The MIC value for freeze-dried and spouted bed powders obtained at 60 °C without carrier was 0.08 mg•mL−1. The MIC values were much higher for powders obtained at higher temperatures and with maltodextrin, ranging between 0.16 mg•mL−1 and 0.31 mg•mL−1 (Table 4). The higher the maltodextrin concentration and inlet drying temperature, the lower the inhibition. In this way, the extract of camu-camu powder produced at 6% MD and from 80 to 100 °C was less effective than the extract produced at 3% MD in the same temperature conditions. Despite loss of inhibitory activity caused by drying, these extracts were more active against S. aureus than ampicillin (MIC 0.26 mg•mL−1).
