Phenolic antioxidant profiles in the whole fruit, flesh and peel of apple cultivars grown in Lithuania

Determination of the Phenolic Composition and Antioxidant Activity of Pear Extracts

“…Therefore, the findings from this study on the antioxidant activity of pear extracts in vitro were compared with those obtained in studies on other plants belonging to the Rosaceae family. The total reducing activity in apple extract samples was established by the UV-VIS spectrophotometric FRAP method in vitro and averaged 117.13 mol/g DW [48], and it was by 3.2-5.0 times more potent than the reducing activity of pear fruit extract. Such differences could have been influenced by the differences in the qualitative and quantitative composition of pear and apple fruit, which was determined not only by different genus factors but also by various other factors (composition of the soil, the climaticmeteorological, cultivation, or storage conditions, orchard fertigation, etc.)…”

Effect of apple peel extract as natural antioxidant on lipid and protein oxidation of rainbow trout (Oncorhynchus mykiss) mince

“…Apple peel, a by-product of apple processing, has previously been shown to possess diverse biological properties, making it suitable as a functional ingredient (Wolfe and Liu 2003). Flavanols, hydroxycinnamates, dihydrochalcones, flavonols, and anthocyanins are the main polyphenolic compounds in apple peel (Tsao et al 2003;Raudone et al 2017), contributing to its strong bioactivities such antihypertensive, antioxidant, antiinflammatory activities (Balasuriya and Rupasinghe 2012;Denis et al 2013). Quercetin-3-O-glycosides-, phloridzin-, cyanidin-3-O-galactoside-, epicatechin-and chlorogenic acid-rich fractions from apple peel contributed significantly to inhibit oxidation of fish oil (Sekhon-loodu et al 2013); while, individual phenolic from apple peel inhibited myofibrillar protein carbonylation induced by free radicals (Utrera and Estévez 2013).…”

Determination of phytochemical composition and antioxidant capacity of 22 old apple cultivars grown in Poland

“…Because of the great health benefits of apples, their chemical composition and activity have been analyzed in recent years [7]. Apples are recognized as an excellent source of carbohydrates, vitamins, minerals, dietary fiber, pectin and different classes of phenolics [8][9][10][11]. A number of factors can influence the content of these compounds-agrotechnical as well as genetic [11,12].…”
