Abstract
El fruto de Vaccinium corymbosum “arándano” es uno de los principales productos de agroexportación de la región la Libertad. Dentro de los desafíos más importantes de las empresas agroindustriales es el de incrementar los metabolitos del fruto de Vaccinium corymbosum “arándano” manteniendo sin alterarse las características morfométricas del fruto. Considerando que la luz LED y temperatura influyen en el aumento de grados brix y conservación de los frutos respectivamente. El objetivo del proyecto fue determinar el efecto de la luz LED y temperatura en los metabolitos y morfometría de Vaccinium corymbosum “arándano” en condiciones de postcosecha. Se adquirió frutos de Vaccinium corymbosum “arándano” de la empresa “Hortifrut”, se instaló tratamientos de luz ambiente más temperatura ambiente (25.4°C) (Tratamiento control), luz LED más temperatura ambiente (25.4°C) (Tratamiento 1), oscuridad más temperatura ambiente (25.4°C) (Tratamiento 2) y luz LED más temperatura 2° C (Tratamiento 3). Se determinó su morfometría, grados brix, pH, cuantitativamente fenoles, flavonoides, clorofila a y b de los frutos de Vaccinium corymbosum “arándano” en condiciones de postcosecha. Los resultados demostraron que la luz LED y temperatura en los metabolitos y morfometría de Vaccinium corymbosum “arándano” en condiciones de postcosecha influye de manera significativa según los tratamientos. Siendo el mejor tratamiento el de LED más temperatura de 2°C (Tratamiento 3), teniendo menor pérdida de peso, longitud polar, diámetro, menor aumento de grados brix, pH, menor perdida de clorofila a, clorofila b, clorofila a y b, fenoles, flavonoides, y un pequeño aumento en carotenos.
The fruit of Vaccinium corymbosum “blueberry” is one of the main agricultural export products of the La Libertad region. One of the most important challenges for agroindustrial companies is to increase the metabolites of the fruit of Vaccinium corymbosum “blueberry” while maintaining the morphometric characteristics of the fruit without altering. Considering that LED light and temperature influence the increase in brix degrees and conservation of the fruits respectively. The objective of the project was to determine the effect of LED light and temperature on the metabolites and morphometry of Vaccinium corymbosum “blueberry” under postharvest conditions. Fruits of Vaccinium corymbosum “blueberry” were purchased from the company “Hortifrut”, treatments of ambient light plus ambient temperature (25.4°C) (Control treatment), LED light plus ambient temperature (25.4°C) (Treatment 1) were installed. darkness plus room temperature (25.4°C) (Treatment 2) and LED light plus temperature 2° C (Treatment 3). Their morphometry, brix degrees, pH, quantitatively phenols, flavonoids, chlorophyll a and b of the fruits of Vaccinium corymbosum “blueberry” were determined under postharvest conditions. The results demonstrated that LED light and temperature have a significant influence on the metabolites and morphometry of Vaccinium corymbosum “blueberry” under postharvest conditions depending on the treatments. The best treatment being LED plus a temperature of 2°C, having less weight loss, polar length, diameter, less increase in brix degrees, pH, less loss of chlorophyll a, chlorophyll b, chlorophyll a and b, phenols, flavonoids, and a small increase in carotenes.
