Rebaudioside M

At Shaanxi Rebecca Biotechnology Co., Ltd., we blend innovation with integrity to provide world-class natural ingredients.

Advanced R&D and Manufacturing Capabilities

We use today's enzymatic conversion era and multi-stage recrystallisation techniques in our facilities. This ensures that you acquire consistent, excessive purity merchandise, batch after batch.

Rigorous Quality Testing

Each batch is tested for purity, heavy metals, pesticide residues and microbiological safety using HPLC, ICP-MS and microbial analysis techniques. Third party testing available upon request.

Supply Chain Traceability

We obtain non-GMO stevia leaves from traceable farms to FDA and JECFA requirements. Every every batch is fully documented, ensuring complete transparency in the supply chain.

Customisable Flexibility

Standard powder, cyclodextrin modified water-soluble or bespoke particle sizes, we can customise to your formulation needs. We can provide OEM and ODM service.

The Global Logistics Network

We have a completely powerful deliver chain that allows us to deliver quickly and securely throughout the globe. We take care of all export papers and support to make your buying technique easy.

Raw Material Origin

Rebaudioside M naturally occurs in stevia leaves at only 0.4%–1%, making direct extraction impractical. We use high-purity Rebaudioside A as a substrate for enzymatic conversion, a mainstream industrial method that ensures scalability and cost-effectiveness.

Supply Chain Grades

· Standard Field-Grown Stevia: Used for conventional total glycoside extraction and enzyme substrates

· Non-GMO Traceable Stevia: Full pesticide residue testing, compliant with EU and US standards, processed on independent lines to avoid cross-contamination

· High-Purity Reb A Substrate: The core starting material for enzymatic synthesis, ensuring high conversion rates and minimal impurities'

Solubility Characteristics

· Crystalline Form: Limited cold water solubility (~0.1g/100mL at 25°C); readily soluble in hot water and dilute ethanol

· Amorphous Form: Solubility increases to 1.1%–1.3% at room temperature

· Cyclodextrin-Modified Version: Rapid dissolution in hot or cold water, producing clear solutions ideal for transparent beverages and oral liquids

Stability Highlights

· Temperature: Excellent dry powder stability; aqueous solutions withstand 180°C for 30 minutes with only ~3.2% degradation

· pH Range: Stable between pH 4.0–8.0; avoid strongly acidic (<3) or alkaline environments

· Light Exposure: Store sealed in light-proof packaging to prevent slow degradation

· Moisture Control: Vacuum-sealed aluminum foil bags ensure 24-month shelf life unopened

We implement strong quality control procedures at every step of our manufacturing process:

Substrate Preparation: High grade Reb A is dissolved in purified water at controlled temperature and pH and filtered to remove contaminants.

Enzymatic Conversion: UDP-glycosyltransferase enzymes are employed to transfer glucose units onto Reb A directionally, and HPLC is used to monitor the process until desired conversion is reached. Then the enzymes are disabled.

Flocculation & Filtration Food grade flocculants assist in the removal of residual proteins and polysaccharides. Plate filtering produces a clear crude solution.

Ion Exchange Desalting: Clarity is improved by using cation and anion exchange resins to remove salts, pigments and polar contaminants.

Resin Enrichment: Macroporous adsorption resin adsorbs Reb M and gradient ethanol elution separates unconverted Reb A and heteroglycosides.

Concentration: Low temperature ( 65 °C) vacuum concentration is used to recover ethanol and leave a crude Reb M extract.

Recrystallisation Grading: This key stage determines final purity:

· ≥95%: Single recrystallization

· ≥98%: Dual gradient recrystallization

· ≥99%: Preparative chromatography plus multiple recrystallizations

Crystal Washing & Drying: Cold solvent washing, centrifugal dehydration, low temperature vacuum drying in the dark.

Optional Modification: Cyclodextrin inclusion technology enhances the solubility in cold water for some applications.

Final Steps: grinding, sieving, homogenisation, sealed packaging and complete batch testing before warehousing.

Compositions for Beverages

Developed for carbonated soft drinks, plant-based milks and functional drinks. It locks in sweetness in acidic conditions and hides off-notes in protein drinks.

Baking & Sweets

It’s heat-stable, perfect for cookies, cakes, and sugar-free candies with no flavour loss.

Dietary Supplements

A high sweetness intensity enables effective sweetening of protein powders, meal replacements and pre-workout formulae without compromising the glycaemic index.

Milk Alternatives

Improves creaminess in oat, almond and soy based products and neutralises earth like flavours.

Diabetic & Keto Friendly

Zero-calorie, non-glycemic profile meets specialised diet and clean-label claims

Certification Systems: ISO9001, HALAL, KOSHER, FSSC22000, HACCP, Non-GMO, Vegan

Testing Capabilities: HPLC purity assay Heavy metal testing (Pb <1ppm, As <1ppm) Microbial safety (Salmonella and E.coli negative) Residual solvent analysis

Third Party Verification: Available on request for regulatory compliance and consumer confidence

Traceability: Complete documentation from raw material source to final product delivery

Standard Packaging: 25kg moisture-proof cardboard drums with vacuum-sealed, light-proof inside aluminium foil bags

Custom Options: Smaller retail packs, bulk totes or custom labelling for OEM/ODM orders

Shipping Methods: Air freight for samples, sea freight for big orders. Export documents given for smooth customs clearance.

Q: What’s your process of producing Reb M?

A: We use professional enzymatic conversion from non-GMO traceable Reb A, which ensures high purity, steady flavour and low contaminants.

Q: How soluble and stable is it?

A: Standard Reb M is soluble in hot water. Water-soluble forms of clear liquids have been modified. Stable at pH 4.0 – 8.0 and below 190°C, with a shelf life of 24 months.

Q: Do you have a steady bulk supply?

A: Yes. We carry factory direct tonne level stock, neutral export packaging and full documentation. Free replacement for any confirmed quality concern.

Q: Suitable for high temperature processing?

A: Definitely. It is not degraded and is resistant to industrial baking and UHT sterilisation.

Q: Can it be used in combination with other sweeteners?

A: Yes. It can be used with erythritol or allulose to provide bulk and mouthfeel similar to sugar in zero calorie compositions.
