Release characteristics of flavor from spray-dried powder in boiling water and during rice cooking.

The release characteristics of flavor in boiling water and the flavor retention in the rice after cooking were investigated by using spray dried powder in encapsulated in or emulsified with d-limonene or ethyl n-hexanoate in cyclodextrin and maltodextrin, or in gum arabic and maltodextrin. The behavior of flavor release into the boiling water was well simulated by Avrami's equation. The retention of d-limonene and ethyl n-hexanoate in cooked rice was correlated in each case with the flavor amount of spray-dried powder added.
