<\/h2>\n

The combination of HPP and natural additives ensures safety and extends the shelf life of plant-based burgers. A recent study shows that this synergy improves pathogen control, prolongs freshness, and allows for lower pressure levels, resulting in energy savings. Thanks to these benefits, HPP stands out as one of the most promising technologies for the gentle preservation of plant-based meats.<\/strong><\/p>\n

The Growing Need<\/h2>\n

Plant-based meat alternatives are booming, but like traditional beef burgers, they face food safety and shelf-life challenges. Both matrices are vulnerable to Listeria monocytogenes<\/em> and spoilage organisms during extended refrigerated storage. Consumers demand clean-label solutions, making innovative preservation strategies essential.<\/p>\n

The Approach<\/h2>\n

Researchers from the University of Reading<\/strong><\/a> (UK) and the University of Burgos<\/strong><\/a> (Spain) recently investigated the use of High Pressure Processing (HPP) combined with nisin (500 IU\/g) or blueberry powder (4%) to improve safety and shelf life in beef and plant-based burgers. Both additives are clean-label solutions. Nisin is a GRAS-approved bacteriocin (i.e.<\/em> a natural antimicrobial peptide produced by probiotics such as Lactococcus lactis<\/em>). The blueberry powder is derived from juice industry byproducts, aligning with sustainability standards.<\/p>\n
