Agricultural products retailer Archer-Daniels-Midland Co. said March 15 that it plans to acquire privately held Ziegler Group.

Germany-based Ziegler Group produces citrus oils, extracts, concentrates and compounds for flavor, food and beverage industry customers.

Financial terms of the deal were not disclosed.

The deal is expected to close in the second quarter, subject to regulatory approval.

Earlier in March, Archer-Daniels-Midland completed its $175 million acquisition of Florida Chemical Co. Inc., which specializes in citrus-based flavors and fragrances.
