You generally shouldn't put tomatoes in the fridge because cold temperatures damage their flavor-producing cells, making them taste bland, and can create a mealy, mushy texture, but you should refrigerate very ripe tomatoes to slow spoilage or cut tomatoes to keep them safe, letting them warm up before eating for better flavor. For best results, store whole, ripe tomatoes at room temperature and only refrigerate if they're about to go bad.
