Contaminating microplastics can interact with food proteins in the matrix and during digestion. This study investigated adsorption of chicken egg protein ovalbumin to polystyrene (PS, 110 260 μm) polyethylene terephthalate (PET, 140 MPs acidic neutral conditions alterations structure. Ovalbumin affinity depended on size (smaller > larger), type (PS PET) pH (pH 3 7). In bulk solution, does not change secondary structure significantly, but induces loosening (at 3) tightening 7) tertiary Formed...
Human ingestion of microplastics (MPs) is common and inevitable due to the widespread contamination food items, but implications on gastric digestion proteins are still unknown. In this study, interactions between pepsin polystyrene (PS) MPs were evaluated by investigating enzyme activity conformation in a simulated human environment presence or absence PS MPs. The impact was also assessed monitoring kinetics protein hydrolysis through static vitro cow's milk contaminated with PS. binding...
Abstract: The ongoing use of plastic polymers to manufacture food packaging has raised concerns about the presence nano- and microplastics (NMPs) in a variety foods. This review provides most recent data on NMPs' migration from into milk dairy products. Also discussed are possible effects NMPs nutrient digestion, absorption, metabolism. Different kinds products, including skimmed or whole liquid powder milk, infant formula other have been found contain various sizes, shapes,...
Manufactured nanoplastic particles (NPs) are indispensable for in vitro and vivo testing a health risk assessment of this emerging environmental contaminant is needed. The high surface area inherent hydrophobicity plastic materials makes the production NPs devoid any contaminants very challenging. In study, we produced nanoprecipitated polyethylene terephthalate (PET) (300 nm hydrodynamic diameter) with an overall yield 0.76%. presence ionic surfactant sodium dodecyl sulfate (SDS) was...

High surface area inherent hydrophobicity plastic material, makes production NPs devoid any contaminants very challenging. In study we produced nanoprecipitated polyethylene terephthalate (PET) (300 nm hydrodynamic diameter) characterized presence ionic surfactant sodium dodecyl sulfate (SDS) by 1H NMR. Relative ratio NP/surfactant was...
