| Abstract: | Objective]The experiment was conducted to investigate emulsion formula of Siraitia grosvenorii seed oil microencapsulation and its properties in order to provide references for manufacturing high-quality Siraitia grosvenorii seed oil microencapsulation and its follow-up development. Method]Based on single factor experiment, emulsion formula of Siraitia grosvenorii seed oil microencapsulation was optimized using response surface methodology, and the property of this product was studied. Result]The results showed that the optimal emulsification condition of seed oil microencapsulation was as follows: using arabic gum as main wall material and beta-cyclodextrin as filler, emulsifier concentration 1.06%, ratio of wall to material 1∶9.8, ratio of core material to wall material 1∶2.71, and solid content of emulsifier 16.69%. Conclusion]The emulsion stability of Siraitia grosvenorii seed oil emulsifier could be as high as 99.4% under the above-mentioned optimal emulsion conditions. The Siraitia grosvenorii seed oil microencapsulation processed by spray drying technology shall be stored at dry environment. |
