- Abstract
- Calcium alginate gel (CAG) beads were used to entrap the antioxidant astaxanthin-rich Xanthophyllomyces dendrorhous (ASX) by ionic gelation. ASX-CAG bead entrapment efficiency and release behavior, as influenced by alginate and CaCl(2) concentration and hardening time, were investigated. The optimized bead preparation conditions that gave rise to an efficient ASX release pattern were 1.5% alginate, 50 mM CaCl(2), and a 5 min hardening time. The antioxidant activity of non-encapsulated ASX was maintained for 4 days and then sharply decreased, whereas encapsulated ASX was maintained for 6 days. These results revealed that physical entrapment of ASX within CAG beads could bean effective technique for protecting the antioxidant activity of ASX from lipid peroxidation. (C) 2011 Elsevier B.V.
