Product Introduction
Bitter Masking Agent – High-Potency Taste Modifier for Pharmaceutical & Nutraceutical Formulations
Kang Biotech makes pharmaceutical-grade Bitter Masking Agent from premium citrus bioflavonoids, including HPLC-verified 98% pure Neohesperidin Dihydrochalcone (NHDC). Our production facility in Hunan Province manufactures thermally stable, pharmacologically inert flavor modifiers that decrease T2R receptor activation at pH 2.0-7.0, with 11 years of experience and 20,000,000 m² of controlled bitter orange plantations.
Our ISO 22000, HACCP, Halal, Kosher, and FAMI-QS-certified product has 1,500–1,800 times the sweetness of sucrose without calories. With samples and timely delivery from reliable inventory reserves, minimum order is 1 kilogram.

What Is a Bitter Masking Agent and How Does It Work?
Products are organoleptic additives that neutralize or reduce bitter taste in pharmaceutical APIs, botanical extracts, and functional food ingredients. Instead of adding sweetness, these drugs inhibit T2R bitter receptors, complex, and interfere with signals.
NHDC-based solutions address industrial issues such low patient compliance in pediatric antibiotic suspensions, metallic aftertaste in BCAA supplements, and sensory limits in high-protein nutrition products. It achieves these goals without affecting base formulation therapeutic effectiveness or chemical stability.
More slowly than typical sweeteners, the agent changes flavor cleanly and long-term. Orally dissolving pills and liquid suspensions need regular sensory protection during oral transit, which this length provides.
Technical Properties and Quality Standards
Kang Biotech's product is ideal for pharmaceutical and nutraceutical applications due to its technical specifications.
NHDC is thermally stable up to 200°C, making it ideal for spray drying, hot-melt extrusion, and high-temperature processing. Acidic drinks, neutral pills, and alkaline preparations work consistently due to the pH stability range (2.0–9.0).
With potency at 0.1–0.3% w/w, the agent reduces product volume, texture, and production costs. Pharmacologically inactive and systemically insoluble due to high molecular weight.

Core Advantages for Your Formulations
1. High Efficacy with Low Dosage Requirements
At 0.1–0.3% inclusion rates, our chemical suppresses bitterness well, decreasing formulation costs and maintaining product quality. This efficiency makes it appropriate for cost-sensitive pharmaceutical and supplement applications.
2. Sweetner Synergy
NHDC combines with other sweets to improve sweetness, minimize off-notes, and reduce sweetener use. Taste characteristics can be improved while fulfilling clean label standards.
3. Better Processing Stability
The thermally stable substance masks effectively during spray drying, tableting, and extrusion. Your manufacturing batches will perform reliably without sensory deterioration.
4. Clean Label, Natural Origin
Our product, extracted from citrus bioflavonoids using water or ethanol, meets current customers' Non-GMO, natural ingredient, and organic standards.
Key Applications Across Industries
Pharmaceutical Oral Formulations
In pediatric antibiotic solutions with bitter compounds as Clarithromycin or Azithromycin, our drug prevents initial bitterness, ensuring full dosing delivery. This greatly increases patient compliance in taste-sensitive groups.
Sports Nutrition and Functional Supplements
In BCAA powders and pea protein isolates, it neutralizes metallic and earthy aromas that deter consumers. Clean flavors encourage recurrent sales in competitive supplement marketplaces.
Tablets that dissolve orally
Within 15–30 seconds, the Bitter Masking Agent protects rapid-dissolve formats. NHDC is vital for product development since traditional flavoring methods fail in low-moisture ODT circumstances.
Functional Dairy and Beverages
In low-calorie, plant-based dairy, and fortified drinks, it masks botanical extract harshness and boosts sweetness. Taste is consumer-preferred without excessive sweetness loading.
Quality Control and Analytical Testing
Kang Biotech rigorously controls quality to assure batch-to-batch uniformity and regulatory compliance for every product distribution.
Electronic Tongue (E-Tongue) sensory profiling objectively assesses bitterness reduction percentages compared to control samples. HPLC/GC-MS purity analysis detects no residual solvents or degradation products.
Laser diffraction monitors particle size distribution for homogeneous solid dose dispersion. Heavy metal screening by ICP-MS satisfies strict worldwide pharmaceutical requirements.
Fast stability testing at 40°C/75% RH ensures masking performance across your product's shelf life, even in complicated chemical conditions. This extensive testing ensures constant ingredient performance from research to commercialization.

Packaging and Logistics
Standard packaging: 25 kg/fiber drum with double food-grade PE bags. Private labeling and lower pack sizes are available for custom packaging.
Shipping choices include FedEx, air freight for urgent orders, and sea freight for big business shipments. We stock steady inventory for fast delivery of 1 kilogram trial orders and large-scale manufacturing.

FAQ
Q: How do products vary from sweeteners?
A: Sweeteners exclusively engage T1R2/T1R3 receptors to generate sweetness, while a product targets T2R receptors or uses chemical shielding to prevent bitter compounds from attaching.
Q: Will the agent influence medication bioavailability?
A: No, pharmaceutical-grade agents are pharmacologically inactive and do not affect API dissolution or systemic absorption.
Q: Can it handle spray drying at high temperatures?
A: Spray drying and extrusion are possible with our thermally stable masking agents up to 200°C.
Q: What should be the initial dose?
A: While bitterness intensity varies, preliminary bench-top experiments start at 0.1% w/w.
Q: Are these agents Clean Label-compliant?
A: Our citrus-based product is Clean Label, Non-GMO, and organic-compliant.
