Abstract
We describe a solid vegetable oil–water gel structure which is stabilized through the use of low concentrations of monoglycerides, containing no added trans fats or saturated fats. The resulting structure consists of oil droplets encapsulated in self-assembled crystalline monoglyceride multilayers, surrounded by a continuous water phase. Acute ingestion human feeding trials indicated that the serum triglyceride loading was significantly lower after ingestion of the structured gel rather than a simple oil–water mixture, resulting in an attenuated increase in serum insulin. This indicates the effectiveness of encapsulation in modulating blood lipid and insulin response in humans, and suggests a strategy that can be employed for the controlled release of food macronutrients.
