    Cool Scientists Discover why some Popcorn Kernels Don't Pop

    Hi to all

    Well we can all relax now...nepenthe excepted. There goes His Condo in Florida

    INDIANAPOLIS (AP) - Eat your way to the bottom of almost any bag of popcorn and there they are: the rock-hard, jaw-rattling unpopped kernels known as old maids.

    The nuisance kernels have kept many a dentist busy, but their days could be numbered: Scientists say they now know why some popcorn kernels resist popping into puffy white globes. It's long been known that popcorn kernels must have a precise moisture level in their starchy centre - about 15 per cent - to explode. But Purdue University researchers found the key to a kernel's explosive success lies in the composition of its hull.

    It turns out there is an optimal hull structure that allows kernels to explode, and leaky hulls prevent the moisture pressure buildup needed for kernels to pop.

    "They're sort of like little pressure vessels that explode when the pressure reaches a certain point," said Bruce Hamaker, a Purdue professor of food chemistry. "But if too much moisture escapes, it loses its ability to pop and just sits there."

    He and his associates compared the microwave popping performance of 14 Indiana-grown popcorn varieties and examined the crystalline structure of the translucent hulls of both the popped kernels and the duds.

    In the varieties popped, the percentage of unpopped kernels ranged from four per cent in premium brands to 47 per cent in the cheaper ones.

    The findings could be good news for people who savour the snack and those who grow the 17 billion quarts of popcorn sold each year in the United States.

    Wendy Boersema Rappel, a spokeswoman for the Chicago-based Popcorn Board, said popcorn processors are always looking for ways to improve their product, including reducing the number of old maids.

    "It's one of life's annoyances - it's not rocking anyone's world, but our members always like to improve their product," Rappel said.

    Hamaker said two popcorn manufacturers have already expressed interest in Purdue's findings.

    The research, funded by Purdue's Whistler Centre for Carbohydrate Research, which Hamaker directs, has been published online and will appear in the July 11 edition of the journal BioMacromolecules.

    Any they can't find a cure for the common cold. Why???? Because popcorn is more important.

    I agree total waste of time and money..which I'm sure my taxes paid for something perhaps someones drink while testing all that popcorn.
