Sugar-Free Chewing Gum and Mints Sweetener Blend Guide

Define the format before the sweetener

Chewing gum, coated gum, compressed mints, tablet candy and chewable confectionery need different sweetener and flavor-release decisions. Start with gum base or tablet system, piece weight, coating, flavor type, cooling target, texture target and storage condition. A successful compressed mint does not establish performance in a gum base, and an uncoated gum result does not settle a coated product. Keep piece size and the base consistent when comparing sweetener candidates.

Track the early taste and the full eating period

Record aroma burst, cooling, initial sweetness, peak sweetness, bitterness, lingering sweetness and how quickly flavour falls. A sample can taste strong at 20 seconds and still feel empty after two minutes; those times are an illustration, not a standard pass/fail protocol. Choose observation points that capture the intended chewing or dissolution period. Keep preparation, piece weight, serving conditions and the tasting method comparable, use coded samples and include a control. Record aroma and sweetness separately: an instrumental release measurement, perceived aroma and perceived sweetness answer different questions.

Choose the sweetener role carefully

Stevia can support high-intensity sweetness, monk fruit may help round the finish in some systems, and allulose or carrier-supported directions may be considered where the target market and process allow them. Polyols or fibers may still be needed for bulk, hardness or cooling, depending on label goals. High-intensity sweetness alone does not replace the mass, cooling or structure supplied by the bulk system. An erythritol-free direction still needs those functions addressed in the finished piece. Compare identified commercial ingredients and their full blend composition rather than assuming equal powder weights will taste alike.

Verify storage in the intended pack

Gum and mints can lose freshness, aroma and perceived sweetness after warm or humid storage. Compare stored samples with the initial sample and the control, documenting the packaging, temperature, humidity and duration. Check gum texture and coating separately; for pressed mints, include cracking, sticking and moisture pickup as well as flavour. A short accelerated screen helps expose a weak direction. Set acceptance criteria for the actual product, then verify its intended storage and packaging before assigning shelf life. A different texture probe or sample state can change a hardness reading, so keep the method and whether the gum was chewed or unchewed in the record.

Prepare documents and label checks

Tell the supplier the target market early. Sweetener permission, polyol warning rules, ingredient naming, natural flavor position, allergen files, halal files, COA and export documents may affect whether a sample direction can become a commercial quote. Check the actual food category, ingredient specifications and planned claims in that market. A product catalogue or a published gum study does not establish permission for every country, mint or tablet format.

Start with the product and the taste problem

Start with the product format, intended market and what needs to change: a short sweet finish, weak lasting aroma, excess cooling, bitterness or a storage issue. You can contact Hengliyuan before a complete formula or test sheet is ready. Add the known base or tablet system, flavour, current sweetening approach, piece size and ingredient constraints, including whether polyols or erythritol are allowed. For sample planning, share the desired sweetness and cooling, process, packaging and intended storage. Existing sample observations help us discuss an ingredient or blend direction. For procurement, add estimated quantity, document needs and whether samples are required. Hengliyuan can discuss matching ingredient specifications and available supporting documents; confirm the selected material, sample requirements and purchase terms for the actual request.

What the aroma-release study actually measured

Pedrotti et al. (2026) compared five tutti-frutti aroma concentrations in an uncoated model gum. Six trained panellists rated aroma and sweetness at set times while nose-space analysis measured volatile release. The study found an effect of aroma concentration on perceived aroma, but no significant main effect on perceived sweetness. Adding aroma therefore should not be assumed to repair sweetness in another formulation. A separate chewing-simulator experiment measured the release of sorbitol, mannitol, xylitol, maltitol and aspartame. Its early burst and later release pattern was an instrumental result; the study did not test stevia, monk fruit or allulose release. Neither experiment establishes a universal gum or mint formula.

Published aroma scores show why later checks matter

These are selected 30-second and 420-second observations from Table 2 of the same 2026 study, not a reconstructed release curve. Panellists chewed at 60 chews per minute; each sample was evaluated three times by each of the six panellists. The 0–100 scores describe perceived aroma intensity, not aroma mass, sweetness or liking.

What the stevia substitution study supports

Aykut and Kirkin (2025) compared four mint-flavoured gums using sorbitol, with or without partial replacement by xylitol, and either aspartame or stevia. In that system, replacing aspartame with stevia produced no statistically significant change in the reported colour, texture and sensory properties. The sweetener amounts differed; this was not an equal-weight substitution test. Seven trained panellists evaluated sweetness, aroma and freshness after one and five minutes. The samples were individually packed in polyethylene and stored for two weeks at 40°C under cycling humidity conditions. Sensory properties changed during storage, and the polyol choice affected the result. This supports checking both the sweetener and bulk system; it does not establish a universal stevia grade, replacement ratio or commercial shelf life.
