Abstract

With the aim of exploring the nutritional characteristics of lupin seed, a first screening on three sweet cultivars, of Lupinus luteus Dukat, Mister and Taper cultivated in Poland and in Italy was performed. Protein content, oil content, fatty acid composition and nutritional indices were largely affected by the growing environmental conditions. Protein content was remarkable higher in seeds coming from Poland (37.9 – 41.9 g•kg-1) than those from Italy (32.2 – 36.2 g•kg-1); on the contrary oil quantity was higher in seeds coming from Italy (51.4 – 59.2 g•kg-1) than those from Poland (43.9 – 48.3 g•kg-1). The three varieties showed significant higher values of UFA/SFA and PUFA/SFA ratios and significant better values of Atherogenic Index (AI) and Thrombogenic Index (TI) when cultivated in Italy and, among these, Taper emerged for the highest UFS/SFA (5.62) and PUFA/SFA (3.99) ratios and for the best AI (0.06) and TI (0.09). This study indicates a strong effect of the growing conditions on nutritional traits: Continental environment seems more suited for high protein seed production, while Mediterranean environment for high oil and quality indices of fatty acid production, suggesting a diversification of the levels of inclusion of lupin, in ruminant and non ruminant feed formulation.
