Which Mogroside V grade should I specify — MV20, MV30, MV50 or MV70?
Choose a Mogroside V grade by cost-in-use and flavour, not by price per kilogram. MV20–MV30 suit dry mixes and cost-sensitive blends, MV40–MV50 suit beverages and dairy, and MV60–MV70 suit applications where the inclusion rate must be minimised or the label kept short.
TL;DR — the short answer
- MV20–MV30: highest inclusion rate, lowest price per kg, good for dry mixes.
- MV40–MV50: the general-purpose range for beverages, juice and dairy.
- MV60–MV70: lowest inclusion rate, cleanest taste, smallest label footprint.
- Sweetness equivalence does not scale linearly with Mogroside V content.
- Validate one grade at bench scale before committing to a volume buy.
Evidence and regulatory basis
The position above rests on the following public records. Each is linked in full at the end of this article so you can verify it yourself.
- Mogroside V is measured by HPLC; total mogrosides measured by UV is typically higher on the same sample, and some specifications quote one rather than the other.
- Sweetness equivalence ranges from roughly 150× sucrose at MV20 to roughly 320× at MV70, and the relationship compresses as the grade rises.
- Monk fruit extract is heat-stable through pasteurisation, UHT and baking, which is a practical advantage over some high-intensity sweeteners.
- JECFA and Codex publish identity and purity specifications referenced by many regulators.
- Free evaluation samples of 20–200 g are typically dispatched within 24–48 hours, enough for bench trials at three inclusion rates.
What the number on the drum actually means
The MV number is the Mogroside V content determined by HPLC. Mogroside V is the single sweetest of the mogrosides in the fruit, but it is not the only one — total mogrosides determined by UV is typically higher than the Mogroside V figure on the same sample. A certificate that quotes only one of the two is not giving you the full picture.
That distinction explains why sweetness equivalence does not scale linearly with the MV number. MV70 is not simply 3.5 times sweeter than MV20; the relationship compresses as the grade rises, which is why the cost arithmetic favours the middle of the range more often than buyers expect.
Ask for both numbers on the certificate. If a supplier will only give one, ask which method was used, because the answer determines whether you are comparing like with like across two quotes.
Flavour changes with grade
Lower grades carry more of the fruit’s non-mogroside material, which reads as a slightly rounder, occasionally more fruity profile. Higher grades taste cleaner and more sucrose-like in the front, with less of the lingering sweetness some formulators dislike.
This is why the highest grade is not automatically the right choice. In a strongly flavoured system — a spiced bakery product or a chocolate — the flavour contribution of a lower grade is masked entirely, and paying for MV70 buys nothing.
The reverse also happens. In a lightly flavoured sparkling water, the fruit note of a low grade is audible, and buyers who chose MV20 on price end up adding a masking flavour that costs more than the grade upgrade would have.
Matching grade to application
Ready-to-drink beverages are the most grade-sensitive category, because clarity and aftertaste are both visible in the finished product. MV40 to MV60 is where most beverage work lands. Dry mixes and powdered drinks tolerate higher inclusion rates and are where MV20 to MV30 earns its keep.
Dairy and plant-based drinks sit in the middle, with the additional constraint that the sweetness has to survive pasteurisation without developing an off-note. Monk fruit extract is heat-stable across the normal pasteurisation and UHT window, which is a genuine advantage over some high-intensity sweeteners.
Tabletop and sachet applications push toward the highest grades, because the serving size is fixed and the powder volume per serving has to be minimised for the product to feel right to the consumer.
The blending option
A co-blend removes the dosage problem entirely. Instead of weighing microgram-scale quantities of a high-intensity extract and a bulking agent separately, the production team weighs one ingredient with a fixed ratio, and every batch tastes the same.
Erythritol, allulose and tagatose are the usual partners, and each brings something different: erythritol the cleanest cooling taste and the lowest cost, allulose the browning and freezing-point depression, tagatose the closest approach to sucrose bulk.
The engineering benefit is consistency. A ratio fixed at blending cannot drift the way two separate weighings can, and for a plant running a high-throughput line that is worth more than the small difference in ingredient cost.
