New Research found that the Sweet, Stevia Plant Molecules remain unchanged throughout the Stages of Processing

A new research study conducted at the University of Bonn in Germany found that the sweet, stevia plant molecules remain unchanged throughout the stages of processing. The study supports stevia's naturality and found all nine of the steviol glycoside molecules required by the specifications set by the Joint Expert Committee on Food Additives (JECFA), a committee jointly administered by the Food and Agriculture Organization (FAO) of the United Nations and the World Health Organization (WHO), were present and unchanged in the dried stevia leaf, through the commercial extraction and purification process and in the final stevia leaf extract product.

This research looked at three separate batches of stevia leaf that went through commercial production to final product, the 95 percent purity stevia leaf extract. The study samples were provided by PureCircle and each of the three, commercial batches included the dried stevia leaf, the first water extract and the final product from each of the three corresponding leaf samples. The research found that the stevia leaf extract end products were of 95 percent purity, which is required by JECFA. This is the first time a study has examined steviol glycosides from multiple commercial stevia leaf samples through different stages in the extraction and purification process, starting with the leaf and ending with the stevia sweetener end product.
