Bottom Line: The evaluation of astaxanthin stability under various environmental factors reveals that temperature is the most influential environmental factor in astaxanthin degradation.Stability analysis shows that, regardless of the formulation used, the content of astaxanthin encapsulated in alginate beads remains above 90% of the original amount after 21 days of storage at 25°C.These results suggest that the proposed technique is a promising way to enhance the stability of other sensitive compounds.

ABSTRACT
There has been considerable interest in the biological functions of astaxanthin and its potential applications in the nutraceutical, cosmetics, food, and feed industries in recent years. However, the unstable structure of astaxanthin considerably limits its application. Therefore, this study reports the encapsulation of astaxanthin in calcium alginate beads using the extrusion method to improve its stability. This study also evaluates the stability of the encapsulated astaxanthin under different storage conditions. The evaluation of astaxanthin stability under various environmental factors reveals that temperature is the most influential environmental factor in astaxanthin degradation. Stability analysis shows that, regardless of the formulation used, the content of astaxanthin encapsulated in alginate beads remains above 90% of the original amount after 21 days of storage at 25°C. These results suggest that the proposed technique is a promising way to enhance the stability of other sensitive compounds.

Mentions: Fig 1 shows a typical chromatogram for the astaxanthin in this study. The peak in this figure is characterized by a retention time of 5.6 min. The stability of astaxanthin under various environmental conditions was evaluated to determine the effects of the light, temperature, and nitrogen gas. Results show that the minimum loss of astaxanthin, 0.53%, was obtained under a nitrogen atmosphere at -30°C after 16 d. Fig 2 shows that the most influential environmental factor was temperature, as the lowest remaining content of astaxanthin (62.3%) appeared at a storage condition of 25°C after 16 d.
