Is Monk Fruit Sweetener Safe?
The FDA has not objected to it. It says it has evaluated GRAS notices for extracts of Siraitia grosvenorii Swingle fruit, also known as Luo Han Guo or monk fruit, and has not questioned the notifiers’ conclusions that the extracts are generally recognized as safe under the intended conditions of use identified in those notices.
The FDA says monk fruit is a plant native to Southern China, that its fruit extract contains varying levels of mogrosides, the constituents primarily responsible for its sweetness, and that depending on the mogroside content the extract is reported to be 100 to 250 times sweeter than sugar. The extracts are intended for use as general-purpose sweeteners and as tabletop sweeteners.
The FDA has not specified an acceptable daily intake for monk fruit, and says an ADI may not be necessary for several reasons, including evidence of an ingredient’s safety at levels well above the amounts needed to sweeten food. More broadly, it says sweeteners like these contribute only a few or no calories to the diet and generally will not raise blood sugar levels.
