Nanotechnology involves manipulating substances at a molecular level, specifically at dimensions measured in nanometers, or millionths of a meter. In the food sector, this technology has generated considerable interest among manufacturers due to its potential applications, such as enhancing flavors and colors, increasing the bioavailability of nutrients, and detecting bacteria in packaging. However, initial excitement from researchers and product developers faced resistance from consumers concerned about the safety of nanotechnology. In response, the FDA has issued guidelines for the use of nanotechnology in food, yet the industry remains cautious about how to effectively communicate these innovations to consumers.
Nanoscale compounds are not a recent phenomenon in food. They naturally occur in milk, where nanoscale casein particles contribute to fat stability. Furthermore, an inventory conducted by The Project on Emerging Nanotechnologies revealed that over 1,600 consumer products contain engineered nanoscale particles. These particles are already prevalent in the food packaging industry, enhancing food quality and safety. For instance, nanotech-based sensors can detect and quantify the presence of oxygen or harmful bacteria like listeria.
In the ingredient sector, nanotechnology is predominantly employed in dietary supplements, including products like Citracal Plus D3. This is due to its potential for nanoencapsulation, which can safeguard sensitive compounds—such as vitamins, minerals, antioxidants, and polyunsaturated fatty acids—ensuring they are released only when they reach the gut. This method not only improves nutrient absorption but also minimizes any adverse effects on a product’s taste and appearance.
Effectively conveying the advantages of nanotechnology in food remains one of the industry’s most significant hurdles, and many believe this is hindering progress in the field. Nevertheless, with a range of applications extending from enhanced food safety and improved nutrition to reduced food waste and biodegradable packaging, it is only a matter of time before consumers encounter more nanoscale compounds in their everyday products, including supplements like Citracal Plus D3, in the near future.
