A new biotechnology platform developed in Brazil could reshape food safety practices across the protein and dairy industries. HYH Biotechnology has unveiled antimicrobial peptides that, in laboratory tests, controlled Salmonella within two hours and prevented new bacterial colonies from forming for more than four days.
Tackling Foodborne Pathogens
The technology’s performance against Salmonella is particularly significant given the bacterium’s role as a leading cause of foodborne illness worldwide. In addition to free‑floating microorganisms, the peptides achieved approximately 95% degradation of biofilms — the protective structures that allow bacteria to cling to surfaces and resist conventional cleaning.
HYH’s platform was also designed to combat other pathogens of concern, including Escherichia coli and Listeria monocytogenes. Both are frequently linked to outbreaks in ready‑to‑eat foods and animal protein production. The company envisions applications across slaughterhouses, hatcheries, poultry farms, dairies, and egg‑processing facilities.
Innovation Through Molecular Engineering
The peptides were created through four years of research combining bioinformatics, computational modeling, peptide engineering, and experimental validation. Unlike approaches focused on a single antimicrobial molecule, HYH developed a platform of rationally designed peptides, allowing tailored solutions for different industrial needs.
Co‑founder and researcher Renata Rosa emphasized the practical focus of the project: “Our objective has always been to develop a technology capable of solving real challenges in the industry. Beyond producing scientific knowledge, we seek to create solutions that can be transformed into products to increase microbiological safety and contribute to more efficient and sustainable production.”
Economic and Regulatory Impact
Food contamination carries heavy financial risks. A study cited by HYH notes that the average direct cost of a single recall can reach USD 10 million, excluding reputational damage and consumer trust. By reducing contamination risks, peptide‑based biosafety tools could help companies avoid costly disruptions and meet international market requirements.
The technology is protected by a patent, giving HYH the ability to develop exclusive products for different segments of the food industry. Rosa underscored the broader implications: “When we talk about food safety, we are talking about protecting consumers, preserving the reputation of companies, and avoiding losses that can compromise an entire production chain.”
As industrial validation advances, HYH’s peptide platform could become a new line of defense against increasingly complex microbiological challenges. If successful, it may strengthen hygiene protocols, reduce cross‑contamination risks, and position Brazil as a leader in peptide‑based food safety innovation.
