Abstract: The comparative effects of different treatment methods applied in Aloe gel juice extraction, viz. freshly crushing,and steam heating-crushing, freezing-crushing, pectinase-added treatments on extraction yield and quality of Aloe gel juice wereinvestigated. It was indicated that the order of juice yield extracted with different methods was pectinse-added>steam heating>freezing>freshly crushing. Compared to the juice squashed from Aloe gel treated with pectinase, the juice crushed from Aloegel treated with steam heating had low nutrient loss, high retention and low viscosity degradation. It suggested that steam heatingwas adaptable to the extraction of Aloe gel juice.

Key words: Aloe, gel juice, pectinase, extraction
