Flour quality parameters

  1. Flour Colour. A very simple way to determine colour differences in different batches of flour is to look at the colour of different types of flour under a sheet of glass.
  2. Absorption Ability. Absorption measures the amount of water that can be absorbed by a given quantity of flour.
  3. Flour Protein.
  4. Flour Moisture.

If there is 4 grams of protein per 30 grams of flour, you need to multiply 4 by the number 100 and then divide by 30 (see example below). This flour has a protein content of 13.33%.

Also question is, how is flour tested to make sure it is safe to use?
