Walnut is a good source of macronutrients and micronutrients and other bioactive substances. Romania presents a long tradition being one of the leading walnut producers of EU. The aim of the study was to evaluate the mineral content and total polyphenols of the Romanian walnuts kernel originated from Banat region (western Romania). The study results show that the analyzed walnuts samples presents a high content of minerals (average value) like: potassium (404.50 mg/100 g kernels F.W.), magnesium (221.17 mg/100 g kernels F.W.), manganese (6.12 mg/100 g kernels F.W.), iron (3.67 mg/100 g kernels F.W.) and copper (2.28 mg/100 g kernels F.W.), but also high levels of total polyphenols 9.19 mg GAE/ g nuts kernel extract. Based on mineral composition and polyphenols content a database can be created for walnuts fingerprint profiles that can be used to identify the origin of undeclared walnuts cultivars.