How to validate a grade
Run a bench trial at three inclusion rates around the target, taste at room temperature and at the serving temperature, and re-taste after a week of accelerated storage. Sweetness perception shifts with temperature and with storage, and a grade that is correct on day one can drift.
Order the sample at the same time as you order the certificate of analysis for the batch it came from. That way the trial result and the specification refer to the same material — which is not guaranteed if you buy the sample from stock.
Finally, run the trial in the real matrix, not in water. Sweetness perception in a fat-containing or high-acid system is not the same as in water, and a dosage validated in water is frequently wrong in the finished product.
Grade selection by application
| Application | Recommended grade | Why |
|---|---|---|
| Powdered drink mixes | MV20 – MV30 | Higher inclusion is invisible in a dry mix |
| Ready-to-drink tea and juice | MV40 – MV50 | Clarity and clean finish matter |
| Sparkling water | MV50 – MV60 | Low inclusion keeps the profile crisp |
| Dairy and plant-based drinks | MV40 – MV60 | Heat-stable through pasteurisation |
| Bakery | MV30 – MV50 | Flavour contribution is masked by the matrix |
| Tabletop and sachets | MV50 – MV70 | Minimum powder per serving |
| Premium clean-label launches | MV60 – MV70 | Shortest label, cleanest taste |
Specification fields to compare across grades
| Parameter | MV20 | MV50 | MV70 |
|---|---|---|---|
| Mogroside V (HPLC) | ≥ 20.0 % | ≥ 50.0 % | ≥ 70.0 % |
| Total mogrosides (UV) | ≥ 40.0 % | ≥ 75.0 % | ≥ 90.0 % |
| Sweetness vs sucrose | 150 – 190× | 200 – 250× | 250 – 320× |
| Appearance | Light yellow powder | Light yellow to off-white | Off-white fine powder |
| Typical inclusion in a beverage | Highest | Moderate | Lowest |
Case: choosing a grade for a sparkling water line
A sparkling water brand tested MV20, MV50 and MV60 at three inclusion rates each. In water at room temperature all three were acceptable, and MV20 was the cheapest by a wide margin.
The ranking changed at serving temperature. Chilled, the fruit note of MV20 became audible at the inclusion rate required, while MV50 and MV60 stayed clean. The brand also found that MV20 needed a higher inclusion rate, which pushed the powder contribution far enough to affect the mouthfeel.
After a week of accelerated storage the difference widened further: the MV20 samples developed a slight haze, which the higher grades did not.
The brand specified MV60. The powder cost per litre was higher than MV20, but the formulation needed no masking flavour, the label was shorter, and the product held up through storage — which is what determined the decision.
| Grade | In water at 20 °C | Chilled at 4 °C | After accelerated storage |
|---|---|---|---|
| MV20 | Acceptable | Fruit note audible | Slight haze |
| MV50 | Clean | Clean | Stable |
| MV60 | Clean | Cleanest | Stable |
How the number on the certificate is actually produced
The single most common source of a bad purchase decision in this category is two suppliers quoting the same figure for Mogroside V from two different analytical methods. The number is only meaningful together with the method that produced it. Ask for both, every time, before you compare prices.
The reference method for Mogroside V in monk fruit extract is reversed-phase HPLC with UV detection against a certified Mogroside V external standard. In practical terms that means the sample is dissolved, filtered, injected against a certified external standard, and quantitated on the peak area. Results are reported on the as-is basis unless the certificate states otherwise, which matters because a drum that has picked up moisture during a humid sea crossing will assay lower on the as-is basis while the chemistry is unchanged.
A competent supplier will also state the loss on drying, the heavy metals result, the microbiological counts and the residual solvent result on the same certificate. If any of those four is missing, you are not looking at a full certificate of analysis — you are looking at an assay report, and the difference matters the first time a customer auditor asks you for the full document.
