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 showed that

Starch damage occurs when the wheat passes between the 2 rollers, which are designed to reduce the size of the particles. The mill setting criterion is purely mechanical. Instead of getting into a complex milling diagram, here are some of the main points: The narrower the gap between the rollers, the more likely the starch will be damaged. The

Ball mill is popularly used for various kinds of starch modification such as corn starch,[7,11,12] cassava starch,[8,13] jicama starch,[13] wheat starch,[14] and rice flour,[15,16] among others. Interestingly, there is no published information available on the effect of ball mill processing for the physicochemical properties of GRS.

damaged starch were different from the native starch granules. The crystallinity of starch granules was negatively correlated (r = -0.992, n = 7) to the damaged starch content;(8) the regression gave zero crystallinity at 94.3% damaged starch.

Starch damage caused substantial decreases in shear stress or apparent viscosity in both waxy and normal maize starch pastes at a wide range of shear rates (5.6 to 400 1/sec). Shear stress or apparent viscosity decreases were more evident in waxy than in normal maize starch pastes at the same ball milling times.

DISCUSSION: The damage of Starch can not be avoided during the milling process. But can be controlled at the mill level. It has a positive influence on the water absorption. It can lead to disastrous results during bread making. The method we used for starch damage determination is simple and quick preparation. Accurate Measurement in less time.

Damaged flour has a tendancy to absorb water like crazy,mine came out very warm out of the electric stone mill , and made the dough too sticky to knead.!! and i believe i know why the wheat has suffered frost. Its color suggest a harsh environment, and when milled, it was so tough , it heated up the stones so much and led to starch damage.
