“…AR are commonly found in cereal grains, which so far have been their major source [ 3 ]. The highest AR contents have been reported in wheat bran, rye, and triticale, whereas maize, oats, and rice have smaller amounts [ 4 , 5 ]. ARs accumulate in the grain’s intermediate layers (hyaline layer, integument, and intermediate pericarp), and can be extracted via maceration or other emerging methodologies, such as extraction using supercritical CO 2 and methanol or ethanol as co-solvents [ 6 , 7 ].…”
