Preparation and characterization of starch nanocrystals ...
It is revealed that it is possible to obtain starch nanocrystals (SNCs) after a combination of ball milling and 3days of H2SO4 hydrolysis with a yield of 19.3wt% with a shape similar to those acquired by the conventional procedure after 5days of sulfuric acid Hydrolysis. Waxy maize starch was mechanically treated with a planetary ball mill. X-ray diffraction analysis was employed to determine ...
Milling Process of Starch - ResearchGate
Maize starch was mechanically treated by a planetary ball mill at 500rpm for 1, 2 and 3h. The effect of ball-milling treatment on structure and porosity of maize starch granule was studied.
Planetary ball-mill as a versatile tool to controlled ...
The increment of solubility of starch after milling has been observed using other types of mills where the cold water-solubility increases up to 93% using a stirring mill (Huang et al., 2007) or to 74–93% using a rolling-type ball mill (Zhang et al., 2010). Although, these solubilities were obtained after 2 and 100 h of milling, respectively.
Ball-milling treatment effect on physicochemical ...
Physically modified starch can be safely used in pharmaceutical products (Lawal, 2019). Alcoholic-alkaline and ball-milling treatments are the physical methods that induce crystallinity loss in ...
Effects of Ball Milling Processes on the Microstructure ...
To investigate the effect of ball mill treatment of microcrystalline cellulose (MCC) on the rheological properties of MCC-polymer suspension, the structure and physicochemical characteristics of ground samples with different milling time and the rheological behaviors of MCC-starch suspensions were determined and comprehensively analyzed.
Pasting properties of colored rice starch by ball-mill ...
Physically modified rice starch by ball-mill is important for making good quality bread, noodles, and several processed foods. The production of rice flour was done by ball-mill in an industrial scale. The effects of ball-mill treatment on the physicochemical properties of rice starch were investigated. The gel pasting properties of Joseongheugchal employed to ball-mill treatment …
Ball milling: a green technology for the preparation and ...
The effect of ball mill on the morphological and structural features of cellulose has been described by Okajima and co-workers. 20 They treated microcrystalline cellulose derived from cotton linters in a planetary ball mill at 200 rpm for 4–8 hours in dry and wet conditions with three solvents (water, toluene, 1-butanol). They observed that ...
Effect of ball milling on structural and physicochemical ...
Peruvian carrot and cassava starches were ground in a ball mill for 4, 8, 16, and 32 h and their structural and physicochemical characteristics were determined. Results obtained from HPAEC-PAD, GPC, and amylose content indicated a breaking of hydrogen bounds and α-(1 → 6) linkages of the starch molecules after treatment.
Effect of wet ball milling on physicochemical properties ...
Corn starch was physically modified with a ball mill in ethanol. The effect of ball‐milling treatment on particle morphology, particle size distribution, crystalline structure, and pasting property was examined by means of scanning electron microscopy (SEM), laser diffractometer, X‐ray diffraction (XRD), and rapid viscosity analyzer (RVA).
Evaluation of Starch Damage Values Determined ...
Ball milling changes the short-range crystalline order (Morrison et al 1994) and the absorption characteristics of starch (Mok and Dick 1991a), with the degree of starch damage dependent upon the wheat class (Mok and Dick 1991b). In excess water, such as is used with the RFT procedure, ball-milled samples would TABLE I

Pasting behaviour of high impact ball milled rice flours ...
Modified rice flours presented damaged starch contents up to six times higher than that of the control (Table 1). In comparison with other milling methods reported in the literature (Ngamnikom and Songsermpong 2011), the pulverizing effect of planetary ball mill was higher because it affected the starch granular structure (Tran et al. 2011).
The effect of ball milling treatment on structure and ...
Solely for ball milled starch at 2 h these values were highest, S BET, V BJH and D BJH for ball milled starch at 3 h decreased by 21.1%, 7.8% and 12.4% in respect to that for starch at 2 h, respectively. It was likely that changes of the pore characteristic (S BET, V BJH and D BJH) could be controlled by ball milling time.
Effect of Ball Milled and Ultrasonic Sago Starch ...
The resulting slurry of sago starch dispersion was then prepared by two dispersion methods according to Jiang et al.18 with slightly 784 F.M. Mat Suki et al. / Procedia Chemistry 19 ( 2016 ) 782 â€" 787 modification. There were ball milling and ultrasonic. Plenatary ball mill and UP200S ultrasonic processor were used in this study.
Influence of ball milling on the production of starch ...
The nanoparticles of starch were prepared using planetary ball mill (PM100; Retsch, India) with rotational speed of 600 rpm for 5 h. The five numbers of 8 mm zirconium balls were used and the process was stopped for 10 min after each hour. The samples were then collected and stored at −18 °C in polyethylene zip pouches for further analysis.
