“…Horse chestnut SNPs (343 nm), water chestnut SNPs (271 nm), and lotus stem SNPs (885 nm) are synthesized using planetary ball milling . The effects of milling time and solid concentration on the SNP size have been investigated . When the solid concentration is the same, the size and polydispersity index of particles decrease with the increase of grinding time.…”

Nanostarch, as a food-grade Pickering emulsion stabilizer, has attracted wide attention owing to its biodegradability, nontoxicity, small size, and large specific surface area. In this review, the preparation, modification, and application of Pickering emulsions incorporating nanostarch are described. At present, methods for nanostarch preparation mainly include acid hydrolysis, acid hydrolysis combined with other treatments, nanoprecipitation, ultrasonication, ball milling, and cross-linking. Nanostarch is a promising Pickering emulsion stabilizer, and its emulsifying ability of nanostarch is significantly improved by hydrophobic modification. The hydrophobicity, charge, size, and content of nanostarch affect the emulsion stability. Future developments in this area of research include the efficient and environmentally friendly preparation of nanostarch as well as the control of its hydrophobicity via modification. Future studies should focus on the digestibility and storage stability of Pickering emulsions stabilized by nanostarch under different conditions.

“…The colloidal phase of all the synthesized SNPs exhibits a narrow size distribution as the suspension's polydispersity index is below 0.7. A suspension of colloidal nanoparticles below a polydispersity index of 0.7 with narrow size distribution and better colloidal stability has been reported [37].…”

In the present study, an intensified approach for the synthesis of starch nanoparticles (SNPs) was demonstrated by using ultrasound-assisted acid hydrolysis method. The conventional acid hydrolysis for the synthesis of SNPs was intensified using ultrasound. The overall time required to convert starch granules to SNPs in the conventional acid hydrolysis method (48 h) was significantly reduced to 45 min by simultaneous acid hydrolysis and ultrasound irradiation. The acid concentration was found to be an important parameter for obtaining the desired size and morphology of the synthesized SNPs. The variation in the surface charges associated with the SNPs was confirmed through measuring their zeta potential. These potential charges on the surface of SNPs induce crystal growth among the synthesized nanoparticles. The irregular crystal morphology at higher acid concentration clearly shows SNPs' attachment with each other by coalescence. The higher crystallinity for SNPs was observed at low acid concentration; however, the lower acid concentration (0.5 M) leads to the smaller particle size of SNPs from 40 to 60 nm, with the overall yield of 23%. The proposed ultrasound method is more efficient and reproducible for the synthesis of SNPs for various applications.

“…Torres et al (2019) showed that the degree of crystallinity of starch nanoparticles produced by the acid hydrolysis of potato starch ranged 40%–60% while the crystallinity of the Andean potato starches ranged 38%–44%. In addition to the chemical attacks, there are physical methods to destroy the native structure of the starch granules, including nanomilling (Patel, Chakraborty, & Murthy, 2016), ultrasonication (Bel Haaj, Magnin, Pétrier, & Boufi, 2013), reactive extrusion (Song, Thio, & Deng, 2011) and gamma radiation (Lamanna, Morales, García, & Goyanes, 2013).…”

Starch is one of the most abundant biopolymers on earth, next to cellulose and chitin (Tharanathan, 2005). It is one of the most important sources of food for humans, and, at the same time, it is also a renewable resource that could potentially be used in many industrial applications. It is found in plant roots, tubers, stalks and seeds, and is produced by staple crops such as corn, wheat and potato (Buléon, Colonna, Planchot, & Ball, 1998). Most of the starch produced worldwide is derived from corn. Other types of starch such as cassava, potato and wheat starch are also produced in large amounts. Only the starches extracted from these crops are commercially important (Zhu, 2020) and have applications in different areas, such as the food, textile and paper industries (BeMiller & Whistler, 2009; Sjöö & Nilsson, 2018). Starch is synthetized in the chloroplast of plant cells as insoluble granules. These granules are formed by two different polymers: amylose and amylopectin. Amylose is a linear, or slightly branched, polysaccharide of glucose units joined by α-1-4 glycosidic bonds (Dimantov, Greenberg, Kesselman, & Shimoni, 2004). Amylopectin is a branched biopolymer featuring additional α-1-6 glycosidic bonds. The botanical source determines a variety of starch properties such as chemical composition, the amylose/amylopectin relation, molecular weight, molecular structure, the length of the α-glucan chains, the branching degree of amylopectin and the amount of non-carbohydrate impurities, as well as other thermal and rheological properties (Nwokocha, Aviara, Senan, & Williams, 2009). Starch is a cheap and versatile biopolymer that has been used for many biomedical applications, including tissue engineering scaffolds, bone cements, drug delivery systems and stent (Beilvert
