 C. maxima is more sensitive to cold than C.avellana. Their main growing area is located in the Turkish Black Sea region, where three-quarters of the world's produced commercially available "hazelnuts" are produced.  C. maxima is more sensitive to cold than C.avellana.

 Volatiles of hazelnut oil (Turkey, cold-pressed from roasted seeds) were characterized by high amounts of acetic acid (33.7%), 3-methylbutanal (19.1%), 2-methylbutanal (14.0%), and hexanal (3.3%). Compounds with known impact on roasted notes were 2-methylpyrazine (3.2%), furfural (2.3%), furfurylalcohol (0.5%), dimethylpyrazines (4.4%), γ-butyrolactone (1.1%), and benzaldehyde (0.7%). \\ Volatiles of hazelnut oil (Turkey, cold-pressed from roasted seeds) were characterized by high amounts of acetic acid (33.7%), 3-methylbutanal (19.1%), 2-methylbutanal (14.0%), and hexanal (3.3%).

 Hazelnut paste for hazelnut spread: "A set of authentic hazelnut pastes and model samples containing various hazelnut paste amounts (from 0.1% to 28%) were analysed. Due to the variability found in filbertone content, it was not possible to propose a sufficiently robust model for the hazelnut paste quantification, however, filbertone was found to be a proper marker for the quality sorting of commercial hazelnut spreads.  Available  hazelnut  spreads  from  the  market  were  analysed  and  classified  into  three  groups:  samples  with  minimal content of hazelnuts (less than 1%, the filbertone content lower than 4 μg/kg); samples with middle contents of hazelnuts (from 1% to 10%, filbertone 4-45 μg/kg); superior samples with high contents of hazelnuts (above 10%, filbertone above 45 μg/kg)." \\ Hazelnut paste for hazelnut spread: "A set of authentic hazelnut pastes and model samples containing various hazelnut paste amounts (from 0.1% to 28%) were analysed.
