High-purity stevia rebaudioside A (Reb A) is a concentrated steviol glycoside sweetener derived from Stevia rebaudiana. It is designed for use in food, beverage, active nutrition, and health formulations requiring high-intensity sweetness at low inclusion levels.
Key Product Characteristics
High sweetness intensity (approximately 200–300 times sweeter than sucrose)
Derived from high-grade Stevia rebaudiana leaf extract
Available in customizable purity grades (Reb A 60% to 98%)
Dry powder format with options for standard fine powder, low-dust, or granulated versions
Compatible with reduced-sugar, zero-sugar, and low-calorie formulations
Thermal and pH stability across standard food and beverage manufacturing processes
Certified for global compliance (FDA GRAS, EFSA, JECFA, Halal, Kosher, Non-GMO)

Grade Selection Criteria
Sweetness & Flavor Balance: Higher Reb A purity (97%+ or 98%) provides a cleaner sweet taste with minimal lingering bitterness. Mid-purity grades (60% to 80%) offer strong sweetness at a lower cost-in-use.
Processing & Dissolution: Liquid formulations benefit from high-solubility fine powders, while dry mix manufacturing may require low-dust or granulated formats for optimal flowability.
Bulk & Texture Replacement: Because high-intensity sweeteners do not provide volume, substantial sugar replacement in solid foods requires pairing Reb A with suitable bulking agents.
Target Applications
Reduced-Sugar Beverages
Used in carbonated soft drinks, ready-to-drink (RTD) teas, functional waters, juice drinks, and powdered beverage mixes. Performs reliably across typical processing pH levels.
Dairy and Plant-Based Products
Applied in yogurts, flavored milks, ice creams, and dairy alternatives. Stable under pasteurization and standard dairy processing conditions.
Confectionery and Bakery
Provides sweetness in gummies, hard candies, chocolates, jellies, and bakery fillings. Requires structural bulking agents when replacing substantial sucrose weight.
Nutrition and Supplements
Ideal for sports protein powders, amino acid formulas, dietary supplements, and meal replacement shakes requiring a low-glycemic sweetener profile.
Manufacturing and Quality Assurance
Sourcing Verification: Raw stevia biomass is screened against strict pesticide residue and identity standards.
Analytical Verification: High-Performance Liquid Chromatography (HPLC) is used to verify exact Reb A purity and total steviol glycoside ratios prior to batch release.
Traceability: Each shipment carries a dedicated lot number linked to full production, raw material, and laboratory analysis records.

FAQ
Q: What is the most critical technical parameter to specify when purchasing Reb A?
A: The Reb A assay percentage (determined by HPLC) is the primary specification, as it directly dictates sweetness intensity, taste profile, and formulation cost-in-use.
Q: Does a higher Reb A purity always result in a better product?
A: Not always. While higher purity grades (Reb A 97% to 98%) yield the cleanest flavor profile, lower or mid-grade specifications (Reb A 60% to 80%) often provide adequate sensory performance in heavily flavored systems at a lower cost-in-use.
Q: Can Reb A replace sugar on a direct 1:1 weight basis?
A: No. Reb A is a high-intensity sweetener that is 200 to 300 times sweeter than sugar. It provides sweetness at very low dosages but does not replace the bulk, mouthfeel, volume, or browning properties of sucrose.
Q: Are granulated or instant-dissolving versions available for industrial handling?
A: Yes. Standard fine powders can create dust during large-scale dry blending. Granulated or agglomerated grades are available to improve powder flowability, reduce processing dust, and accelerate cold-water dissolution rates.
Q: What documentation is provided for commercial market clearance?
A: Every commercial batch is supplied with a comprehensive documentation package, including an HPLC-verified COA, Product Specification Sheet, SDS, allergen/GMO declarations, and applicable Halal, Kosher, and food safety certifications (such as ISO/FSSC 22000).
