This study deals with the characterization of the phytochemical profiles and antioxidant activities of cv. Caner pomegranate () juices obtained from three different juice extraction methods including halved pomegranate (HPJ), arils (AJ), and macerated arils (MAJ) extraction for the first time. It was found that the type of the juice extraction process had substantial effects on the volatiles, anthocyanin compositions, and antioxidant activities of the samples. Results showed that the AJ sample (593 mg L) had more anthocyanin compounds followed by HPJ (555 mg L) and MAJ (408 mg L) samples. GC-MS analysis revealed a total of 34 volatile compounds. The highest number of volatiles was found in the MAJ sample (1872 µg L); thus, the aril maceration process played an important role in increasing the volatiles as compared to the HPJ (751.8 µg L) and AJ (710.7 µg L) samples. Sensory analysis showed that the HPJ sample was the most preferred and its general impression was higher as compared to the AJ and MAJ samples. The findings of this study elucidated that the juice extraction technique had a significant influence on the phytochemical profiles, sensory quality, and antioxidant activity of pomegranate juices.
本研究首次对通过三种不同榨汁方法(包括对半切开的石榴榨汁(HPJ)、石榴籽榨汁(AJ)和浸泡石榴籽榨汁(MAJ))获得的卡纳石榴()汁的植物化学特征和抗氧化活性进行了表征。结果发现,榨汁工艺类型对样品的挥发性成分、花青素组成和抗氧化活性有显著影响。结果表明,AJ样品(593毫克/升)的花青素化合物含量更高,其次是HPJ样品(555毫克/升)和MAJ样品(408毫克/升)。气相色谱-质谱联用(GC-MS)分析共鉴定出34种挥发性化合物。MAJ样品中挥发性化合物的数量最多(1872微克/升);因此,与HPJ样品(751.8微克/升)和AJ样品(710.7微克/升)相比,石榴籽浸泡过程在增加挥发性成分方面发挥了重要作用。感官分析表明,HPJ样品最受青睐,与AJ和MAJ样品相比,其总体评价更高。本研究结果表明,榨汁技术对石榴汁的植物化学特征、感官品质和抗氧化活性有显著影响。
