Apples and apple-based products are particularly interesting due to being a good source of polyphenols in an everyday diet. Recently there has been increased interest in the preservation of traditional apple varieties due to studies that suggest that traditional apple varieties have a higher content of polyphenols and antioxidant activity compared to commercial varieties. This study shows that traditional apple varieties contain higher concentration of polyphenolic compounds than conventional ones, such as chlorogenic acid (1.29-456 mg/kg dw), catechin (0.70-312 mg/kg dw), epicatechin (1.75-244 mg/kg dw), procyanidin B1 + B2 (4.08-358 mg/kg dw) and quercetin-3-glucoside (0.96-231 mg/kg dw). This research underlies the great potential of traditional apple varieties as a source of natural antioxidants and polyphenolics.
苹果及苹果制品在日常饮食中是多酚的优质来源,因而格外引人关注。近期,由于研究表明传统苹果品种相较于商业品种含有更高的多酚含量和抗氧化活性,人们对传统苹果品种的保护兴趣日益浓厚。本研究表明,传统苹果品种所含的多酚类化合物浓度高于常规品种,如绿原酸(1.29 - 456毫克/千克干重)、儿茶素(0.70 - 312毫克/千克干重)、表儿茶素(1.75 - 244毫克/千克干重)、原花青素B1 + B2(4.08 - 358毫克/千克干重)和槲皮素-3-葡萄糖苷(0.96 - 231毫克/千克干重)。这项研究突显了传统苹果品种作为天然抗氧化剂和多酚来源的巨大潜力。
