New early- to mid-season apple cultivars are being developed to help address warmer growing seasons due to climate change. Free sugars, organic acids, total phenolic content, total flavonoid content, antioxidant activity and phenolic composition were determined in the pulp and peel of six new and six traditional apple cultivars. In addition, the phenolic profiles of apple peels were characterized using high-resolution mass spectrometry. Forty-eight polyphenol compounds were identified, by accurate mass, in apple peel.
Compared to Fuji apples, a new apple cultivar, Decobell, contained 2.6- and 1.4-fold higher levels of the sum of individual polyphenol levels in the peel and the pulp, respectively. Decobell apples showed similar sugar-to-acid ratio (0.27) to Fuji apples (0.25).
The results indicate that the Decobell cultivar could have the best quality characteristics in terms of sugar-to-acid ratios and health-promoting activities due to the phenolic profiles. © 2019 Society of Chemical Industry.
为应对气候变化导致的生长季节变暖，新的早、中季苹果品种正在被开发。在果肉和果皮中测定了六个新的和六个传统苹果品种的游离糖、有机酸、总酚含量、总类黄酮含量、抗氧化活性和酚类组成。此外，还使用高分辨率质谱对苹果皮的酚类图谱进行了表征。通过精确质量，在苹果皮中鉴定出 48 种多酚化合物。
与富士苹果这一新的苹果品种相比，Decobell 品种果皮和果肉中单宁含量的总和分别高出 2.6 倍和 1.4 倍。Decobell 苹果的糖酸比（0.27）与富士苹果（0.25）相似。
由于酚类图谱，Decobell 品种的糖酸比和促进健康的活性可能具有最佳的品质特征。 © 2019 化学工业协会。
