1. SENSOR TO DETECT CONTAMINATION:
Researchers have developed a sensor that helps to detect and collect the Listeria monocytogenes present in the food products and prevent them from entering the market and reach the consumers. This type of pathogens can welcome a number of health effects such as diarrhea, fever, vomiting or meningitis. Listeria monocytogenes is the foodborne pathogen, having the highest rate of hospitalization. It basically affects people with weak immunities such as new born babies or pregnant women. The contamination sensor tests cells and group of microorganisms. The cells are then introduced to an antibody after passing them through compressed air and water. If any pathogen is present in the food, it will react with the antibody to give out a fluorescent colour which is detected then by the special camera pre-installed in the sensor.
2. ANTIMICROBIAL PACKAGING:
Another useful nanotechnology application in the food industry is the antimicrobial packaging. Some of the nanoparticles and nanocomposite are recognized with antimicrobial features which are now used in food packaging industry. Nanocomposites are highly effected because of their surface-to-volume ratio and surface reactivity of the nanosized composites which is comparatively higher than the micro or macro sized composites. Commonly used nanoparticles in food industry are silver, gold, platinum, titanium, zinx oxide, magnesium oxide, etc. Natural biopolymers and synthetic antimicrobial agents are used as well to include antibacterial properties to the food packaging.
3. IMPROVED FOOD STORAGE SOLUION:
Nanomaterials are already in use to make food packaging products. Such as bottles that are made with special nanocomposites to prevent escape of carbon dioxide which helps to extend the life of carbonated drinks and reduce the cost of making glass bottles. Also silver nanoparticles are used in plastic materials which helps to kill bacteria that develop in the food. Other nanotechnology applications in food industry to be implemented right away is nanosensors which can detect the gasses given out by the food when it starts to deteriorate. The smart packaging changes its colour to warn about the food degradation. Smart plastic films made of silicate nanoparticles help to reduce oxygen inside the packet and keep the moisture intact. Thus, we can see smart nanotechnology in food bringing about new applications for food safety.
4. ENHANCED DELIVERY OF NUTRIENT:
One of the very useful application of nanotechnology in food is the delivery of enhanced nutrients. Most of the nutrients fail to reach our body, as most of our diet consists of packaged food. With the help of this nanotechnology application, essential nutrients can be delivered to the human system with ease. The reduced size of capsules is very effective as it lets the nutrients absorb in the body right away.
5. GREEN PACKAGING SOLUTION:
Scientist has come up with biodegradable food packaging which helps to sustain the nutrients in food and keep it fresh for a long time while being not so rude to the environment. With the help of nanotechnology applications in food, a biodegradable film is being made from starch and clay which are locally available in abundance. The clay is then treated, come out of it is nanoclay which is then mixed with thermoplastic starch.Green technology will help in easy disposal of food packages, also it doesn’t cause any harm to the environment compared to the petroleum-based plastics.Tag(s) : nanotechnology in food, nanotechnoogy, green nanotechnology, ,