Specification matrix: what each grade actually buys you
Grade names in this category are marketing shorthand, not a standard. One supplier’s ‘premium’ can be another’s mid-grade. What is comparable across suppliers is the analytical figure and the inclusion rate it lets you use. The matrix below maps the grades we run to the two numbers that decide your cost in use.
| Grade | Mogroside V (HPLC) | Sweetness vs sucrose | Starting inclusion rate | Flavour load | Best application |
|---|---|---|---|---|---|
| MV20 | 20 % | 150–190 × | 0.15–0.25 % | High | Bakery, sauces, dark beverages; any matrix that masks it |
| MV25 | 25 % | 170–210 × | 0.12–0.20 % | High | Cost-sensitive beverages and dairy |
| MV30 | 30 % | 190–230 × | 0.10–0.18 % | Moderate | General-purpose beverage, yoghurt, plant-based drinks |
| MV40 | 40 % | 220–260 × | 0.08–0.14 % | Moderate | Mid-tier beverages where clarity matters |
| MV50 | 50 % | 200–250 × | 0.07–0.12 % | Low | Clear beverages, delicate flavour systems |
| MV60 | 60 % | 230–280 × | 0.05–0.09 % | Low | Functional shots, lightly flavoured water |
| MV70 | 70 % | 250–320 × | 0.04–0.07 % | Very low | Premium water, clean-label positioning, taste-critical SKUs |
Read the last two columns together. A grade that costs more per kilogram but halves your inclusion rate can be cheaper per finished tonne, and it usually tastes cleaner because you are adding less of the non-sweet fraction. Run that arithmetic on your own formulation before you decide — the answer genuinely changes with the matrix.
Reading the certificate of analysis line by line
Below is the line structure we issue on monk fruit extract. Use it as a checklist when you compare two quotes: if one supplier’s document has fewer lines, the missing lines are usually the ones that would have shown a problem.
| Certificate line | Method | Typical result | Why it matters to you |
|---|---|---|---|
| Assay — Mogroside V | HPLC-UV, external standard | 20–70 % by grade | Defines the grade and the inclusion rate you can use |
| Assay — total mogrosides | UV spectrophotometry | 5–15 points above Mogroside V | The gap indicates how much non-V glycoside material you are adding |
| Loss on drying | 105 °C / 2 h or Karl Fischer | ≤ 5.0 % | Caking risk; also depresses the as-is assay |
| Heavy metals (Pb, As, Cd, Hg) | ICP-MS | Pb ≤ 1 mg/kg, As ≤ 1 mg/kg | Standard import requirement in most destinations |
| Microbiology | Plate count / PCR | TPC ≤ 1,000 cfu/g; Salmonella absent in 25 g | Mandatory for beverage and dairy applications |
| Residual solvent (ethanol) | GC headspace | ≤ 50 mg/kg | Confirms the extraction route was controlled |
| Appearance and colour | Visual / spectrophotometric | Pale yellow to off-white powder | Not always printed, but decisive for clear beverages at MV20–MV30 |
Two lines deserve special attention. The first is the batch number: a sample that ships from a different batch than the certificate is not evidence of anything. The second is the retest date rather than a hard expiry — a retest date means the material can be released again after a passing re-assay, which is standard practice for stable powders and worth real money on slow-moving inventory.
Formulation notes by application
The same monk fruit extract behaves differently in different matrices. The starting points below are where our technical team opens a bench trial; treat them as a starting dose to optimise, not a finished formulation.
| Application | Recommended grade | Starting inclusion rate | Blending partner | Why that grade |
|---|---|---|---|---|
| Clear still water | MV60 – MV70 | 0.04–0.08 % | None, or a trace of allulose | Nothing to mask the flavour load; taste is the whole product |
| Flavoured sparkling beverage | MV40 – MV50 | 0.07–0.12 % | Erythritol or allulose for body | Fruit flavour carries the load; cost stays sane |
| Dairy and yoghurt | MV30 – MV40 | 0.10–0.16 % | Allulose | Acidity and fat mask the difference; value wins |
| Plant-based drinks | MV40 – MV50 | 0.08–0.13 % | Allulose | Off-notes from the base need a cleaner extract |
| Bakery | MV20 – MV30 | 0.15–0.25 % | Erythritol bulking system | Maillard and spice mask everything; lowest cost in use |
| Table-top sachets | MV30 – MV50 | 0.20–0.40 % of blend | Erythritol | Balance of taste and cost at high visibility on the palate |
| Sauces and dressings | MV20 – MV30 | 0.10–0.20 % | None | Acid, salt and spice mask the load completely |
Validate in the real matrix at the real serving temperature, and re-taste after accelerated storage. Sweetness perception shifts with acidity, fat, alcohol and temperature, and a dose that is correct in water is frequently 10–30 % off in the finished product.
