摘要:

采用固相微萃取- 气相色谱- 质谱法对伏令夏橙汁加工过程中5 个关键点样品的主要香气成分进行分析,共鉴定出50 种香气成分,主要为柠檬烯(84.79%~86.92%)、β- 月桂烯(3.87%~5.83%)、α- 蒎烯(1.03%~2.05%)、芳樟醇(0.02%~1.72%)、葵醛(0.15%~0.28%)、辛醛(0.03%~0.52%)和丁酸乙酯(0.12%~0.44%)等。加工过程对夏橙汁香气成分种类和含量有重要影响,5 个样品香气成分种类分别为38 种、36 种、31 种、30 种和20 种。精滤后烃类相对含量增加2.01%,醇类物质下降2.00%;脱气后烃类下降0.95%,醇类下降0.15%;灭菌后香气成分与脱气后相近;浓缩还原对香气影响最大,烃类和醇类比精滤后橙汁分别降低3.85%、1.16%。

Abstract:

The aromatic components in Valencia orange juice from five processing control points were analyzed and identified by solid phase micro extraction-gas chromatography-mass spectrometry (SPME-GC-MS). Totally 50 aromatic components were found, and main components were as follows: limonene (84.79%-86.92%), β -myrcene (3.87%- 5.83%), α - pinene (1.03%-2.05%), linalool (0.02%-1.72%), decanal (0.15%-0.28%), nonanal (0.03%-0.52%) and ethyl butyrate (0.12%-0.44%). Processing had important influence on the varieties and contents of aromatic components, and the varieties in 5 samples were 38, 36, 31, 30 and 20, respectively. After the refining filtration, the contents of hydrocarbons increased 2.01%, and the contents of alcohols decreased by 2.00%. After deaeration, the contents of hydrocarbons and alcohols decreased by 0.95% and 0.15%, respectively. After pasteurization, the juice had the similar aromatic constituents with those of the deaerated juice. The contents of hydrocarbons and alcohols decreased by 3.85% and 1.16% respectively after reconstituting from concentrate.
