Chiffon margarine cottonseed oil. The development of Chiffon margarine was one result. The Chiffon brand and product line has changed hands several times since; the first being in 1985, when Chiffon was sold to Kraft foods. The Kraft U.S. and Canada tablespreads division subsequently became part of Nabisco in 1995; who then sold the brand to ConAgra Foods in 1998. Con-Agra discontinued domestic U.S. and Canadian distribution of Chiffon margarine in 2002. Chiffon margarine can still be purchased in the Caribbean region, however, where it is marketed by Seprod Ltd. under license from Kraft International. The classic Chiffon ads from the D'Arcy
Vegetable oil the margarine does not melt in warm rooms, yet it needs to be completely liquid at 37 °C (98 °F), so that it doesn't leave a "lardy" taste in the mouth. Hardening vegetable oil is done by raising a blend of vegetable oil and a catalyst in near-vacuum to very high temperatures, and introducing hydrogen. This causes the carbon atoms of the oil to break double-bonds with other carbons, each carbon forming a new single-bond with a hydrogen atom. Adding these hydrogen atoms to the oil makes it more solid, raises the smoke point, and makes the oil more stable.
