Physical properties of rice.

K. R. Bhattacharya 2011

Other claims from this paper (8)

Observation Rice physical properties differ with variety, moisture content and degree of milling.
Recommendation Surface area per unit weight or normalised grain weight best classify rice grain dimensions.
Observation Density of milled rice varieties is about 1.45 g/ml.
Observation Density of paddy varies from 1.16 to 1.24 g/ml.
Association More slender rice grain has more porosity and less bulk density.
Association Increasing moisture increases density and bulk density in paddy.
Association Rice grain coefficient of friction increases with moisture.
Mechanism Excessive grain width above 2.35 mm causes rice white belly.
