Sweet Tea Extract is commonly known as either Chinese Blackberry Extract or Rubusoside. Our Rubososide is extracted from the leaves of the Chinese Blackberry Bush (Rubus Suavissimus S.Lee). The Extract is 200 times as sweet as cane sugar and contains over 70% Rubusoside. This Extract is processed into a white powder, which is very soluble in water and can be easily  mixed with food without changing the color of the processed food.
