原始语种摘要: Abstract(#br)Free and bound non-polar lipids, glyco- and phospholipids and carotenoids of six Polish winter wheat varieties were analysed and correlated with kernels surface and cross-sections colour measured by digital image analysis. The content of total free lipids was in the range of 1617–1877 and 920–1050 mg in 100 g of wheat grain and flour, respectively, and was dominated by non-polar lipids. Free glycolipids occurred in the amount of 57–140 mg in 100 g of grain and 43–107 mg in 100 g of flour. The content of bound lipid fraction was lower than that of free lipids: 3.0–4.5-fold in grain and 1.9–3.2-fold in flour, and was dominated by phospholipids. Higher content of lutein, in most cases, was stated in flour, which points to its higher concentration in the wheat endosperm. Grain...
