Most of us are assured that our microwave containers are safe as it is mentioned at the back of the container and we are certain that it won’t cause any problem. However, if you think that these are the only criteria needed to stamp them with a microwave-safe guarantee, think again.
What is wrong in using microwave-safe containers?
After doing the safety test (see box below), you can assure yourself that good quality microwave containers are safe for use. However, containers with very thin plastic body are not safe at all even though they may be marked so. Many studies conducted by scientists say that these containers release BPA (Bisephnol A), which can latch on to the food when it is heated. Exposure to BPA in small doses is considered to be more harmful than larger ones and the effects are longer. BPA is considered to be inherently toxic by environmentalists, too, who have urged a ban on it.
It is better to avoid reusing containers that are used for take-aways and home delivery. According to studies, such plastic containers have a high affinity for fats and once they come in contact with food high in oil or fat-based substances, they can never be truly clean for a second use. The plastic is irrevocably altered even though it was originally marked as food grade. Also remember, that any containers, if they have been used to store non-food items like detergent or paint should never be used for storing food.
Other safe options
Heavy glass jars, which are marked food grade and used to store food can be directly used in the oven. It is also safe to re-heat food in good quality glassware. However, avoid decorative glass plates since the dyes and pigments used for the decorative colours and finish, may not be food grade. Even if there is a minute metallic trim and design on the glassware, it should be avoided. Paper towels or paper plates too are a safe bet to reheat food. If using ceramic ware, you need to check these first by heating them when they are empty.
