Tips To Follow When microwaving Ziploc Containers
The manufacturer provides clear and concise instructions that should be keenly followed when microwaving Ziploc containers;
- The instructions provided clearly state that you should only reheat or defrost food. Cooking is not advisable as plastic containers are not capable of withstanding high cooking temperatures.
- To avoid overheating the interior part of the Ziploc container, you should carefully microwave any food that contains fats and sugars. This is because they heat up to high temperatures, so chances of the plastic container overheating and melting are usually high.
- The Ziploc container should be open to prevent any steam from building up inside. Keep on checking the container after a 1-minute interval to ensure it doesn’t overheat.
- You should put the Ziploc container together with its content in a microwave-safe container then microwave it at medium to low heat using 1-minute intervals. This helps prevent the bottom surface of the microwave from getting damaged.
- For great results, you can chop the food into tiny bits before reheating. The small bits heat up uniformly and also take a shorter time to reheat.
- If you want to add any sauces and spices to your food, you should do so at the very last seconds. If you add them from the beginning, temperatures within the container increase which can lead to overheating.
- Shorter reheating periods minimize the risk of overheating the container and warping.
- Liquids heat up quickly in comparison to foods like meat and veggies.
