Hectoliter weight determination is performed to determine the flour yields of wheat, barley and similar grains. This method of analysis is also known as 1000 grain weight. Hectoliter weight is expressed in kilograms of 100 liters of wheat. Wheat quality is demonstrated with this simple method.

Hectoliter weight is one of the evaluations based on wheat purchases and classification. The higher the hectoliter weight of wheat, the higher the amount of dry matter and flour yield. Hectoliter weight varies according to the type of wheat, sowing season, growing period and ecological conditions.

There are other factors affecting the hectolitre weight of wheat. For example, grain size and shape of wheat, whether the crust is thin or thick, whether the grain is flat or deep, whether the crust is bright or not, affects the hectolitre weight.

Mainly, long-grain wheats are shorter, small-grain wheats are larger, big-shelled wheats are thin-crusted, snow-deep pit wheats are flat and soft wheats are harder than hard ones.

In addition, the amount of impurities found among the wheat grains is also effective on the hectoliter weights. In addition, damaged and broken germinated grain from harmful insects also reduce the weight of hectoliters.

Analyzes to determine the weight of hectoliters in cereals are carried out within the scope of physical analyzes in authorized laboratories. During these analyzes, the standards published by local and foreign organizations are complied with. At the same time, generally accepted test methods and test criteria are followed and reliable and objective results are obtained.

The standards considered during these analyzes are:

• TS EN ISO 7971-1 Cereals - Determination of bulk density (mass / hectoliter) - Part 1: Reference method

• TS EN ISO 520: 2010 Grain and legumes - Determination of 1000 grain weight
• TS 2974 Wheat
