TOCOBIOL® PLUS GP increases more than 150% the oxidative stability
A study conducted by CSIC shows highly favorable results
for TOCOBIOL® compared to other natural antioxidants.
The results of the study conducted by CSIC (Superior Council for Scientific Research) through the Rancimat method, shows that TOCOBIOL® PLUS GP increases oxidative stability up to 153%.
The objective of the study is to compare the antioxidant activity of TOCOBIOL® versus oregano extract and tocopherols in vegetable oils (sunflower oil) at 120°C.
The main conclusions of the study were the following:
- TOCOBIOL® PLUS L-70 clearly shows a higher antioxidant activity when compared to oregano extract and tocopherols. Both products have been tested under the exact same conditions and at the same dose in order to obtain reproducible results.
- The addition of 1,000 ppm and 2.000 ppm of TOCOBIOL® PLUS L-70 increases the oxidative stability of sunflower oil in 103% and 115,6%, respectively, while the same doses of oregano extract and tocopherols only reaches an increase of 18,7% and 20,3%.
- When using a dose of 1,000 ppm TOCOBIOL® PLUS GP stability of sunflower oil increases approximately 64%. It is remarkable that a dose of 2,000 ppm TOCOBIOL® PLUS GP, we can reach an antioxidant activity of 16.2 Rancimat hours, resulting in an increase of stability of the oil of 153%. This shows that using products of our TOCOBIOL® range it can be reached a stability value twice as high as the original value. However this does not occur when using oregano extract and tocopherols, that only reaches an increase of oxidative stability of 20,3%.
