| 摘 要： | 澳洲青苹是高酸品种之一，文中对澳洲青苹的主要加工特性进行了研究，并与其他苹果加工品种的同类指标作了比较。结果表明，澳洲青苹的硬度为8.106kg／cm~2，出汁率75.702％，固形物含量13.62％，有机酸含量0.655％，Vc含量87.2mg／kg，而引起果汁酶促褐变的主要底物——多酚类物质(以绿原酸为主)为61.82mg／L。与常用加工品种相比，其各项指标更符合果汁加工的要求。

| Abstract: | The high acidity apple is very unique in apple juice processing industry. And Granny Smith is one of high acidity apple breeds. In this paper, the main factors of Granny Smith in processing, and comparison with the other breeds were studied. The results showed that the reigidity in Granny Smith is 8.106kg/cm~2, the juice extracting rate during the processing is 75.702%, and the content of soluble solids is 13.62 %, the organic acid is 0.655%, Vc is 87.2mg/kg, and phenolic compounds (counted as chlorogenic acid), which may cause the juice enzymatic browning, is 61.82mg/L. Compared with other breeds, Granny Smith is much suitable for industrial processing. |
