摘要: 研究不同贮藏温度(0、5、10℃和室温)对鲜食石榴籽粒贮藏品质、活性成分及抗氧化能力的影响。结果表明,与10℃和室温贮藏条件相比,0℃和5℃能减缓石榴籽粒的呼吸速率、抑制相对电导率和质量损失率的升高、提高抗氧化活性,大大延长了商品货架期。其中,0℃更好地保持了可溶性固形物含量和花色苷稳定性,并能保持更好的品质和货架期,因此,0℃可作为鲜食石榴籽粒最适宜的贮藏温度。

Abstract: The overall quality, functional components and antioxidant activity of ready-to-eat pomegranate seeds stored at different temperatures (0, 5, 10 ℃ and room temperature) were investigated. The results indicated that lower temperatures (0 ℃ and 5 ℃) reduced the respiration rate, maintained a significantly lower relative conductivity and weight loss rate, improved the antioxidant activity and prolonged the shelf-life of pomegranate seeds when compared with those stored at 10 ℃ and room temperature. At the end of storage, ready-to-eat pomegranate seeds stored at 0 ℃ exhibited higher total soluble solids and anthocyanins than those stored at 5 ℃ and 10 ℃ as well as room temperature. Our findings suggest that ready-toeat pomegranate seeds should be stored at 0 ℃ to maintain optimal quality and maximal shelf life.

Key words: temperature, ready-to-eat, pomegranate seeds, quality, shelf-life, antioxidant activity