Stability, storage and shelf life
Monk fruit extract is a stable powder when it is kept dry and sealed, and most of the shelf-life problems reported in this category are moisture and aroma problems rather than degradation of the sweetening compound itself. The data below is the basis for the shelf-life statement on our documentation.
| Condition | Duration | Observed result |
|---|---|---|
| Sealed, ≤ 25 °C, < 60 % RH | 24 months from manufacture | All grades; assay, moisture and appearance within specification |
| Opened drum, resealed after use | Use within 6 months | Surface moisture pickup; caking possible at higher humidity |
| Accelerated 40 °C / 75 % RH | 6 months | No meaningful loss of Mogroside V at any grade |
| In aqueous solution, pH 3.0–7.0 | 12 weeks at ambient | Stable; no grade-dependent difference observed |
| Through UHT and pasteurisation | Process duration | No measurable degradation; suitable for hot fill at every grade |
| Through baking (180–200 °C) | Process duration | No sweetness loss; the advantage over several other high-intensity sweeteners |
Store sealed, below 25 °C, away from direct sunlight and away from strongly aromatic material. Once opened, reseal immediately or transfer to a smaller container — the headspace in a half-empty drum is where caking starts. Material that has caked can usually be milled back to a free-flowing powder and re-assayed, but the assay should be re-run before it goes into a blend.
Six mistakes that cost buyers money in this category
These come up in almost every first conversation with a new account. None of them is expensive to avoid, and all of them are expensive to discover after the container has shipped.
- Always buying the highest grade. MV70 buys a lower inclusion rate and a cleaner taste. In a strongly flavoured matrix you cannot taste the difference and the premium is wasted.
- Always buying the lowest grade. In a clear, lightly flavoured water the flavour load at MV20 is the product’s dominant characteristic, and no amount of formulation work will remove it.
- Validating at one inclusion rate. Sweetness curves are not linear. Trial at least three rates and plot the curve; the grade that wins at one rate does not always win at another.
- Tasting at room temperature only. A beverage is consumed cold. Perceived sweetness shifts with temperature and a dose validated at 20 °C is frequently wrong at 5 °C.
- Trailing in water. Fat, acidity, alcohol and temperature all shift perceived sweetness. Expect a 10–30 % correction between water and the real matrix.
- Fixing the grade before fixing the bulking partner. Most ‘monk fruit taste problems’ are actually bulking-agent problems. Solve the partner first; the grade decision usually gets easier.
Glossary of terms used in this article
- Mogroside V
- The principal sweetening triterpene glycoside in monk fruit and the figure that defines the grade. Higher Mogroside V means less non-sweet material per unit of sweetness.
- Total mogrosides
- The whole glycoside family measured by UV spectrophotometry. The gap between this and Mogroside V indicates how much non-V material you are adding.
- Flavour load
- The amount of non-sweet material that comes with the sweetness at a given dose. Lower grades carry more of it, which is why they suit strongly flavoured matrices.
- Inclusion rate
- The percentage of sweetener added to a finished formulation, by weight. Falls as the grade rises.
- Sweetness equivalence
- The multiple of sucrose sweetness a sweetener delivers at equal perceived intensity. For monk fruit extract this ranges from about 150 × at MV20 to about 320 × at MV70.
- Sweetness curve
- How perceived intensity changes with concentration. Not linear for most high-intensity sweeteners, and the reason single-rate trials mislead.
