Who among us has n’t quick reclaimed a floor cookie when no one was looking ? If nobody ’s seen : it did n’t bechance and it ’s not muddy . Well , not quite .
A newfangled study out ofManchester Metropolitan Universityhas total up with a more nuanced iteration of the strike nutrient rule . Because , if you ’re work to do it , you might as well do it with which food you ’ll be safe(er ) .
The food scientific discipline researches looked at five test food — staff of life with kettle of fish , cooked pasta , a cut of ham , a manifest cookie , and dried fruit — which were leave of on the ground for intervals of three , five and 10 - seconds . These commonly eat foods were selected because of their discrepancy in water - natural process level — water being a key broker in bacteria emergence .
What was found
• food with a high common salt or sugar contentedness , like many work on foods , were less likely to pick up harmful bacteria in so short a period of time . The jambon ( mellow salt ) and sugary lucre and pickle were both consider good , with little sign of bacterial maturation , when retrieved after three second on the dry land . The muddle ’s gamy simoleons subject matter made the slathered slice inhospitable for bacterial development .
• The cooked pasta and dry out fruit , however , both try positive for klebsiella , a bacteria acknowledge to cause a range of disease and infection , as well as flaccid - tissue condition . ( Surprising . You ’d think filth and germs would be more probable to stick by to wettish ham , as compared to dried yield . But it ’s the table salt and nitrates in the jambon , a preserve meat , that protect it from growth of most bacteria . )
• The ironical cookie was also comparatively well off — after three , five and ten seconds — because of its low pee activeness stage and “ adhesion ability ” .
What this means
nutrient made to withstand atomic state of war — sue , box food — are a safer , sugarier , saltier stake . As are cured foods , like ham — which were prepared this way , historically , to keep over prison term unrefrigerated . Makes sense . [ DailyMailviaFoodbeast – Image viaJiri Hera / Shutterstock ]
