CCNY chemists use sugar-based gelators to solidify vegetable oils
Date:12/19/2013

Researchers at The City College of New York have reported the successful transformation of vegetable oils to a semisolid form using low-calorie sugars as a structuring agent. The findings portend the development of alternatives to structured oil products produced using saturated/trans fatty acids, which have been linked to coronary artery disease, obesity and diabetes.

The team, led by City College Professor of Chemistry George John, tested two sugar alcohol-based gelators, mannitol dioctanoate (M8) and sorbitol dioctanoate (S8), as structuring agents for four refined vegetable oils purchased at local grocery stores: canola oil, olive oil, soybean oil and grape seed oil. Both are amphiphiles i.e. molecules that are attracted to water and fats consisting of two octanoic acid chains (C8) appended to a sugar alcohol molecule.

Oils are transformed to semisolid forms known as structured oils. The best known of these are vegetable oil and margarine. Structured oils are also contained in candy and cake frosting.

"We have demonstrated the first sugar-based thickening agents for oil," said Professor John, whose previous investigations into the use of amphiphiles to solidify oil in the presence of water demonstrated their potential use in oil spill cleanups. He added that the two agents meet both Food & Drug Administration and GRAS (Generally Recognized as Safe) safety specifications, so they can be used for food processing.

Both M8 and S8 demonstrated excellent gelation tendencies for all of the oils that were tested, and the gels remained stable for several months. When mixed with the oils, the gelation agents self-assembled into three-dimensional crystalline networks that encapsulated the oils in liquid stage. Optimal gelation was achieved at structuring agent concentrations between three percent and five percent.

However, some differences between the two agents were reported. For example, mannitol gels were opaque in
