Bioiberica confirms bioactive peptides in Palbio

Bioiberica, a global life science company, has announced the publication of a scientific paper in the International Journal of Molecular Sciences, confirming the presence of bioactive peptides in Palbio – a hydrolysed porcine intestinal mucosa protein for improved animal nutrition in a media release.

Building on previous evidence of the ingredients’ benefits for animal health and performance, the newly commissioned research validates the hypothesis that Palbio bioactive peptides have specific biological functions – such as antimicrobial, antioxidant, cytokine/growth factor-like, and immunomodulatory activities. According to the company, the new research sets Palbio apart as a science-backed, high-protein functional feed ingredient with tangible benefits for key growth markers, helping pet food, livestock and aquaculture feed producers better support animal health and nutrition. 

For over 25 years, scientific researchers at Bioiberica have been continuously working to define and refine the benefits of the Palbio range for animal nutrition. Palbio is developed with porcine protein obtained through enzymatic hydrolysis in a circular economy model as a coproduct of APIs (Active Pharmaceutical Ingredients). Early macro research demonstrated the ingredient’s status as a palatable and highly bioavailable source of amino acids shown to support metabolism, promote feed intake and generally stimulate growth in swine, poultry and pets, according to the company. Through further studies, it was discovered that Palbio influences the morphology of intestinal cells, selectively promoting their growth over that of other tissues like lung, liver, and kidney, it says. Subsequently, the ingredient was also found to stimulate metabolic regulators in gut cells, particularly those involved in key physiological functions.

Backed by this robust body of evidence, researchers at Bioiberica set out to confirm that Palbio is both rich in free amino acids and contains bioactive peptides with specific biological activities, the company reports. The new study, published in the International Journal of Molecular Sciences, supports this hypothesis, with animals supplemented with Palbio showing evidence of contribution to growth, gut integrity and immune modulation. 

‛This milestone is the culmination of decades of research and trials investigating the potential of Palbio, to show why it can be trusted to deliver results for our customers,’ comments Xavier Garcia, Business Unit Director Animal and Plant Health at Bioiberica. ‛Palbio is not just a high-performance functional feed ingredient with a long-standing reputation for quality – it is now scientifically validated as a source of free amino acids and bioactive peptides that support animal health. Research like this exemplifies how we have approached innovation at Bioiberica for over 50 years: with scientific rigor, complete transparency, and an insatiable curiosity.”
