Biomega Group has released the third in a series of whitepapers on recent research and development work, with the latest paper discussing how hydrolyzed salmon peptides could replace glycerin in semi-moist pet snacks delivering high nutritional protein value and great palatability, alongside other health benefits, the company said.

The study was carried out by Passion4Feed AS — an independent pet food research facility in Norway — using the Biomega-branded salmon peptide product Salmigo Protect L60. Following a thorough investigation, the results concluded that removing glycerin from both cat and dog snacks is possible when using the salmon peptide product as a substitute, Biomega said.

“Glycerine has been touted as an unhealthy ingredient by many pet owners. Until today, there has been no viable substitute for pet food manufacturers to achieve the same results without adding glycerin as a humectant (hygroscopic substance to keep foodstuffs moist)," Biomega director of research and development Bjørn Liaset said.

“Our groundbreaking technology ... not only works as a substitute for glycerin but also improves palatability while increasing protein value for cats and dogs. In addition, it also offers beneficial gains for pet health, including increased muscle recovery, generation of energy and potential to lower blood pressure,” Liaset added.

Milka Tesla, Passion4Feed chief executive officer, said, “Semi-moist treats include a complex matrix of ingredients, which is often seen as a science in itself, so it’s important to retain the balance of carbohydrates and proteins in the mixture.

“The aim of the study was to reduce the starch, remove glycerin and increase the level of high-quality carbohydrates and proteins to deliver a plasticizing effect. With the combination of 100% natural pea starch and (salmon peptide product), we discovered that glycerin could be replaced in its entirety. This means pet food applications using this combination of ingredients can claim to be 100% natural and highly nutritional,” Tesla said.

Biomega noted that the whitepaper explains the scientific advantages salmon bioactive peptides could have on animal well-being as well as manufacturing benefits. It is available for download for free on the Biomega website.

Biomega Group’s business model is fully sustainable and uses proprietary biotechnology to transform high-quality raw material into premium food and feed ingredients. In its modern food-grade biorefinery in Norway, Biomega produces hydrolyzed salmon proteins (salmon peptides) and salmon oil.
