When freezing soup, you can use whatever container you want as long as it's safe for the freezer and you leave the headspace as noted above. You can use freezer-safe containers made of plastic or glass as well as freezer-safe bags. There are also handy silicone freezing trays available made specifically for soup.
Use any airtight, freezer-safe containers for soup. You can use plastic or glass, as long as it has a tight-fitting lid.
- Plastic: High-density polyethylene (HDPE) and polypropylene (PP) are generally safe. Avoid thin, flimsy plastics. - Silicone: Food-grade silicone is typically freezer safe. Labeling: Check for any labels or symbols indicating that the container is freezer safe. Many manufacturers will specify this on the packaging.
Only put plastics in the freezer if they have a freezer-safe label. Single use containers, such as ice cream or milk cartons, should be avoided for freezer use. According to MSU Extension, use containers in the freezer that are moisture-vapor resistant, leak proof, and easy to seal.
Go for glass or something reusable like silicone. Do you need an affordable and easy-to-store option? Plastic deli-style containers are a great choice available in a variety of sizes. Plastic, glass, and silicone are all suitable for freezing soup, though glass and silicone will likely last longer.
Room can be left in containers to account for this expansion but it is not always able to prevent damage to a container. Polypropylene and PVC are both plastics that are brittle at temperatures below freezing. Polystyrene is considered brittle at 68°F and is very brittle at temperatures below freezing.
Glass containers, in contrast, are toxin-free, easier to clean, and safe for freezing and heating. Choosing glass food storage containers helps reduce exposure to environmental toxins, which is crucial for overall health and reducing the risk of chronic illness.
Leaching is when chemicals such as BPA are transferred from the plastic to food. It is commonly transferred through changes in temperature. For example, when you microwave food, if you are using plastic, the chemicals will leach in to your food. Similarly, leaching can also occur if left in the freezer.
Rubbermaid's Brilliance containers are affordable, durable, and is approved for use in the microwave, dishwasher, and freezer. Plus, their crystal-clear design lends them a more expensive look than your typical plastic tupperware.
Those materials can split, crack and sometimes even shatter when subjected to freezing. However, freeze grade plastics are specially designed to retain some flexibility while still retaining structural rigidity in freezing environments. Freeze Grade Plastic is moisture vapor resistant and has low odor absorption.
It is safe to freeze meat or poultry directly in its original packaging, however this type of wrap is permeable to air and quality may diminish over time. For prolonged storage, overwrap these packages as you would any food for long-term storage.
Our borosilicate glass products can be put into freezer and can resist till -40°c.
Ladle soup into an airtight bag like Glad® FLEX'N SEAL™ Freezer Quart Bags, leaving an inch or so of space. Squeeze out any air before tightly sealing and laying bags flat in the deepest part of your freezer. Once the bags' contents are frozen, you can stack them on top of each other to save space.
Leaching and Food Safety
This can occur when the plastic interacts with acidic or high-temperature foods. To ensure customer safety, it's advisable to choose plastic soup containers that are specifically designed to resist leaching, reducing the risk of chemical contamination.
If you're in a rush, place the soup in its container in a warm water bath until it is fully thawed. The in-between option is to immerse the container in warm water to loosen the frozen soups from the sides.
It is safe to freeze your soup in plastic containers, so long as they're the right containers. Not all plastics are made equal. Always store food in containers that are made from safe plastics and do not contain polyvinyl chloride, polycarbonate, or polystyrene.
They're in your kids' lunchboxes, your kitchen drawers, and probably in your refrigerator. Ziploc storage bags have been a part of American culture for decades. But those toxic plastic baggies are leaching harmful chemicals into your food – and killing marine life.
Whichever chemicals they contain, plastics break down over time and can potentially release trace amounts into food. “This is more likely to happen when the plastic has been heated or when it's old and has been repeatedly used and washed,” she says.
A: No. There are a lot of plastic containers and bags specifically for use in food storage, including freezing. Meat in trays and commercial plastic wrap can be safely frozen as they are, but make sure you thaw meat at a cool temperature.
Our Ziploc® products are suitable for food contact use for microwave defrosting and reheating, room temperature, refrigeration, and freezing. Remember, it's always important to follow each product's usage instructions. Furthermore, Ziploc® brand products are made in accordance with Good Manufacturing Practices.
We know that the density of ice is less than of water. When water freezes into ice the volume of system increase ,hence it will break the glass bottle.
LDPE — Low density polyethylene plastics are listed as the number 4 on the triangle code. They are used for a wide range of items such as dry-cleaning bags, bread and frozen food bags and squeezable bottles for mustard and honey.
1. Plastic storage containers. Plastic storage containers provide an easy, fool-proof way to store meat in the freezer. Plastic containers are readily available in most supermarkets.
