Nanotechnology has been touted as the following revolution in many industries, including nutrient processing and packaging. The applications of nano-based engineering in nutrient industry may include nanoparticulate bringing systems ( e.g. micelles, liposomes, nanoemulsions, biopolymeric nanoparticles and cubosomes ) , nutrient safety and biosecurity ( e.g. nanosensors ) , and nanotoxicity.

FOOD PROCESSING/INGREDIENT TECHNOLOGIES
Nanotechnology has the possible to significantly change both the physical and functional nutrients we eat. It is now imaginable that nutrient scientists can develop ‘smart ‘ nutrients that will react to the organic structure ‘s alimentary lacks and present foods more expeditiously without changing the gustatory sensation or the texture of the merchandise.

NANOTECHNOLOGY IN FOOD Processing
Principle applications are on demand preservatives and synergistic nutrients. Nanocapsules can be incorporated into nutrient to present foods. Addition of nanoparticles to bing nutrient can enable increased soaking up of foods. Applications that are already being tested in new merchandises are to come in the market. Another cardinal application is additives which could easy be absorbed by the organic structure and could increase merchandise shelf life. Nanosized scatterings, emulsions and filled micelles have the advantage that they are non subjected to deposit which gives better merchandise life span and storage. As their size is much smaller than the wavelength of visible radiation, they can be incorporated in clear and crystalline nutrients without doing wateriness. Substances hard to fade out can more easy be absorbed by the organic structure if they are if nanoscale size due to their big surface country. If the active substance is to be protected during storage or transition through the bowels the bing nanotechnology can bring forth perfect protective beds. It is besides possible to orient protective beds to let go of active substances in an “ intelligent ” manner, e.g. caused by a alteration of Ph-value.

New types of membranes including micro and nano-sieves can be applied in nutrient processing. The pores of the screens are in the micron and nanometre scope. They can be used for the filtration of beer or of milk for cheese production.

In future, they may besides be used for fixing water-filled fat colloids to bring forth low fat milk with the same gustatory sensation as full fat milk which could so be used in creamy low fat ice pick. They can besides be used for encapsulating valuable nutrient ingredients such as minerals in a coating of another ingredient to hike take up by the organic structure or to avoid these ingredients being lost during cookery.
Currently, some nutrient additives with nano-ingredients are sold in USA and Germany. These additives may connote that nanoparticles are present in the nutrient. The additives are chiefly aimed at the diet, athleticss and wellness nutrient markets and contain minerals with a nano-formulation, such as Si dioxide, Mg, Ca, etc. The atom size of these minerals is claimed to be smaller than 100 nanometres so they can go through through the tummy wall and into organic structure cells more rapidly than ordinary minerals with larger atom size.
Nano-additives can besides be incorporated in micelles or capsules of protein or another natural nutrient ingredient. Micelles are bantam domains of oil or fat coated with a thin bed of bipolar molecules of which on terminal is soluble in fat and the other in H2O. The micelles are suspended in H2O, or conversely, H2O is encapsulated in micelles and suspended in oil. Such nanocapsules can for illustration contain healthy Omega3 fish oil which has a strong and unpleasant gustatory sensation and merely let go of it in the tummy.
Food and nutrition companies foresee a great trade of promise for nanotechnology in fresh nutrient merchandises. In fresh nutrient, the ingredients which of course occur in nutrient are adapted for better gustatory sensation, digestion or to turn to the specific nutrition demands of particular groups such as babes, aged or patients. Low fat milk, cheese and ice pick with the same gustatory sensation as full fat merchandises have already been mentioned. An ice gel for soft drinks or ice-cream has been developed. The jelly-like ice gel consists of really little ice crystals incorporating even tinier bubbles of C dioxide. The C dioxide bubbles are 1-10 nanometres in diameter, much smaller in C dioxide bubbles in soft drinks. In the oral cavity, the ice gel causes a feeling similar to sparkling tablets.
Not merely the nutrient itself may be adapted, external diagnostic devices integrating non detectors may besides be used to accomplish a diet which is better targeted to the demands of the organic structure of an single consumer. A future consumer may be able to utilize a fast handheld diagnostic device to prove their organic structure ‘s existent demand for specific nutrient ingredients such as minerals and accommodate their diet consequently and, likewise, a diabetic patient could utilize a glucose detector to set up their demand for insulin.

APPLICATIONS OF NANOTECHNOLGY IN THE FOOD INDUSTRY
Nanotechnology has been used in a broad scope of applications such as H2O purification, cell-wall rupture, slow release of nutroceuticals, micro-encapsulation, deodorization, germicides, antimicrobic and fungicidal maps and addition of shelf life. These applications are divided into several classs including nutrient processing, nutraceutical bringing, packaging and safety and detection, in which many different types of stuffs has been used.
