摘要:以9种苹果鲜榨汁为材料,通过理化指标测定和感官评价,研究鲜榨苹果汁理化特性和感官品质之间的相
关性。结果表明:1)部分理化指标之间具有显著的相关性;2)理化指标与感官特性之间存在显著的相关性:苹果香
与pH值、可滴定酸含量有显著的相关性;清香与色值、总糖含量呈正相关;涩味与可滴定酸含量、多酚含量、缓
冲容量成正相关,与pH值、糖酸比、固酸比呈现显著的负相关;酸味与pH值、总糖含量、可滴定酸含量、缓冲容
量、糖酸比、固酸比有相关性;甜味与可溶性固形物含量(SSC)、可滴定酸含量、缓冲容量、固酸比有相关性;3)
通过回归分析建立的苹果汁滋味评价模型,回归方程显著,说明鲜榨苹果汁理化特性和感官品质具有很好的相关
性,可以实现理化指标对感官品质的预测分析。

Abstract:The aim of the present study was to explore the correlations between physico-chemical characteristics and
sensory measures of fresh apple juice from 9 varieties. The results showed that: 1) there were significant correlations among
partial physico-chemical characteristics of apple juice; 2) significant correlations were found between physicochemical
characteristics and sensory measures of apple juice. The fruity aroma of apple juice was significantly correlated with its pH
and
