Place the harvested items on a clean surface or directly into storage containers. Do not put them on the ground.Use clean water to remove dirt, and keep the water clean. Usually it is better not to remove outer leaves from fruits and vegetables before storage. Without the leaves, food can become dry.
Fruits and vegetables must be cool from field heat before they are put into storage. If they are placed in cool water, however, it can spread fungus" class="hjdict" word="fungus" target=_blank>fungus throughout the food. A better idea is to harvest foods either early or late in the day, then leave them to cool naturally.
Some fruits and vegetables must be stored at zero to four degrees Celsius. Any colder, and they might be damaged. Others need four to eight degrees. And still others must be stored above eight degrees.
Wet the fruits and vegetables so they do not become too dry. The best time to do this is before storage. Cover the items in plastic once they reach the right "critical temperature" for storage. Most fruits and vegetables need the relative humidity in storage to be kept between eighty-five and ninety-five percent. Finally, leave space between the food containers and the walls of the storage area so air can flow. Keep the space clean. And try not to open the doors too often.

慢速VOA,听写,英语,VOA ,生活,食物冷藏把收获的食物放在干净的表面或直接放到储藏容器里。不要把它们放在地面上。用洁净的水清除污垢,并保持水盘清洁。通常在储藏之前,最好不要掰掉水果和蔬菜外面的叶子。没有了叶子,食物容易变干。
在放入储藏室之前,水果和蔬菜必须先从田间温度冷却下来。但是,如果把它们放入冷水中,会使真菌在食物中传播。比较好的办法是收获食物时,选择一天中不太早也不太晚的时间。
一些水果和蔬菜必须在0-4摄氏度储藏。再冷的话,它们可能就变坏了。一些要在4-8摄氏度储藏,一些必须在8摄氏度以上储藏。
在水果和蔬菜上洒点水,它们就不会变得太干,最好是在储藏之前洒水。一旦达到合适的"临界温度"就用塑料膜把它们包起来。大部分水果和蔬菜在储藏时需要保持85%-95%的相对湿度。最后,在储藏容器和储藏室墙壁之间留有一定的距离,以便空气流通。保持储藏室的干净,不要经常开门。
