The effects of extrusion temperature and whey protein concentration on the physical properties of corn starch were studied. Correlations between the physical properties of the extrudates and internal chemical bonds in proteins were studied using Pearson's statistical method.

Ascorbyl palmitate (AP) is an amphiphilic molecule due to its structure (a hydrophobic hydrocarbon chain and a hydrophilic ascorbyl group) (Palma, Lo Nostro, Manzo, & Allemandi, 2002).
