“…The intensity ratio of 1041/1015 cm −1 is useful as a convenient index of FTIR data to quantify the degree of order in starch samples. [ 9,18 ] The relative intensities of FTIR bands at 1041 and 1015 cm −1 were therefore recorded from the baseline to the peak height, and the ratios for 1041/1015 cm −1 were calculated. The results revealed that the intensity ratio values of 1041/1015 cm −1 of NGRS, 15m‐MGRS, and 45m‐MGRS films were 0.58, 0.59, and 0.60, respectively.…”

“…[ 10 ] The MGRS was prepared using a planetary ball milling for 15 min (15m‐MGRS) and 45 min (45m‐MGRS) at a speed of 550 rpm, respectively, as previously reported. [ 9 ] The relative crystallinity percentages calculated from the XRD data of NGRS, 15m‐MGRS, and 45m‐MGRS were 37.5, 17.4, and 4.7%, respectively. Sodium carboxymethylcellulose (SCMC; Blanose CMC 7H4XF PH, average molecular weight of 725 000 Da, degree of substitution of 0.7, product code 414711) was purchased from Ashland, Switzerland.…”

[ 9 ] The TA.XT.Plus Texture Analyzer (Stable Microsystems, Godalming, U.K.) equipped with 50 N load cell, a 10‐mm diameter cylinder probe (P10 Perspex), and porcine esophageal mucosa were used. The maximum force required to separate the film from the mucosa (maximum detachment force) and the total amount of forces involved in the film withdrawal from the mucosa (work of adhesion) were calculated using Texture Exponent 32 software (Texture Technologies Corp, Hamilton, MA, USA).…”

“…According to Soe et al. (2020), [ 9 ] the tablets prepared with ball‐milled modified glutinous rice starch (MGRS) exhibited greater mucoadhesive abilities compared to those of hydroxypropyl methylcellulose (HPMC). Although 15‐ and 45‐min milling resulted in MGRS with different levels of crystallinity loss, their tablets and mucoadhesive properties were comparable.…”

This study aims to investigate the physicochemical and mucoadhesive properties of films made of glutinous rice starch (GRS), native (NGRS), and ball‐milled modified GRS (MGRS), in comparison with the reference mucoadhesive polymers. By using the solvent casting technique with glycerol (30% w/w of starch mass) as a plasticizer, all GRS films exhibit satisfactory and comparable thickness and weight uniformity, surface pH, and moisture content. ATR‐FTIR indicates that the hydrogen bonds are formed between GRS and glycerol. The absence of crystalline structure of GRS in glycerol plasticized films is confirmed using ATR‐FTIR and XRD. The films made of NGRS and MGRS have similar swelling behavior (751 ± 75 to 1002 ± 104%), whereas those made of longer milling time MGRS demonstrate higher erosion (27.1 ± 4.2%) (p < 0.05). MGRS films exhibit greater flexibility with lower tensile strength (9.6 ± 1.7 to 9.8 ± 1.0 MPa) but higher elongation (162.5 ± 6.5 to 165.7 ± 2.5%) compared to native systems (13.7 ± 0.5 MPa and 128.1 ± 5.0%, respectively) (p < 0.05). The MGRS films show comparable mucoadhesiveness expressed as detachment force and work of adhesion to those of sodium carboxymethylcellulose, but higher than those of NGRS, hydroxypropyl methylcellulose, and chitosan (p < 0.05). This study reveals the potential exploitation of GRS as a mucoadhesive film former for pharmaceutical application.

The preparation process of resistant starch III (RS3) has attracted widespread attention, but its milling method is often overlooked. This study examines two milling methods for RS3: shear milling (SM) and vibration milling (VM). Manual milling (MM) is used as a control. The particle size, morphology, crystallinity, gelatinization characteristics, and in vitro digestibility of milled RS3 are analyzed. The particle size of the VM‐samples ranged from 71.92 to 107.69 µm, which is lower than SM‐samples. Scanning electron microscopy shows that SM‐RS3 appears as pellets, while VM‐RS3 is mostly coarse flakes. From the results of RVA and DSC, VM destroys more starch than SM. The crystallization peak of VM‐samples disappears, and the retention of SM‐samples is well. The values of R 1047/1022 and R 995/1022 cm−1 indicate that the crystal order and double helix structure of RS3 are destroyed after multiple VM shocked compared with SM. In vitro digestion experiment, resistant starch content of SM‐samples is about 30%, while VM‐samples are much less than SM. These findings suggest that the choice of milling methods has a significant impact on the structure and physicochemical characteristics of RS3, and it is an important step in preparing RS3.
