【摘要】 以小袋气调、大帐气调及自然冷藏的元帅系苹果为试材,采用气相色谱法(GC)分析了贮藏期间果肉中芳香物质含量变化,结果表明:①自然冷藏时,‘红星’苹果贮藏初期乙醛、因醇及乙酸乙酯含量低,60天时形成高峰,其后持续下降,呈跃变型;②小袋气调时‘红星’苹果乙醛含量低于短枝型品种‘新红星’及‘首红’,而乙酸乙酯含量高于短枝品种;③小袋气调时,‘红星’苹果测出了13种四大类芳香物质,其中醇类和酯类物质有明显高峰期,醛类持续上升,酮类则无显著差异。小袋简易气调的芳香物质总量在90天时最高,大帐气调则在120天出现芳香物质高峰期。更多还原

【Abstract】 Delicious apple fruit were stored at 0-1℃ for 120 days in CA, simple CA (SCA) and cool storage (CS) condition. The contents of aroma volatites in the stored fruit was measured by gas chromatography during storage time. The results showed that:①In CS condition, the contents of acetaldshyde, ethanol and ethyl acetate in flesh of ’Starking’ fruit increased gradually,reached their peaks at 60 days, then declined from 60 to 120 days. However,in SCA condition,the mean contents of ethanol was significantly higher at 90 and 120 days. ②The content of acetaldehyde in non spur type ’Starking’ fruit in SCA condition was lower than that of spur type ’Starkrimson’, ’Redchief’ and ’Ultrared Del’, but ethanol and ethyl acetate contents in ’Starking’ fruit was higher than that of spur type varieties at 90 days in storage.③ ’Starking’ fruit in SCA condition had 13 kinds of volatile arome substances, including ketone, aldehyde, alcohol and easter. From 0 to 120 days in storage, alcohol and easter produced their peaks, ketone changed smoothly,but aldehyde increased conteniously. Fruit soluble solid content did not significantly decreased at 90 days in SCA storage. Meanwhile, the peak of total aroma volatites appeared, but the peak of CA treatment delayed to 120 days.更多还原
