Scientists Solve Riddle of Unpopped Popcorn

Kozar_The_Malignant writes "CNN is reporting that scientists have solved the problem of unpopped popcorn kernels left in a bag or bowl. The short answer is that unpopped kernels have leaky hulls (seed coats) that prevent the buildup of sufficient pressure to cause the pop. The research has been published online and will appear in the July 11 edition of the journal BioMacromolecules. From the article: 'In the varieties popped, the percentage of unpopped kernels ranged from 4 percent in premium brands to 47 percent in the cheaper ones.' So buying the good stuff for home use is probably worth it."

    Not necessarily true. The quality of kernels is of minor concern, major concern is time to market and freshness. Keep your unpopped corn in a sealed container to maintain humidity level and keep it fron drying out. Microwave popcorns aren't all going to be equal, either, as the oil/salt compositions will vary which affect the hulls of kernels. I've found microwave popcorn has a very short shelflife compared to plain kernel corn. Freshly opened popcorn has fewer 'widows and orphans' than older corn, especially corn which has been left exposed to air.

    Like all things, popcorn engineered to look better or pop better in a microwave isn't necessarily your best tasting corn, either. I only buy microwave corn when I feel I need some for within the next few days and usually not just for myself. If eating popcorn at home I'm more likely to air pop some good stuff and put on real butter and use actual popcorn salt (not that table salt which is appearing in cheaper theaters everywhere.)

    I don't have a paper on this anywhere, but I have had considerable experience popping corn, particularly in college where it helped absorb lots of beer. Naturally popcorn which comes in jars is going to fare better than that in plastic bags, but how old the kernels are is the most decisive factor and a higher end popcorn distributor is more likely to have better packaging. A more porous hull is likely to dry out faster or be weakened by contact with hydrogenated oils in any case. Your 4% to 47% is most likely attributable to quality of packaging, how long the product took to get to market and how long it stayed on the shelf (including shelf time at home.) Granted, better advertised brands are more likely to move through distribution and stores than generic brands, which may give it some edge.

    What's more near and dear to my heart, when I shell several zorkmids at the bijou for my greasy paper bag is what the fsck they're putting on the corn. Most of those butter replacements are horrible and concession stands should be required to post a warning that their 'Butter' isn't butter at all but a blended gookum of vegetable oils. There's only one theater left in my area which still uses genuine butter.

      "actual popcorn salt" I had to Google it, but apparently an extra-fine grained salt is used on popcorn, potato chips, and french fries.

      You can find it in many grocery stores, yet. Though in a pinch those fine iodized salt packets at fast food places will do as well.

      I know Morton and Reese's (no relation to the pb cups) are purveyors.

      I used to have an independent theater that went the whole nine yards with popcorn. To start, its air-popped in high-quality olive oil, and placed evenly on a tray so that butter, salt, and flavor additive salts can be placed evenly.

      To top if off, the admission price was cheap, and compensates for this somewhat more expensive popcorn. Admission was about $4, and a large popcorn about $7. Beat famous players $10 admission + sizeof(your.paycheck) refreshments anyday.

      I refuse to even own a microwave. When it comes to popcorn, I can make perfect popcorn on the stovetop in a pan in 4-5 minutes. That's from cold stove to a bowl of piping hot fluffy popped corn. Personally, I like it better cooked in a little oil than from an air popper. I skip the butter but use plenty of sea salt.

      Anyway, microwave corn is a scam. You get very little, it leaves a pasty film on the roof of your mouth, and when I've made it at the office, I find I still have to stand around and watch else it tends to burn. So making it on the stove results in a better product, takes only slightly longer, and shaking the pan while it cooks is much more fun than tapping my toe waiting for the microwaveable junk to be done.

      I'm with you. Both about microwaves and popcorn.

