Structural and functional properties of pectin

The true density of the pectin powder was determined by a gas pycnometer (Accupyc II 1340; Micromeritics, Norcross, GA, USA). A 10 ml measuring cylinder was used to measure the bulk density. The weight (W) and volume (V) of the powder were taken inside the measuring cylinder, and the bulk density of the powder was determined by the formula (2).

Bulk density (hardened)

This test method allows to evaluate the value of bulk density of hardened and dried mortar. This value is obtained as the ratio between the mass of sample after drying in oven and the volume that it occupies when it is immersed in saturation conditions. The test is performed on three prismatic samples of dimensions 40mmx40mmx160mm.
