    Fat and Fatty Acid Composition of Hazelnut Kernels in Vacuum Packages During Storage
    (Instituto de la Grasa, 2005) Koyuncu, M.A.; Islam, A.; Küçük, M.
    The fat contents and fatty acid compositions of three hazelnut cultivars; Tombul, Palaz and Kalinkara were investigated during storage at 21°C with 60-65% relative humidity. The total fat contents of kernels in vacuum packages increased significantly with storage time. It is believed that the absolute value of fat content does not increase but that the kernel water content and total weight decrease. The palmitic and oleic acid contents of stored hazelnuts increased, while linoleic acid content decreased. No significant differences were found for stearic and linolenic acids during storage.

    Investigation on Nut Development in Hazelnuts and Determination of Nut Characteristics and Variation Within Cultivars in Some Hazelnut Cultivars
    (International Society for Horticultural Science, 1997) Bostan, S.Z.; Islam, A.; Şen, S.M.
    This research was carried out onTombul, Kalmkara and Sivri hazelnut cultivars grown in Ordu and this study was consisted of 2 chapter. First chapter, nut length and width development of these cultivars were investigated in a hazelnut plantation involving these varieties. In the result, the width development was determined as 1, 921 cm, 1, 760 cm and 1, 621 cm, respectively; the length development was determined as 1, 930 cm, 1, 949 cm and 1, 835 cm respectively. Between plants and weeks were determined significant differences. In the second chapter, nuts were picked from average 35 hazelnut plantations in center and village. In these cultivars, nut weight, shell thickness, kernel weight and kernel ratio were determined as 1.552-2.662 g, 0.71-1.0 mm, 0.972-1.410 g, 50.51-65.06 %; 1.750-3.174 g, 0.66-1.09 mm, 0.184-1.709 g, 46 51-60.74 % and 1.669-2.605 g, 0.65-1.04 mm, 0.851-1.400 g, 48.53-56.34 %, respectively. In addition, coefficients of variation for nut weight, kernel weight and kernel ratio in cultivars were 10.05, 8.10, 5.73 %; 13.52, 14.17, 5.50 % and 10.24, 10.11, 3.86 %, respectively.
