What is Orange Peel Bioflavonoid?
A complex set of polyphenolic chemicals from Citrus sinensis pericarp is our product. Other flavonoids enhance the bioactivity of hesperidin.
Nutraceuticals recognize this citrus-derived substance as a plant-based functional component. This formulation solves bioavailability, oxidative stability, and clean-label ingredient issues.
For bioactive preservation, we use water or ethanol extraction. You'll get a reliable ingredient for health products.

Quality Control
Every batch of the product fulfills worldwide standards thanks to our stringent quality management system. HPLC analysis verifies Citrus sinensis source and hesperidin content.
Solvent residue testing shows ethanol levels are significantly below ICH Q3C. ICP-MS heavy metal profiling ensures Proposition 65 and EU lead, cadmium, and mercury compliance.
Synthetic flavonoids or inferior citrus species can be detected by TLC/HPTLC fingerprinting. You can trust our extensive testing methodology to preserve products.
Our Joint Research Center with the Hunan Institute of Agricultural Product Processing and Quality Safety promotes quality improvement. This alliance improves our extraction optimization and product standardization skills.

Functional Applications
Orange Peel Bioflavonoid has several industrial uses:
Cardiovascular health supplements use it to support capillary function and vitamin P action. The substance works in complicated multi-ingredient capsules and tablets.
Water-dispersible grades that resist precipitation are used in energy and health drinks. Despite ultrahigh processing temperatures, our extracts remain clear.
Supplements with vitamin C and other antioxidants boost bioavailability and synergy. Hesperidin enhances intracellular absorption and prevents ascorbic acid oxidation.
Healthy Products: Used in circulation and health formulations. Plant-based functional ingredient consumers like citrus' natural nature.

FAQ
Q: What about liquid applications' inherently poor water solubility?
A: We use micronization (d90 <10μm) or cyclodextrin encapsulation to improve water dispersion without surfactants.
Q: What is the shelf-life stability of the active components?
A: Accelerated stability testing shows that hesperidin remains >98% stable for 36 months in airtight, light-protected storage at 25°C.
Q: Does your extract include synephrine?
A: No, our extraction technique carefully eliminates alkaloids like synephrine to avoid stimulant issues.
Q: How does it synergize with vitamin C?
A: Bioflavonoids prevent ascorbic acid oxidation and increase intracellular absorption by 35% in clinical settings.
Q: Does it meet Non-GMO standards?
A: All batches fulfill identity preservation criteria by using non-GE citrus orchards and non-GMO processing aids.
