Harnessing the synergistic therapeutic benefits of highly concentrated anthocyanins and polyphenols for modern applications.
With artificial synthetic food dyes (such as Red No. 40 / Allura Red) facing severe regulatory crackdowns and consumer scrutiny globally, Roselle Extract has emerged as a premium, highly stable clean-label natural colorant alternative. Its natural deep crimson-red profile remains remarkably vibrant in acidic conditions, serving the global RTD beverage, dairy, and confectionery sectors.
From a phytomedicinal perspective, Roselle calyx extract is exceptionally rich in anthocyanins (delphinidin-3-sambubioside and cyanidin-3-sambubioside), organic acids (hibiscus acid, citric, malic), and polyphenols. These compounds act as natural ACE inhibitors, promoting healthy blood pressure levels, managing oxidative stress, and supporting metabolic health in dietary formulations.
Procuring raw botanical materials with complete traceability has transitioned from an option to a structural necessity. Brands demand verifiable botanical supply chains, heavy metal screenings, zero pesticide residue compliance, and robust extraction methodologies that preserve bio-actives without toxic solvents.
The global production of Roselle (Hibiscus sabdariffa L.) is concentrated in tropical belts (primarily North-East Africa, Central America, and parts of Southeast Asia). However, the transformation of these raw agricultural yields into standardized, bioactive-controlled powders requires complex industrial infrastructure.
As a leading supplier and factory partner, we operate on a model of vertical integration. We establish direct contract farming networks in prime cultivation areas, monitoring cultivation, crop handling, and chemical exposure from soil to harvest. By mitigating middleman logistics, we insulate international buyers from price volatility and product adulteration.
Our raw materials undergo strict validation protocols prior to loading. This includes ensuring correct species taxonomy, preventing blending with closely related Hibiscus variants, and minimizing biological loads at harvest. Raw calyces are immediately shade-dried under regulated humidity parameters to prevent heat degradation of thermal-sensitive anthocyanin molecules.
Deploying advanced pharmaceutical-grade extraction systems to guarantee standardization values.
Every single production run of Roselle Extract is standardized. Anthocyanin content (measured as cyanidin-3-glucoside equivalents) and Polyphenol profiles are fully quantified via chromatography, eliminating variability.
Our premium grade powder dissolves instantly in aqueous solutions without sedimentation, haze, or grit, making it perfect for transparent beverage formulations and liquid cosmetic bases.
Fully compliant with EU regulations (EC No 396/2005) and US EPA tolerances. Heavy metals (Lead, Arsenic, Cadmium, Mercury) are strictly maintained below international toxicological limits.
Our proprietary drying procedures prevent stickiness and clumping, ensuring optimized powder flowability, long-term stability, and easy handling during plant manufacturing processes.

Our state-of-the-art extraction facilities employ advanced technologies, including supercritical solvent and water-based methods, to preserve the full spectrum of bioactive compounds without compromising on environmental responsibility.
Quality and safety are non-negotiable. Every batch undergoes rigorous testing in our in-house laboratories, equipped with HPLC, GC-MS, and other advanced analytical instruments. We guarantee compliance with stringent international standards, including ISO, NSF, cGMP, and related certifications. Our commitment to transparency means you receive comprehensive Certificates of Analysis (CoA) for every product, ensuring traceability and peace of mind.
It’s one thing to just meet the regulations when providing ingredients, but when an ingredient supplier exceeds those standards and imposes even higher ones in its products that is a sign of a company who cares. Andy Biotech takes extra steps to ensure that our independent third-party laboratory-tested ingredients you want meet our standards as well as your own.
Our extensive portfolio features a wide range of standardized extract, ratio extract, and custom blends tailored to specific formulations. Whether you need Echinacea for immune support, Turmeric with high curcuminoid content, or innovative botanical blends for skincare, our technical team works closely with you to deliver exactly what your product requires.
Andy Biotech provide high quality Ginkgo Biloba Extract, Lycopene Tomato Extract, Lutein Marigold Extract, Aloe Vera Gel Freeze Dried powder Aloe Vera Extract and other natural ingredients to food, health and nutraceutical industries.
Andy was born in a small village close to Hanjiang River in Hanzhong Shaanxi province, China. Thirty years ago, when she was still a little child, she caught a cold, but the medical services were not available unless the family crossed over high mountains to find a hospital. Thus, Andy's grandfather first used Echinacea leaves soaked in water for her treatment, then he dug Echinacea root and shredded into pulp and squeezed the liquid for Andy to drink one spoon every two hours. Andy recovered after this treatment.
As a child, Andy watched his grandfather harness the healing power of plants in his humble garden. His ancient herbal remedies were not just treatments; they were magic. That early wonder blossomed into a profound passion for plant extracts and a deep respect for nature’s wisdom. From that time on, little Andy swore that he would help to spread all herbs all over the world to give benefit to more people.
This personal journey is the heart of Andy Biotech. It’s why Andy Biotech are dedicated to researching and delivering the purest, most effective botanical solutions for modern wellness. Andy’s lifelong vow is to honor that tradition by innovating for a healthier future, empowering lives through the timeless power of plants.
A step-by-step breakdown of how raw calyces are purified into high-density anthocyanin dry powders.
Raw dry Roselle calyces are pulverized under low-temperature parameters. Deionized water is used to extract target organic acids and anthocyanins. This process avoids organic chemical residues.
The liquid extract passes through advanced membrane filtration units to isolate large-molecular proteins, starches, and botanical fibers. This maximizes solubility in the final product.
The solution is passed through non-polar polymeric adsorbent resins. Anthocyanins and target polyphenols are concentrated, while free simple sugars are washed away.
Low-temperature vacuum drying isolates the active compounds into a uniform, highly stable red powder. Samples are immediately collected and analyzed for moisture content and biological purity.
Optimizing formulation performance under diverse regional regulatory frameworks.
Meets US FDA regulations for dietary supplements. Full heavy metals profiles (ICP-MS), microbial validation (AOAC), and pesticide multi-residue screenings (EPA) are provided with every shipment. GMO-free declarations and organic certification documents are available upon request.
Our Roselle Extract complies with EFSA's strict regulations on botanical coloring foods. As a water-extracted ingredient, it does not require an E-number (color additive designation) on labels across Europe, helping brands achieve clean-label status.
Our manufacturing sites hold active Halal and Kosher certifications. The manufacturing lines are designed to prevent cross-contamination, ensuring compliance with global dietary requirements.
Our production facilities operate under strict GMP standards and hold comprehensive global certifications to guarantee product safety and regulatory alignment.
