Vitamin A composition
The present invention relates to a composition comprising triglycerides, surfactant, self-assembled structures and vitamin A or provitamin A. Further aspects of the invention are a food product, the use of a composition comprising triglycerides, surfactant and self-assembled structures to stabilize vitamin A or provitamin A and a process for preparing a stabilized vitamin A or provitamin A composition.
1. A process for preparing a stabilized vitamin A or provitamin A composition, the process comprising:
providing triglycerides, lecithin, and at least one liquid compound selected from the group consisting of vitamin A and provitamin A; and
mixing the triglycerides, the lecithin and the at least one compound to form the stabilized vitamin A or provitamin A composition,
wherein the stabilized vitamin A or provitamin A composition consists of the triglycerides, the lecithin, the at least one compound, and water;
the triglycerides are at least 50 wt. % of the total weight of the stabilized vitamin A or provitamin A composition;
the lecithin is 0.1-30 wt. % based on the amount of the triglycerides; and
the stabilized vitamin A or provitamin A composition has a water content between 0.001 wt % and 4 wt. % of the total weight of the stabilized vitamin A or provitamin A composition.
2. The process according to claim 1 , wherein at least a portion of the lecithin forms self-assembled structures having a reversed micellar cubic structure.
3. The process according to claim 1 , wherein at least part of the at least one compound is dissolved in the triglycerides.
4. The process according to claim 1 , wherein the process further comprises adding and mixing an antioxidant to the stabilized vitamin A or provitamin A composition.
5. The process according to claim 4 , wherein the antioxidant is selected from the group consisting of rosemary extract, green tea extract, a butylated phenol and combinations thereof.
6. The process according to claim 1 , wherein the stabilized vitamin A or provitamin A composition has a water activity greater than 0.3.
7. The process according to claim 1 , wherein the surfactant is 0.5-6 wt. % of the stabilized vitamin A or provitamin A composition.
8. The process according to claim 1 , wherein the at least one compound is at least 0.1 wt. % of the stabilized vitamin A or provitamin A composition.
9. The process according to claim 2 , wherein the triglycerides form an oil phase of the stabilized vitamin A or provitamin A composition, and the self-assembled structures are in the oil phase.
10. The process according to claim 2 , wherein the self-assembled structures are at least 0.05 wt. % of the stabilized vitamin A or provitamin A composition.
11. The process according to claim 1 , wherein the stabilized vitamin A or provitamin A composition is an emulsion.
