abstract:
The paper presents some selected physical and chemical properties of lupine seeds from 15 different varieties. All properties were referred to five levels of moisture content, i.e. 8, 10, 12, 14 and 16%. An attempt at a description of some measured physical properties as a function of seed moisture content was undertaken. On the basis of the results obtained, an irregular distribution of chemical compounds in the seed parts was observed. Excess amounts of proteins and fat were located in the seed-leaf, while about 90% of fiber was situated in the cover. An increased moisture content resulted in a decrease in the bulk and shaken density together with a decrease in the mean dimension of lupine seeds, 1000 seeds mass and an increased chute angle.
