Thermal and Morphological Properties of Waste Product and Leaf Powder of Stevia Rebaudiana Bertoni
Journal Title: International Journal of Agriculture Innovations and Research - Year 2018, Vol 7, Issue 2
Abstract
Stevia rebaudiana Bertoni, belonging to the Compositae family, is a sweet herb contains diterpene glycos- -ides, namely, stevioside, rebaudiosides A–F, steviolbioside, and dulcoside A, which are responsible for the typical sweet taste. Waste product and dried leaf of stevia rebaudiana were analyzed heavy metals, scanning electron microscopy, Thermal properties (DSC) and FT-IR spectrum analysis. (Mercury) Hg, (Selenium) Se, (Cadmium) Cd and (Lead) Pb were determined in waste stevia (0.07μg /g, 0.8μg / g, 0.11μg /g and 0.19μg /g) respectively. (SEM) were scanned for both samples and clear difference was observed in samples. Thermal characteristics (DSC) was investigated and results showed slight various between waste and leaf powder of stevia, after that FTIR was studied and appeared different chemical groups in waste and leaf sample of stevia rebaudiana respectively.
