Rising CO2 levels alter wheat protein composition, study finds
A study led by the Leibniz Institute for Food Systems Biology at the Technical University of Munich reveals that rising atmospheric carbon dioxide (CO2) levels are altering the protein composition of wheat. Researchers observed that as CO2 levels rose from 340 ppm in 1980 to 425 ppm in 2024, and are projected to reach 600 ppm by 2050, the chemical makeup of wheat grains undergoes significant changes.
Findings published in the journal Food Chemistry indicate that higher CO2 concentrations increase the levels of amylase/trypsin-inhibitors (ATIs), which may have adverse effects on human health. Conversely, there is a recorded decrease in gluten proteins, puroindolines, and certain peptides associated with celiac disease. The reduction in gluten proteins is particularly concerning for the food industry, as it may diminish the elasticity and baking quality of dough used for bread and other staples.
The research, which tested ten varieties of winter wheat under varying CO2 conditions, noted that the extent of these protein alterations varies depending on the specific wheat cultivar.
