The observations were similar to the granular damage observed by Baldwin et al. in case of ball milled potato starch. In Fig. 1 b, c, the granules observed were more regularly shaped, smooth surface with lesser evidence of cracks indicating that the extent of damage in roller mill was very less as compared to that of chakki/stone mill.

The reduction in final viscosity (FV up to 4770 mPa s), particularly for the refined flour fraction (volume median diameter, D50 . 140 µm), evidenced the poor capacity of damaged starch to bind water during heating step. In comparison with native flour, the modified flours presented higher values of damaged starch (DS %), and ...

Starch's crystalline structure and gelatinization temperature might facilitate or hinder its use. Ball milling has frequently been mentioned in the literature as a method for reducing starch size and as a more environmentally friendly way to change starch, such as by increasing surface area and reactivity, which has an impact on other starch properties. In this study, starch samples were ...

There needs to be more information concerning the effect of different milling methods on the physicochemical properties of wholegrain mung bean flour. Therefore, the physicochemical properties of whole grain mung bean flour were analyzed using universal grinders (UGMB), ball mills (BMMB), and vibration mills (VMMB). The results showed that the particle size of the sample after ultrafine ...
