  This work describes the chemical characterization of Aloe vera leaves after dissecting the whole leaf into filets and skin, and characterizes the mucilaginous gel extracted from the filets. Gel was extracted by hand-fileting the leaves and pressing the resulting filet. The mean gel yield was 86.3% from the whole filet and the volume of freeze-dried gel was 0.91% that of fresh gel. The volume of the pressed fresh residue (cake) of the filet after extracting the gel was 15.1% that of the whole filet. The fresh gel had a moisture content of 97.8%, a pH of 5.24 and 0.07% acidity expressed as malic acid. Water content analysis of the freeze-dried gel and dehydrated cake revealed moisture values of 2.3% in the gel and 6.9% in the cake. The ash content was 17.20% in the gel and 13.15% in the cake. The total dietary fiber determined in the cake (71.5%) was greater than that of freeze-dried ge.. View More»
