Rimfrost Krill Powder Highly Stable, Studies Confirm

07 Sep 2016 --- New studies from the NOFIMA and Denmark Technical University (DTU), have confirmed the high stability of Rimfrost Pristine krill powder.

The krill powder, created by Norwegian vertically integrated biotechnology company Rimfrost AS, is a natural combination of omega-3 phospholipids, astaxanthin, proteins and peptides and can be used in nutritional applications for humans and animals. 

In a collaboration between NOFIMA and Denmark Technical University (DTU), and with financial support from the Norwegian Research Council, two stability studies have been performed, showing that the krill powder is stable and that minimal degradation takes place.

However, as expected from natural products, the study showed that the krill powder is not inert. The results from NOFIMA revealed that the astaxanthin decreased over time, but, that there was no significant change in the other ingredients when stored at room temperature for two years.

The DTU stability trial was shorter and has recently been published in the European Journal of Lipid Science and Technology. The results confirmed the high stability of the powder and that the overall oxidation and hydrolysis was low. The use of vacuum packaging increased the oxidative stability of the krill powder as determined by higher contents of astaxanthin and Vitamin E.

“This shows that our proprietary and gentle state of the art enzymatic hydrolysis technology results in a krill product with superior quality.” Says. Dr Inge Bruheim, Chief Scientific Officer, Rimfrost AS. 

Henrik Traaholt, VP Sales, Rimfrost AS, said, “Rimfrost Pristine krill powder can be formulated as a stand-alone product or mixed with other dry ingredients into tablets or capsules, thus providing our customers with a range of product combinations and marketing opportunities”.
