Protein Content — Soft Wheat

Triticum aestivum L.

The protein content in Triticum aestivum L. grain determines its technological properties, market value, and grade. This indicator varies from 8% to 25%, depending on variety genetics, agronomic practices, and weather conditions during the grain-filling period.

In the reference 1 028 varieties crop Bread wheat, where this is mentioned in the description.

The range of protein content directly influences the classification of soft wheat: for Class 1, a minimum level of 14.5% is required, while for Class 3, the requirement is at least 12.0% on a dry matter basis. A level below 10% is considered low, which leads to insufficient accumulation of gluten proteins and a deterioration of baking properties, such as elasticity and the dough's ability to retain its shape.

Protein accumulation is the result of genotype and environmental interaction, with warm and dry weather during the growing season contributing to more intensive synthesis of protein compounds. Protein serves as the structural basis of gluten, which provides dough elasticity; however, the total protein quantity does not always guarantee high quality, as the amino acid composition and the state of the protein complex also play a decisive role.
