Green tea goes nano
A new study has found that greet tea catechins encapsulated in nanoparticles may be released in a controlled manner. In vitro research showed that chitosan nanoparticles had an encapsulation efficiency of over fifty percent and thus a controlled release of antioxidant-rich polyphenols was achievable. Nanotechnology is already being used in food and packaging industries and focuses on altering matter at an atomic or molecular scale. A more effective delivery system could pave the way for a more widespread use of green tea catechins.
