A review of the chemical modification techniques of starch

Synthesis, characterization, and antifungal evaluation of novel 1,2,3-triazolium-functionalized starch derivative

“…As the main carbohydrate storage reserve for plants, starch is composed of anhydroglucose units (AGU) linked together by α-glucosidic bonds [1][2][3]. A number of interesting properties such as source universality, renewable, non-toxicity, biodegradable, and biocompatible facilitate a certain degree of applications of starch in biomedicine, biomaterials, and textile areas [4][5][6][7].…”

“…A number of interesting properties such as source universality, renewable, non-toxicity, biodegradable, and biocompatible facilitate a certain degree of applications of starch in biomedicine, biomaterials, and textile areas [4][5][6][7]. Rich in free available hydroxyl groups of anhydroglucose units, starch can be functionalized by chemical modification via introduction of the individual functional moieties to further improve the bioactivities and broaden application scopes of new valuable biomaterials based on starch [1,5,[8][9][10].…”

Starch-protein active films for food preservation

“…Consequently, modified starches can acquire more adequate physicochemical or biodegradable properties. Of all the native starch modification possibilities available, oxidized starches have been reported to show a significant modification in their molecular structure, enhancing the controlled release of active agents entrapped in the starch materials (Masina et al, 2016). Oxidation process of starch is commonly headed for the three available hydroxyl groups which can be substituted through oxidative or substitutive mechanisms, which typically involve a series of reactions, occurring at a suitable temperature and pH value (Balakrishnan and Jayakrishnan, 2005;Li et al, 2011).…”

“…-Chemical modification through esterification, etherification and oxidation (Masina et al, 2016). More information about starch oxidation is detailed in section 1.3.1.…”

“…In this sense, it is currently being targeted in biomedical studies, mainly due to its suitability as a drug delivery carrier (Yu et al, 2007), and in enzyme immobilization applications (Masina et al, 2016). Oxidized starch derivatives are able to form hemiceacetyls/acetyls crosslinked derivatives, leading to reinforced systems with controllable swellability, such as bioplastics and hydrogels (Singh et al, 2007).…”
