3 Terms and definitions

This standard applies the terminology according to GOST 27186 and [1].

 

4 Types and subtypes

4.1 Wheat are subdivided into types according to sustainable natural attributes associated with its technological, nutritional and commercial properties, and the subtypes of changing the natural characteristics (grain hardness and color) specified in table 1.

4.2 Wheat containing a mixture of wheat grains over other types of standards established in table 1, it is determined as “mix types”, indicating the composition with percentage.

4.3 Wheat all types and subtypes that meets the requirements of this sub-type of the glassiness, but do not meet the requirements for color, refers to the subtype to which it is responsible for grain hardness.

4.4 Wheat, have lost as a result of adverse conditions of ripening, harvesting or storage, its natural color, defined as “darkened” (in the presence of dark shades) or “bleached” with the number of type and subtype.
