Coca-Cola just signed a five-year, $1.1 billion deal with Microsoft. Five years ago, it was discovered that there were fluorescent nanoparticles in Coca-Cola. Now, if I were a conspiracy theorist,
I might think there were more to this partnership. Now, according to reports, Microsoft and the Coca-Cola company have announced a five-year strategic partnership to align Coca-Cola’s core technology strategy system wide. So it is safe to enable the adoption of leading edge technology and foster innovation and productivity globally. Using Azure OpenAI service, Coca-Cola is currently exploring the use of generative AI-powered digital assistance.
Now did you know they have found nanotechnology in Coke and in Pepsi products? Have a look at this.
Foodborne nanoparticles (NPs) are raising significant concerns regarding human health. This research highlights the detection of fluorescent NPs, approximately 5 nm in size, in two widely consumed beverages: Coca-Cola (Coke) and Pepsi-Cola (Pepsi). These NPs consist of hydrogen, carbon, and oxygen—elements known for their adjustable emission properties, with quantum yields of 3.3% for Coke and 4.3% for Pepsi. NMR analysis confirmed the presence of sp3-hybridized carbon atoms associated with alcohol and ether bonds. Notably, these NPs can be absorbed by living cells, leading to accumulation within the cell membrane and cytoplasm.
When evaluating the acute toxicity of these NPs, BALB/c mice appeared healthy after receiving a single dose of 2 g per kg of body weight. While statistical analyses showed some differences in biochemical parameters—such as glutamate pyruvate transaminase (GPT), glutamic oxaloacetic transaminase (GOT), urea, and creatinine—these were not biologically significant, and no apparent organ damage or histopathological abnormalities were noted in the mice. Furthermore, a biodistribution study revealed that the NPs tended to accumulate in the digestive tract but also had the capability to cross the blood-brain barrier, dispersing within the brain. In vitro digestion experiments indicated a notable quenching of fluorescence in the NPs. This study is the first to report the presence of foodborne fluorescent NPs in Coke and Pepsi, offering important insights into their physicochemical properties and toxicity characteristics, both in vitro and in vivo.
