| Sumario: | Wheat sprouts are a source of carbohydrates, fiber, vitamins, essential nutrients
and bioactive compounds that have been linked to the prevention and treatment of
illnesses. The presence of these compounds in wheat sprouts may be increased by
means of the application of organic acids during the growth stage. The objective of this
investigation was to evaluate the effect of a sprayed application of citric acid (0, 10-2,
10-3, 10-4 and 10-5 M) on the total antioxidant capacity and total content of phenolic
compounds and flavonoids in wheat sprouts. A completely randomized design was
used, consisting of six repetitions. The results showed that phenolic compounds, flavonoids
and antioxidant capacity increased significantly with the application of a 10-2 M
foliar spray as compared to the control. As such, the spraying of low concentrations of
secondary metabolism-inducing molecules during the sprout development process is a
useful and effective method to stimulate the biosynthesis of bioactive phytochemicals
and improve the nutraceutical quality of wheat sprouts.
