When it comes to storing canned fruits and veggies, jarred sauces and other foods, it’s imperative to store them in the right place at the right temperature. All canned and jarred food should be stored in a cool, dark place. When temperatures exceed 100 degrees, it increases the risk of food spoilage in the can or jar, so when grocery shopping during the summer months, do it as one of your last errands to avoid leaving them in a hot car. At home, prolonged storage when temps are just above 75 degrees can lead to nutrient loss in the foods. And ultraviolet light can also quickly deteriorate nutrients of foods in glass jars.
