During processing, as well as pigment losses, many other
changes can occur in terms of the appearance, colour, texture,
and sensory properties. We thus studied a purple durum wheat
(PDW) genotype during milling and processing, as semiwholemeal
vs. semolina, and as fresh pasta vs. dried pasta. The
aim was to investigate: (1) the effects of two milling systems on
the anthocyanin and carotenoid levels and the antioxidant capacity
of PDW, as compared to a yellow durum wheat (YDW) variety; (2)
the effects of the pasta-making and cooking on the antioxidant
components; (3) the in vitro estimated glycemic impact; and (4)
the sensorial and textural properties of the different PDW pasta,
as compared to YDW and commercial durum wheat pasta.
