A recent research project from India entitled, Presence of Amorphous Carbon Nanoparticles in Food Caramels, suggests carbon nanoparticles (CNPs) have been in certain foods ever since man knew how to use fire and bake breads or cook with sugars. The study, therefore, assumes that since we have been eating certain foods (e.g., breads, jaggery and sugar caramels) for eons, then eating food containing nanoparticles must be safe.
“The CNPs were amorphous in nature; the particles were spherical having sizes in the range of 4–30 nm, depending upon the source of extraction. The results also indicated that particles formed at higher temperature were smaller than those formed at lower temperature,” according to the study. The study suggests CNPs may be very useful for numerous biological applications, as their sources are regular food items.
