FAQ

Q: What's the difference between quercetin and rutin?

A: Rutin is quercetin linked to rutinose, a disaccharide. It's water-soluble yet digested by gastrointestinal enzymes.

Our product, Quercetin, is the sugar-free active form, the aglycone. Though less water-soluble, it is more bioavailable in supplements. Compared to rutin, studies show improved tissue absorption.

For supplements, quercetin is best. For water-soluble beverages, rutin may be better.

Q: How do I solubilize quercetin in liquid formulations?

A: Native quercetin is poorly water-soluble (pH-dependent). Solutions:

1. pH adjustment – Soluble in alkaline solutions (pH 8-10)

2. Complexation – Use with cyclodextrins (β-CD or HP-β-CD)

3. Emulsification – Lecithin, polysorbate, or Quillaja extract

4. Nano-delivery – Liposomal or micelle systems

Our R&D team can recommend specific approaches based on your formulation. We maintain relationships with solubilizer suppliers if needed.

Q: Will this extract survive my manufacturing process?

A: Quercetin shows good stability under:

· Tableting: Compression forces up to 20 kN

· Encapsulation: No degradation in gelatin or HPMC capsules

· Heat: Stable to 180°C for 20 minutes (ideal for bars/baking)

· Pasteurization: Retains potency through HTST processing

Avoid extended exposure to:

· Strong UV light (use amber packaging)

· High pH (>10) for extended periods

· Oxidizing agents (ferric iron, peroxides)

We can provide stability data for your specific conditions.

Q: Do you offer organic certification?

A: Yes. Our product is available with USDA Organic and EU Organic (Reg 2018/848) certification. Organic lots require 500kg minimum order with 3-week lead time. Contact us for current availability and pricing.
