Process for the preparation of a spreadable dispersion
Process for the preparation of a spreadable edible dispersion wherein a mixture of oil and solid structuring agent particles is subjected to stirring and an aqueous phase and/or solid phase is gradually added to the mixture until a dispersion of the desired oil content is obtained, wherein the solid structuring agent particles have a microporous structure of submicron size particles.
1. A process for the preparation of a spreadable edible dispersion comprising subjecting a mixture of oil and solid structuring agent particles, which structuring agent particles comprise mixtures of triglycerides, to stirring and gradually adding an aqueous phase to the mixture until a dispersion is obtained, the dispersion comprising oil and structuring agent as continuous phase, said dispersion comprising an emulsion, wherein the solid structuring agent particles, also described as secondary particles have a microporous structure, and said particles are agglomerates of primary particles of submicron size, said primary particles are platelets having an average thickness of 0.01-0.5 μm.
2. The process according to claim 1 , wherein the solid structuring agent particles are edible lipid.
3. The process according to claim 1 , wherein the lipid is a fat.
4.
