Encapsulation of phytoncide oil using γ-cyclodextin and sodium caseinate for sustained-release |
| 초록 |
The purpose of this study was to prepare sustained-release capsule using γ-cyclodextin(γ-CD)/sodium caseinate(SC) form of the inclusion complexes for phytoncide oil. Phytoncide oil has microbicidal, insecticidal, acaricidal, and deodorizing effect. However, fragrances present compounds that may be lost due to their highly volatility but, by encapsulation, they can be protected during storage and until the final use of the product. The initial γ-cyclodextin : sodium caseinate : xanthan gum ratio was 0.8 : 0.2 : 0.25 this ratio showed encapsulation efficiency of more than 80% and the improvement effect of the sustained-release was better compared with the other complexes. Also, the thermal properties and release behaviors of the microcapsules with γ-CD/SC contents were determined by using the thermogravimetric analyzer(TGA), differential scanning calorimetry(DSC) and UV/vis. spectrophotometer. |
