How Stevia Extract Supports the Global Shift Toward Sugar Reduction

What your market's sugar target actually says

The guideline the World Health Organization published in 2015 recommends reducing free sugars to less than 10% of total energy intake, a strong recommendation, and describes a further reduction to below 5% as conditional. For an adult eating roughly 2,000 kcal a day that is about 50 g and about 25 g. A single can of sugar-sweetened soda can carry up to 40 g of free sugars, so the distance between a typical formulation and the guideline is the reformulation brief.

The same organisation's 2023 guideline on non-sugar sweeteners recommends against using them to control body weight or to reduce the risk of noncommunicable disease. That is a conditional recommendation, it names stevia and stevia derivatives alongside synthetic sweeteners, and it excludes people with pre-existing diabetes. It leaves the JECFA intake assessment that governs permitted use levels untouched. It does remove the option of presenting a sugar-for-stevia swap as a health intervention. Build the commercial case on the sugar number and on taste.

The target that reaches a formulation team is usually a fiscal one. In the United Kingdom, the Soft Drinks Industry Levy has applied since April 2018 and, from 1 April 2025, is charged at £1.94 per 10 litres for drinks with more than 5 g and less than 8 g of total sugar per 100 ml, and £2.59 per 10 litres at 8 g or more. Below 5 g there is no levy. Reformulation between 2015 and 2020 cut the sales-weighted average sugar content of in-scope soft drinks by 46%, and 89% of soft drinks sold in the UK now sit below the 5 g threshold. A 2025 government consultation is considering lowering that threshold, noting that the Nutrient Profiling Model starts scoring total sugar above 4.5 g per 100 g. If you sell into the UK, 5 g per 100 ml is the number your recipe has to clear, and it may get tighter. Huacheng Bio's beverage sweetener application is specified for lasting sweetness with no effect on colour, which is the pair of properties most at risk when a drink is pulled down to a threshold.

What stevia replaces, and what it leaves behind

H2-Via stevia is specified as Rebaudioside A 50% to 99% and Rebaudioside M 95%, assayed by HPLC, and Huacheng Bio describes the material as 200 to 350 times sweeter than sugar. JECFA's specification monograph puts steviol glycosides at 100 to 300 times sweeter than sucrose. At those ratios the sweetness substitution is trivial and the functional substitution is not.

Sucrose was carrying load elsewhere in the recipe. It contributes bulk and crumb structure in baked goods, drives Maillard browning and surface colour, depresses freezing point in frozen desserts, and adds soluble solids that shape mouthfeel and, at high enough levels, help preservation. Remove 100 g of sucrose from a cake and replace the sweetness with roughly 0.3 g of extract and you have removed about 100 g of structure. Partial reductions survive this. Full replacement usually does not, which is why commercial programmes tend to step down 20% to 30% at a time and rebalance the rest of the formula between steps.

That step-down logic has a labelling consequence in the European Union. A food containing an authorised sweetener must carry the statement "with sweetener(s)" alongside the name of the food, and where it contains added sugars as well the statement becomes "with sugar(s) and sweetener(s)". A partial reduction therefore puts both words on the pack, which is a marketing decision before it is an R&D one.

The ceiling on dose: daily intake and category limits

JECFA established an acceptable daily intake of 0 to 4 mg per kg of body weight for steviol glycosides, expressed as steviol, at its sixty-ninth meeting in 2008 and confirmed it again at its 102nd meeting. The ADI applies across the production routes now covered by the specifications, provided the material reaches not less than 95% total steviol glycosides. Huacheng Bio assays H2-Via grades by HPLC, so ask for the total steviol glycosides figure for the grade you are quoted and treat it as the entry point to every intake calculation that follows.

Exposure is where reformulation programmes get caught. At its 102nd meeting JECFA reported estimated dietary exposure of up to 4.8 mg per kg of body weight per day, expressed as steviol equivalents, for high-consuming children in the European Union, above the upper bound of the ADI, while other age groups stayed inside it. JECFA concluded the estimates were not likely to present a health concern for any age group, pointing to how conservative the calculation was. The operational reading is straightforward. Intake is expressed per kilogram of body weight, so estimate it for the heaviest plausible consumer of your product at your own serving size, and do it before a use level is locked.

Then check the category ceiling, which is written in different units. Commission Regulation (EU) No 1131/2011 authorises E 960 steviol glycosides category by category with maximum levels expressed as steviol equivalents: 80 mg/l in energy-reduced flavoured drinks, 200 mg/kg in energy-reduced jam and jelly, 350 mg/kg in confectionery with no added sugar, 3,300 mg/kg in chewing gum, and quantum satis for tabletop sweeteners. A specification sheet quotes glycoside and Rebaudioside A percentages as molecule mass. Convert into steviol equivalents before you compare, or ask the supplier for the conversion for that grade. Outside the EU, take the same question market by market, because permitted categories and conversion rules are not harmonised.

Match the glycoside route to the size of the cut

Grade choice follows the reduction target, and the table below is a starting point for a supplier brief. Sweetness equivalence has to be measured in your own base, at your own pH and process temperature, and until it has been, none of the rows is a finished formulation.

The pattern in that table is consistent: the deeper the cut, the more you pay per unit of sweetness and the more the surrounding recipe has to change. Huacheng Bio applies advanced methods including supercritical fluid extraction and enzyme-assisted extraction to maximise steviol glycoside yield, and that matters to you at the Reb M end, where the route into the molecule determines both cost and the paperwork. Confirm which of the routes was used before you commit to a grade.

Where stevia alone stops working

There is no published threshold for this, but the pattern across categories is hard to miss: once the cut passes about half the original sugar load, most products need a second intervention. Bakery needs bulk and browning back from polyols, resistant dextrins or fibres. Frozen dessert needs freezing point and soluble solids back from the same kind of material. A clear beverage loses body, and the fix is a small amount of fibre or a flavour modulator, or an acceptance that the drink will taste lighter.

The alternative is to buy the system ready-made. Huacheng Bio's H2-Luo range includes a monk fruit blend with stevia and erythritol, supplied at one to four times the sweetness of sugar and designed to match sugar in sweetness and use. A blend at 1 time sugar lets a factory go on dosing by weight as it always did, which removes the conversion step and most of the pilot-plant work. The trade is cost per kilogram and label space: erythritol brings a "with sweetener(s)" statement, and in the EU anything above 10% added polyols has to carry a warning about laxative effects.

What to confirm before you ask for a sample

This list is short enough to send as one email and specific enough to compare two quotations side by side.

• Total steviol glycosides on the dried basis, with the HPLC method and reference standards, plus the individual glycoside profile. A Reb A percentage alone will not tell you whether the material clears 95% total.
• The production route for any Reb M grade, whether water extraction, fermentation, bioconversion or glucosylation. It changes the documentation and any "plant-derived" wording you plan for the pack.
• The steviol equivalent conversion for the quoted grade, so you can check your category maximum level and run your own exposure estimate.
• Residual solvent results with the test method, loss on drying, total ash, lead reported individually, and microbiological results with stated limits, because a conformance tick leaves nothing to audit against.
• Current certificates with issuing body, scope and validity. Huacheng Bio's quality and testing arrangement names NSF-cGMP, ISO9001, ISO22000, BRC, SC(QS), TUV, GRAS, Non-GMO Project, KOSHER and HALAL, so ask for the specific certificate and what product and site it covers.
• The free sample quantity and how it is identified. H2-Via ships a free sample of 10 to 20 g or enough for detection. Ask for the lot identifier to be repeated on the sample and on any commercial lot that follows it.
