Frequently Asked Questions
Is it better to freeze food in plastic or glass?
While plastic containers can release chemicals when frozen, glass containers provide a safer option for freezing food. Glass containers that are specifically designed for freezer and refrigerator use are free from releasing harsh chemicals and remain intact even when frozen. This makes glass a better choice for ensuring optimal food safety during freezing.
Why can’t you put glass in the freezer?
You should avoid putting glass in the freezer for a couple of reasons. Firstly, glass is fragile and susceptible to thermal shock. The extreme temperature difference while going from room temperature to freezing can cause the glass to shatter and create a mess inside your freezer. Secondly, when liquids freeze, they expand in volume. If you place a full glass container in the freezer, there won’t be enough room for the contents to expand, resulting in a potential explosion. To prevent this, it is best to leave some space in the container, about an inch or two below the lid, allowing the contents to expand as they freeze without risking any breakage or damage.
What is the best container to freeze food in?
When it comes to freezing food, rigid containers and flexible bags or wrapping are both safe options. However, rigid containers made of plastic or glass have an added advantage. These containers are versatile and can be used for various types of packs, but they particularly excel at storing liquids. The straight sides of rigid containers also make it incredibly convenient to remove frozen food without any hassle. So, if you’re looking for the best container to freeze your food in, one made of glass or plastic with straight sides is the way to go.
What container material should never put in the freezer?
While glass containers and cans are typically not suitable for freezing due to the risk of explosion, there is another material that should absolutely be avoided in the freezer – Styrofoam. Styrofoam is a type of expanded polystyrene foam that is commonly used for takeout containers and disposable cups. However, subjecting Styrofoam to freezing temperatures can cause it to become brittle and break apart, potentially contaminating the food stored inside. Therefore, it is wise to steer clear of putting Styrofoam containers in the freezer to ensure food safety and prevent any unwanted mess.
