Survey on Phthalates in Beer Packaged in Aluminum Cans, PET and Glass Bottles
AI summary Read the abstract
Researchers surveyed phthalate concentrations in beer packaged in aluminum cans, PET bottles, and glass bottles. The study found varying levels of six different phthalate compounds across packaging types, highlighting that phthalates can migrate from packaging materials into beverages and that microplastic particles may serve as additional vectors for these endocrine-disrupting chemicals.
Phthalates are known as endocrine disruptors and are common in plastic polymers, varnishes, and printing inks. However, they most often enter the human body through food. Plastic materials that hold food contain different chemicals, and phthalates are one of them. Phthalates can also be found in microplastics since microplastic particles serve as a vector for different chemicals that can be slowly released into food and beverages. The aim of this preliminary study was to determine the concentration and types of phthalates (dimethyl phthalate, diethyl phthalate, diisobutyl phthalate, dibutyl phthalate, bis (2-ethylhexyl) phthalate, di-n-octyl-phthalate) in beer packaged in aluminum cans, PET, and glass bottles. Ten aluminum-canned beers, sixteen PET-packaged, and eighteen glass-bottled beers were bought at a local food store and subjected to GC–MS analysis to quantify and qualify phthalates. The results indicate that PET-packaged beers can contain significant amounts of phthalates; in sample P10, the total sum of phthalates reached 219.82 µg/L. Especially high concentrations of dibutyl phthalate were found in all samples, but the highest concentration was detected in sample P13 at 92.17 µg/L. However, canned beers showed even higher levels of certain phthalates, such as bis (2-ethylhexyl) phthalate, which amounted to 326.81 µg/L in sample C1. In short, phthalates pose a serious health-concerning problem and should be regarded as such.

Researchers analyzed the polymer types and plastic additives found in the internal coating films of beer cans from 16 countries, identifying potential sources of microplastic and chemical contamination in a widely consumed packaged beverage. The study found variation in coating composition across countries, with implications for food safety monitoring of canned products.
Monitoring of polymer type and plastic additives in coating film of beer cans from 16 countries
AI summary Read the abstract
Researchers analyzed the plastic coating films inside and outside beer cans from 16 countries and found that epoxy resin was the dominant polymer used, along with chemical additives like DEHP and BHT at concentrations up to thousands of nanograms per gram. Environmental samples of degraded metal cans showed one to two orders of magnitude higher additive concentrations than new cans, suggesting corroded metal packaging becomes a significant source of plastic-associated chemical pollution.
Assessment of anthropogenic particles content in commercial beverages
AI summary Read the abstract
Researchers tested 73 commercially available beverages in different containers for the presence of microplastics and other anthropogenic particles. The study found contamination across all beverage types, with beer showing the highest particle counts and water the lowest, suggesting that the type of packaging and production process both influence how many particles end up in the drinks we consume.
