Resumen

Technologies such as UV-A radiation applied to sprouted sorghum can stimulate the synthesis or release of phenolic compounds. Since the optimal conditions for stimulating the formation of these compounds in sorghum sprouts are unknown, we used the response surface methodology to identify the optimal conditions of irradiation duration and intensity to obtain the highest free phenol content and antioxidant activity in sprouted sorghum. The results showed that, compared with nonirradiated sorghum sprouts, sprouts irradiated under the optimal duration of 11.7 h and the optimal intensity of 5.4 µW/cm2 had a significantly higher phenol content (26.3%) and antioxidant activity as measured by DPPH (28.3%) and TEAC (21.1%) assays. Our findings suggest that UV-A radiation can help develop sorghum sprouts with high biological potential that can be used to produce healthy foods for human consumption.
