Comparison of physicochemical and bioactive contents of 36 different quince cultivars and genotypes

Abstract

In this study, 36 cultivars and genotypes of quince fruits were harvested as materials from the collection garden of Yalova Atatürk Horticultural Central Research Institute. This study aims to determine the nutritional contents of quince cultivars and genotypes, including vitamin C (L-ascorbic acid mg/100 g), reducing sugar content (glucose mg/100 g), mineral substances (N, Fe, Mn, Zn, Cu, K, Ca, Mg, P; mg/100 g, Ash %), total antioxidant activity (DPPH, FRAP, ABTS, CUPRAC; µmol/100 g TE), total phenolic content (mg/100 g GAE), SSC (%), titratable total acidity (%), and pH and color values (L*, a*, b*). Based on these evaluations, quince cultivars and types with the highest nutritional content beneficial to human health were determined. This study can contribute to recommending high-nutrient cultivars and types to producers for cultivation in broder areas and promoting their widespread adoption.
