Experimental: Acid stable emulsion with solid droplets
Acid stable emulsion with solid droplets will be consumed by participants in one study visit along with 1500 mg of crushed and dissolved acetaminophen.
|
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)
