Sweet Tea Leaf Extract

The Sweet Tea Extract, manufactured by Donguan Meiherb Biotech Co., Ltd, is a kind of natural sweetener. The sweet taste from the leaf is attributed to the presence of diterpene glucosides, dominated by the major sweet principle rubusoside. Rubusoside is commonly known as either Sweet Tea Extract or Chinese Blackberry Extract. Rubusoside is a Diterpene Glycoside, composing of steviol and glucoside, lower energy but higher sweet, 300 times than sugar. Rubusoside has a slightly bitter aftertaste, but it is about 115 times sweeter than sucrose at a concentration of 0.025%, making it a good candidate for a natural sweetener.
