Drying is one of the most important stages in pasta production because of its influence on texture and colour. Whole grain pasta has been associated with greater cooking loss and softer texture. The objective of this research was to examine the impact of the drying profile and whole grain content on pasting and physicochemical properties of starch in macaroni and see how the qualitative properties of macaroni are affected. A flour × drying interaction was detected in pasting properties of the samples with differences observed in peak viscosity, peak time and final viscosity in whole grains following drying. Hot stage microscopy showed restricted granule swelling following treatment, reducing amylose leaching, which partly governs viscosity. DSC showed a significant increase in ALC formation upon treatment, which can also reduce leaching. While the interaction between these main effects was significant for cooking loss, firmness and adhesiveness measured instrumentally, differences between drying conditions for either textural attribute could not be detected using a trained panel.
