Huanfa's Isomalt ST80 — a USP/NF and EP-compliant fine-powder (~80 mesh) sucrose-derived polyol (verified 99.9% GPM+GPS, water 4.8%, reducing sugar 0.06%). High surface area for rapid dissolution, optimal dry blending with HIS, and direct compression performance. Non-cariogenic, low glycemic, bitter-masking. Ideal for tabletop sweeteners, compressed mints, chewing gum coating, and pharmaceutical direct compression. 24-month shelf life. Global shipping from Guangdong, China.
Isomalt ST80 is the fine-powder grade (~80 mesh, ~180 μm) of Huanfa's sucrose-derived disaccharide polyol — the same GPM + GPS chemistry as ST30, milled to a particle size optimized for surface-area-driven applications. With verified purity of 99.9% GPM+GPS (Lot ST2512017, December 2025), water content of 4.8%, and reducing sugar of just 0.06%, ST80 is the grade formulators choose when the process demands intimate mixing with fine powders, rapid dissolution, or the compaction characteristics that only a fine, uniform particle size distribution can deliver.
Where ST30 is a granular workhorse built for melting into hard candy, ST80 is an engineered powder built for blending. Its high specific surface area means it distributes uniformly through multi-component dry mixes — from tabletop sweetener formulations where 1% of a high-intensity sweetener must be homogeneously dispersed through 99% isomalt carrier, to pharmaceutical direct-compression blends where content uniformity depends on particle-level contact between excipient and micronized API. Its rapid dissolution supports instant beverage powders, and its free-flowing fine-particle character makes it the preferred grade for chewing gum dusting and pan coating operations.
ST80 shares ST30's complete quality infrastructure — USP/NF + EP dual-standard compliance, three-stage metal detection, D-grade clean area packaging, and T1 + T2 dual-release authorization — but its particle size unlocks a distinct application portfolio. Together, ST30 and ST80 ensure that whatever your manufacturing process — melting or blending, cooking or compressing — Huanfa has an isomalt grade engineered to match.
Why Source Isomalt ST80 from Huanfa?
1. Verified 99.9% Purity
Lot ST2512017: isomalt content 99.9%, sorbitol + mannitol 0.1%, reducing sugar 0.06%, residue on ignition 0.03%. In tabletop sweeteners where isomalt is 99% of the formulation and the HIS is 1%, the purity of the carrier is the purity of the product.
2. Both Grades, One Supplier
ST30 for hard candy cooking. ST80 for dry blending and compression. One supplier qualification audit, one quality agreement, one commercial relationship — and split-container loads when both grades are needed.
3–7. Same Quality Infrastructure as ST30
Dual pharmacopoeia compliance (USP/NF + EP), three-stage metal detection, D-grade clean area packaging, T1 + T2 dual release, 24-month shelf life, competitive logistics from Guangdong ports.
Optimal dry blend carrier for HIS: When 1% sucralose or 0.5% steviol glycosides must be uniformly distributed through 99% isomalt in a tabletop sweetener, particle size is everything. ST80's fine powder physically interlocks with micronized HIS particles, producing a blend that resists segregation during mixing, transfer, and consumer use — every spoonful delivers the same sweetness.
Direct compression performance: Fine-particle isomalt compacts reliably under moderate compression force, producing tablets with adequate hardness and rapid disintegration — suitable for compressed mints, candy tablets, and pharmaceutical chewable formulations.
Bitter-masking for cleaner HIS taste: Isomalt actively suppresses the bitter, metallic aftertaste of stevia, sucralose, and acesulfame-K. ST80's high surface area maximizes this effect in dry blends — the isomalt and HIS are in intimate contact from the moment the consumer's saliva wets the powder.
Rapid dissolution: Higher surface area = faster wetting and dissolution. In instant beverage powders and effervescent formulations, ST80 dissolves quickly and completely.
Low hygroscopicity: Even in fine-powder form, isomalt's inherent low moisture absorption keeps blends free-flowing and tablets hard — no caking in the jar, no softening in the blister pack.
Non-cariogenic and low glycemic: Supports tooth-friendly and diabetic-friendly product claims.
Half the calories of sugar (~2 kcal/g): Enables 50% calorie reduction claims.

1. Tabletop Sweeteners — The Core ST80 Application
ST80 is the carrier backbone of granulated and powdered sugar substitutes. Its role is both functional (bulk, flow, dispersion) and sensory (bitter-masking, mouthfeel):
Spoon-for-spoon granulated sweeteners: ST80 + HIS (sucralose, stevia, or aspartame-acesulfame) blended to match sugar's sweetness per teaspoon. ST80's fine particles ensure the micro-gram quantities of HIS are uniformly distributed through every gram of product.
Powdered sweetener sachets: The fine particle size dissolves instantly in hot beverages — no residue, no graininess.
Sweetener tablets: Direct-compressed into convenient tablet format for portion-controlled use.
2. Compressed Mints & Candy Tablets
Direct compression base: ST80 compacts into tablets with clean break, smooth mouthfeel, and rapid dissolution under compression forces achievable on standard rotary presses.
Cooling + sweetness balance: Isomalt's low cooling effect means the sensory experience is sweet and smooth — ideal for fruit and vanilla-flavored compressed candies where intense cooling would be off-putting.
Non-sticky storage: Low hygroscopicity keeps tablets hard and free-flowing — no clumping in the tin.
3. Chewing Gum Coating & Dusting
Fine powder for pan coating: ST80's particle size is suited to the multi-layer coating build-up on gum centers — each syrup application followed by ST80 dusting produces the hard, crisp shell consumers expect.
Anti-sticking dusting powder: Applied between gum pieces to prevent adhesion during processing and packaging.
4. Pharmaceutical Direct Compression
Chewable tablet excipient: Non-cariogenic, mildly sweet, direct-compression-compatible — ST80 is a single excipient that replaces the filler, binder, and sweetener in chewable vitamin and antacid formulations.
USP/NF + EP compliance: supports regulatory filings in US and EU markets.
5. Dry Beverage Mixes & Nutritional Powders
Instant drink powders: Rapid dissolution, clean sweetness, no aftertaste.
Protein and meal replacement powders: Blends uniformly with protein isolates, fibers, and micronutrients — no stratification during storage.

Q: Should I use ST30 or ST80?
A: Melting and cooking hard candy → ST30 (granules melt evenly). Dry blending with HIS, direct compression, or coating/dusting → ST80. If unsure, our technical team can review your process and recommend.
Q: Can I use ST80 for hard candy?
A: Technically yes, but ST30's granular form melts more uniformly and generates less dust during handling. ST80 is not the optimal choice for cooking applications.
Q: Can Huanfa supply both grades in one container?
A: Yes. Split container loads of ST30 + ST80 available. Specify quantities when requesting quotation.
Q: Shelf life, MOQ, lead time?
A: 24 months. MOQ 1,000 kg trial, ~18–20 MT commercial. Lead time 15–20 days.
