General information

Wheat is a cereal distributed in many food supply operations, in whole grains or as flour.

Wheat can be stored for long periods of time as whole grains, provided the storage is properly conducted.

Fumigation of stocks should be done at least every 3 months; more often if needed.

Milling should be processed only when a distribution date is known, to avoid long storage of flour.

Shelf life of flour is short because the fat content becomes rancid, and a milled product is very sensitive to micro-biological contamination.  Wheat flour can be stored a few weeks or months only, depending on the climatic and storage conditions; check before milling.

Type 55 flour is the most commonly supplied.  It corresponds to an extraction rate of 72% approximately.  The number ‘55’ indicates that the ash residue after burning at high temperature is between 0.5% and 0.6%, which corresponds to the mineral content of the flour.  Higher grades are cruder, such as type 85 or type 125.  These are whole grain types of flour, with a higher extraction rate, higher fat and higher mineral/ash content.

We recommend the type 55 for its’ large availability, its’ wide usage habit and a good life span under normal storage conditions.

The Hagberg test indicates the quality of the starch, and the Zeleny test indicates the quality of the proteins.  If it scores less than 20 for the Zeleny test, the flour cannot make bread dough. Nevertheless, the flour remains fit for human consumption by other means than bread.

Specifications vary with national regulations. Here below, we give our most commonly used specifications:

Refer to HQ when offered specifications which are different from our standard specifications.  It will need to be approved by a food specialist.

Importation of food is always subject to acceptance from the national authorities, based on their national specifications, check these specifications before purchasing.

Impact on the local, national, or regional market availability and prices should be carefully looked at before purchasing large quantities.

The specifications presented below correspond to EC and GOST specifications. There are very similar but EC specification are based on ISO test procedures and GOST specifications are based on ICC test procedures.
