Monk fruit vs stevia: what manufacturers should know
Monk fruit extract and stevia are both high-intensity sweeteners from plants. How they compare on taste, grades, cost and labelling — and why many products use both.
Monk fruit extract and stevia are the two best-known plant-based high-intensity sweeteners. Both replace sugar at tiny doses and both are heat-stable, but they come from different plants, taste different and are graded differently.
Where they come from
Stevia sweeteners are steviol glycosides — mainly Reb A and Reb M — purified from the leaves of Stevia rebaudiana. Monk fruit sweeteners are mogrosides — mainly mogroside V — extracted from the fruit of Siraitia grosvenorii, also called luo han guo.
How they are graded
Stevia extracts are sold by the purity of a named glycoside: Reb A 97%, 98% or 99%; Reb M 95%. Monk fruit extracts are sold by their mogroside V content: commonly 25%, 40% or 50%. In both cases the percentage is measured by HPLC and reported on the certificate of analysis.
Taste
Stevia sweetness can linger and, at high doses (especially with Reb A), show bitterness. Monk fruit tends to give a smooth, rounded sweetness, and lower grades can carry a light fruity or caramel note. The two have different time-intensity curves — which is exactly why they work well together.
Cost
Reb A is usually the lowest-cost route to sweetness. Monk fruit extract generally costs more per unit of sweetness, with higher mogroside V grades costing more per kilogram but needing less. Reb M sits at the premium end of stevia. Compare cost per serve at your target sweetness.
Labelling and positioning
Monk fruit suits products positioned around fruit-derived sweetening; stevia is widely recognised by consumers. Check ingredient naming and any claims for your product category with your regulatory adviser — steviol glycosides (INS 960) are a permitted sweetener in the Australia New Zealand Food Standards Code, and for monk fruit you should confirm the position for your category.
Why blend
- A stevia–monk fruit blend often tastes closer to sugar than either alone.
- Blending lets you lower the dose of each, keeping both below the level where off-notes appear.
- Pairing either with a bulking sweetener such as erythritol replaces the volume sugar provides in tabletop and bakery products.

Quick answers
Is monk fruit sweeter than stevia?
They are in a similar high-intensity range. Monk fruit sweetness depends on its mogroside V grade; stevia on the glycoside and purity. Set doses by bench trial.
Can I use monk fruit in baking?
Yes, it is heat-stable. Pair it with a bulking agent to replace the volume and texture of sugar.
