Peruvian innovation for a greener future
In a world where plastic pollution represents one of the greatest environmental threats, a team of scientists from the University of Engineering and Technology (UTEC) in Peru has developed an innovative bioplastic from pigmented native potatoes. This pioneering project has the potential to revolutionize the food packaging industry, offering a biodegradable and functional alternative to conventional plastics.
Native potatoes as raw material for bioplastics
The bioplastic developed at UTEC uses a variety of native potato called Kulli papa, created by the National Institute of Agrarian Innovation (INIA) and grown in the regions of Huaraz and Andahuaylas. This potato is rich in starch and anthocyanins, key compounds that provide unique characteristics to this biodegradable film.
Unlike other bioplastics that require the addition of synthetic anthocyanins or those extracted from other sources, this new material integrates both components naturally, making it more sustainable and efficient.
What makes this bioplastic unique?
According to researcher Carolina Parada, leader of the project at UTEC, bioplastic offers benefits that go beyond its biodegradability:
- Freshness indicator: It changes color depending on the pH of the food, alerting about its state of conservation.
- Antimicrobial protection: It helps prevent the growth of bacteria and microbes in food.
- Sustainability: It degrades naturally without leaving contaminating residues, unlike plastics derived from petroleum.
The sheets of this smart film, with dimensions of 30×20 cm, have a purple hue due to the potato used and can change color from fuchsia to green depending on the pH of the packaged food. In addition, they are flexible and semi-transparent, making them ideal for packaging fresh products.
A step towards industrialization
The development of this bioplastic has been validated in packaging for fermented tarwi foods and, after concluding the research in July 2023, a technological package ready for transfer to the industry was presented.
As part of the marketing strategy, the UTEC team has participated in business rounds with the Lima Chamber of Commerce, seeking to connect with companies in the food sector interested in adopting this innovation.
Among the potential benefited sectors are:
- Meat industry: Packaging of meats, sausages and chicken.
- Fruits and vegetables: Preservation of fresh products.
- Dairy and fermented products: Protection of cheeses, tarwi and other processed foods.
The future of food packaging?
Bioplastic made from native potatoes represents a significant advance in the fight against plastic pollution and an opportunity to position Peru as a leader in sustainable innovation in the agroindustry. Now, the big question is: Will companies in the sector be ready to adopt this material in their production processes?
