Note:

No. 1 -wheat flour of the first grade “Alia”; No. 2 – composite mixture of wheat and amaranth flour;

*

a-characteristic of liquefaction reaction rate expressed by the tangent angle to a mixolabogram from the moment of reaching 30°C to C2 point;

**

P – characteristic of starch gelatinization reaction rate expressed by the tangent angle to a mixolabogram withrnC2-C3;

***

Y – characteristic of amylolysis speed expressed by the tangent angle to a mixolabogram within C3-C4.
