Variability of Phytonutrient Content of Potato in Relation to Growing Location and Cooking Method

摘要: Potato has a defined complement of metabolites that contribute to the human diet. Among these are carotenoids and anthocyanins. Carotenoids found in all potatoes flesh. White-fleshed varieties have 50 100 μg per g fresh weight (FW), while moderately yellow-fleshed will generally possess from 350 FW. The more intensely genotypes, which may look orange, at higher extremes levels above 1,000 highest level published is 2,600 FW diploid germplasm derived South American Papa Amarilla cultivars. predominantly lutein, xanthophyll also retina, must be obtained genotypes with extremely high total zeaxanthin, an isomer present retina.
