Abstract: Microcapsules containing mint oil were prepared with two kinds of starch octenylsuccinate HI-CAP100 and N-LOK. The interfacial properties and emulsifying stabilities of two wall materials have been determined. The results showed that HI-CAP100 not only reduced the interfacial tension but also formed high viscoelastic film by absorbing at oil/water interface. The emulsion formed by HI-CAP100 showed good emulsifying stability. Both the microencapsulation yield and efficiency of encapsulated mint oil with HI-CAP100 as wall material were high to 95%. Furthermore, the retention rate of encapsulated mint oil was 95.3% after stored at 30℃ for 6 months, which indicated that the encapsulated mint oil had perfect storage stability.

Key words: starch octenylsuccinate, interfacial properties, emulsifying stability, mint oil, microencapsulation
