The Minneapolis-based agribusiness will now sell new "native starches" produced from plants such as corn and wheat, as an alternative to more processed starch derivatives used to bulk up food products such as pasta sauce.

"Consumers are scrutinizing labels, looking for products made with plain ingredients they know," a Cargill spokeswoman said in a statement. "This caused many food manufacturers to reconsider the use of modified food starch."

The boost in "label-friendly" ingredients comes amid a broader push for diversification as Cargill and other merchants battle tight margins amid excess grain supplies. It said in September that gains in its starch business helped boost food processing earnings last quarter.

Large food manufacturers have been facing weakening growth in demand for packaged foods as consumers in the United States and Europe increasingly seek to curb consumption of sugar, genetically-engineered (GMO) and artificial ingredients.

A Reuters/Ipsos poll conducted in July showed that nearly half of U.S. respondents said they would consider paying more for foods with "recognizable ingredients."

Also on Tuesday, rival Archer Daniels Midland Co said it will boost output of more high-protein, non-GMO ingredients in Germany due to rising demand.
