New products/New trends

Mass production of RD/RM has been started since 2017, and received favourable reputation. We will be focusing on the R&D of new components, breed improvement for mass production, and taste improvement on Rebaudioside series.


Lately, Reb-D has become a new component which is studied and applied into products, It has an unparalleled sweet taste comparing to traditional steviosides, and its aqueous solution tastes almost exactly the same as sugar solution. Because the content of Reb-d is quite lower in dry leaves, currently it tends to be used in high-end products. With the R&D of new stevia seedling, the future of Reb-d is very promising.


Although the sweetness of Reb-B is not high, It does generate a fine taste in different stevia-involved formulations; while mixing it with other stevia compounds, it inhibits the possible bitter taste and brings fascinating smell.


As a newly discovered steviol glycoside which is not included in JECFA Reb-M showed its superior taste compare to Reb-d in recent developing and testings, and it gains the favor of several leading brands of food and beverages.
