Abstract
The present invention generally relates to the field of membranes. In particular, the present invention relates to a composition comprising bodies surrounded by a membrane. The composition are for example edible compositions. One embodiment of the present invention relates to a composition containing an oily fraction, a hydrophilic fraction, and at least one body, wherein the body comprises a shell comprising several molecular layers of protein and at least one phosphatidic acid surfactant; and a content comprising an internal phase containing a hydrophilic component and/or a hydrophobic component. The composition may be used to protect a food product or to deliver specific properties to a product, for example.

A composition comprising an oily fraction, a hydrophilic fraction, and at least one body, the body comprising
- a shell comprising at least 20 molecular layers of complex molecules, the complex molecules comprising a protein carrying a positive or no net charge at the pH of the composition and at least one lipidic phosphatidic acid, the lipidic phosphatidic acid surfactant content comprises at least 20% w/w of all lipidic surfactants present in the shell, the diameter of the shell being about 100 nm to 1000 μm, and
- a content comprising an internal phase containing at least one of a hydrophilic component and a hydrophobic component.
A method for the preparation of a product comprising the step of using an oily fraction, a hydrophilic fraction, and at least one body, the body comprising a shell comprising at least 20 molecular layers of complex molecules, the complex molecules comprising a protein carrying a positive or no net charge at the pH of the composition and at least one lipidic phosphatidic acid, the lipidic phosphatidic acid surfactant content comprises at least 20% w/w of all lipidic surfactants present in the shell, the diameter of the shell being about 100 nm to 1000 μm, and a content comprising an internal phase containing at least one of a hydrophilic component or a hydrophobic component to make the product.
