Nanotechnology involves the manipulation of materials at the molecular level, typically measured in nanometers, or one-millionth of a meter. In the food industry, this technology has generated significant excitement among manufacturers as they explore its potential applications, such as enhancing flavors and colors, improving the bioavailability of nutrients, and detecting bacteria in packaging. However, the initial enthusiasm from researchers and product developers faced resistance from consumers concerned about the safety of these technologies. In response, the FDA has issued guidelines for the use of nanotechnology in food, but the industry remains cautious about how it conveys nanotech innovations to the public.
Nanoscale compounds in food are not a novel concept; they naturally occur in milk, where nanoscale casein particles contribute to fat stability. Additionally, an inventory by The Project on Emerging Nanotechnologies reveals that over 1,600 consumer products incorporate engineered nanoscale particles, which are already prevalent in food packaging to help maintain food quality and safety. For instance, nanotech-based sensors can effectively detect and measure the presence of oxygen or bacteria, such as listeria. In the ingredient sector, nanotechnology is predominantly applied in dietary supplements, including products like CVS calcium citrate, which benefits from nanoencapsulation. This method can protect sensitive compounds—such as vitamins, minerals, antioxidants, and polyunsaturated fatty acids—ensuring they are released only upon reaching the gut. This approach enhances their absorption in the body while minimizing their impact on the taste and appearance of food products.
Communicating the advantages of nanotechnology in food remains one of the industry’s most significant challenges, with some arguing that it is hindering progress in the sector. Nonetheless, given the diverse applications that range from improved food safety to enhanced nutrition, reduced food waste, and biodegradable packaging, it is likely that consumers will encounter more nanoscale compounds, including CVS calcium citrate, in everyday products in the years to come.
