As we rush through our busy lives, it’s easy to rely on the convenience of microwaving our morning coffee or tea. However, if you’re a Dunkin’ fan, you may have noticed a warning on their cups that reads, “Do not microwave.” But why is this warning there, and what happens if you ignore it? In this article, we’ll delve into the reasons behind this warning and explore the potential risks of microwaving Dunkin’ cups.
The Materials Used in Dunkin’ Cups
To understand why Dunkin’ cups should not be microwaved, let’s first look at the materials used to make them. Dunkin’ cups are typically made from a type of paperboard called poly-coated paperboard. This material is designed to be durable and resistant to moisture, making it ideal for hot beverages. However, it’s not suitable for microwaving.
The poly-coating on Dunkin’ cups is made from a type of plastic called polyethylene. This coating helps to prevent the paperboard from becoming soggy or weak when exposed to hot liquids. However, when heated in a microwave, the polyethylene coating can melt and release chemicals into the beverage.
The Risks of Microwaving Poly-Coated Paperboard
Microwaving poly-coated paperboard can pose several health risks. When the polyethylene coating melts, it can release chemicals such as bisphenol A (BPA) and phthalates into the beverage. These chemicals have been linked to various health problems, including cancer, reproductive issues, and neurological damage.
In addition to the health risks, microwaving poly-coated paperboard can also cause the cup to become misshapen or even catch fire. The microwave energy can cause the polyethylene coating to melt and bubble up, leading to a messy and potentially hazardous situation.
The Science Behind Microwaving
To understand why microwaving Dunkin’ cups is a bad idea, let’s take a look at the science behind microwaving. Microwaves work by using non-ionizing radiation to heat up water molecules in the food or beverage. This process is called dielectric heating.
When a microwave is used to heat up a beverage in a poly-coated paperboard cup, the microwave energy can cause the water molecules in the beverage to heat up rapidly. However, the polyethylene coating on the cup can also absorb some of this energy, causing it to melt and release chemicals into the beverage.
The Role of Moisture in Microwaving
Moisture plays a crucial role in the microwaving process. When a beverage is heated in a microwave, the water molecules absorb the microwave energy and convert it into heat. However, if the cup is not designed to withstand the microwave energy, the moisture in the beverage can cause the cup to become misshapen or even catch fire.
In the case of Dunkin’ cups, the poly-coated paperboard is not designed to withstand the microwave energy. The moisture in the beverage can cause the polyethylene coating to melt and release chemicals into the beverage, posing a health risk to the consumer.
What Happens When You Microwave a Dunkin’ Cup?
So, what happens when you microwave a Dunkin’ cup despite the warning? The consequences can be messy and potentially hazardous. Here are a few possible scenarios:
- The cup becomes misshapen: The microwave energy can cause the polyethylene coating to melt and the cup to become misshapen. This can lead to a messy situation, with hot beverage spilling everywhere.
- The cup catches fire: In extreme cases, the microwave energy can cause the polyethylene coating to ignite, leading to a fire. This is a rare but potentially hazardous scenario.
- Chemicals are released into the beverage: The microwave energy can cause the polyethylene coating to melt and release chemicals into the beverage. This can pose a health risk to the consumer, especially if the beverage is consumed hot.
A Real-Life Example
In 2018, a woman in the United States sued Dunkin’ Donuts after she claimed that microwaving one of their cups caused it to catch fire and burn her. The woman alleged that the cup was defective and that Dunkin’ Donuts had failed to warn consumers about the risks of microwaving their cups.
While this is an extreme example, it highlights the potential risks of microwaving Dunkin’ cups. It’s essential to follow the warning on the cup and avoid microwaving it to prevent any accidents or health risks.
Alternatives to Microwaving Dunkin’ Cups
