Portuguese. The lupine has great potential for human nutritional supplementation, in addition to having lower concentrations of alkaloids than soybeans. It is easy to grow, low-cost and is being studied as a way to improve the nutritional value of some food products. To carry out all analyzes were used seeds of Lupinus angustifolius and Lupinus albus, provided by the Agronomic Institute of Paraná - IAPAR. It was determined, as of the lupine seed flour: the composition, solubility, emulsifying capacity, foaming capacity and foam stability. The white lupine had significantly higher percentage of lipids (10.57%) compared to the values of blue (4.20%). Still, the white lupine had a higher percentage of protein (35.45%), although its value is very close to that found in blue (32.48%). Was observed a value of 48.85% carbohydrates for white lupine and 58.90% for blue. As the ash, there was a similar value in both strains (3.9% for white lupine and 3.96% for blue). For moisture, had up 2.81% for white lupine and 1.27% for blue. Emulsifying capacity was higher in blue lupine (4.00 mL / g) than in white lupine (2.27 mL / g). As for the foaming capacity, there was greater capacity for blue lupine (5.54% growth, against 1.47% of white lupine). Finally, was observed higher foam stability in the white lupine. It is concluded that the lupine presents technological properties and chemical composition that makes it useful and their use justified by the food industry.
