| Abstract: |
| Kiwi fruit seed oil microcapsule was prepared by saturated aqueous solution method with kiwi fruit seed oil as core material and β-cyclodextrin as wall material. The effects of wall-oil ratio, embedding temperature and embedding time on the embedding efficiency of kiwi fruit seed oil microcapsule were investigated by single factor experiment and orthogonal experiment. The quality of the microcapsule was evaluated. The results showed that the optimal preparation conditions of kiwi fruit seed oil microcapsule were obtained as follows: wall-oil ratio 4∶ 1, embedding time 90 min, embedding temperature 30 ℃. Under these conditions, the embedding efficiency and the yield of kiwi fruit seed oil microcapsule were 74.52% and 79.33% respectively. The kiwi fruit seed oil microcapsule was light yellow powder, without caking phenomenon and had good fluidity. The peroxide value of kiwi fruit seed oil treated by microencapsulation increased slowly, and the storage stability was significantly improved. |
