摘要
测定了白凤桃(PrunuspersicaBatschcv.Hakuho)果实中果汁的糖、酸、氨基酸、挥发性香气成分以及与其相对应的甜味、酸味、香气等风味特性之间的相关关系。结果表明:甜味与可溶性固形物含量呈较高的正相关;酸味与滴定酸呈高的正相关,而与挥发性香气物质十内酯、八内酯、己内酯、可溶性固形物含量呈较高的负相关;3种内酯物质与具有桃芳香风味的特性呈正相关,而与具青气风味特性呈负相关。以风味评定(综合评定)为因变量Y,各种测定成分为主变量X,逐步回归法分析的结果表明,影响桃风味的成分有可溶性固形物含量、滴定酸、十内酯、八内酯、反式-2-己烯醛。其中以酸度和十内酯物质含量的影响为最大。
