Dry but Not Humid Thermal Processing of Gel Promotes Cytotoxicity on Human Intestinal Cells HT-29.

Aloe vera products, both in food and cosmetics, are becoming increasingly popular due to their claimed beneficial effects, which are mainly attributed to the active compound acemannan.

Food industries typically use as concentrated (100× to 200×) and dried powders in their final products. These powders are obtained by extrusion of inner leaf gel (ILG) or whole leaf (WLP); the juice is filtered through diatomaceous earth and activated carbon before spray drying at temperatures below 70 °C. In another process, inner leaf gel was dried at ~80 °C and mashed to a powder rich in high molecular weight fibres and soluble polysaccharides (ILF).
