What are the three criteria that a miller has to consider?
The quality of flour is determined by the wheat from which it is milled and the efficiency and skill with which the milling operations are performed. A good wheat grist will produce a poor or unsatisfactory flour if the milling plant or the operation of it is at fault, but a poor wheat grist will yield poor flour even on the most modern and well-designed mill operated to the best advantage. The formulation of a good wheat blend is, therefore, the first necessary step in the production of good flour. The three criteria that a miller has to consider when compounding his wheat blend, apart from factors such as bushel weight and moisture content which influence milling behaviour, are protein content, protein quality and diastatic activity. The first two of these three factors jointly determine the physical properties of a dough made from the flour and hence the manner in which it responds to the manual and mechanical treatment it receives in the bakery and its ability to develop in the oven, while the third factor is an index of the power of the flour to produce a sugar from its starch.
