  text: "The consumption of edible insects (entomophagy) will gain greater significance
    facing the increasing global population, which is suggested to reach 9 billion
    people in 2050 (FAO., 2009). Due to their high amount of proteins, fatty acids,
    vitamins, and minerals insects represent a valuable source of essential nutrients.\r\nWhile
    the consumption of insects is very common in many countries of Africa and Asia,
    there is a far smaller acceptance for entomophagy in Western cultures. Though,
    products such as noodles or burger paddies made from insect meal have a better
    compliance and can already be purchased in some countries of the European Union.
    This processing step however involves the risk of adulteration, because there
    is no more possibility to authenticate the insects once they are ground.\r\nThe
    aim of this study was to investigate whether edible insects could be measured
    and distinguished by MALDI-TOF MS (matrix-assisted laser desorption ionization-time
    of flight mass spectrometry). Therefore, different kinds of edible insects (buffalo
    worms, mealworms, crickets and grasshoppers) were purchased via online shops and
    ground subsequently. The insect powder was extracted by vigorously shaking in
    diluted formic acid and measured by MALDI-TOF MS. The measurement provided reproducible
    as well as specific mass spectra and enabled a precise differentiation of the
    different species."
