It was concluded that the cornelian cherry fruits harvested at MS-2 stage of maturity and preserved in MAP better maintained quality attributes throughout their shelf life. © 2018 Society of Chemical Industry.

In this study, 14 well-adapted genotypes of pistachio (Pistachio vera L.) grown in Diyarbakır (Southeastern Turkey) and 15 walnut (Juglans regia L.) genotypes grown in Erzincan (Eastern Turkey) have been studied. Pistachio genotypes contained 8.16-9.33% palmitic acid, 0.54-0.68% palmitoleic acid, 2.35-4.21% stearic acid, 67.81-76.82% oleic acid, 9.42-18:32% linoleic acid, 0.27-0.38% linolenic acid and 0.19-0.33 % arachidic acid. The range of selenium, α-tocopherol, γ-tocopherol, δ-tocopherol, α-tocotrienoid, γ-tocotrienoid and total carotenoid of these promising genotypes were found to be between 11.44 and 190.71 ng/g, 1.36 and 26.93, 36.17 and 170, 0.45 and 2.61, 0.96 and 3.76, 2.33 and 37.72 and 1.01 and 4.93 mg/kg, respectively. Linoleic acid ranging from 43.19% to 53.16% was the most abundant fatty acid in 15 pomologically selected walnut genotypes, followed by oleic and linolenic acids (31.91% and 11.46%, respectively). Their selenium contents ranged between 7.25 and 57.67 ng/g. γ-Tocopherol was the predominant tocopherol in walnut genotypes. Pistachio and walnut genotypes with higher unsaturated fatty acids, tocopherols and selenium contents may be valuable for nutritional breeding efforts.

The effects of storage temperature on weight loss, flesh firmness, color characteristics, soluble solids content (SSC), titratable acidity, vitamin C, total phenolics, total flavonoids, antioxidant activity and individual phenolic compounds of cherry laurel fruits (Prunus laurocerasus L. cv. Kiraz) during storage (at 2 6 0.5C and 90 6 5% RH) were investigated in this study. The weight losses of fruits increased with the increasing storage durations. The weight loss was 11.11% at the end of storage. While flesh firmness, titratable acidity and vitamin C decreased throughout the storage, an increase was observed in SSC values. Throughout storage period, an increase was observed in L* and hue angle and a decrease was observed in chroma values. Total phenolics, total flavonoids, individual phenolic compounds and antioxidant activity decreased throughout the storage period. Chlorogenic acid was the major phenolic acid in cherry laurel fruits. PRACTICAL APPLICATIONSCherry laurel fruit are rich in flavonoids and phenolic compounds with significant antioxidant effects. The storage temperature can provide significant contributions to market value and prevention of nutritional values of the cherry laurel fruits. This study revealed that storage temperature was effective in delaying softening of fruits and maintaining bioactive compounds of cherry laurel fruits.
