Harvesting and Postharvest Recommendations for Tomato

The most popular type of tomato in the country is a medium-sized, globe-shaped fruit harvested at the mature green stage. This variety is typically ready for harvest 60 to 70 days after transplanting. Harvesting tomatoes should be done every 2 to 3 days, with the optimal time being early in the morning from 6:00 to 10:00 am or in the afternoon from 4:00 to 6:00 pm. Harvesting should be avoided when the fruit is wet or after rainfall, as high moisture can cause fungal or bacterial problems. Tomatoes should be cut from the plant using a knife or scissors, and harvesting should not be done when the temperature exceeds 32°C, as this can cause the fruit to ripen quickly. After harvesting, the fruit is cleaned and sorted into three groups based on color and size. Cleaning can be done manually by rubbing the fruit surface with a soft damp cloth or by washing with potable water and air-drying the fruit under a shaded area. Sodium Hypochlorite at a concentration of 150 ppm can be used as a sanitizing agent if potable water is not available. Spoiled fruit should be removed before washing to avoid contamination. Packing for transport involves using strong, well-ventilated containers such as wooden containers, durable plastic crates, or bamboo baskets. The container should have protective padding such as banana leaves to cushion the fruit and prevent scarring and abrasions. The fully loaded container should be taken to a shaded, well-ventilated temporary holding area, and overloading should be avoided to prevent damage to the fruit. Transporting tomatoes requires careful consideration to maintain their quality. Containers should be arranged on a shelf to avoid piling on top of each other, and a cloth should be used to cover the basket to protect the fruit from sunlight and dust. The vehicle used for transporting should either have refrigeration or a roof to protect the fruit from direct sunlight. Storage of tomatoes involves keeping them in a cool place under the house or in shaded, well-ventilated areas. To maintain freshness, a wet cloth should be used to cover the baskets, and the cloth should be frequently sprinkled with clean water to keep the fruit cool. For long periods of storage (up to 10 days), tomatoes should be stored at 12-16°C with a relative humidity of 90-95%. Tomatoes are a nutritious food source, rich in vitamins A and C, dietary fiber, and low in fat with no cholesterol. One medium-sized tomato represents 20-25% of the daily requirements for these vitamins, making them a heart-healthy food.
