Sodium caseinate and OSA-modified starch as carriers for the encapsulation of lutein using spray-drying to improve its water solubility and stability.

Bo Zhang Bo Zhang. OSA starch is a chemically modified starch using a starch esterification process by involving octenyl succinic anhydride compound. Selection of appropriate OSA-starch and oil phase is important to ensure that emulsion.

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. This is in agreement with previous studies Previous studies showed corrosive and rough granule surface after OSA modification of sago and maize starches The surface of quinoa starch granules seemed not to be affected. College of Food Science and Engineering Northwest AF University Yangling.

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 chemical modification of starch decreased creaming for months. Based on the data reviewed the ANS Panel had concluded that in humans modified starches such as SSOS E 1450 would not be absorbed intact but would be significantly hydrolysed by intestinal enzymes and then fermented by intestinal microbiota.

Mayonnaises prepared using OSA modified starches were evaluated for phase separation brightness L color index dE and rheological parameters G and G. OSA starch is often utilized. Compared to other natural ingredients such as gum arabic protein and gelatin OSA starches are highly functional consistent.

The pores and channels within porous starch. The amphiphilicity of octenyl succinic anhydride OSA-modified starch is improved due to the introduction of dual functional hydrophilic and hydrophobic groups. Interaction between OSA-modified starches and some ionic components potassium magnesium and calcium as well as hydrocolloids and proteins reduced creaming and coalescence due to dense interfacial film.

OSA groups acted majorly on the surface and caused some superficial pores but crystalline pattern was not significantly altered for all starches. 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. Preparation and properties of OSA-modified taro starches and their application for stabilizing Pickering emulsions In this study the octenylsuccinylated taro starches OSTS with different degree of substitution DS from 0009 to 0032 were prepared and their structural properties such as granule size wettability and morphology were studied.

Preparation of OSA-modified starch The corn starch 30 g dry weight was dispersed in 100 mL of distilled water under gently stirring. 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 starch solution samples were prepared by dissolving the starch granules both the native and the OSA-modified in 50 mL of buffer 5mM phosphate buffer at a pH 70 02 M NaCl and then transferring the sample to an autoclave cylinder.

With non-full substitution of the hydroxyl group with the hydrophobic group OSA starch has amphiphilic and interfacial properties which are soluble in water and some organic solvents. The amphiphilicity of octenyl succinic anhydride OSA-modified starch is improved due to the introduction of dual functional hydrophilic and hydrophobic groups. The chemical modification of starch decreased creaming for months.

A weighed amount of OSA 30 of the dried starch base was added slowly over 2 h while controlling the pH at 875. OSA modified starches enhanced the. Acid-treated starch forms the shell of jelly beans.

Octenyl succinic anhydride OSA-modified waxy starches are used widely as emulsifiers and stabilizers in the food and beverage industry. Starch a large complex branched glucose polymer modified with octenyl succinic anhydride OSA is often used to produce compounds such as emulsion stabilizers and encapsulating agents especially as food additives. The impact of the emulsifier level pH and ionic strength on the rheology microstructure interfacial properties water binding and thermal stability of the HIPE was determined.

The starch blend used in the original dough recipe was partially 5 to 15 replaced with OSA starch. Furthermore the key parameters oil fraction fatty acids composition oxidative stress oil. Interest in these products has grown in recent years as a result of new methods and applications becoming available.

OSA modified starches were used in preparing low fat mayonnaise by substituting 75 fat. The starting material for the dissolved starch was the OSA-modified starch granules prepared as described above. The pores and channels within porous starch provided more possibilities for OSA to modify starch.

The novelties in using OSA-modified starch were also exposed. After OSA modification the normally hydrophilic starch gains a hydrophobic element in the form of octenyl groups resulting in large. OSA modified starches showed higher paste viscosities compared to their native counterparts.

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 19 22. OSA modified starches were used in preparing low fat mayonnaise by substituting 75 fat. A high internal phase emulsion HIPE was firstly fabricated with octenyl succinic anhydride modified starch through simple shear dispersion.
