The principle of nanotechnology in food processing isfocusing more on food preservation and interactive foods.The advantages of nanotechnology in food processing is todevelop the texture of food components, encapsulate foodcomponents or additives, developing new tastes andsensations, controlling the release of flavours and increasingthe bioavailability of nutritional components. On the otherhand, the success of these advancements will be dependenton consumer acceptance and the exploration of regulatoryissues. Food producers and manufacturers could make greatstrides in food safety by using nanotechnology, andconsumers would reap benefits as well[1].Many major areas in food production may benefit fromnanotechnology which is development of new functionalmaterials, microscale and nanoscale processing, productdevelopment and methods, instrumentation design forimproved food safety and biosecurity, storage, transportationand traceability [2,3]. The rapid development in foodindustries improved tastes, colour, flavour, texture andconsistency of foodstuffs, increased absorption andbioavailability of nutrients and health supplements, new foodpackaging materials with improved mechanical, barrier andantimicrobial properties, nano-sensors for traceability andmonitoring the condition of food during transport andstorage[3].
