Volumes fell 5.1% in the three months to the end of November, the company said, as it was hit by lower output at its biggest factory.
Volumes fell to 579,000 tonnes, from 610,000 tonnes the previous year, said the company, whose products are used by food makers including Nestlé and Unilever.
The declines occurred as the Swiss company started ramping up production again at its Wieze factory in Belgium, which was hit by a salmonella scare last year.
Sales revenue increased by 3.8% to CHF 2.1 billion (€2.1 billion), as the company passed on raw material price increases the company said. In local currencies, revenues increased by 7.2%.
"In markets where Gourmet products were widely available, we continued to win. We are committed to achieve our current three-year mid-term guidance in this final year, based on our broad product portfolio and broad geographic and customer base."

"We had expected coming out of COVID an acceleration," Boone said. "The acceleration is back to a normal trajectory."
Barry Callebaut also said it would target 8% to 10% EBIT growth in local currencies for the period 2023-2026.
