Blender bottles are the less advanced versions of blenders. They are mixing cups designed with a secure, tightly sealed lid and contain a metal spiral ball inside for mixing. What are they meant for? They can be used for a variety of functions: they are great for blending cocktails, pancake mix, and you can even use them to make yourself a cold ice coffee or ice tea. One of the main functions of the blender bottle is for protein powder shakes.
Are blender bottles microwave safe? While most plastic blender bottles are made of phthalate and BPA-free materials, manufacturers highly discourage microwaving. This is because there are many other dangers associated with microwaving blender bottles apart from ingesting dangerous chemicals.
Microwaving plastic releases health hazardous chemicals into the food. However, this does not apply to all plastic materials. Manufacturers are required to tests their appliances and make sure they meet certain specifications and leaking standards. Once they go through the test and data results are produced, they are then labeled microwave-safe or not.
Can you microwave blender bottles? Blender bottle materials and how they react to heat.
There are three main parts to a blender bottle\shaker bottle; the mixing mechanism, the bottle material, and the lid. Today, we are going to focus on the bottle material and how it is affected by heat. Is it safe to put any blender bottle or shaker cup into the microwave? Let’s find out
Types of blender bottles
Plastic blender bottles
Plastic shakers are the most common type of blender bottle. However, not all plastic materials are the same. The best plastic blender bottles are made from phthalate and BPA-free materials. Plastics with these components are dangerous, they can harmful chemicals that leach into your drink, causing major health issues. When it comes to plastic food-grade appliances including blender bottles, Eastman Tritan Copolyester is proven to be one of the safest plastics. It is known for its clarity, extreme durability, and its resistance to odour.
Are plastic blender bottles microwave safe?
Most blender bottles are made of BPA plastic, which absorbs and retains the odour of food when not clean out after use. Microwaving plastic has been associated with a major health concern. This is because microwaving plastic releases chemicals known as dioxin. Dioxin is mixed into the food substance in the blender and ingesting it can cause major health issues. Dioxin has been associated with causing cancer.
However, this may not be true for all plastic blender bottles. Some plastic materials do not contain dioxin, so they will not be released when they are subjected to extreme heat in the microwave. However, this does not make plastic blender bottles microwave safe. The extreme heat from the microwave might cause your blender bottle to crack or melt depending on the material.
Glass blender bottles
Blender bottles also come in glass material. Many people like glass blender bottles because of their odor and stain resistance. Because glass breaks easily, most glass blender bottles are encased in a protective sleeve, usually made out of silicone.
Are glass blender bottles microwave safe?
The glass material used to make glass blender bottles is not heat resistant, which means glass blender bottles cannot survive the microwave. To add to that, they are made with a protective silicon sleeve that is not an ideal material for the microwave.
Metal/insulated blender bottles
Insulated blender bottles are designed to keep your drink cold, especially on hot summer days. They help preserve the freshness of the drink so you can have it later in the day if you want. The blender bottles are designed with double-wall vacuum insulated stainless steel that helps keep the contents in the bottle cold/chilled for up to a 24hrs.
Are metal blender bottles microwave safe?
Never place your blender bottle in the microwave with the metal ball inside. Metal is a good conductor of electricity. This means when you place it into the microwave, electricity will flow through it easily. If you microwave your metal blender bottle, sparks will start to fly and you will destroy your blender bottle, microwave and may even cause a major accident.
Here are things to keep in mind when placing any type of blender bottles into the microwave
When microwaving any blender bottle or shaker cup, make sure you consider the possible negative effects;
If you have a microwave-safe blender bottle that is not made from metal, make sure you take out the metal mixing ball inside before you start the process.
When microwaving your blender bottle, more likely than not the inside of the bottle will become hot. This effect raises the pressure inside the bottle. If the pressure sealing lid is on, this can be quite dangerous. Because the lid is pressure sealing, the pressure will not be released until you open the lid.
If there is a lot of pressure trapped inside, it could lead to spraying hot liquids that could burn you and cause a mess in your whole kitchen. make sure you are super careful when opening the lid of a blender bottle that has been in the microwave.
Final word
Should I place my blender bottle in a microwave? Considering the multiple negative effects of placing blender bottles in a microwave, I would say not. It would be better off to just use a different type of container to heat the liquid then pour it into your blender bottle once it has cooled down a bit if you are on the go.
FAQ
Can I mix hot and warm liquids into my blender\shaker bottles?
While you definitely can, this would be a very bad idea. Placing hot liquids into a blender bottle or shaker bottle causes pressure to build up on the inside. Once you pop open the lid, the contents will spray out of the bottle, potentially burning you and causing a mess.
Can you place blender bottles in the freezer?
Depending on the materials and temperature, some blender bottles can go into the freezer. However, there is a high chance that your blender bottle will become brittle over time and this makes it susceptible to breaking or cracking.
