Physical characteristics of rice quality.

• Length

The length of the paddy grain is variable, even within a variety, because of variation in the length of the awn and the pedicel. It is for this reason that the type of paddy is not determined by the length of the paddy grain but by the length of the brown rice kernel. In threshing, it is important to watch at what point the paddy grain will break off its panicle, because the pedicel should not be a part of the grain, or else it will have a reduced milled rice recovery through the increase of "husk" production

• Dimensions

The dimension of the paddy grain and milled rice kernel play an important role in the determination of grain standards and throughout the processing cycle. This grain dimension is classified according or in relation to the following.

The type of paddy-classified according to the length of the whole brown rice grain.

• Short -paddy with 80 % of the whole brown rice kernels shorter than 5.5 mm.

Unacceptable Grain

• Damaged and Discolored Kernels

Damaged kernels are defined as kernels and pieces of kernels of paddy/rice which are distinctly discolored or damaged by water, insects, heat or any other means. It is difficult to assess damaged and yellow kernels in paddy unless dehulling and whitening is done. The presence of these grains adversely affects the quality of milled products derived from such lots.

• Immature Grain

Immature grains have a husk weight ranging from 30 to 40% of the grain weight. Hence, the presence of excessive amounts of immature grains in paddy lowers milling yield and increases the husk production. Furthermore, immature grains are predominantly chalky and brittle, breaking easily in the process of hulling and whitening, thus reducing both headrace and total milling yield.

• Chalky Grain

Chalk, an opaque area in the rice grain, is an important quality characteristic in rice and occurs most commonly when grains are exposed to high temperatures during development.

Chalky rice decreases the value of rice because of its undesirable appearance and eating quality for consumers.

In some cases, rice is reprocessed several times to obtain the desired quality standards. Once the grains are mixed, it will be extremely expensive to improve the quality through milling.
