The United States of America Boston chef laboratory researchers on the tomatoes placed on the tip of the tip of the downward placed on the comparative experiments. The results found that tomatoes placed with the tip up rotted faster. The tomatoes stored tip-down were kept at room temperature for a week and remained intact. The reason for this is that placing the tomatoes stem side down prevents air from entering the tomatoes and prevents the moisture from escaping through the stem scars.

Nutrition experts say tomatoes can also be stored in plastic bags at room temperature. The specific method is: choose the fruit body intact, five or six minutes ripe tomatoes, will be placed in a plastic grocery bag, tightly tied mouth, placed in a cool place. Open the mouth of the bag 1 time a day, ventilation for 5 minutes. If there is water inside the plastic bag, dry it with a towel or change the plastic bag, and then tighten the mouth of the bag. The tomatoes in the bag will gradually ripen and, in this case, can usually be kept for about 30 days.
