Abstract
Objective: To evaluate the effects of laser radiation on peanut seeds as a pretreatment on the resveratrol content and fatty acid profile in the harvested seeds.
Design/methodology/approach: The experiment was established under field conditions located in the municipality of Nicolás Bravo, Chiapa de Corzo, Chiapas. The seeds were irradiated with a red laser with a wavelength of 636 nm and an intensity of 120 mW. The exposure time of the seeds to the laser was 15 min and non-irradiated seeds were used as a control.
Results: Laser radiation on seeds increased the resveratrol content in the harvested peanut seeds compared to control seeds, and changes were also observed in some fatty acids in peanut oil such as butyric acid, stearic acid and cis 11,14,17 eicosatrienoic acid. Findings/conclusions: laser irradiation applied to seeds is a low-cost biotechnological alternative that allows generating positive changes in the quality of grains from seeds harvested under field conditions.
