Abstract:【Objective】The objective of this study is to evaluate the nut traits of the dominant varieties cultivating in north Anhui Province and analyse the suitability of the varieties for processing. 【Methods】 Twenty-two varieties of Ping’ou hybrid hazelnuts were introduced to north Anhui province since 2011 among which, 9 varieties were selected as advanced varieties based on their adaptation and yielding ability. In this study, the economic nut traits, the nutritional composition, mineral elements, composition and physicochemical properties of fatty acid of hazelnut kernels were studied. According to the analyzation and evaluation of Ping’ou hybrid hazelnuts from different processing and utilization perspectives, such as baking, kernel, oil and fresh-eating, the objective of this study is to show the performance of Ping’ou hybrid hazelnuts in north Anhui province, and provide a scientific basis for the selection and popularization of Ping’ou hybrid hazelnuts. 【Results】 The results showed that, the distribution range of nut mass, nut size, nut shape index, kernel mass, shell thickness and kernel mass percentage of 9 advanced varieties were 2.54-4.40 g, 18.99-21.49 mm, 1.04-1.31, 1.00-1.66 g, 1.53-2.41 mm and 34.36%-47.01%, respectively. The distribution range of fat, protein and soluble sugar content were 50.50-58.00 g/（100 g）, 21.10-25.10 g/（100 g） and 4.08%-4.94%, respectively. There were 8 fatty acids were detected from the hazelnut kernels, including palmitic acid, palmitoleic acid, stearic acid, oleic acid, linoleic acid, arachidic acid and cis-11-eicosenoic acid, among which, the content of oleic acid was the highest one with the distribution range of 81.21%-88.53%. The content of unsaturated fatty acid was 92.19%-94.61% among the total content of fat in hazelnut kernels. In terms of mineral nutrition, the content of potassium, phosphorus, calcium and magnesium in hazelnut kernels were relatively rich. As for the processing capacity, the distribution range of single plant yield, fat production and protein production of 9 advanced varieties were1.52-2.20 kg, 330.50-503.47 g and 141.68-224.40 g, respectively. 【Conclusion】 According to different consumption patterns, the result showed that among the 9 advanced varieties of Ping’ou hybrid hazelnuts, Liaozhen 3 was the best one for base market, Liaozhen 3, Dawei and Liaozhen 4 were the best ones for kernel market, Dawei, Liaozhen 3 and Ping’ou 545 were the best ones for the fresh-eating market. Liaozhen 4 could be used as oil processing varieties, Liaozhen 1 could be used as functional protein beverage processing varieties, Dawei and Liaozhen 9 could be used as high calcium processing varieties.
