ca rotenoids,
whereas stir-frying and deep-frying significantly
decreased total carotenoids and (all-E)-forms of carotenoids. In
contrast, compared with commercial sterilizations, boiling caused
higher losses of carotenoids (Provesi, Dias, & Amante, 2011).
Keeping in mind the important health benefits of carotenoids,
their molecular fragility and large per capita potato consumption,
the aim of this study was (1) to investigate the fate of carotenoids
in coloured potato tubers during various conventional cooking
methods; (2) establish the carotenoid profile for each cultivar
and (3) compare the conventional yellow cultivars with the
anthocyanin-rich ones.
