In the last decades a noticeable interest has emerged toward the use of octenyl succinic anhydride OSA-starch to improve the long-term stability in such systems. First published on 27th February 2020 Abstract Modified porous starch PS by introducing octenyl succinic anhydride OSA moieties was synthesized successfully which was applied as an emulsion of β-carotene for the first time. 14 For example octenyl succinic anhydride modified starch which is synthesized by esterification between the hydroxyl group of the starch and the carboxyl group.
Among these food-grade biopolymer emulsifiers starches chemically modified by different alkenyl succinic anhydrides possessing the favorable hydrophobicity are suitable to stabilize emulsions. The physical properties of octenyl succinic anhydride OSA starches prepared from rice wheat and potato starches were studied. Rice and wheat OSA starches had significantly higher peak viscosity PV hot paste viscosity HPV and cool paste viscosity CPV but potato OSA starch had only significantly higher CPV relative to the native starch.
