R&D Insights: Overcoming Bitterness & Licorice Aftertaste in Sugar-Reduction Projects
A practical application review from our senior food application scientists.
Formulating zero-sugar or reduced-sugar products with Stevia often comes with a well-known technical challenge: lingering metallic bitterness, slow onset sweetness, and a herbal licorice backnote that consumer focus groups pick up immediately.
We solve these sensory and solubility roadblocks through targeted glycoside isolation and biotransformation technologies. By supplying high-purity Reb-A 98%, next-generation Reb-M/Reb-D, and Enzyme-Modified Stevia (Glucosyl Steviol Glycosides), we help developers achieve a quick sugar-like sweet curve without harsh off-tastes, ensuring high consumer acceptance across low-pH beverages, dairy products, and baked goods.

Frequently Asked Questions (FAQ)
Q1: How does Stevia Reb-A compare to Reb-M in formulation applications?
A: Reb-A is the most widely used steviol glycoside, offering high sweetness cost-efficiency; however, higher concentrations can exhibit a mild licorice aftertaste. Reb-M closely mirrors real sugar with a rapid sweetness onset and almost zero bitterness, making it ideal for 100% sugar-replacement in premium beverages and dairy products.
Q2: What are the main benefits of Enzyme-Modified Stevia (Glucosyl Stevia)?
A: Enzyme-Modified Stevia undergoes enzymatic transglucosylation, which rounds out the sweetness release curve and significantly reduces natural bitter notes. It works exceptionally well as a flavor modifier and sweetness enhancer in complex matrices like protein shakes, sauces, and functional foods.
Q3: Will Stevia Powder withstand high temperatures during baking or pasteurization?
A: Yes. Steviol glycosides are thermally stable up to 200°C (392°F) and remain stable under acidic conditions (pH 2.0 to 4.0). Unlike aspartame, stevia does not break down or lose sweetness during baking, UHT treatment, or hot-fill processes.
Q4: Is Natural Stevia Extract Powder GRAS and approved for global regulatory use?
A: Yes. High-purity steviol glycosides (≥95% purity) hold FDA Generally Recognized As Safe (GRAS) status and are fully approved as food additives across the EU, EFSA, JECFA, Health Canada, ANZFA, and Asia-Pacific regulatory bodies.
