Çakıldak fındık çeşidinde iç meyve iriliğine bağlı olarak biyokimyasal özelliklerin değişimi

Abstract

The study was conducted to determine reletaion in the among biochemical properties with kernel size in Çakıldak cultivar. For this purpose, kernels were divided into three groups as small (9.0-11.0), medium (11.01-13.0) and large (13.01-15.0) according to kernel size. In kernels classified according to kernel size were detected oil ratio, protein ratio, total phenolics content, total flavonoids content and antioxidant capacity (according to FRAP and DPPH assays). While the effect of kernel size on protein ratio was insignificant (p> 0.05), it was determined to have a significant effect on oil ratio, total phenolics content, total flavonoids content and antioxidant capacity (p<0.05). According to kernel size, was determined from 56.74% (small) to 58.02% (medium) for oil ratio, 16.24% (small) to 17.85% (büyük) for protein ratio, 662.3 (medium) to 763.5 (small) mg 100 g -1 for total phenolics content, 5.42 (large) to 11.56 (small) mg 100 g -1 for total flavonoids content, 3348.0 (medium) to 5883.3 (small) µmol 100 g -1 for antioxidant capacity according to FRAP assay and

Bioactive Compounds and Fatty Acid Composition of New Turkish Hazelnut Cultivars

“…Unsaturated fatty acids of hazelnuts constitute a valuable source of oil for human nutrition (Garcia et al, 1994). Such differences in protein and oil ratios of hazelnut cultivars were mainly attributed to differences in genetics and ecological conditions (Balık and Beyhan, 2019b;Beyhan et al, 2007), cultural and technical practices (Yılmaz et al, 2019), and harvest times (Farinelli et al, 2001;Seyhan et al, 2007). Pollinator cultivars were also reported to have significant effects on protein ratios of walnuts (Golzari et al, 2016) and chestnuts (Xuhui et al, 2016).…”

The Effect of Kernel Size on Bioactive Compounds in Kalınkara Hazelnut Cultivar

“…In this study, kernel size was effective in antioxidant activity. Similarly, Yilmaz et al (2019) also reported that the kernel size had an effect on the antioxidant activity. In addition, as observed in the study results, the results differed according to the different antioxidant assays applied in other studies.…”

Mincane Fındık Çeşidinde Klon Seleksiyonu: Fiziksel Özellikler

“…Its antioxidants have anticancer and antiatherosclerotic properties, and phytochemicals and phenolic compounds protect against the harmful effects of cancer and oxidative stress (Yılmaz et al, 2019). The nutritional value of hazelnut varies based on cultivar, harvest season, drying method, clonal differences, nutrition, altitude, and habitat (Turan, 2018).…”
