From the article: Most of us rely on counter-top air poppers or microwaves to whip up a tasty popcorn snack. But infrared cooking offers another viable alternative, according to a September paper published in the journal ACS Food Science and Technology.

Popcorn is the only grain in the corn family that pops in response to the application of heat—specifically, temperatures above 180° C. It has a lot to do with the structure of the kernels. Each has a tough outer shell, called the pericarp, within which lies the germ (seed embryo) and the endosperm. The latter holds trapped water (popcorn kernels need about 14 percent water to pop) and starch granules.

Last year, Mahdi Shavandi and his coauthors at the Iran Research Organization for Science and Technology in Tehran successfully demonstrated the proof of principle for their approach to making popcorn with infrared heat. With this method, a heat source like fire, gas or energy waves is in direct contact with the food, rather than a heating element like a pan or grill grate. It's often likened to broiling or cooking food over a campfire. Fans argue that this method is fast, highly energy efficient, and environmentally friendly when compared to more conventional means of heating.

It's already used for such purposes as heating, drying, roasting, cooking, baking, and even microbial decontamination, per the authors. And infrared grills are increasingly popular. But could you use infrared cooking to produce popcorn with all the desirable characteristics we know and love, and convince us to switch from our beloved microwaveable brands? Shavandi et al. thought it might be possible.
