Nanotechnology has long been present at every stage of the food supply chain\u2014from plant growth and livestock feed to the processing, transformation, and packaging of food. Consider agricultural production, which utilizes nanosensors to detect pesticides and nanocapsules to increase efficacy while reducing dosages. On our tables, nanotechnology intervenes to optimize flavor, taste, color, and food texture, as well as to improve the absorption and bioavailability of certain nutrients and supplements. In short, nanotechnology is a powerful ally that must be used consciously in this sector as well. The lingering question remains: is it possible for nanotechnological interventions to pass into or remain in food, and what are the potential risks to the health of the final consumer? Let\u2019s find out together.<\/p>\n\n\n\n

How is nanotechnology applied in the food sector?<\/h3>\n\n\n\n

To provide a complete and accurate picture, we must emphasize that we have always dealt with entirely natural nanocompounds in our daily diet. The size of proteins, oligosaccharides, vitamins, and all the nanovesicles that our body produces for proper functioning\u2014including during nutrition\u2014are proof of this. In practice, humanity has interacted with nanoparticles since the invention of grain milling, which includes the entire category of flours. Finally, coming to the present day, think of the most common sauce paired with a plate of French fries. Yes, mayonnaise is, for all intents and purposes, a nanoemulsion.<\/p>\n\n\n\n

How do nanoparticles modify food?<\/h3>\n\n\n\n

It is important to become aware of what is in our food: many of the organoleptic and nutritional characteristics that define major food categories are actually nanoformulations of additives. Don’t believe it? The fluidity of creams or the crunchiness of biscuits is achieved thanks to nanocompounds. The brilliant coloring of yogurt and glazes or the glossiness of chocolate can be the result of nano-ingredients. Even low-calorie products with a creamy appearance, or those low in salt or sugar yet sweet and savory to the palate, as well as dietary foods that induce satiety, are the result of adding nano-additives.<\/p>\n\n\n\n

Medicine and nutraceuticals are also involved in the search for better additives. Recent studies have proposed using iron nanoparticles mixed into food, which could be more accessible at a cellular level, helping to treat various forms of anemia. Omega-3 fatty acids from fish oils, which are often unpleasant to the taste, can be nano-encapsulated to hide their flavor and promote assimilation. But nanotechnology is not strictly limited to the food itself.<\/p>\n\n\n\n

How is nanotechnology used in food preservation?<\/h3>\n\n\n\n

It\u2019s not just about the food. Nanotechnology finds an interesting and highly advantageous use in food packaging. Nanotechnology in packaging allows for a significant increase in the quality with which food can be preserved in an optimal state. Here are some examples:<\/p>\n\n\n\n
