Carriers of MD showed
significant protective effects against the loss of flavonoids and total
phenolics in the course of the spray drying. The higher total phenolic
content in flour with carrier of MD might be due to interference of
maltodextrin with the phenolic compounds during analysis
(Ahmed, Akter, Lee, et al., 2010). In addition, it was possible that the
higher degree of agglomeration for flour without carrier would
lower the exposure of flour to oxygen and therefore, protecting the
phenolic compounds from destruction (Quek et al., 2007).
