What Makes Our Roselle Extract Different?
Our manufacturing process is managed by GMP centered management systems to ensure each batch satisfies worldwide standards. We closely regulate the entire production chain to provide clean label ingredients.
Our parameters are configurable from 10% to 60% polyphenols for your advantage. This versatility helps you to meet your specific formulation needs and cost aims.
The main features are:
- Standardized polyphenol content verified by UV spectroscopy
- High anthocyanin concentration from delphinidin-3-sambubioside and cyanidin-3-sambubioside
- Rich organic acid profile including citric, malic, and tartaric acids
- pH-dependent color stability optimal between 2.5-4.0
- Superior oxygen radical absorbance capacity (ORAC) value
Our extraction technology preserves chlorogenic acid, caffeic acid, protocatechuic acid, and flavonoids like quercetin and kaempferol. These compounds work synergistically to enhance the functional benefits of your finished products.

Versatile Applications Across Industries
Functional Beverages & Ready to Drink (RTD) Drinks
Our Roselle Extract performs well in acidified matrix compositions such as kombuchas, energy drinks and functional waters. It substitutes for manufactured Red 40. It provides natural tartness that covers high-intensity sweets. Stable at low pH (2.5-3.5) to maintain brilliant color over shelf life.
Dietary Supplement
You can make robust health supplements for the cardiovascular system and urinary tract. High-concentration polyphenols provide therapeutic level benefits in capsule and tablet forms. We give precise humidity control recommendations for encapsulation techniques.
Candies & Gummies
The extract can be used as a natural, strong coloring for acidic gummy compositions. Its high organic acid concentration is a complement to berry and citrus flavor characteristics and reduces color fade during processing.
Functional Foods

FAQ
Q: Why does the extract sometimes clump during storage?
A: The high organic acid content makes the powder hygroscopic. Store in tightly sealed, aluminized bags below 25°C with relative humidity under 60% to prevent clumping.
Q: Can it replace synthetic colorants in bakery products?
A: Yes, with considerations. The anthocyanins are heat-sensitive above 180°C. We recommend it for fillings and icings, or use our microencapsulated version for high-temperature baking applications.
Q: Why did my beverage turn blue instead of red?
A: This occurs when the matrix pH exceeds 3.8. Anthocyanins undergo a bathochromic shift in neutral or alkaline conditions. Maintain pH below 3.8 for stable red color.
Q: What's the recommended dosage for functional benefits?
A: Clinical research suggests 10-15mg anthocyanins or 250mg standard extract daily for cardiovascular support. Typical formulation concentrations range from 0.5% to 2% w/w depending on your application.
Q: Is the extract fully water-soluble?
A: Yes, high-quality grades achieve 100% solubility. We minimize silica flow agents (<1%) to prevent sediment in clear liquid applications.
