Encapsulation Techniques to Enhance Astaxanthin Utilization as Functional Feed Ingredient.

ABSTRACT: Herein, the effectiveness of astaxanthin (AX) as functional feed ingredient was assessed by enhancing its stability and bioavailability using encapsulation methods. Spray-drying and liposome entrapment were applied to a natural AX source from shrimp by-products, along with two commercially synthetic alternatives. Encapsulated AX formulations were evaluated for their physico-chemical properties, thermal stability, and in vitro performance using RTL-W1, a rainbow trout (Oncorhynchus mykiss) liver-derived cell line. Both techniques achieved high encapsulation efficiency (73-89%) and provided remarkable protection to AX during thermal treatments, maintaining its stability at 80 °C for up to 2 h and at 100 °C for 30 min. Nevertheless, neither encapsulation methods significantly mi
