The short answer
Monk fruit sweetener comes from the fruit of Siraitia grosvenorii, also called luo han guo, a plant native to southern China. Extracts of the fruit are 100 to 250 times sweeter than sugar.[1]
In the US, the FDA has received GRAS notices for monk fruit extract and has not questioned them.[1]
What monk fruit sweetener is
The sweetness comes from natural compounds in the fruit called mogrosides.[1] Because the extract is so intense, a tiny amount does the work of a lot of sugar.
That intensity is also why many tabletop products sold as monk fruit sweetener are blends. Ingredients are listed in order of weight, so if erythritol or sugar comes first, that’s mostly what’s in the bag. Romeé contains no erythritol or other sugar alcohols.
Is monk fruit safe?
GRAS stands for “generally recognized as safe,” a category in US food law.[2] Companies can notify the FDA of their conclusion that an ingredient is GRAS for a specific use. For monk fruit extract, the FDA says it “has not questioned the notifiers’ GRAS conclusions” under the intended conditions of use.[1]
Monk fruit vs other sweeteners
| Sweetener | Sweetness vs table sugar | In Romeé? |
|---|---|---|
| Monk fruit extract | 100 to 250 times | Yes, organic |
| Steviol glycosides (stevia) | 200 to 400 times | No |
| Aspartame | 200 times | No |
| Acesulfame potassium | 200 times | No |
| Sucralose | 600 times | No |
| Agave syrup | A sugar, counted as added sugar | Yes, organic |
Stevia and monk fruit are the two plant-derived options. The FDA describes steviol glycosides as natural constituents of the leaves of Stevia rebaudiana.[1] Between the two, preference mostly comes down to taste.
Why we use monk fruit and agave
We wanted real sweetness without artificial sweeteners and without a sugary can. Monk fruit extract adds sweetness without adding sugar. Organic agave syrup, which counts as added sugar,[3] rounds out the taste. Each can has 4 to 5 g of total sugar, including 4 g of added sugar, which is 8% of the Daily Value.[4]
