Evaluation of the quality of honey produced by bees fed with nanoparticles

Key words:
quality, honey, nanotechnology, nanoparticles.

Summary
Nanotechnology is one of the most dynamically expanding fields of science in modern
world. Its interdisciplinary nature empowers the creation of innovative products that
revolutionize consumer market on daily basis. The manufacturing process based on the use of
nanoscale resulted in development of products with previously undiscovered properties.
Nanoproducts have appeared in the consumer food market and a great example of such
products is honey produced be bees fed with nanoparticles of gold and silver.
The aim of this study was to assess the quality of honey produced by bees fed with
nanoparticles of gold and silver, as well as to evaluate properties of this product in comparison
with honey produced by bees fed in the traditional way. The study included an analysis of the
basis physical and chemical parameters, such as: water content, content of reducing sugars,
sucrose content, total acidity, determination of electrical conductivity, and content of HMF. It
also included sensory analysis and evaluation of antioxidant and antimicrobial properties of
those honeys.
The results of performed research and analysis showed that the basic physical and
chemical properties of honey produced by bees fed with nanoparticles do not differ
significantly from honeys obtained through traditionally fed bees. Their antioxidant activity
was similar to the activity of traditional honeys. However, it was find that honeys produced by
bees feeding with silver nanoparticles have enhanced antimicrobial properties.
