Biochemical Activity, Functional Properties and Texture Profiling of Non-bitter and Bitter Type Aloe vera Gel

Aloe vera has long history as a medicinal plant with diverse therapeutic applications and antioxidant properties. Aloe vera contains large number of vitamins, minerals and other biological active compounds. This study was conducted to determine nutrient composition and Functional properties of sweet and bitter type of Aloe vera gel. Gel yield was comparatively more in bitter than non type Aloe vera viz. 521, 422g per kg respectively. The result of the phytochemical screening showed the presence of tannins, saponins, flavonoids and carbohydrate. Ash, fibre, protein and fat content of non bitter and bitter type of Aloe vera gel have slight difference. Bitter type Aloe vera gel shows higher amount of ascorbic acid than non bitter cultivar. Total phenolic content was also higher in bitter type aloe vera gel. Functional group distribution was studied by FTIR spectroscopy. Texture analysis shows that the gel treated with citric acid had maximum firmness.
