Different starch possess different performance, special characters of starch could be obtained by treating with chemical reaction so as to apply for manufacture in respect that original starch solution is generally instable, sometimes doublemodified starch is inevitable. The preparation of doublemodified starch and its application in the food industry are introduced in this paper.

As an effective physical method for starch modification, ultrasonic treatment can significantly improve the chemical activity and quality of starch, but its mechanism needs to be further investigated. In this paper, ultrasonic-modified cassava starch and octenyl succinic anhydride (OSA)-modified cassava starch with low degree of substitution were prepared under ultrasonic conditions. The effects of ultrasound on the structure and properties of native cassava starch and the quality of OSA-modified cassava starch were studied. The results showed that the crystallinity decreased from 30.7% to 26.4%, the reaction efficiency increased from 62.28% to 66.20%, and other characteristics also changed after 1 min of ultrasonic treatment. While the structure and properties of cassava starch changed differently after ultrasonic treatments for 8 min and 32–60 min. Consequently, these changes showed that ultrasonic treatment had a significant mechanochemical effect on starch granules. The quality of OSA-modified cassava starch was improved significantly and its influence mechanism was analyzed by the mechanochemistry theory. Practical applications During the esterification of starch, the dense arrangement of crystalline regions limits the reaction of esterifying agents with starch granules. This study showed that ultrasound exerted strong mechanical forces on starch granules, which promoted the production of free radicals and increased the free energy of starch molecules. Besides, the increase of mechanochemical active sites in starch granules was conducive to the homogeneous reaction of octenyl succinic anhydride (OSA) and starch molecules. Therefore, the quality of OSA-modified cassava starch prepared by ultrasonic-assisted treatment was significantly improved. This study provides a reference for the application of ultrasonic technology in other fields and also lays a theoretical basis for the industrial development of high performance-modified starch.

In this paper, the general methods of starch modification are discussed. The applications of modified starch in leather making are summarized and the potential applications of the modified starch are considered. Though the studies of the modified starch were focussed on dialdehyde starch that has been used as tanning material in the past, the authors believe that graft starch may be a possible new material in leather making with uses as tanning agent, retanning agent, and finishing agent.

Starch modified with Octenyl Succinic Anhydride is obtained by esterification of OSA and starch. It is often OSA-starch or Starch Sodium Octenyl Succinate. The starch is an excellent modified starch, including the hydrophobic groups of OSA and the hydrophilic groups of starch at the meantime. The research progress of the synthesis and application of starch modified with OSA are introduced, and the development tendencies of OSA-starch are also viewed.

Starch is a complex carbohydrate formed by the repeating units of glucose structure connected by the alpha-glycosidic linkages. Starch is classified according to their derivatives such as cereals, legumes, tubers, palms, fruits, and stems. For decades, native starch has been widely utilized in various applications such as a thickener, stabilizer, binder, and coating agent. However, starches need to be modified to enhance their properties and to make them more functional in a wide range of applications. Porous starch is a modified starch product which has attracted interest of late. It consists of abundant pores that are distributed on the granule surface without compromising the integrity of its granular structure. Porous starch can be produced either by enzymatic, chemical, and physical methods or a combination thereof. The type of starch and selection of the modification method highly influence the formation of pore structure. By carefully choosing a suitable starch and modification method, the desired morphology of porous starch can be produced and applied accordingly for its intended application. Innovations and technologies related to starch modification methods have evolved over the years in terms of the structure, properties and modification effects of different starch varieties. Therefore, this article reviews recent modification methods in developing porous starch from various origins.

Abstract Starch is extensively used in food applications for process convenience and to improve the quality of food products at industrial levels. The contemporary research on starch has created lots of scientific information that provides a base for interventions in food formulations using starch as an active ingredient. The native starch has some limitations, i.e., low swelling and solubility, low thermal resistance, low shear rates, etc. Modification of starch results in altered properties of starch. To modify starch, various modification methods such as physical, chemical, enzymatic, and genetic methods are used which enhances the starch applications at the commercial level. In the physical modification of starch, the chemical structure of starch is not affected while in the case of chemical modification there is an introduction of a functional group in starch granules. The modified starches are used in various industries such as food, pharmaceutical, paper, and textile industries. The purpose of this manuscript is to provide a detailed overview of the physicochemical, morphological, and rheological properties of native and modified starch.

This paper presents basic methods of starch chemical modification, the effect of microwave radiation on the modification process, and the physicochemical properties of starch. It has been shown that the modifications contribute to improvement of the material performance and likewise to significant improvement of its mechanical properties. As a result, more and more extensive use of starch is possible in various industries. In addition, methods of oxidized starch and starch esters preparation are discussed. Properties of microwave radiation and its impact on starch (with particular regard to modifications described in literature) are characterized.
