nanotechnology for food and bio processing industries - suresh neethirajan
DESCRIPTION
Complex set of engineering and scientific challenges in the food and bioprocessing industry for manufacturing high quality and safe food through efficient and sustainable means can be solved through nanotechnology. Bacteria identification and food quality monitoring using biosensors; intelligent, active, and smart food packaging systems; nanoencapsulation of bioactive food compounds are few examples of emerging applications of nanotechnology for the food industry. Background about the potential of nanotechnology; an overview of the current and future applications of nanotechnology relevant to food and bioprocessing industry; and the societal implications for successful implementation of nanotechnology are being discussed in these.TRANSCRIPT
