Bulk density (Akpapunum and Markakis, 1981). The loose bulk density of
product was determined by transferring 50 g product into a 250 ml graduated glass cylinder and
measuring the volume of the products off the scale. The packed bulk density was determined in
a similar way, but the volume was measured after tapping the cylinder until the products settled
(about 2 min). Both of the loose and packed bulk density were calculated as:
