8.4.2 Vacuum-drying. Vacuum-drying is proposed to alleviate some disadvantages of hot-air-drying. The main purpose of vacuum-drying is to allow the removal of moisture under vacuum and hence at a lower temperature condition and oxygen content ( Reis, 2014 ). Vacuum-drying is therefore suitable for heat- and oxygen-sensitive materials.
