A report is given on the phase behaviour of various monoglyceride‐water systems relevant in foods. Interactions with cholesterol and bile acid salts as well as small water‐soluble molecules as a third component are described. The cubic phase occurring in systems of monoglycerides of sunflower oil can solubilise bile salts and coexist with bile acid salt micelles, which might result in a reduction in fat absorption in the intestine. Also the observed solubilisation of cholesterol in the cubic phase should be expected to reduce cholesterol uptake when this phase is formed. Evidence is given indicating that monocaproin might be of technical interest in order to solubilise hydrophobic proteins and the interactions between aqueous monocaproin phases and soy‐bean oil and sodium chloride were examined in this context.
