What is "opekta"

Opekta, also known as Gies & Co., was a European pectin and spice company that existed between 1928 and 1995. It is notable for its Dutch operation being based in the building at that would later become the Anne Frank House. Opekta started in Germany, and later expanded into the Netherlands in 1933, at which time Otto Frank moved from Germany to Amsterdam to become managing director of the new Dutch operation. Otto Frank was in charge of the manufacturing and distribution of the pectin-based gelling preparations, to be used in jam making. The company continued to trade from the same building whilst Otto Frank, his family (including his youngest daughter Anne Frank) and several other Jews hid from persecution stemming from the Nazi Occupation of the Netherlands during World War II.
