“…This means that association between the short-chain glucans is favored both low temperature and long time. Similarly, when glucans released by isoamylase hydrolysis for 24 or 48 h were stored at 4, 25 and 50 °C, the sample at 4 °C storage had the highest yield and the sample at 50 °C had the lowest yield (Lee et al, 2019). This result also indicates that low temperature storage is suitable for chain association, and relatively high temperature (50 °C) increases the mobility of molecules resulting in more propagation process than nucleation.…”

“…However, selfassembly of short-chain glucans did not always match crystallization. According to Lee et al (2019), SNPs obtained at 4 °C showed the highest yields, but SNPs at 25 °C had the highest relative crystallinity from XRD results. This is explained by the fact that fast chain association often forms the amorphous matrix and short chains are rather unfavorable for crystal formation.…”

“…Bule ´on et al (2007) reported that linear glucans form the double helical structures and these structures become ordered domains by different morphological orientations. Various parameters such as starch concentration, hydrolysis time, storage temperature, and time affect self-assembly formation (Cai and Shi, 2013;Lee et al, 2019;Sun et al, 2014a). Sun et al (2014a) reported that the yield of proso millet SNPs increased from 15.29 to 54.66% at 4 °C with increasing self-assembly time from 0.5 to 24 h, respectively.…”

“…Properties of self-assembled SNPs differ according to the composition of the hydrolyzates in the self-assembly process (Fig. 1), which is divided into two cases: (1) using only the supernatant (soluble fraction) after enzymatic hydrolysis (Lee et al, 2019;Qiu et al, 2016;Sun et al, 2014a) and (2) using both the soluble and the insoluble fractions after enzymatic hydrolysis (Sun et al, 2014b;Suriya et al, 2018). In the former case, only the short-chain glucans of low molecular weight participate in the synthesis of SNPs (Table 1).…”

Enzymatic hydrolysis and self-assembly are considered promising methods for preparation of starch nanoparticles (SNPs) because they are environmentally friendly, and time- and cost-effective. These methods are based on the self-assembly of short-chain glucans released from the α-1,6 bonds in amylopectin. Since their discovery, many studies have described the structural and physicochemical properties of self-assembled SNPs. Self-assembled SNPs can be prepared by two methods: using only the soluble portion containing the short-chain glucans, or using the whole hydrolyzate including both insoluble and soluble fractions. Although the structural and physical properties of self-assembled SNPs can be attributed to the composition of the hydrolyzates that participate in self-assembly, this aspect has not yet been discussed. This review focuses on SNPs self-assembled with only soluble short-chain glucans and addresses their characteristics, including formation mechanisms as well as structural and physicochemical properties, compared with SNPs prepared with total hydrolyzates.

“…To improve the efficiency of the reaction, starch is often pretreated to destroy its crystalline structure, enhance the degree of reaction, and improve the performance of the modified starch. The current pretreatment methods include physical, chemical, and biological methods (Gong et al, 2017;Zhang et al, 2017;Chang et al, 2019;Holck et al, 2019;Lee et al, 2019). Compared with the other two methods, biological methods are environmentally friendly and mild in response.…”

Carboxymethyl cellulose, a hydrophobic derivative from cellulose that can be prepared from different biomass, has been widely applied in food, medicine, chemical, and other industries. In this work, carboxymethyl cellulose was used as the additive to improve the hydrophobicity and strength of carboxylated starch film, which is prepared from starch catalyzed by bio-α-amylase. This study investigated the effects of different bio-α-amylase dosages (starch 0.5%, starch 1%) and different activation times (10, 30 min) on starch to prepare the carboxylated starch. The effects of different carboxymethyl cellulose content on the carboxylated starch film were investigated by analysis viscosity, fourier-transform infrared spectroscopy, thermogravimetric analysis, differential scanning calorimetry, x-ray powder diffraction, scanning electron microscope, and contact angle. The results showed that preparing carboxylated starch using activated starch increased the carboxyl content, which could improve the effectiveness of the activated enzyme compared to prolonging the activation time. The carboxyl starch prepared by enzyme catalysis had a lower gelatinization temperature, and enzyme activation destroyed the crystallization area of the starch, thus facilitating the carboxylation reaction. The addition of 15% carboxymethyl cellulose improved the mechanical properties of the prepared film with maximum tensile strength of 44.8 MPa. Carboxymethyl cellulose effectively improved the hydrophobicity of the starch film with the addition amount of 10–30%, while hydrophobic property was stable at 66.8° when the addition amount was exceeded to 35%. In this work, it can be found that carboxymethyl cellulose improve the mechanical and hydrophobic properties of starch film, laying the foundation for the application of carboxylated starch materials.
