Emulsion Lipid Digestion & Satiety Study - Effect of Physical State and Acid Stability

Summary

The purpose of this study is to compare the changes in blood lipids and feelings of satiety after consumption of acid stable or acid unstable oil-in-water emulsions in which the droplets are in either the liquid or partially solid (i.e. crystalline) states.

Interventions

OTHER

Acid stable emulsion with solid droplets

This will be a 250 mL acid stable beverage emulsion in which the droplets are crystalline. It will have identical similar to the other intervention, i.e. in a set of samples the emulsion lipid droplets are in the liquid state and are either acid stable or unstable and, in the other set of samples they are solid (i.e. crystallized) and are also either acid stable or unstable in the acidic environment of the stomach, and will be introduced at least 7 days apart. The emulsion will contain 20% of the lipid palm stearin with 2.2% of the emulsifier sorbitan monooleate (Tween80)

The emulsion will contain 20% of the lipid palm stearin with 2.5% of the emulsifier sorbitan monostearate (Span60)
