Summary: In this study, chitosan-OSA starch PEC was used as a stabilizer for redispersible dry nanoemulsion containing fenofibrate. The dry nanoemulsions were prepared by spray drying and showed improved dissolution of fenofibrate. The formulation variables such as type of stabilizer, starch to oil ratio, PEC formation method, and lactose amount were investigated for their effects on droplet size and drug dissolution.

Summary: The novel amphiphilic agar modified with octenyl succinic anhydride (OSAR) showed higher transparency and freeze-thaw stability, as well as improved emulsion stability and oil loading capacity compared to native agar (NA). With DS values of 0.06 and 0.12, OSAR exhibited increased gel transparency and decreased syneresis, lower interface tension and average molecular weight, decreased thermal stability, enhanced gel springiness, more liquid-like properties with low gel strength, and lower turbidity and melting temperatures than NA.

Summary: Polysaccharides can be esterified with OSA to form derivatives with amphiphilic properties. The aqueous method is a commonly used preparation method for OSA-polysaccharides. The introduction of hydrophobic groups results in OSA-polysaccharides showing improved interfacial properties, emulsifying stability, viscosity, and digestibility.

Summary: In this study, levan from Bacillus licheniformis NS032 was modified with octenyl succinic anhydride (OSA) in an aqueous medium, and the properties of the resulting derivatives were investigated. The optimum conditions for the synthesis reaction were found to be 40 degrees C and a polysaccharide slurry concentration of 30%. The derivatives with degrees of substitution of 0.025 and 0.036 exhibited retained porous structure and better colloidal stability compared to the native polysaccharide. These OSA-modified levans have the potential to be used in new formulations of emulsion-based systems.

Summary: The esterification of high-amylose Japonica rice starch with octenyl succinic anhydride (OSA) improved its functional properties, including decreased relative crystallinity, increased pasting viscosity, swelling power, emulsifying stability, and resistant starch (RS) content. The OSA-modified high-amylose starch could be used as an emulsifier, thickener, and fat replacer in food systems.

Summary: The synthetic mechanism of octenyl succinic anhydride (OSA) modified corn starch (OSCS) and granule shells (OSCs) based on shells separation pretreatment (SSP) was investigated in this study. The SSP process resulted in higher degree of substitution values and lower average molecular weight for OSCs compared to OSCS. Additionally, SSP was found to significantly increase the reaction efficiency of OSA modification process of CS.

Summary: The synthesis efficiency and side reactions of Octenyl succinic anhydride (OSA) starch can be improved by using lipase immobilized on polydopamine magnetic hydrogel microspheres (PMHM) as a biocatalyst. The prepared L-PMHM can be uniformly dispersed in starch slurry, leading to full contact between lipase and starch. L-PMHM exhibits better affinity to the substrate and achieves a higher degree of substitution compared to free lipase. Moreover, L-PHMM can maintain its activity after multiple reuses and can be easily separated from the product.

Summary: This study investigated the effect of moisture level on the physicochemical properties of OSA starch during heat moisture treatment (HMT) pretreatment. Results showed that a higher moisture content led to a decrease in crystallinity and gelatinization enthalpy, as well as surface damage and cracking of the starch granules. However, when HMT was performed with the right moisture content, OSA starch with the maximum DS value and reaction efficiency was obtained. The OSA esterification after HMT-25% MC resulted in the highest DS value (0.0086) and reaction efficiency (35.86%). The H25-OSA starch exhibited good water resistance and high cold water solubility. FTIR analysis confirmed the substitution of hydroxyl groups in HMT starch with carbonyl and carboxyl ester groups of OSA.

Summary: Atmospheric pressure plasma jet (APPJ) pretreatment of cassava starch (CS) followed by esterification with octenyl succinic anhydride (OSA) resulted in improved degree of substitution, reaction efficiency, emulsion stability, and emulsion activity compared to unpretreated CS. Morphological characteristics and crystallinity of CS were changed by APPJ pretreatment, leading to further improvements in properties after OSA modification. This study demonstrated that APPJ could serve as a novel approach to facilitate starch modification with OSA.

Summary: In order to produce stable Pickering emulsion suitable for targeted delivery in the small intestine under stomach acid conditions, the emulsifying ability and pH responsiveness mechanisms of octenyl succinate anhydride modified amylose (OSA-AM) in formless and nanoparticle form were compared. The results showed that OSA-AM nanoparticles exhibited stronger ability to form stable Pickering emulsion compared to OSA-AMs. Additionally, the stability of the Pickering emulsion was found to be dependent on the pH environment, with OSA-AM nanoparticles showing increased stability in acidic conditions.

Summary: This study employed octenyl succinic anhydride (OSA) modification to improve the dispersibility and ice recrystallization inhibition activity of amyloid proteins fibrils (APFs). The modification mainly reacted with the amino groups of APFs without significantly changing their morphology. The modified fibrils had lower pI, carried more negative charges, and were more hydrophobic. The OSA modification showed a pH-dependent effect on the dispersibility of the fibrils, with stronger aggregation at acidic pH values.
