Nanotechnology involves the manipulation of materials at a molecular level, with dimensions measured in nanometers, or one-millionth of a meter. In the food industry, this technology has captured the interest of manufacturers, who are exploring its potential applications, including the enhancement of flavors and colors, the improvement of bioavailability for nutrients like nature’s bounty calcium citrate, and the detection of harmful bacteria in packaging. However, initial excitement from researchers and product developers faced resistance from consumers concerned about safety issues related to this technology. In response, the FDA has issued guidelines for the use of nanotechnology in food, yet the industry remains cautious about how it presents nanotech innovations to consumers.
Nanoscale compounds are not a recent phenomenon in food; they naturally occur in milk, where nanoscale casein particles contribute to its fat stability. Additionally, over 1,600 consumer products reportedly contain engineered nanoscale particles, as noted by an inventory from The Project on Emerging Nanotechnologies. These particles are already prevalent in the food packaging industry, ensuring food quality and safety. Nanotech-based sensors are capable of detecting and measuring oxygen or bacteria, such as listeria. In the realm of ingredients, nanotechnology is primarily applied in dietary supplements. For instance, nanoencapsulation can protect sensitive compounds—such as vitamins, minerals, antioxidants, and even nature’s bounty calcium citrate—allowing them to be delivered effectively when they reach the gut. This method enhances absorption in the body while minimizing any impact on the product’s taste and appearance.
Effectively communicating the advantages of nanotechnology in food remains one of the industry’s major challenges, with some arguing that this is hindering progress in the sector. However, given the wide-ranging applications that encompass improved food safety, enhanced nutrition, reduced food waste, and biodegradable packaging, it is likely that consumers will encounter more nanoscale compounds, including nature’s bounty calcium citrate, in products in the years ahead.
