Influence of Variety on Total Polyphenols Content and Antioxidant Activity in Apple Fruits (Malus domestica Borkh.)

Recently, an increasing interest in fruits and vegetable eating has been noticed particular through epidemiological biochemical studies pointing to their health benefits for human health. Specifically, apples (Malus domestica Borkh.) are one of the most frequently consumed fruits. Therefore, current study aimed compare total polyphenols content (TPC) antioxidant activity (AA) apple from different columnar trees growing experimental conditions. For this purpose, 7 cultivars obtained Botanic Garden (Slovak University Agriculture, Slovakia; vegetative season 2019/2020) were analysed. Among them, four green-yellow cultivars: Golden Delicious, Granny Smith, Goldcats, Rondo; green cultivar with red spots: Kordona; cultivar: Redcats, pink Pompink, used. Method using Folin-Ciocalteu reagent was applied quantify TPC, radical scavenging samples measured 2,2-diphenyl-1-picrylhydrazyl (DPPH) scavengers. Total (mg GAE.g-1 dry weight) ranged 2.92 ±0.31 (cv. Pompink) 9.02 ±0.32 Smith), whereas statistically significant differences (p <0.05) recorded between all analysed except Rondo (5.07 ±0.44) Kordona (4.18 ±0.35) as compared Redcats (4.96 ±1.06) one. As lowest values AA observed Pompink (35.03 ±3.49 %) and, conversely, highest ones Smith (88.55 ±4.25 %). These results suggest that TPC strongly influenced depending on cultivars. From aspect, upon achievement survey, employing more samples, it will be possible create a comprehensive overview properties possibility application food industry develop innovative products added value.</p&gt
