Abstract
The presence of micro and nano particles of plastic in food products is currently an urgent problem of the food industry and one of the main issues of food safety. However, there are no clear methods for the determination of such particles, nor methods for cleaning food products from them.
Due to the fact that the issue of processing plastic has not yet been resolved, and decaying plastic objects are everywhere around, it is extremely important to study the question of the presence of microscopic particles of plastics (microplastics, MP) in food products, their size and quantity.
In present work for the first time was determined the presence of particles, which can be microplastic, in several vegetable oils using Dynamic Laser Light Scattering method. The size distribution of these particles, their specific surface and zeta potential were determined too.
The content of microparticles in vegetable oils was calculated. It ranges from 2.5 to 9 billion particles per 1 liter of oil. It has been suggested that a possible reason for the presence of such particles in this type of food product is that they may be extracted from slowly breaking plastic containers.
The value of the zeta potential calculated by the device on the basis of data on the movement of particles is in the range from 20 to 30 mV. This means that the microparticles in suspension are stable and not prone to coagulation. Thus, self-cleaning from them is impossible.
