How To Use Plastics Safely In Food Prep

Love them or hate them – plastics make up a big bulk of our daily lives, from the bags that our groceries come in to the containers that our takeaway lunch is packed in.

Plastics have had an unsavoury reputation in recent years, especially in food preparation and storage as they are known to melt, catch fire and “migrate” into food when used incorrectly.

Here’s a checklist by the Singapore Food Agency (SFA) on what you should not be doing with your plastic wares.

1. Microwaving plastics

Only plastic containers that are labeled microwave-safe (you can see this on the base) should be used for reheating food. Otherwise, the material isn’t heat-stable and can leach into your food.

2. Plastic cling film

Never use this in an oven or over pots and pans unless otherwise stated. Even if a brand of cling film is microwave-friendly, it should never come into direct contact with food as it can melt into your dish when hot.

3. Takeaway boxes

These are mostly made for single use and not for storing food over a long period. This means that if you are buying cooked food for the next day, always transfer it into a proper storage bowl or plate before refrigerating it.

4. Plastic food containers

These are usually reusable and are used to store cookies, dried food such as beans and condiments. However, once they are cracked or have turned “cloudy”, they should be replaced.

5. Polycarbonate baby bottles

Never put boiling water into these as hot water can cause the bottle to release chemicals into the milk. The best choice is glass bottles.
