【摘要】 为探究石榴籽对石榴汁挥发性风味物质的影响，以新疆策勒酸石榴为原料，采用固相微萃取-气相色谱-质谱联用（Solid phase microextraction-gas chromatography-mass spectrometry,SPME-GC-MS）仪对石榴汁、石榴籽和石榴果浆的挥发性成分进行比较分析。结果表明，新鲜石榴汁共检测出49种挥发性化合物，主要挥发性成分包括酸类9种、醇类11种和醛类14种，特点是具有更多的花香、果香和甜味；新鲜石榴籽共检测出33种挥发性化合物，主要挥发性成分包括醛类10种、醇类8种和酸类4种，特点是除了一些花香、果香和甜味，还增添了一些脂肪味和蘑菇味；而添加石榴籽的石榴果浆共检测出44种挥发性化合物，主要挥发性成分包括醇类7种、醛类10种和酸类8种，除了两个原料的香味特点，果味、甜味、青香、焦糖和霉味都增强。3种不同原料的脂肪酸含量和数量存在较大差异，对产品的品质和风味可能会造成影响，石榴籽的加入使整体产品风味更为复杂，产品的质量和贮藏时间也可能会受到影响。该研究结果为新疆地区策勒酸石榴品种的品质评价和产品开发提供了参考依据。更多还原

【Abstract】 In order to investigate the effect of pomegranate seeds on the volatile flavor compounds in pomegranate juice,using Xinjiang Zele acid pomegranate as the raw material,the volatile components of pomegranate juice,pomegranate seeds,and pomegranate pulp were comparatively analyzed by solid phase microextraction gas chromatographymass spectrometry(SPME-GC-MS).The results showed that a total of 49 volatile compounds were detected in fresh pomegranate juice,the main volatile components included 9 acids,11 alcohols,and 14 aldehydes,characterized by more floral,fruity,and sweet flavors.A total of 33 volatile compounds were detected in fresh pomegranate seeds,the main volatile components included 10 aldehydes,8 alcohols,and 4 acids,characterized by additional fat and mushroom flavors besides some floral,fruity,and sweet flavors.A total of 44 volatile compounds were detected in the pomegranate pulp with added pomegranate seeds,there were the main volatile components of 7 alcohols,10 aldehydes,and8 acids.In addition to the aroma characteristics of the two raw materials,the fruity,sweet,green,caramel,and moldy flavors were significantly enhanced.There were significant differences in the content and quantity of fatty acid chains among the three different raw materials,which may affect the quality and flavor of the product.The addition of pomegranate seeds could make the overall flavor of the product more complex,and the quality and storage time of the product might also be affected.The research results can provide a reference for the quality evaluation and product research of Cele acid pomegranate varieties in Xinjiang.更多还原
