Reliable Stevia Extract Manufacturer & Bulk Supplier
Greenherb operates a certified processing facility specializing in Stevia Extract, a natural zero-calorie sweetener ingredient derived from the leaves of Stevia rebaudiana through controlled aqueous extraction and chromatographic purification. Our production system delivers consistent rebaudioside A standardization, verified steviol glycoside identity, and batch-level documentation. This provides food manufacturers, beverage developers, and supplement formulators with a dependable supply of this widely regulated natural sweetener ingredient.

Why Choose Greenherb Stevia Extract
Rebaudioside A Standardization by HPLC
Each production batch is verified against a defined Reb A specification. Rebaudioside A delivers the cleanest sweetness profile among steviol glycosides. Consistent Reb A loading supports predictable sweetness intensity in finished food and beverage formulations.
Multiple Steviol Glycoside Specifications
We offer a range of Reb A concentration tiers from standard 80% through high-purity 98% specifications. Lower concentration tiers retain co-occurring stevioside for a more complex sweetness character. Higher tiers deliver cleaner, more neutral sweetness suitable for premium product applications.
Regulatory Acceptance Across Major Markets
Steviol glycosides are approved food additives across EU, US, Codex Alimentarius, and Asian market regulatory frameworks. Our extract meets the purity requirements defined in each regulatory framework. Compliance certificates are available for major international market submissions.
Zero Caloric Contribution
Steviol glycosides are not metabolized for caloric energy. They pass through the digestive tract without contributing to caloric intake. This supports calorie-reduced and zero-sugar product positioning across food, beverage, and supplement label formats.
Water-Soluble Powder Format
The spray-dried extract disperses readily in aqueous systems. It dissolves at room temperature without heating. This supports direct incorporation into beverage premixes, confectionery coatings, and functional food dry blends.
Heavy Metal and Pesticide Compliance
Every lot undergoes ICP-MS heavy metal screening and GC/LC-MS pesticide residue analysis. Results are verified against EU and US regulatory thresholds before release.
Complete Export Documentation
Each shipment includes COA, MSDS, steviol glycoside compliance certificate, allergen declaration, and Non-GMO affidavit. These support regulatory submissions across international food and supplement markets.

What Is Stevia Extract
The Sweetening Compounds of Stevia rebaudiana
Stevia rebaudiana leaves contain a complex mixture of diterpene glycosides collectively called steviol glycosides. These compounds are 200–400 times sweeter than sucrose on a weight basis. Rebaudioside A is the most abundant glycoside in high-quality leaf material. It delivers the sweetest and cleanest flavor profile among the major steviol glycoside compounds. Stevioside is the second most abundant glycoside and contributes a slightly more bitter aftertaste character.
Extract vs. Stevia Powder
Stevia powder describes a range of preparations from dried leaf powder through highly purified steviol glycoside extract. Crude stevia leaf powder contains only 6–10% steviol glycosides alongside leaf fiber and chlorophyll. Stevia Extract undergoes aqueous extraction and chromatographic purification to concentrate the steviol glycoside fraction to defined Reb A specifications. This delivers a consistent sweetness intensity per gram that crude stevia powder cannot provide for commercial food and beverage applications.
Sweetness Profile Management
Not all Stevia Extract preparations taste identical. Steviol glycoside composition directly influences the sweetness onset, intensity, and aftertaste character of the finished ingredient. Higher Reb A specifications deliver sweeter, cleaner sweetness with reduced aftertaste. Standard specifications retaining stevioside contribute a more complex, slightly bitter sweetness character. Understanding this composition-flavor relationship helps formulators select the appropriate specification for their specific product concept.

Production Process
Leaf Sourcing and Qualification
Incoming Stevia rebaudiana leaves are assessed for botanical identity, total steviol glycoside content, Reb A percentage, moisture, heavy metals, pesticide residues, and microbiological status. Only material meeting incoming specification proceeds to extraction.
Aqueous Extraction
Qualified dried leaf material undergoes hot water extraction under controlled temperature and time parameters. This selectively solubilizes the water-soluble steviol glycoside fraction from the leaf matrix.
Clarification and Decolorization
Crude extract undergoes multi-stage filtration, activated carbon decolorization, and membrane filtration. These steps remove chlorophyll, leaf pigments, and particulate matter, producing a clarified, nearly colorless glycoside solution.
Chromatographic Purification
Clarified extract undergoes ion exchange and adsorption chromatography to concentrate the Reb A fraction. This separates the target glycosides from co-extracted minor glycosides and non-glycoside compounds, achieving the target Reb A specification.
Standardization and Crystallization
Purified steviol glycoside stream is measured by HPLC for Reb A content. Where crystalline formats are required, controlled crystallization produces uniform Reb A crystals. Blending achieves the final target specification.
Spray Drying
Standardized extract is spray-dried at controlled temperatures. This produces a uniform white to off-white free-flowing powder with defined particle size and moisture specification.
Quality Release Testing
Each lot undergoes HPLC steviol glycoside profile analysis, Reb A content verification, moisture, heavy metals, pesticide residues, and microbiological panel testing before batch release.
Protective Packaging
Powder is sealed in double-layer PE inner bags with desiccants. Drums are moisture-barrier sealed and light-proof. This maintains glycoside stability and prevents moisture uptake during storage and transit.

Functional Properties & Benefits
Zero-Calorie Natural Sweetness
Stevia Extract delivers intense sweetness without caloric contribution. This supports product positioning across calorie-reduced, zero-sugar, and weight management food and beverage formulations where sugar reduction is a primary label claim objective.
Blood Sugar Comfort Support
Steviol glycosides are not absorbed as glucose and do not contribute to postprandial blood sugar response. Functional food and supplement formulations targeting blood sugar comfort and glycemic management incorporate Stevia Extract as a primary sweetening ingredient.
Dental Comfort and Oral Wellness
Unlike fermentable sugars, steviol glycosides do not serve as a substrate for oral bacteria. This supports dental comfort and oral wellness positioning for Stevia-sweetened confectionery, gum, and functional food products targeting oral health concepts.
Keto and Low-Carbohydrate Diet Compatibility
Stevia Extract is compatible with ketogenic and low-carbohydrate dietary frameworks. Supplement and functional food products targeting these dietary patterns incorporate stevia as the preferred sweetening ingredient. It delivers acceptable sweetness without disrupting carbohydrate-restricted nutritional approaches.
Clean Label Consumer Appeal
Plant-derived botanical origin and established regulatory acceptance position Stevia Extract as a recognized natural ingredient. Consumer preference for recognizable, plant-sourced ingredients in food and beverage products drives formulator demand for stevia over synthetic high-intensity sweeteners.
