For the past 20 years, Polaris has been working to improve the stability of microalgae rich in Omega 3 in order to offer oils with a unique stability. The patented Qualitysilver® formulation guarantees an optimal stability adapted to your finished product.
WHY STABILIZE OILS?
Highly unsaturated oils are very sensitive to oxidation triggered by oxygen, heat, metals, and water, to name but a few. It is therefore vital that they be protected from oxidation in order to preserve their nutritional, flavour and smell qualities as well as their shelf life.
This process is applied to all oils rich in Omega-3 and Omega-6 polyunsaturated fatty acids, such as:
- Microalgae oils
- Vegetable oils
The QUALITYSILVER® technology developed by Polaris ensures:
- That oils rich in polyunsaturated fatty acids are protected against pro-oxidant factors
- Performance in term of stability: 2 to 5 times more stable depending on oil type
- Optimum preservation of these oils’ nutritional, flavour and smell qualities are guaranteed
- That the shelf life of the polyunsaturated fatty acids and their assimilation are optimized
STABILITY TEST: STANDARDIZED RANCIMAT TEST
The Rancimat test (standard NF EN ISO 6886) allows the stability of different fatty elements to be compared by determining their resistance time to oxidation.
The Qualitysilver® process acts by delaying oxidation. By comparing the induction times (the time by the end of which oxidation starts spreading) of a standard oil* and a Qualitysilver® oil, we are able to demonstrate the improved stability of Elantria® Qualitysilver® oils .
Assessing their stability using the Rancimat test method proves that Elantria® Qualitysilver® oils show stability 2 to 7 times higher than standard oils*.
*Standard oil = oil containing a natural blend of antioxidants (tocopherols)
CONTINUOUS INNOVATION: 5TH GENERATION QUALITYSILVER®
Innovation also means continuous research into the development of the Qualitysilver® stabilisation process in order to strengthen the Elantria® oil protection process with regard to oxidation: a crucial criteria for high quality nutritional oils.
