Analysis of Oil Composition in Four Varieties of Flat European Hazelnut Grown in Weibei Dry Plateau
To analyze and compare the water content,oil content and oil composition in four varieties of ma-ture flat European Hazelnut nuts grown in the Weibei Dry Plateau,and evaluate their nutritional quality,the goal is to provide a reference for their processing and preservation of these hazelnuts.The moisture content of hazelnut kernel of flat European Hazelnut was determined using baking method,while the oil content was determined by Soxhlet extraction method.Gas chromatography was used for the analysis of fatty acid composition of the oil.Data processing was conducted using Excel 2019,and SPSS 20 software was used for comparative analysis of difference.The results showd that there were significant differences in the water content of the four varieties of flat European Hazelnut,reaching a peaking of 33.81％,a minimum content of21.48％;The differences in oil content were also significant,with the highest at 61.50％,the lowest at 60.43％;There were significant differences in fatty acid composition of oil.In conclusion,the oil content in the nuts of four varieties of flat European Hazelnut grown in the Weibei Dryland exceeds 60％;The relative content of unsaturated fatty acids in the oil is higher,and the relative content of"Oleic acid+linoleic acid""is higher than 92.73％;This indicates that hazelnut oils from these four varieties can be used as high-quality and healthful edible oil.
