Changes of volatiles' attribute in durian pulp during freeze- and spray-drying process.

Changes of volatile profile from durian (Durio zibethinus) pulp during freeze-drying and spray-drying process were studied using headspace SPME coupled to fast GC–TOFMS. Results showed that 4 esters diminished in the volatiles' composition of freeze-dried pulp and spray drying caused losses of...
