Abstract
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.
Abstract (english)
Microplastic particles are ubiquitous in food, drink and the environment. The exposure and presence of microplastic particles in food and drink is being increasingly investigated. Packing beer in aluminum cans ensures the durability of the product in terms of sensory and physico-chemical terms, but the various polymer coatings used in the production of cans can be sources of microplastic particles. The aim of this work is to investigate the presence of microplastic particles and chemicals associated with these particles in beer using FT-IR technology. Today's microplastic detection technology relies on semi-quantitative analysis using Fourier transform infrared spectroscopy. The transmittance (T) of the natural sample is analyzed using Attenuated Total Reflectance (ATR), and the frequency response of the sample is used to search databases of reference chemical compounds with the aim of finding the best matches. Chemicals associated with plastic microparticles will be determined in the same samples, which will be analyzed using GC-MS. The analysis will be performed on beers produced and packaged in the Republic of Croatia, and packaged in aluminum cans. Beer packaged in a glass bottle will be used as a control sample.