- Bulking agent
- A material such as erythritol or allulose used to replace the volume and mouthfeel that sucrose provided, while a high-intensity sweetener supplies the sweetness.
- Off-note
- Any perceptible flavour that is not sweetness — bitterness, liquorice, metallic or aftertaste. Usually the limiting factor at low grades in delicate matrices.
- Caking
- The formation of hard lumps in a powder through moisture pickup. Cosmetic in most cases; re-milling and re-assaying is normally sufficient.
What to ask a supplier before you commit volume
- Ask for both Mogroside V by HPLC and total mogrosides by UV on the certificate.
- Validate at three inclusion rates, not one.
- Taste at room temperature and at the serving temperature.
- Re-taste after accelerated storage before locking the dosage.
- Run the trial in the real matrix, not in water.
- Order the sample from the same batch as the certificate of analysis.

Frequently asked questions
Should I always buy the highest grade?
No. MV70 buys a lower inclusion rate and a cleaner taste, which matters in a lightly flavoured beverage. In a strongly flavoured matrix the difference is masked, and MV20–MV30 is better value.
What is the difference between Mogroside V and total mogrosides?
Mogroside V is one specific compound measured by HPLC; total mogrosides measures the whole glycoside family, usually by UV. Total mogrosides is normally higher than the Mogroside V figure on the same sample.
Is monk fruit extract heat-stable?
Yes, through the temperature range used for pasteurisation, UHT and baking. That is one of its practical advantages over some other high-intensity sweeteners.
Can I blend grades?
Yes. Many formulators blend a lower grade for body with a higher grade for the sweetness curve. A purpose-made co-blend removes the weighing step by fixing the ratio at blending.
How much sample do I need for a trial?
Free evaluation samples of 20–200 g are dispatched within 24–48 hours. That is enough for bench trials at three inclusion rates with room to repeat.
Does the grade affect solubility?
All grades are cold-soluble at the inclusion rates normally used. Solubility problems in practice almost always come from a bulking partner, not from the extract.
Why does my dosage validated in water fail in the finished product?
Because sweetness perception changes with the matrix. Fat content, acidity and temperature all shift the perceived sweetness, so always validate in the real formulation.
Can I blend two grades?
Yes, and many formulators do — a lower grade for body with a higher grade for the sweetness curve. Our custom sweetener formulation service fixes the ratio at blending so that the weighing step disappears from your plant.
Which grade should I start with if I have never used monk fruit?
MV30 for a flavoured application and MV50 for a clear or delicate one. Those two cover most first projects, and the trial will tell you immediately whether to move up or down.
Does a higher grade dissolve faster?
Not meaningfully. All grades are cold-soluble at the inclusion rates normally used. Dissolution problems in practice almost always come from a bulking partner, not from the extract.
Does the grade affect the colour of my finished beverage?
It can at the low end. MV20–MV30 in a clear beverage at a high inclusion rate can add visible colour. If clarity is a specification, start at MV50.
Is there a taste difference between grades from the same supplier?
Yes, and it is the main reason to trial two grades side by side rather than choosing on paper. The difference is largest in water and smallest in a strongly flavoured, acidic or fatty matrix.
How do I compare grades from two different suppliers?
Insist on the same analyte, the same method and the same basis from both, then trial at three inclusion rates in your real matrix. Everything else is paper comparison and paper comparison is where most bad decisions are made.
Do you supply a co-blend so I do not have to weigh two powders?
Yes. Erythritol + monk fruit, allulose + monk fruit, tagatose + monk fruit and stevia Reb-M + monk fruit co-blends are all supplied with the ratio matched to your target sweetness curve, at a 25 kg minimum.
What sample size do I need to trial two grades?
20–200 g is enough for bench trials at three inclusion rates with room to repeat. Samples are free and dispatch within 24–48 hours from the certified lot.
Does the grade change the regulatory position?
Generally no — approval attaches to the material and its specification, not to the grade. But confirm the specification you will import matches the one your market has assessed, particularly on solvent residue and pesticides.
