Comments P.80 left column top paragraph:"Few values for the density of granular wheat starch appear in the literature. Most determinations have been made by liquid pycnometric methods on air-equilibrated starch of 10 to 15% moisture content, giving values around 1.5 g/cm^3 [primary sources 1, 2]. The air-comparison pycnometer has given similar results [primary source 2]. Hess made extensive use of the differing densities of wheat starch and protein and for this purpose determined the density of starch by liquid pycnometry in Palatinol. He obtained values around 1.50 g/cm^3 and noted that small granules are denser than large ones [refs 3 – 5]."
