Abstract

A range of physical properties of seed of edible asparagus were determined as a function of moisture content. As the moisture content was increased from 8.7 to 31.2% w.b., the average length, width, thickness and the geometric mean diameter varied from 3.8 to 4.45, 3.36 to 3.93, 2.36 to 2.72 and 3.11 to 3.62 mm, respectively. In the same moisture, studies on rewetted asparagus showed that the sphericity, surface area and thousand seed mass increased from 0.807 to 0.822, 30.37 to 41.15mm2 and 21.1 to 31.24g, respectively. As the moisture content was increased from 8.7 to 31.2% d.b., the bulk density and porosity were found to decrease from 630 to 530 kgm , 1360 to 1040 kgm and 53.67 to 49.03% ,whereas the terminal velocity ,dynamic and static angle of repose were found to increase from 9.79 to 11.44 m/s , 0.41 to 0.49 and 0.29 to 0.38 ° respectively.The static coefficient of friction on rubber,aluminum,plywood,glass,iron and galvanized iron sheet also increased linearly , with increase in moisture content. The rubber and galvanized iron sheet offered the maximum and minimum friction respectively