      I've worked in the restaurant business for a combined total of about 12 years. Everything from Dishwasher to General Manager, with cooking, waiting, and bar tending in between. I used to wait tables at the local Olive Garden. The one thing I truly liked about that place was the fact they didn't even have a microwave. Everything we served was really cooked with real heat

      As for the popcorn, microwave is the lowest form of popcorn. Air-popped isn't all that great either. I personally prefer a mixture of peanut oil and clarified butter and sea salt ground really fine with a mortar and pestil

      Most of those "prepackaged" corn and oil things are alright. The oil is pretty much the same stuff we use at my business partner's theatres (he owns five single-screen theatres in Northern WI), and makes better popcorn than straight vegetable oil.

      Preheat your heavy pot (no light, thin walled or tefloned stuff, to about 250 to 350 with the oil in it. Add the seeds and swirl to coat all the seeds. This is also a good time to add some salt. Heat the pan to about 460 and use a loose fitting flat lid that lets the steam out. Do not shake up and down, but when the popping starts to slow give it a swirl and some gentle side-to-side shakes, maybe one very light tossing shake. When the popping really starts to slow remove from heat (the heavier the pot, the sooner you should remove heat) Pour into a serving bowl as soon as the popping is basically stopped so you don't burn or over dry the popcorn.

      That's the home version of what good popcorn machines do. My business partner owns several vintage popcorn machines and we sell almost as much popcorn for take out as we do in house at the theatres.

    This was one of the original uses for popcorn, before styrofoam peanuts. My father, who worked at Oakridge on the Manhattan Project told me how they'd receive delicate instruments, packed in boxes of the stuff.

    I use an air popper. It takes almost exactly the same amount of time as microwave popcorn.

    As mentioned, plain kernel corn lasts quite a while on the shelf, if properly stored. With an air popper, I usually get about 3-4 bad-popped kernels, but even they usually have opened up a little. I use the cheapest brand kernels I can buy.

    The best part is the cost. The microwave popcorn with 6 3.5oz bags in it costs the same as a 4lb bag of plain kernels. Also, I can spend my money on better-tasting butters specially designed for popcorn.

    So with an air popper, I get fewer bad kernels, just over three times the amount of corn, and I can control the salt and butter amounts.

    I don't understand why people use microwaves rather than a cheap air popper.

    Just to take this a little more seriously than is due it,

    Is there a formal designation for the type of argument which asserts the undesirability of a given course of action on the basis of its consumption of effort/resources from an imagined "total pool of potential expended effort/resources," as it were?

    It seems that there should be one. I encounter it rather often. I'm sure someone's attributed a name to it.

    For example, as an argument against animal rights: "How can you spend all your time worrying about how the animals are doing, when there are children starving to death in Africa and homeless people dying on the street?

    It's very common as a popular attack on perceived productive courses of action or topics of discourse and there's really no substance to the argument beyond the basic notion that any action aside from one which achieves maximum utilitarian gain is morally defective.

  8. Hot air poppers pop almost all every time by Prune · · Score: 4, Interesting

    An hot air popper I paid $3 for at a flea market leaves at most a couple kernels unpopped from enough corn I put in to make about five liters of popcorn. These never burn popcorn either, since once a kernel pops, it is blown away from the hottest bottom of the machine by the airflow. However leaky kernels are, usually the heat at the bottom will generate pressure faster than can be relieved -- the machine can reach very high temperatures, as I know since I use it to roast coffee beans as well.

    No, it's not urban legend. Well, perhaps back in the Los Alamo days. I was but a mere tad in those days... But a few years ago (10? 15?) our orders for computer equipment began arriving packed in real popcorn instead of those nasty little styrofoam peanuts that seem to cling to everything. I thought (and so did the environmentalists) that it was a GREAT step forward. We even used to eat the stuff, with some trepidation. But they stopped using it as a packing material, because, as you remarked, vermin were chowing down on the stuff, and the packers had the choice of either spraying it with noxious pesticides and incurring the wrath of next-of-kin of inner city victims (and perhaps us), or going back to the styrofoam things. They reluctantly chose the latter. God, I hate those white peanuts!!
