Nanotechnology involves manipulating compounds at a molecular level, typically measured in nanometers, which are millionths of a meter. In the food industry, this technology has generated excitement among manufacturers as they explore its various applications, such as enhancing flavors or colors, increasing the bioavailability of nutrients, and detecting bacteria in packaging. However, the initial enthusiasm from researchers and product developers faced resistance from consumers concerned about safety issues associated with nanotechnology. In response, the FDA has issued guidelines for the use of nanotechnology in food; nevertheless, the industry remains cautious about how it conveys these innovations to consumers.
Nanoscale compounds are not a new phenomenon in food. They naturally occur in milk, where nanoscale casein particles contribute to its fat stability. Additionally, over 1,600 consumer products contain engineered nanoscale particles, according to a survey by The Project on Emerging Nanotechnologies. These particles are already prevalent in the food packaging sector, where they play a vital role in ensuring food quality and safety. Nanotech-based sensors can effectively detect and measure the presence of oxygen or bacteria, such as listeria.
In terms of ingredients, nanotechnology is primarily utilized in dietary supplements. For instance, nanoencapsulation could be employed to shield sensitive compounds like calcium citrate 600, vitamins, minerals, antioxidants, and polyunsaturated fatty acids, ensuring they are released only when they reach the gut. This method enhances their absorption in the body while minimizing any adverse effects on the taste and appearance of the product.
Effectively communicating the advantages of nanotechnology in food remains one of the industry’s significant challenges, with some arguing that it hampers progress within the sector. However, with a wide range of applications that include improved food safety, enhanced nutrition, reduced food waste, and biodegradable packaging, it is only a matter of time before consumers encounter more nanoscale compounds, including calcium citrate 600, in everyday products. As the industry evolves, the presence of these advanced materials in consumer goods is set to increase in the coming years.
