. Based on its amphiphilicity OSA-starch is used as an emulsifier and stabilizer in many food or oil-in-water systems cosmetics and pharmaceutical products 1922. The ultrasonic ultrasonic power that carries out esterification that mixes is 180200W and the time is 1525h. 1 It is used to treat gum arabic 1 and also in waxy maize.

Properties of octenyl succinic anhydride OSA modified starches and their application in low fat mayonnaise. The aim of this research was to modify gelatin GT with 2-octenyl succinic anhydride OA and gallic acid GA and investigate its functionalities. The pores and channels within porous starch.

Molecular Formula C 12 H 18 O 3. O- Succinyl-O-methylpolyethylene glycol 2000 Polyethylene glycol 2000 monomethyl ether succinate. The physical properties of octenyl succinic anhydride OSA starches prepared from rice wheat and potato starches were studied.

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. Pearl millet starches were modified at pH 80 using 30 octenyl succinic anhydride OSA and their pasting rheological properties and in vitro digestibility were analyzed. After neutralization adjusting PH the PH of mixing solutions is 6062.

The degree of substitution DC of OSA-modified starches varied from 0010 to 0025. GT modified with OA GT-OA has an improved water solubility at room temperature and an enhanced surface activity foaming capacity and pH buffering ability. 328152 C at 760 mmHg Molecular Weight.

Starch sodium octenyl succinate and starch aluminium octenyl succinate. The amylose content decreased after modification while the reverse was observed for swelling. For instance starches esterified with octenyl succinic anhydride OSA have been used in the food industry for more than half a century.

This colorless solid is the acid anhydride of succinic acid. 1-Octenyl succinic anhydride not to exceed 3 percent followed by treatment with a beta-amylase enzyme that is either an approved food additive of is generally recognized as safe Limited to use as a stabilizer or emulsifier in beverages and beverage bases as defined in 1703n3 of this chapter. Succinic anhydride is an organic compound with the molecular formula CH 2 CO 2 O.

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. Starch is esterified with octenyl succinic anhydride OSA to yield a hydrocolloid with amphiphilic properties octenyl succinylated starch OS-starch. 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.

Interest in these products has grown in recent years as a result of new methods and applications becoming available. Due to the new hydrophobic groups introduced OSA modified starches OS-starches with amphiphilic properties show useful stabilizing encapsulating interfacial thermal nutritional and rheological properties 6. The main objective herein was to partially characterize modified starches from Dominico-Harton plantain and FHIA 21 planted in Colombia.

Due to a combination of OSAs hydrophobic and steric contribution and starchs. Octenyl succinic anhydride can be used to esterify Starch to yield a hydrocolloid with amphiphilic properties octenyl succinylated starch OS-starch. The amphiphilicity of octenyl succinic anhydride OSA-modified starch is improved due to the introduction of dual functional hydrophilic and hydrophobic groups.

Octenyl succinic anhydride OSA modification affects interaction between molecules on the outer surfaces of two starch granules by altering molecular structures on the outer surfaces. Contact Us for a Quote Now. OS-starch finds wide application in the food industry mainly as emulsifier encapsulating agent and fat replacer.

Except where otherwise noted data are given for materials in their standard state at 25 C 77 F 100 kPa. Chemical modification with octenyl succinic anhydride OSA helps to control the physicochemical and thermal properties of isolated starches. Used for the manufacture of cleaning products as surfactant - hydrotrope.

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. 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. Octenyl-succinic anhydride OSA-modified starch was used as an emulsifier in oil-in-water emulsions.

Regarding antioxidant activity GT-OA. Ad Chemical Biochemical Products Kits Used in Scientific Research. 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.

The addition of octenyl succinic acid anhydride is 1215 of starch quality. Wheat starch WS corn starch CS waxy corn starch WCS potato starch PS sweet potato SP rice starch RS and kidney bean KB were modified using octenyl succinic anhydride OSA and evaluated for various properties. Octenylsuccinic acid is a manufactured ingredient in foods.
