Abstract
The invention relates to a process for producing dry powders of one or more carotenoids by a) dispersing one or more carotenoids in an aqueous molecular or colloidal solution of a mixture of lactose and a protective colloid and b) converting the dispersion which has formed into a dry powder by removing the water and, where appropriate, additionally used solvents and drying, where appropriate in the presence of a coating material, wherein at least one soybean protein is used as protective colloid in process step a).
Claims21
A method of improving the apparent density and stability of a dry powder of one or more carotenoids which comprises
- a) dispersing the one or more carotenoids in an aqueous molecular or colloidal solution of a mixture comprising effective amounts of lactose and a protective colloid, and optionally containing additional solvents, and
- b) converting the dispersion formed in step a) into a dry powder by removing the water and the additional solvents and drying, optionally in the presence of a coating material,
- wherein at least one soybean protein is used as protective colloid in process step a).
A carotenoid-containing dry powder having an improved apparent density and stability which is obtained by a process comprising
- a) dispersing one or more carotenoids in an aqueous molecular or colloidal solution of a mixture comprising effective amounts of lactose and a protective colloid, and optionally containing additional solvents, and
- b) converting the dispersion formed in step a) into a dry powder by removing the water and the additional solvents and drying, optionally in the presence of a coating material,
- wherein at least one partially degraded soybean protein having a degree of hydrolysis of from 0.1 to 20% is used as the protective colloid in process step a).
A method of improving the apparent density and color stability of a dry powder of one or more carotenoids which comprises
- a) dispersing the one or more carotenoids in an aqueous molecular or colloidal solution of a mixture comprising effective amounts of lactose and a protective colloid, and optionally containing additional solvents, and
- b) converting the dispersion formed in step a) into a dry powder by removing the water and the additional solvents and drying, optionally in the presence of a coating material,
- wherein at least one soybean protein is used as protective colloid in process step a).
