The present study investigates the impact of magnetic biostimulation on seeds of purple maize (Zea mays L.), variety INIA 601, cultivated in Cajamarca, Peru, with a particular focus on their physical characteristics, yield, bioactive compounds, and antioxidant activity. The results demonstrated that seeds treated with pulsed (8 mT at 30 Hz for 30 min) and static (50 mT for 30 min) magnetic fields exhibited significantly longer cobs (16.89 and 16.53 cm, respectively) compared with the untreated control (15.79 cm). Furthermore, the application of these magnetic fields resulted in enhanced antioxidant activity in the bract, although the untreated samples exhibited higher values (110.56 mu g/mL) compared with the pulsed (91.82 mu g/mL) and static (89.61 mu g/mL) treatments. The geographical origin of the samples had a significant effect on the physical development and the amount of total phenols, especially the antioxidant activity in the coronet and bract. Furthermore, a total of fourteen phenols were identified in various parts of the purple maize, with procyanidin B2 found in high concentrations in the bract and crown. Conversely, epicatechin, kaempferol, vanillin, and resveratrol were found in lower concentrations. These findings underscore the phenolic diversity of INIA 601 purple maize and its potential application in the food and pharmaceutical industries, suggesting that magnetic biostimulation could be an effective tool to improve the nutritional and antioxidant properties of crops.The APC was funded by Universidad Nacional Toribio Rodriguez de Mendoza de Amazonas, Peru, and the National Program for Scientific Research and Advanced Studies (PROCIENCIA)-CONCYTEC for financing within the framework of the call for Applied Research and Technological Development Projects 2020-02-Phase II [Contract No. 205-2020-FONDECYT].MDPI AGDepartamento de Tecnología de AlimentosInstituto Universitario de Ingeniería de Alimentos (FoodUPV)Escuela Técnica Superior de Ingeniería Agronómica y del Medio NaturalUniversidad Nacional Toribio Rodríguez de Mendoza de AmazonasFondo Nacional de Desarrollo Científico, Tecnológico y de Innovación Tecnológica, PerúRepositorio Institucional de la Universitat Politècnica de València Riunet20252025-06-10journal articlehttp://purl.org/coar/resource_type/c_6501VoRhttp://purl.org/coar/version/c_970fb48d4fbd8a85info:eu-repo/semantics/articleapplication/pdfhttps://riunet.upv.es/handle/10251/224393reponame:RiuNet.
