Results evidence the possibility to preserve the physical properties and structure of the SD-powders of Aloe vera if specific process conditions that minimize the effect of the thermal processing are employed. It is important to note that the total phenolic
content and antioxidant capacity of mucilage powders show a remarkable response, scavenging free radicals in the samples processed at lower temperatures, low temperature difference DT (inlet and outlet) and low inlet flow. High expectations of the use of SD in natural biopolymers for possible use in the food industry are
envisaged
