dc.description.abstract | El jitomate es una hortaliza ampliamente cultivada y consumida en México y es exportada principalmente a Estados Unidos, Canadá y Japón. El jitomate es atacado por algunos microorganismos, entre ellos, el moho Botrytis cinerea causando pérdidas de hasta 30% de la cosecha. Se han buscado alternativas que disminuyan la pérdida por el moho que y conserven sus propiedades fisicoquímicas de los mismos sin hacer uso de pesticidas. El objetivo del presente estudio es proponer un tratamiento con microondas alcanzando una temperatura objetivo para la muerte del moho, sin dañar las propiedades fisicoquímicas del alimento. Se usaron lotes de 350±10g de jitomates Saladette inmaduros sumergidos en 330 g de agua, se calentaron con microondas a 206 o 502 W de potencia en el horno hasta alcanzar una temperatura interna de 48°C por 1.24 min (temperatura y tiempo de muerte de B. cinerea) y se enfriaron con agua fría a 10°C. Se dejó un lote sin tratar como testigo. Los jitomates se almacenaron a temperatura ambiente durante 13 días, analizando muestras los días 1, 5, 9 y 13. | es_MX |

dc.description.abstractEnglish | Tomato is a vegetable widely cultivated and consumed in Mexico and is exported mainly to the United States, Canada and Japan. The tomatoes are attacked by several microorganisms, among them, the mold Botrytis cinerea, which causes losses even of 30% of the total harvest. Some alternatives have been explored to reduce the loss and preserve the physicochemical properties of the tomato without making use of pesticides. The objective of this study was to propose a treatment with microwaves reaching a target temperature to kill the mold without damaging the physicochemical properties of the food. Batches of 350 ± 10g of Saladette immature tomatoes were immersed in 330 g of water. Batcheswere heated with microwaves at 206 or 502 W of power in the oven until reaching an internal temperature of 48 ° C for 1.24 min (temperature and time enough to kill B. cinerea) and cooled with water to 10 °C. An untreated batch was left as a control. Tomatoes were stored at room temperature for 13 days, analyzing samples on days 1, 5, 9 and 13. The treatment at 502 W maintained the physicochemical properties of the tomato for a longer time compared to the treatment at 206 W and the control. The, the treatment at 502 W prevents tomato deterioration caused by Botrytis cinerea for 13 days at room temperature. | en |
