Antioxidant profile, antioxidant activity, and physicochemical characteristics of strawberries from different cultivars and harvest locations

Abstract

Three major cultivars of strawberries ('Yukbo,' 'Seolhyang,' and 'Janghee') harvested from three different locations (Gyeongsan, Nonsan, and Daegu) in Korea were used for this study. The soluble solid content of 'Yukbo' harvested from Nonsan was the highest among the samples. The ranges of titratable acidity and pH from the samples were 0.48-0.65 and 3.70-4.01 %, respectively. Fructose, glucose, and citric acid contents of 'Janghee' harvested from Daegu were significantly higher than other strawberries (p \ 0.05). The ascorbic acid contents of 'Seolhyang' and 'Janghee' grown in Nonsan were significantly higher than in other strawberries (p \ 0.05). Total flavonoid and phenolic concentrations, and total antioxidant activities of 'Janghee' harvested from Daegu were significantly higher than other samples (p \ 0.05). Total flavonoids and total phenolics were highly correlated with the antioxidant activities, and the relationships between total flavonoids and total phenolics were also strong. Cultivars and harvest locations may affect to the physicochemical quality and antioxidant activity of the fruit.

Bioactive Compounds and Antioxidant Activity in Different Types of Berries

“…The variability and an exact content of particular phenolic compounds of strawberries depend on many factors, such as genetic qualities, cultivation conditions, ripeness stage, storage time and conditions [ 65 , 66 , 67 , 68 , 69 , 70 , 71 , 72 , 73 , 74 , 75 , 76 , 77 , 78 , 79 ]. The content of the polyphenols such as cyanidin, pelargonidin, and quercetin glycosides displays are much more tightly regulated, supposing a consequent genetic control [ 90 ].…”

Influence of Ripening Stage and Cultivar on Physicochemical Properties and Antioxidant Compositions of Aronia Grown in South Korea

“…Organic acid composition profiling was performed as described by Kim and Shin [7], with some modifications. An Agilent 1100 series (Agilent Technologies, Wilmington, DE, USA) with a diode array detector (DAD) was used for the individual organic acid analysis.…”

“…The sugar composition profiling was performed as described by Kim and Shin [7]. Aronia sample extracts were diluted ten-fold in distilled water and then the samples were filtered through a 0.45 µm syringe filter.…”

Chemical composition and antioxidant capacity in strawberry cultivars (FragariaxananassaDuch.) by FT-MIR spectroscopy and chemometrics

“…Strawberry fruits contain important amounts of phenolic compounds with beneficial health effects, such as antioxidant, antimutagenic, and anti-inflammatory, among others (Aaby, Mazur, Nes, & Skrede, 2012;Pineli et al, 2011). Recently, it has been considered necessary to quantify the main attributes involved in the sensory quality of strawberry fruits (such as total soluble solids, total acidity, reducing sugars, pH), as well as the main bioactive compounds involved in the antioxidant capacity (ascorbic acid, phenolics, flavonoids, anthocyanins), because it is a fruit rich in antioxidants and its commercial and economic relevance requires higher quality standards (Aaby et al, 2012;Buendía et al, 2010;Pineli et al, 2011;Ríos de Souza et al, 2014;Young-Jun & Youngjae, 2015).…”
