Microwave popcorn is a convenience food consisting of unpopped popcorn in an enhanced, sealed paper bag intended to be heated in a microwave oven. In addition to the dried corn the bags typically contain solidified cooking oil, one or more seasonings (often salt), and natural or artificial flavorings or both. With the many different flavors, there are many different providers.
Design
The bag is typically partially folded when it is placed in a microwave, and inflates as a result of steam pressure from the heated kernels.
The design of a microwave popcorn bag is specifically keyed to avoid popped kernel scorching, an undesirable effect that takes place when popped kernels are heated above 300 °F (149 °C).[1]
A susceptor, usually a metalized film laminated onto the paper of the bag, absorbs microwaves and concentrates heat at the film interface, thus ensuring a heat distribution focused on the hard-to-heat flavor coating so that the unpopped kernels are evenly coated prior to popping, thereby ensuring even flavor throughout the product. Additionally some popcorn is flawed and will not pop because of possible damage to the shell which allows the steam to escape. These unpopped kernels are known as "old maids" or "spinsters".[2]
An early susceptor popcorn bag design was patented by the American company General Mills in 1981 (US Patent #4,267,420).[3]
Safety issues
Care in package design is needed for food safety.[4]
Home-made alternatives
It is possible to heat popcorn in the microwave using simple paper bags,[5] or popping the popcorn in the microwave in other containers including large glass bowls with heavy, but not airtight glass lids. These homemade approaches allow greater control over flavoring and exposure to PFOA, but have a chance of leaving some corn kernels unpopped due to randomness of the microwave radiation distribution in a microwave.
