Ad Chemical Biochemical Products Kits Used in Scientific Research. Multiple analytical techniques including size-exclusion chromatography SEC confocal laser scanning microscopy CLSM and laser diffraction particle size analysis were used to determine the structure and emulsification properties of OSA-starch. Starch sodium octenyl succinate and starch aluminium octenyl succinate.
Starches modified with octenyl succinic anhydride OSA have been used in a range of industrial applications particularly as a food additive for more than half a century. The addition of octenyl succinic acid anhydride is 1215 of starch quality. O- Succinyl-O-methylpolyethylene glycol 2000 Polyethylene glycol 2000 monomethyl ether succinate.
Succinic anhydride is an organic compound with the molecular formula CH 2 CO 2 O. Octenyl succinic anhydride can be used to esterify Starch to yield a hydrocolloid with amphiphilic properties octenyl succinylated starch OS-starch. Monoisotopic mass 210125595 Da.
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. 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. 1 It is used to treat gum arabic 1 and also in waxy maize.
Starch is esterified with octenyl succinic anhydride OSA to yield a hydrocolloid with amphiphilic properties octenyl succinylated starch OS-starch. Average mass 210270 Da. In this review instabilities were pointed out where a new kinetic equilibrium was observed in Pickering emulsions assigned to migration and size variations of particles.
The main objective herein was to partially characterize modified starches from Dominico-Harton plantain and FHIA 21 planted in Colombia.
