The chemistry of popcorn: But perhaps not for long. Hamaker is part of a team of scientists at the school who have identified a key crystalline structure in popcorn that appears to determine its popping quality.

The finding could lead to a better microwave popcorn variety with fewer or no unpopped kernels, they say. Manufacturers have tried to reduce the number of unpopped kernels through trial and error breeding of the better performing corn kernels, but the problem persists, especially in microwave popcorn.

Now, science has come to the rescue. Hamaker and his associates analyzed 14 different genetic varieties of yellow popcorn and compared their microwave popping performance.

Experiments with Popcorn

Using the same experimental conditions, they determined that the number of unpopped kernels ranged from 4 percent best to 47 percent worstdepending on the variety.

The researchers then analyzed the properties of the better performing kernels to determine which factors contributed to their outcome.

They found that the key factor that appears to influence popping quality is the chemical structure of the pericarp, or outer hull, which is composed partly of cellulose a polymer of glucose. During heating, the corn pericarp acts like a pressure cooker that locks moisture inside the corn kernel. The heated moisture leads to a pressure buildup until the kernel eventually ruptures and pops, essentially turning the kernel inside out and producing the fluffy white product that we eat.

In the best popping kernels, the pericarp is composed of a stronger, more highly ordered crystalline arrangement of the cellulose molecules than the pericarp of the poorer performing varieties, according to Hamaker and crystallographer Rengaswami Chandrasekaran, one of the team members.

In laboratory studies, the researchers demonstrated that these stronger crystalline structures tend to maximize moisture retention, leading to a more complete rupture and fewer unpopped kernels.

If researchers are successful, the new microwave popcorn could be available to consumers in 3 to 5 years, Hamaker predicts. Although the new popcorn will be slightly different chemically than conventional microwave popcorn, mainly from the presence of more cellulose, it will look and taste just like any other popcorn, he says.Feb 26,  · Popping Fresh.

Popcorn is a type of maize which, unlike other types of corn, pops when heated in oil or dry. It was first found and used to pop by Native Americans thousands of years ago. The kind of popcorn most people pop in their microwaves is the species Zea mays L subsp mays. Based on my research and the results of my experiment, I believe that Orville Redenbacher brand popcorn sells a product containing the perfect thickness of hull and proper.
