The residual fat content and protein content of the defatted powder were reported previously as 1.01% (w/w) and 6.13% (w/w), respectively.
This protein content is equivalent to a 100% yield of protein. The effect of the hexane extraction step on the functionality of the proteins was not determined. However, it is well known that the methods used to extract the proteins from the powder will also affect the functionality, so the additional effect of hexane extraction is likely to be negligible.
