Bioactive compounds, processing quality and yield of colored flesh potato clones

Compostos bioativos, qualidade industrial e rendimento de clones de batata de polpa colorida

Authorship SCIMAGO INSTITUTIONS RANKINGS

ABSTRACT

Colored flesh potatoes contain high concentrations of phytochemicals, such as phenolic acids, anthocyanins and carotenoids, which have therapeutic effects and promoters of human health. The objective of the study was to evaluate the concentration of bioactive compounds and industrial quality and yield traits of potato tubers. Four experiments were carried out in Pelotas-RS. In 2012 and 2013, tuber yield traits were evaluated and in 2014 and 2015, the bioactive compounds (phenolic compounds, anthocyanins and carotenoids), antioxidant activity and industrial quality traits [glucose content, dry matter (%) and frying color] were assessed. Clones C2715-01-09, C2721-22-09 and C2743-01-09, having fully pigmented purple flesh presented high concentrations of bioactive compounds and high antioxidant capacity and reasonable processing quality traits and yield potential. Clone C2743-09-09 with white flesh interspersed with purple was the most productive and had good processing attributes, but showed lower levels of bioactive compounds and moderate antioxidant activity when compared to completely purple clones.
