Detection of Microplastics in Beer Packaged in Aluminum Cans via FT-IR Technology
AI summary Read the abstract
Researchers used FT-IR spectroscopy to detect microplastic particles in beer packaged in aluminum cans, finding that polymer coatings used in can manufacturing can shed plastic particles into the beverage. This is relevant to human microplastic exposure through food and drink, adding to evidence that beverage packaging is a dietary source of microplastic ingestion.
Čestice mikroplastike su sveprisutne u hrani, piću i okolišu. Izloženost prisutnosti ovim česticama u hrani i piću sve se više istražuje. Pakiranjem piva u aluminijske limenke osigurava se trajnost proizvoda u senzorskom i fizikalno-kemijskom smislu, no različiti polimerni premazi koji se koriste u proizvodnji limenki mogu biti izvori čestica mikroplastike. Cilj ovog rada je istražiti prisutnost čestica mikroplastike i kemikalija povezanih sa tim česticama u pivu koristeći FT-IR tehnologiju. Današnja tehnologija detekcije mikroplastike oslanja se na semi-kvantitatvnu analizu pomoću infracrvene spektroskopije Fourierovom transformacijom. Analizira se transmitanca (T) naturalnog uzorka korištenjem oslabljene ukupne reflektancije (eng. Attenuated Total Reflectance, ATR), te se frekvencijski odziv uzorka koristi za pretraživanje baza referentnih kemijskih spojeva s ciljem pronalaska najboljih podudaranja. U istim uzorcima bile su određene i kemikalije povezane sa česticama mikroplastike, čija analiza je odrađena pomoću GC-MS-a. Analiza je odrađena na pivima proizvedenim i pakiranim u Republici Hrvatskoj, a pakiranim u aluminijske limenke.
