Zusammenfassung:Postharvest conservation of fresh fruits and vegetables is a constant challenge in the food industry. Biodegradable coatings represent an innovative and sustainable solution to extend their shelf life. In this context, this research evaluated the influence of a coating based on oxidized banana starch (Musa paradisiaca L. group AAA, cv. Cavendish) and olive oil on the conservation of cherry tomatoes (Solanum lycopersicum cv. Cerasiforme) during their storage at ambient conditions. Coating-forming emulsions were prepared using starch (4% m v-1) with a high degree of oxidation, glycerol, Tween 80, and olive oil. The products were dip coated. The starch extraction yield was 27.26% by the wet milling method. The contents of lipids, crude fiber, proteins, carbohydrates, and ashes tended to decrease in oxidized starches with increasing reaction time, the opposite behavior for humidity (P≤0.05). Solubility and oil absorption capacity increased in oxidized starches, while water absorption and swelling power decreased (P≤0.05). The best combination for the formulation of oxidized starch coatings was 3% (m v-1) of glycerol and 0.3% (m v-1) of oil. This coating reduced weight losses and delayed the ripening process. The results suggested that the use of coatings based on oxidized banana starch and olive oil is an effective strategy for maintaining the quality and freshness of the fruits during a longer storage period. La conservación poscosecha de frutas y hortalizas frescas es un desafío constante en la industria alimentaria. Los recubrimientos biodegradables representan una solución innovadora y sostenible para prolongar su vida útil. En este contexto, esta investigación evaluó la influencia de un recubrimiento a base de almidón oxidado de plátano (Musa paradisiaca L. grupo AAA, cv. Cavendish) y aceite de oliva en la conservación de tomates cherry (Solanum lycopersicum cv. Cerasiforme) durante su almacenamiento en condiciones ambientales. Se prepararon emulsiones formadoras de recubrimiento usando almidón (4% m v-1) con alto grado de oxidación, glicerol, Tween 80 y aceite de oliva. Los productos se recubrieron mediante inmersión. El rendimiento de extracción del almidón fue de 27,26% por el método de molienda húmeda. Los contenidos de lípidos, fibra cruda, proteínas, carbohidratos y cenizas tendieron a disminuir en los almidones oxidados al aumentar el tiempo de reacción, comportamiento opuesto para la humedad (P≤0,05). La solubilidad y capacidad de absorción de ace
