Product Introduction
Orange Peel Flavonoid – High-Purity Citrus Extract for Nutraceutical and Functional Food Applications
Using HPLC analysis, Kang Biotech provides pharmaceutical-grade Orange Peel Flavonoid with 80%–98% purity. We have 11 years of citrus extraction experience and 20,000,000 m² of maintained bitter orange farms in Lianyuan, Hunan Province. Our 9 modern manufacturing lines provide consistent batch-to-batch quality. High PMF contents, including Nobiletin and Tangeretin, make our extract bioavailable and lipophilic. ISO 9001, ISO 22000, HACCP, Halal, Kosher, and FAMI-QS credentials ensure food, nutraceutical, pharmaceutical, and feed compliance in 40+ worldwide markets.
What Is Orange Peel Flavonoid?
Citrus exocarp bioactive phytonutrients are enriched in our product. This extract includes PMFs like Nobiletin and Tangeretin, unlike citrus bioflavonoids. Fatophilic methoxy groups improve cellular membrane penetration and absorption.
This extract solves many problems in the nutraceutical and functional food industries: poor antioxidant bioavailability, clean-label metabolic regulators, and blood-brain barrier substances. The tailored physiological influence on lipid metabolism and inflammatory pathways makes it a better citrus extract option.

Key Properties and Technical Advantages
Our extract is thermally stable and has a methoxy-group structure. Formulations that need effective nutrition delivery benefit from this configuration's increased cellular permeability. HPLC quantifies standardized extracts at 30%–98% PMFs.
The light yellow to golden-brown powder has a little bitterness and woody, flowery base aromas. Melting points are usually 135°C to 160°C. This extract resists oxidation during high-temperature food processing, preserving product integrity in harsh production situations.
USP and EP botanical extract quality standards are followed. Ash and moisture remain below 1% and 5%, respectively. These criteria enable long-term stability and compatibility with lipid-soluble nutrients like Omega-3s.
Application Scenarios
Orange Peel Flavonoid has three high-performance uses:
1. Health Supplements Metabolic
Capsules and tablets for LDL cholesterol and insulin sensitivity. In metabolic health products, its capacity to down-regulate hepatic fatty acid production is crucial.
2. Functional Drinking Systems
Used in clear RTD teas and energy drinks by micro-emulsification. This guarantees clarity and stability in acidic pH conditions (pH 2.5–4.0), matching customer expectations for clean-label, attractive products.
3. Advanced Derm-Cosmetics
In topical serums to inhibit tyrosinase and deliver UV-protective antioxidants. The extract is stable in complicated oil-in-water emulsions without recrystallization, maintaining skincare formulation performance.
Quality Control and Safety Standards
To achieve accurate Nobiletin and Tangeretin ratios, HPLC-DAD quality control is rigorous. Critical inspection items:
1. Pesticide Residue Screening: EU and FDA citrus crop MRL compliance.
2. Ethanol and ethyl acetate levels found within USP <467> limits in solvent residue analysis.
3. Heavy Metal Quantification: ICP-MS analysis reveals Lead (Pb) <1ppm, Arsenic (As) <1ppm, and Mercury (Hg) <0.1ppm.
4. Synephrine-Free Verification: Required for heart-health formulations to avoid adrenergic stimulants.
5. Microbiological Purity: <1000 cfu/g Total Plate Count, no E. coli or Salmonella.
Product optimization and compliance with changing international requirements are supported by our Joint Research Center with the Hunan Institute of Agricultural Product Processing and Quality Safety.
Packaging and Delivery
Standard packaging is 25 kg fiber drums, with OEM/ODM customization available for specifications, purity levels, labeling, and packaging design. Ready stock supports fast shipment. Small quantities ship via FedEx, while bulk orders are transported by air or sea freight to accommodate diverse logistical requirements.
FAQ
Q1: How does it vary from Hesperidin?
A: This extract has lipophilic methoxy groups, unlike Hesperidin. This increases absorption and cell membrane penetration.
Q2: Has beverage water solubility?
A: Carrier-complexation (e.g., cyclodextrin) makes lipophilic grades water-dispersible for complete solubility in aqueous solutions.
Q3: Shelf life and storage?
A: The shelf life is 24–36 months in sealed packaging in a cold, dry environment. Avoid direct sunshine and humidity.
Q4: Are there any known contraindications?
A: CYP450 enzyme metabolism may be affected by high dosages. Clinicians suggest drug-nutrient interaction testing.
Q5: How do you authenticate extracts?
A: We use HPLC fingerprinting to verify that samples are from Citrus reticulata and not synthetic replacements.
