    Evaluación del efecto antifúngico del microencapsulado de aceite esencial extraído de Schinnus molle sobre hongos fitopatógenos de interés agrícola
    (Universidad Técnica de Ambato. Facultad de Ciencia e Ingeniería en Alimentos y Biotecnología. Carrera de Biotecnología, 2024-02) Montachana Ibarvo, Josafat Alexander; López Hernández, Orestes Darío
    The molle is a tree of Andean origin that throughout history has been used for medicinal, culinary, textile purposes, among others, also demonstrating strong biological activity in the agricultural area for the control of pests in insects, bacteria, and fungi since it has antimicrobial properties. This is why its essential oil may be important for the development of a fungicide of biological and plant origin, which serves to control several agricultural diseases caused by phytopathogenic fungi. In the present research project, the essential oil of molle was extracted by the steam drag method, obtaining a yield of 2.8 percent, in addition to the conservation of the essential oil, the microencapsulation method by spray drying was used using of a mixture of polymers with maltodextrin and gum arabic as microencapsulating agents, in which the microencapsulation performance was qualitatively verified by means of Fourier transform spectroscopy (FTIR). Finally, with the Kirby Bauer method, it was verified in vitro that with a concentration of 100 milligrams per milliliters of microencapsulated molle essential oil there is sensitivity to Botrytis cinerea, Cladosporium spp and Fusarium spp.
