In this research, microencapsulated β-carotene powder has been prepared by gelatin using spray drying method. Ability of gelatin for encapsulating of β-carotene was examined. Suitability of β-carotene powder was investigated for using in aqueous media. Prepared emulsion had the average particle size of 2.83 microns caused stability of emulsion. Microencapsulated β-carotene particles had spherical shape with smooth and some dented surfaces. Microencapsulated β-carotene powder had high β-carotene content which is suitable for food industry. Microencapsulation efficiency was 42.7% which was increased up to 50.8% by increment of the gelatin concentration. The cold water solubility of the microencapsulated powder was 73% and the powder was stable in water and did not show phase separation after 14 days.
