Evaluation of Microplastic Contamination in Table Sugar: What Does Sugar Have Besides Its Sweetness?
AI summary Read the abstract
Researchers analyzed table sugar from sachets consumed in 24 countries and found microplastic contamination in 100 percent of the samples tested. They identified nearly 4,000 microplastic particles across the samples, predominantly filaments made of polyurethane, PET, and polyethylene. The study suggests that sugar is a previously underrecognized source of dietary microplastic exposure and raises food safety concerns about contamination during packaging.
This study evaluates microplastic (MPs) contamination in table sugar packaged in sachets consumed in 24 countries, 18 from Europe, five from America, and one in Asia, emphasizing the ubiquity of MPs in food products. The samples were obtained in a sampling effort involving several people. 100 samples of 3 g of sugar were analyzed (3 replicates each) in a stereoscope with and attached camera, revealing a 100% contamination rate, with 3977 MPs particles identified. Filaments (56.63%) predominated over fragments (43.37%), with blue and black particles being the most frequent. Polymer analysis using Raman spectroscopy identified polyurethane (PU—predominant), polyethylene terephthalate (PET) and polyethylene (PE) as the main types of MPs. Considering estimated dietary intake (EDI) values calculated by EDI = (SgC × MPp)/SM, Brazil and the USA ranked as the countries with the highest levels of total MPs intake. These findings highlight sugar as an important pathway for dietary exposure to MPs, raising critical concerns about the risks to human health and food safety. Regulatory interventions and improved processing protocols are imperative to mitigate MP contamination in sugar and other widely consumed processed foods.

Hidden Pollutants in Food: Evidence of Small Microplastic Particles (100–5 µm) in Refined Sugar from the Italian Market
AI summary Read the abstract
Researchers found microplastic particles (5–100 µm) in refined sugar sold in the Italian market, adding to growing evidence that common everyday foods are a route of human microplastic exposure. The dataset accompanies a study confirming contamination even in highly processed food products, raising questions about how much plastic people inadvertently consume through their diet.
Hidden Pollutants in Food: Evidence of Small Microplastic Particles (100–5 µm) in Refined Sugar from the Italian Market
AI summary Read the abstract
Researchers analyzed samples of refined sugar from the Italian market and detected small microplastic particles ranging from 5 to 100 micrometers in size, confirming that microplastics are present in a widely consumed everyday food product. The findings add to growing evidence that humans are routinely ingesting microplastics through common foods, even highly processed ones like refined sugar where contamination pathways are not immediately obvious. This raises questions about cumulative dietary exposure and the need for food safety standards around microplastic contamination.
Detection and Characterization of Microplastics in Commercial Sugar Types: a New Challenge for Quality Control
AI summary Read the abstract
Researchers investigated the presence, concentration, and potential sources of microplastics in commercially available sugar products using spectroscopic characterization. Microplastics were detected across multiple sugar types, highlighting food-grade sugar as an overlooked route of human microplastic exposure and calling for improved quality control methods.
A spoonful of sugar: human exposure to microplastics through consumption of processed sugarcane.
AI summary Read the abstract
Researchers found tiny plastic bits (microplastics) in both white and brown sugar sold in stores, likely coming from equipment used during processing rather than the plants themselves or packaging. The amounts were surprisingly high, so much so that sugar may expose you to more microplastics than other foods studied so far, including salt, meaning your morning coffee or baked goods could be a bigger source of plastic exposure than previously thought. More research is needed to know exactly how this affects health, but it's a good reason for manufacturers to clean up their processing methods.
RETRACTED: Are there plastic particles in my sugar? A pioneering study on the characterization of microplastics in commercial sugars and risk assessment
AI summary Read the abstract
Researchers analyzed five brands of commercial sugar for microplastic contamination and found plastic-like particles present in the samples. The study characterized the types and sizes of particles found, suggesting that food processing and packaging may introduce microplastics into everyday food products. Note: this paper has been retracted, so its findings should be interpreted with caution.
