✔️ Material: Glass and plastic are the most common food storage materials. Glass can often be used in the oven, while plastic cannot. Plastic containers are also prone to staining when storing highly pigmented foods; glass is not.
Glass is better for the environment
When it comes to durability, longevity, and its ability to be recycled, glass is the winner!
If chemicals in plastic are a concern, we recommend choosing glass, silicone or stainless steel instead. We also recommend transferring food out of the plastic container and into a microwave- or oven-safe dish before heating.
Keep foods covered.
Store refrigerated foods in covered containers or sealed storage bags, and check leftovers daily for spoilage.
Metal containers: You will not often find metal containers meant for the fridge. You need to be mindful of what type of metal you use to store food inside the fridge. It is generally recommended to use a 100% stainless steel container to store food if using it as a fridge container.
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.
Glass is a good option for kitchen containers but it usually works out to be more expensive as compared to steel. Glass containers are also fragile and if they slip out of your hands, they could break. Steel is more durable and costs less.
When you do use plastics, look for these resin codes which are considered safer: #2 HDPE, #4 LDPE, and #5 PP. Examples of #2 HDPE (high density polyethylene) include: bottled milk, water and juice, yogurt cups, and some plastic bags.
While there is no set timeframe for replacing plastic food containers, experts say they should be tossed out when they show visible wear, chips, cracks, or signs of stains and odors. In place of plastic containers, experts recommend opting for glass or stainless steel instead.
Metal containers can react with certain foods. This can change the taste and safety of the food. Acidic foods like tomatoes and citrus fruits can cause reactions. These reactions can lead to the metal leaching into the food.
Plastic is prone to melting or discoloration whereas glass remains a durable and long-lasting solution for food storage.
Store raw food like meat, poultry, fish, sausages, bacon etc., in the bottom part of the fridge so that juices cannot drip on foods below. 2. Store ready-to-eat foods such as cooked meats, pies and dairy products such as cheese, butter, cream and yoghurt in the top part of the fridge.
Steel containers offer durability, versatility, and sustainability, making them a popular choice for many. Plastic containers are lightweight and affordable, but may not be as durable or eco-friendly. Glass containers are a stylish option that is easy to clean, but they may be heavy and fragile.
The downside to stainless steel containers is that they're not transparent, so you can't see what's inside. Another con is that unlike glass and some plastic, stainless steel containers cannot go in the microwave or oven.
The best kitchen storage containers are those that are made from stainless steel. Stainless steel is inert and thus will not react with any food material. It is also durable and long lasting.
Plastic sandwich and food storage bags are typically made from polyethylene, which is considered non-toxic.
According to National Geographic's The Green Guide, plastics #2, #4 and #5 are the safest for repeatedly storing your food. If you reuse items made from plastics #1, #3, #6 and #7 (some Tupperware products are made from #7), you run the risk of having toxic chemicals leach into the contents.
Containers made of PET plastics can release chemicals at a temperature of 25°C and at temperatures of 50°C and above, the leaching of chemicals can occur very rapidly. Food high in fat content should never be heated in plastic as the fat better absorbs chemicals.
Avoid Acidic Foods for Long Periods: Though stainless steel is resistant to corrosion, storing acidic foods (like tomatoes or citrus) for extended periods may cause minor discoloration or pitting over time.
Unlike many other items, potatoes do not actually need to be refrigerated, and, in fact, they will fare better outside the cool environment of your fridge. Storing potatoes properly will ensure you get the maximum shelf life out of the starchy, versatile vegetable.
