A research on milling fractions of biofortified and nonbiofortified hull-less oats in terms of minerals, arabinoxylans, and other chemical properties
CEREAL CHEMISTRY(2023)
摘要
BackgroundThe aim of the study was to investigate the arabinoxylan (AX) content, yield, recovery, and enrichment factors of milling fractions obtained from short- and long-flow milling from biofortified (+) and nonbiofortified (-) oats cv. Haskara by determining the monosaccharide components besides dietary fiber and mineral contents. FindingsCoarse brans (CB) obtained by short-flow milling from Haskara (+) and (-) samples had around 3.3% AX contents and 1.5 enrichment factor while fine brans (FB) obtained by long-flow milling had around 3.8% AX contents and enrichment factors higher than CB. The differences between bran samples of Haskara (+) and Haskara (-) were significant (p < .05) in terms of insoluble dietary fiber. CB of Haskara (+) had 1.5, 2.9, and 3.8 times higher Zn, I, and Se contents than those of whole grain Haskara (-) while FB of Haskara (+) had 1.7, 4.7, and 3.7 times higher Zn, I, and Se contents than those of whole grain Haskara (-), respectively. ConclusionsMineral/fiber-rich fractions obtained by biofortification and milling applications can be used against mineral deficiency. Significance and NoveltyThis is a pioneering study on AX and mineral contents of fractions obtained by different milling flows from biofortified hull-less oats.
