Nanotechnology involves manipulating substances at a molecular level, specifically at scales measured in nanometers, which are billionths of a meter. In the food sector, this technology has generated significant interest among manufacturers due to its potential applications, such as enhancing flavor and color, increasing nutrient bioavailability, and detecting bacteria in packaging. However, initial excitement from researchers and product developers faced resistance from consumers concerned about the safety of these technologies. In response, the FDA has established guidelines for the use of nanotechnology in food, yet the industry remains cautious about how it conveys innovations based on nanotechnology to consumers.
Nanoscale compounds are not a novel concept in food; they naturally occur in products like milk, where nanoscale casein particles contribute to fat stability. Furthermore, an inventory conducted by The Project on Emerging Nanotechnologies reveals that over 1,600 consumer products already incorporate engineered nanoscale particles. These particles are extensively utilized in food packaging to enhance food quality and safety. Nanotech sensors play a crucial role in detecting and measuring the presence of oxygen or bacteria, including listeria. In the area of ingredients, nanotechnology is predominantly applied in dietary supplements. For instance, products like Citracal Extended Release leverage nanoencapsulation technology to safeguard sensitive compounds—such as vitamins, minerals, antioxidants, and polyunsaturated fatty acids—ensuring their release occurs specifically in the gut. This method enhances nutrient absorption while minimizing any adverse effects on the product’s taste and appearance.
Effectively communicating the advantages of nanotechnology in food remains one of the industry’s greatest challenges, with some experts suggesting that this communication gap is hindering sector development. Nevertheless, as applications of nanotechnology expand—from enhancing food safety to improving nutrition, reducing food waste, and creating biodegradable packaging—it is likely that consumers will increasingly encounter nanoscale compounds in products, including those like Citracal Extended Release, in the near future.
