素影响巨峰葡萄香气物质的组成和含量,沂源产区巨峰葡萄香气更浓郁.

The aroma components in Kyoho grapes from Yiyuan and Jining areas of Shandong province were investigated. The results showed that 7 types of aroma were found in both Yiyuan and Jining. 44 kinds of aroma components from Yiyuan region and 47 kinds from Jining were detected with the total contents of 1845.46 ng/g and 1326.50 ng/g respectively. Esters took the first place in Kyoho grapes. (E)-2-hexen-1-ol, 2-hexenal, ethyl acetate, diethyl phthalate, (E)-6,10-dimethyl-5,9-undecadien-2-one and dibenzofuran were detected as the principal components, while ethyl acetate, 2-hexenal, ethyl butyrate and diethyl phthalate were the most. With methyl hexanoate, (E)-Ethyl-2-pentenoate, Bis(2-methylpropyl) oxalate as its special aroma components, Kyoho grapes from Yiyuan region had higher contents of esters and aldehydes, while alcohols, hydrocarbons and heterocycles were less. (E)-3-ethyl-hexenol, 3,5-ditert-butyl-4-hydroxybenzaldehyde, 2-methyl-ethyl trans-2-butenoate, hexyl formate, dibutyl phthalate, benzyl benzoate were special components in Kyoho grape from Jining region. Different regions could influence the aroma composition and content obviously, and Kyoho grape from Yiyuan showed more intense aroma.
