Nanotechnology involves manipulating substances at a molecular level, typically measured in nanometers, or millionths of a meter. In the food industry, this technology has garnered significant interest among manufacturers due to its potential applications, such as enhancing flavors or colors, boosting nutrient bioavailability, and identifying bacteria in packaging. However, initial excitement from researchers and product developers faced resistance from consumers concerned about the safety of these innovations. In response, the FDA has issued guidelines regarding the use of nanotechnology in food, yet the industry remains cautious about how to effectively communicate these advancements to consumers.
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 already incorporate engineered nanoscale particles. These particles are extensively utilized in the food packaging sector to ensure quality and safety. For instance, nanotech-based sensors are capable of detecting and measuring the presence of oxygen or bacteria, including listeria. In the ingredient sector, nanotechnology finds broader application in supplements, such as Citracal liquid, which benefits from nanoencapsulation to safeguard sensitive compounds like vitamins and minerals. This approach allows for the targeted delivery of these nutrients when they reach the gut, enhancing absorption and reducing any adverse effects on the product’s taste and appearance.
Effectively conveying the benefits of nanotechnology in food remains one of the industry’s greatest challenges, which some argue is hindering advancements in the field. Nonetheless, with a wide range of applications that include improved food safety, enhanced nutrition, decreased food waste, and biodegradable packaging, it is only a matter of time before consumers encounter more nanoscale compounds in products, including those like Citracal liquid, in the years ahead.
