Abstract: Pre-harvest sprouting is a frequent problem for wheat culture that can be simulated by
laboratory-based germination. Despite reducing baking properties, wheat sprouting has been shown
to increase the bioavailability of some nutrients. It was investigated whether wheat cultivars bearing
distinct grain texture characteristics (BRS Guaraim, soft vs. BRS Marcante, hard texture) would have
different behavior in terms of the changes in phytochemical compounds during germination. Using
LC-Q-TOF-MS, higher contents of benzoxazinoids and flavonoids were found in the hard cultivar
than in the soft one. Free phytochemicals, mainly benzoxazinoids, increased during germination
in both cultivars. Before germination, soft and hard cultivars had a similar profile of matrix-bound
phytochemicals, but during germination, these compounds have been shown to decrease only in the
hard-texture cultivar, due to decreased levels of phenolic acids (trans-ferulic acid) and flavonoids
(apigenin) that were bound to the cell wall through ester-type bonds. These findings confirm the
hypothesis that hard and soft wheat cultivars have distinct behavior during germination concerning
the changes in phytochemical compounds, namely the matrix-bound compounds. In addition,
germination has been shown to remarkably increase the content of benzoxazinoids and the antioxidant
capacity, which could bring a health-beneficial appeal for pre-harvested sprouted grains. |
