Nanotechnology involves manipulating substances at the molecular level, precisely measured in nanometers, or one-millionth of a meter. In the food industry, this technology has generated significant interest among manufacturers due to its potential applications, including the enhancement of flavors and colors, improving nutrient bioavailability, and detecting bacteria in packaging. However, early excitement among researchers and product developers faced resistance from consumers concerned about the safety of these technologies. In response, the FDA issued guidelines for the application of nanotechnology in food, but the industry remains cautious about how it communicates these innovations to consumers.
Nanoscale compounds are not a novel concept 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 indicates that over 1,600 consumer products already incorporate engineered nanoscale particles, particularly in food packaging where they help maintain quality and safety. Nanotech sensors can effectively detect and measure the presence of oxygen or bacteria, such as listeria. In the realm of food ingredients, nanotechnology is predominantly utilized in dietary supplements. For example, encapsulation methods could be employed to safeguard sensitive compounds, such as vitamins, minerals, antioxidants, and polyunsaturated fatty acids, ensuring their release occurs only when they reach the gut. This would enhance their absorption by the body while minimizing their influence on a product’s taste and visual appeal.
Effectively conveying the advantages of nanotechnology in food remains one of the industry’s most significant hurdles, with some arguing that this challenge is hindering progress within the sector. Nevertheless, with a wide array of applications that include improved food safety, enhanced nutrition, decreased food waste, and biodegradable packaging, it is likely that consumers will encounter more nanoscale compounds in products in the coming years. For instance, products like Solaray Calcium Citrate with Vitamin D3 could leverage nanotechnology to enhance nutrient delivery and absorption, further emphasizing the potential benefits of this innovative approach in the food industry.
