Hello! I’m Paul, the Senior Sales of Canzo Glassware. With 18 years of experience in the glassware industry, I’m excited to share some insights from our perspective as a China glassware manufacturer. Today, we’re diving into a common question: Can you freeze food in glass containers?
Switching to glass containers in the kitchen is an excellent choice for both the pantry and freezer. Glass is made from abundant natural resources like sand and glass waste, making it an eco-friendly option. Unlike plastics, glass is free from harmful chemicals like BPA, which can be found in some plastic products. Glass containers are non-porous, so they don’t stain or absorb odors like plastic does, and they retain their sleek appearance for years. Plus, they’re easy to clean and dishwasher safe. Since glass is transparent, we can easily see what’s stored inside without having to open the container. Glass containers come in various shapes and sizes and are relatively inexpensive, but we can also be savvy by reusing jars from store-bought items like pasta sauce and pickles to build our collection.
Benefits of Freezing Food in Glass Containers
Glass offers several advantages over plastic when it comes to freezing food. One of the main benefits is durability; glass doesn’t degrade or warp over time, so it maintains its shape and structure even after repeated use. It’s also much healthier, as glass doesn’t leach chemicals into our food like some plastics might. Moreover, glass containers keep odors from lingering, so the frozen food tastes fresh even after being stored for long periods.
Another significant advantage is that glass is environmentally friendly. Since it’s made from natural resources and is highly recyclable, we’re making a sustainable choice by opting for glass containers. Reusing glass jars also reduces the need for single-use plastic bags or containers, making our kitchen more eco-friendly.
Best Foods to Freeze in Glass Containers
We can freeze almost anything in glass containers. Common foods that freeze well include fruits, vegetables, soups, sauces, and even baked goods like cookies or biscuits. Leftovers can also be stored in glass for later use. If we’re into meal prep, freezing portions of homemade baby food or vegetable scraps for stock is a great way to make use of these containers.
When freezing liquids, though, we need to be mindful that they expand when frozen. To avoid cracks or spills, it’s essential to leave some room at the top of the jar — at least 3 centimeters is recommended.
How to Freeze Food Safely in Glass
Freezing food in glass is relatively simple, but there are a few things to keep in mind to prevent breakage. First, it’s essential to use tempered glass or jars specifically designed for freezing. These containers are built to withstand extreme temperature changes. If we’re reusing glass jars from store-bought products, it’s best to choose thick, sturdy jars.
Second, always let the food cool before placing it in the freezer. If we put hot food directly into the freezer in a glass jar, the rapid temperature change can cause the glass to crack. If we’re freezing liquids, leaving space for the liquid to expand is crucial.
Cost-Effective Tips for Using Glass Containers
Although buying a set of glass food storage containers is relatively inexpensive, there are ways to be even more cost-effective. One tip is to start collecting glass jars from everyday products like sauces, jams, and pickles. These jars can be easily cleaned and repurposed for freezing food. We can also shop second-hand or visit thrift stores, where we might find high-quality glass containers for a fraction of the cost.
Repurposing glass jars also gives our freezer a uniform, organized look. The jars stack neatly, and since they’re see-through, we can quickly identify what’s inside.
Long-Term Storage and Glass Maintenance
Glass containers are built to last, but maintaining them properly ensures that they stay in top condition for years. Regularly cleaning them after each use and storing them in a safe place will prevent scratches or chips. Most glass containers are dishwasher safe, making maintenance even easier. As long as we handle them with care, glass containers will keep our food safe and fresh over the long term.
Conclusion
Freezing food in glass containers is an eco-friendly, durable, and practical option for any kitchen. With a wide range of benefits including better preservation of food, no absorption of odors, and the added bonus of being recyclable, glass is a smart choice. By following simple guidelines like leaving space for liquids to expand and using tempered glass, we can enjoy the convenience of freezing food without the risks associated with plastic. Plus, by repurposing glass jars we already have, we save money while contributing to a more sustainable lifestyle.
