Response surface methodology for evaluating the degradation of natural Canthaxanthin by temperature

Response surface methodology (RSM) was used to consider the stability of natural canthaxanthin extracted from Dietzia natronomnaea HS-1 in different situation. Central composite design (CCD) and RSM were applied to optimize the effect of different situations on degradation of natural canthaxanthin – enriched oil-in-water emulsions (o/w) containing vegetable oil (5%), Arabic gum (5%) and Potassium sorbate (0.5%). The effect of different temperature (4, 24, 44°С) and time treatment (3, 18, 33 days) on canthaxanthin was investigated. The regression coefficients obtainedfor amount of canthaxanthin (C), L*, a* and b* respectively were 99.27%, 94.49%, 97.98%, 92.40% and also predicted values were significantly correlated with experimental values.
