Nanotech apply in food

1.     Summarization of nanotech apply in food

Across the agri-food chain, from farm to fork, there is a major potential market for future applications and development in nanomaterials. Research in agriculture has always dealt with improving the efficiency of crop production, food processing, food safety and environmental consequences of food production, storage and distribution. Nanotechnology provides a new tool to pursue these goals.

 

 The application of nanotechnology in food and agriculture is in its nascent stage. However, over the next decade, the use of nanotechnology may increase to encompass such applications as the detection of carcinogenic pathogens and biosensors to enable contamination-free food and agricultural products.

 

In recent years, nanotechnology is becoming increasingly important for the food sector. Several novel applications of nanotechnologies have become apparent, including the use of nanoparticles, such as micelles, liposomes, nanoemulsions, biopolymeric nanoparticles and cubosomes, as well as the development of nanosensors, which are aimed at ensuring food safety. Promising results and applications are already being developed in the areas of food packaging and food safety.

 

The incorporation of nanomaterials into food packaging is expected to improve the barrier properties of packaging materials and should thereby help to reduce the use of valuable raw materials and the generation of waste. Edible nanolaminates could find applications in fresh fruits and vegetables, bakery products and confectionery, where they might protect the food from moisture, lipids, gases, off-flavors and odors.

 

In the food sector, one of the most important problems is the time-consuming and laborious process of food quality-control analysis. Innovative devices and techniques are being developed that can facilitate the preparation of food samples and their precise and inexpensive analysis. From this point of view, the development of nanosensors to detect microorganisms and contaminants is also a particularly promising application of food nanotechnology.
