Insights into the multiscale structure and pasting properties of ball
The effects of ball-milling on the pasting properties of waxy maize starch (WMS) and waxy rice starch (WRS) were investigated from a multiscale structural view. The results confirmed that ball-milling significantly destroyed the structures of the two waxy starches (especially WMS). Specifically, bal …

Improvements to laboratory-scale maize wet-milling …
The wet milling of maize is difficult to study in the laboratory because some of the required separation steps are challenging to implement at bench-scale. This work was conducted to develop an improved 100-g wet-milling procedure that better models the industrial process. Several separation steps were modified from previously reported …

What is Wet Grinding Process | Wet Ball Milling Method …
The Wet Milling Method: A Deep Dive. Wet milling, a core aspect of the wet grinding process, involves breaking down materials in a liquid medium. The wet ball milling process, a popular choice in many sectors, employs a ball mill to achieve a fine grind. This method is particularly effective for materials that are too hard for standard milling.

Effect of ball-milling on the physicochemical properties of maize
3.2. Cold-water solubility of maize starch. The effect of ball-milling time of maize starch in either a ceramic or stainless steel pot on CWS is shown in Fig. 1. Results showed that the longer the milling time, the greater the CWS. Interestingly, the CWS of maize starch increased quickly through the first 3 h of milling but then slowed thereafter.
