Preparation and stability of the inclusion complex of astaxanthin with hydroxypropyl-β-cyclodextrin

Inclusion Mechanism and Heat Stability of the Complex of 4'-Hydroxychalcone and Hydroxypropyl-β-Cyclodextrin

“…The decomposition process should be that along with the increase of the temperature, HP-β-CD decomposed first and exposed 4'-hydroxychalcone to the heat, 4'-hydroxychalcone melted and degraded almost at the same time under so high temperature. A similar result has been reported by [11]. DSC/TG analysis suggested the heat stability of 4'-hydroxychalcone could be significantly improved by forming inclusion complex with HP-β-CD.…”

Stability and changes in astaxanthin ester composition from Haematococcus pluvialis during storage

“…Several methods have been suggested to improve the stability of astaxanthin (Gouveia and Empis, 2003;Cinar, 2004;Cysewski and Lorenz, 2004;Xu, 2006;Chen et al, 2007;Kittikaiwan et al, 2007;Yuan et al, 2008;Raposo et al, 2012). It has been reported that storing astaxanthin with other compounds to protect against temperature and light, such as β-cyclodextrin, hydroxypropyl-β-cyclodextrin, and chitosan, improves astaxanthin stability (Cinar, 2004;Xu, 2006;Chen et al, 2007;Yuan et al, 2008).…”

Encapsulation of astaxanthin-rich Xanthophyllomyces dendrorhous for antioxidant delivery

“…Chen et al [12] and Yuan et al [13] incorporated astaxanthin within a ␤-cyclodextrin matrix to enhance its stability against high temperature and light. To improve the stability of astaxanthin, some studies proposed the use of chitosan as a delivery system, in which isomerization of the entrapped astaxanthin was inhibited in spite of high temperature and oxygen [14], and its stability was increased [15].…”
