Nanotechnology involves manipulating materials at a molecular scale, specifically within the nanometer range, which is one-billionth of a meter. In the food industry, this technology has generated excitement among manufacturers due to its potential applications, such as enhancing flavors and colors, increasing nutrient bioavailability, and detecting bacteria in packaging. However, initial enthusiasm from researchers and product developers faced resistance from consumers concerned about safety issues associated with the technology. In response, the FDA has issued guidelines for the application of nanotechnology in food, yet the industry remains cautious about how to communicate these innovations 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 conducted by The Project on Emerging Nanotechnologies reveals that over 1,600 consumer products already contain engineered nanoscale particles. These particles are commonly used in food packaging to ensure quality and safety. For instance, nanotech-based sensors can accurately detect and quantify the presence of oxygen or harmful bacteria like listeria. In the ingredient sector, nanotechnology is predominantly utilized in dietary supplements, such as Citracal Calcium from Costco, which benefits from enhanced absorption through nanoencapsulation. This technique could protect sensitive compounds—such as vitamins, minerals, antioxidants, and polyunsaturated fatty acids—allowing them to be released only upon reaching the gut. This not only improves nutrient absorption but also minimizes their impact on the taste and appearance of products.
Effectively communicating the advantages of nanotechnology in food remains one of the industry’s significant challenges, with some arguing that this is hindering development in the sector. Nevertheless, with a wide range of applications that promote improved food safety, enhanced nutrition, reduced food waste, and biodegradable packaging, consumers can expect to encounter more nanoscale compounds in their products, including those like Citracal Calcium from Costco, in the near future.
