Curcuminoid is an important natural product, but it is water insoluble, and sensitive to light, pH, solvent system, and oxygen.The inclusion process of curcuminoid-β-CD complex was investigated by the orthogonal experiment, and the stability of curcuminoid-β-CD complex was studied under different conditions. The results show that the encapsulation rate is 87.34% under optimized conditions of temperature 50 , time 1.5 h and material ratio 1:30(wcurcuminoid : wβ-CD). The stability of curcuminoid-β-cyclodextrin complex increases compared to curcuminoid. Therefore, the complex formation of curcuminoid with β-CD is an effective method to improve the stability of curcuminoid.
