Total and individual carotenoid profiles in Solanum phureja of cultivated potatoes: I. Concentrations and relationships as determined by spectrophotometry and HPLC

Genetic analysis of yield and flesh colour in sweetpotato

“…Marketable roots were considered as roots between 100 and 1200 g and with a regular shape. The root β-carotene content (RBCC) was estimated by cutting the fresh root longitudinally, comparing the flesh colour to the colour chart used by Burgos et al (2009), and recording the corresponding β-carotene value indicated by the colour chart.…”

Nutrients, bioactive non-nutrients and anti-nutrients in potatoes

“…Burgos et al (2009b) determined the total and individual carotenoid profiles in raw tubers of a sample of 23 accessions of Solanum phureja cultivated potatoes in two papers in this issue, first by spectrophotometry and HPLC. The authors identify two accessions which contains the highest concentration of zeaxanthin (1290 mg 100 g À1 FW) reported thus far for potatoes, including genetically modified potatoes; see Fig.…”

Effect of boiling on the total phenolic, anthocyanin and carotenoid concentrations of potato tubers from selected cultivars and introgressed breeding lines from native potato species

“…The carotenoid profiles and concentrations in tubers of Solanum phureja Juz. & Bukasov have been correlated with the intensity of yellow flesh color, and zeaxanthin and antheraxanthin were found as the predominant carotenoids in deep yellow-fleshed varieties while violaxanthin, antheraxanthin, lutein and zeaxanthin constituted the main carotenoid profile of yellow potatoes, and violaxanthin, lutein and b-carotene in cream-fleshed potatoes (Burgos et al, 2009).…”
