BACKGROUND: Three cultivars of Lupinus albus L. (Lutteur, Lublanca and Multitalia) were assessed for proximate composition, fatty acids, alkaloids and in vitro fermentation characteristics over three harvest years. RESULTS: The chemical composition varied greatly during the three harvest years. Crude protein content ranged from 353 to 456 g kg(-1) dry matter (DM), neutral detergent fiber content from 209 to 321 g kg(-1) DM and lignin content from 3.0 to 63.9 g kg(-1) DM. Lublanc showed the highest crude protein (417 g kg(-1) DM) and lignin (35 g kg(-1) DM) contents. High levels of lipids (89.9 g kg(-1) DM) and starch (93.3 g kg(-1) DM) were found in all samples. Alkaloid content ranged from 3.63 to 165mg per 100 g. Lutteur and Lublanc showedmore favorable n-3/n-6 polyunsaturated fatty acid ratios (from0.44 to 0.73) and lower values of the anti-quality factor ` erucic acid' (from5.8 to 20.9 g kg(-1)) thanMultitalia. Lutteur showed higher degradability (897 g kg(-1)), gas production (330 mL g(-1) organicmatter (OM)) and volatile fatty acid production (117 mmol g(-1) OM) than the other varieties. CONCLUSION: The present data suggest L. albus L. cv. Lutteur to be a promising crop as food thanks to its high nutritive traits andmost constant yield over time. (C) 2014 Society of Chemical Industry
