Abstract: Microencapsulating technology of procyanidins and stability of microencapsulating procyanidins were studied inthis paper. The result showed that microencapsulating rate and efficiency of procyanidins were highest, 73.7% and 82.3%respectively when the rate of protein and β-cyclodextrin(β-CD) in the optium wall was 6:14.Microencapsulating rate andefficiency of procyanidins were higher when temperature and speed of spray drying wind were 190～200℃ and 50ml/minrespectively. It is better for microencapsulating procyanidins when it was stored in lower pH, away from light, high vacumn andlower moisture.

Key words: microencapsulation, procyanidins, stability
