Summary
Disposable gloves used in the food industry can release microplastics (MPs). Oil environments significantly increase MP release from polyethylene (PE) gloves, highlighting material choice importance.
Area of Science:
- Environmental Science
- Food Safety
- Materials Science
Background:
- Disposable gloves are extensively used in the takeaway food sector.
- These gloves may leach microplastics (MPs), posing environmental and health concerns.
- Understanding MP release from food-contact materials is crucial.
Purpose of the Study:
- To investigate microplastic release from common disposable food-handling gloves.
- To compare MP release into water versus edible oil food simulants.
- To analyze the influence of glove material on MP contamination.
Main Methods:
- Tested polyethylene (PE), thermoplastic elastomer (TPE), and polylactic acid (PLA) gloves.
- Simulated use by exposing gloves to water and edible oil.
- Quantified released microplastics using microscopy and spectroscopy.
Main Results:
- Oil significantly increased MP release (2-3 times higher than water).
- PE gloves released the most MPs in oil (3183.33 ± 500.83 items/m²).
- TPE gloves showed the lowest release in water (183.33 ± 28.87 items/m²).
- Fibrous MPs were predominant; PE gloves also released granular MPs in oil.
Conclusions:
- Material selection and usage conditions are key to reducing MP contamination.
- Oil-based food simulants enhance microplastic shedding from disposable gloves.
- Further research into safer food-contact materials is warranted.
