Food is any substance which contains nutritional value, when consumed they are ingested by the organism
they breakdown to produce energy and sustain life .The energy is produced at the cellular level due to many
pathways. Healthier the food is, more energy is produced to maintain the metabolism of the body. The basic
secret of nanotechnology and food industry is that the cellular level of human cells and food products
components which are of nanoscale and microscale can easily interact with the nanoparticles which
incorporates nanotechnology in all sectors of the food industry which includes, processing, packaging, safety
and security.
