Abstract

In this study, nutrient contents for human diet and some physical properties that are important for the design of equipments for sowing, harvesting, processing, transportation, sorting, separation and packaging of lupin cv. grown in Turkey were determined. Mineral contents of lupin seeds including P, K, Ca, Mg, Na, S and B, Cu, Fe, Mn, Zn were determined 0.14%, 0.4%, 0.04%, 0.06%, 0.02%, 0.06%, 22.3 ppm, 3.6 ppm, 11.9 ppm, 533.4 ppm,15.8 ppm respectively. The physical properties were evaluated as functions of moisture content in the moisture range from 7 to 35% d.b. for the rewetted lupin seed. As a result, the average length, width, thickness, the geometric mean diameter, sphericity, unit mass and volume were 9.5, 8.4, 4.9, 6.61 mm, 73.9%, 0.27 g and 0.18 cm3, respectively. The bulk density decreased from 727.2 to 678.8 kg/m3, true density decreased from 1428.5 to 1000 kg/m3, porosity decreased from 48.8 to 32.1%, one thousand seed mass increased from 230.7 g. to 327.4 g, the sphericity of lupin seed decreased from 73.9 to 71.5% while the moisture content of lupin seed increased from 7 to 35% d.b..
