What is Reb A?
Steviol glycosides are the sweet compounds of the stevia leaf (Stevia rebaudiana). They occur as a family — stevioside, Rebaudioside A, Rebaudioside C, Dulcoside A and others — in different proportions. Rebaudioside A (Reb A) carries the cleanest sweetness of the family, which is why it became the reference stevia grade for industrial sugar reduction.
From the molecular structure
Reb A carries four glucosyl units on the steviol backbone, one more than stevioside. That extra glucose unit is what removes most of the lingering bitterness: the sweet taste is fuller and the bitter aftertaste far shorter than stevioside at the same dose.
Stevioside — three glucosyl units
Rebaudioside A — four glucosyl unitsFrom the processing procedure
Stevia dry leaves are soaked in food-grade ethanol and purified water; the crude extract is then separated on resin, eluted, concentrated and spray-dried. The result is a white crystalline powder that is 200–300 times as sweet as sucrose, with no calories and no glycaemic load.
Extraction, purification, crystallisation
Leaf → soaking → resin absorption → elution → concentration → spray drying → blending → packing. Each step runs under a documented CCP plan, and a lot is released only after in-house HPLC release testing, with third-party verification on request.
Where Reb A is used
Carbonated and still beverages, RTD tea and coffee, flavoured water, dairy and plant-based drinks, tabletop sweeteners, bakery fillings, sauces, pickles and canned fruit. For applications that do not need high sweetness intensity — pickled and spicy foods, for example — SG95-RA60 usually gives the lower cost per unit of sweetness.
Reb A or Reb M — which one to choose
Both are steviol glycosides extracted from the stevia leaf. Reb A gives the lower cost per unit of sweetness; Reb M gives the cleanest taste and tolerates higher dose before any bitterness appears. Many customers start with Reb A and move part of the formula to Reb M for the front-of-pack claim.
| Reb A 97% | Reb M 95% (Optimvia® RM95) |
|---|
| Main glycoside | Reb A ≥97% | Reb M ≥95% |
| Sweetness at 5% SE | 280× | 300× |
| Bitterness | Noticeable from about 200 ppm | Hardly noticeable even above 300 ppm |
| Taste profile | Clean, close to sucrose, slight linger at high dose | Closest to sucrose, no lingering aftertaste |
| Relative cost | Lower | Higher |
| Typical use | Mainstream sugar reduction in beverages, dairy, bakery | Clean-label formulas, premium beverages, low-dose systems |

How our Reb A and Reb M are made — both production routes
This is the first question most purchasing teams ask, because the route decides the clean-label claim you can carry. We operate both routes, so we can quote either one for the same project:
1. Leaf extraction (EU E 960a)
Stevia leaves → water / food-grade ethanol extraction → resin purification → crystallisation. All GLSTEVIA® RA grades are made this way. The leaf supply comes from our own GL#10 cultivar plus contract planting, so the botanical origin is traceable to field level.
Claim available: “Rebaudioside A from stevia leaf extract”, natural origin, non-GMO.
2. Enzymatic bioconversion (ESG)
Steviol glycosides → glucosyl transfer with CGTase → glucosyl steviol glycosides (GSG). Melis300™ and GLF03® GSG75 are produced this way, and Optimvia® RM95 / RD95 are made on the same enzymatic platform — never by fermentation. The enzyme route raises solubility above 20% w/v and pushes sweetness to 80–160× depending on grade, at a lower cost than Reb M.
Regulatory status: EU E 960c, authorised as enzymatically produced steviol glycosides.
If your specification fixes one of the two routes, say so at enquiry stage — we confirm in writing which route your grade comes from, before the order is placed rather than after.

Frequently asked questions
The questions below are specific to this grade. The stevia FAQ answers 36 more — sweetness equivalence, bitterness and masking, both production routes, organic certification, MOQ, lead time and payment terms.
What is Reb A and how does it differ from stevioside?
Reb A (Rebaudioside A) is one of the steviol glycosides found in the stevia leaf. It has four glucosyl units on the steviol backbone, one more than stevioside, which makes its sweetness fuller and its bitter aftertaste much shorter. Reb A is the reference grade for industrial sugar reduction; stevioside is cheaper per kilo but noticeably more bitter at the same sweetness.
Should I choose Reb A 97% or Reb A 98%?
The difference is one percentage point of assay, about 20 times the sweetness at 5% SE, and a modest price step. RA97 is the right choice for most beverages, dairy and bakery formulas. Choose RA98 when a label claim needs Reb A at or above 98%, or when the application is sensitive to the last trace of bitterness.
Reb A or Reb M for my application?
Reb A gives the lower cost per unit of sweetness and works for mainstream sugar reduction. Reb M is closer to sucrose and stays clean at higher dose, so it suits premium and clean-label formulas. A blend of the two is common: Reb A for the bulk of the sweetness, Reb M to remove the linger.
Is your Rebaudioside M leaf-extracted, bioconverted or fermented?
Enzymatically converted from leaf steviol glycosides, and never fermented. Reb M is only about 0.1% of the glycosides in the leaf, so a 95% grade is made by converting leaf glycosides with a food-grade enzyme preparation and then purifying - the EU category E 960c. The GLSTEVIA RA series is straight leaf extraction (E 960a); the GSG range (Melis300, GLF03 GSG75) uses the same enzymatic platform. Tell us at enquiry stage if your specification fixes a route, and we confirm it in writing.
Do you supply organic Reb A?
Yes. Our Reb A 97% is available as a USDA NOP certified organic grade, produced under the organic planting and processing programme and certified by LETIS. The organic certificate and lot documentation are supplied with the order. Tell us the destination market at enquiry stage so we confirm the standard that your labelling requires.
What is the MOQ and can I get a sample?
MOQ is 20 kg per grade, and mixed pallets combining several grades are accepted. A 50 g sample per grade is free of charge and is dispatched within 3 working days.
What is your lead time?
3 to 7 days for standard grades held in stock, counted from order confirmation. Custom blends and non-standard assays are quoted with their own lead time at order confirmation.
Which documents come with a shipment?
Batch-specific COA, specification sheet, SDS, allergen, GMO and TSE-BSE statements, heavy metal and microbiological reports, Halal and Kosher certificates, country of origin, shelf-life statement and, for organic lots, the organic certificate. Third-party test reports are available on request.
