What Makes Our Citrus Limon Flavonoid Different?
Citrus Limon Flavonoid is a polyphenolic substance found in lemon peel and pulp. The bioactive ingredient is Eriocitrin, a lemon-specific flavanone with better water solubility than other citrus flavonoids.
In terms of Oxygen Radical Absorbance Capacity (ORAC), this natural extract is highly antioxidant. It is appropriate for beverage and supplement applications since it is structurally stable in acidic aqueous conditions (pH 3.0-4.5).
A uniform phytochemical profile is achieved by standardizing extraction. Bioavailability is higher than isolated synthetic alternatives, addressing functional formulation absorption degradation.

Key Advantages for Your Formulations
Eriocitrin is the flavonoid that makes lemon juice different. It dissolves easily in water, which means that finished products with it have better metabolic activity than those with hesperidin-rich orange extracts.
Strong free radical scavenging qualities help your formulas. Research supports its possible role in protecting antioxidants, supporting metabolic health, and maintaining liver health, all of which are important benefits for making health-focused products.
The thermal stability stays the same up to 85°C when processing for a short time. This means that our ingredient can be used to make sterilized drinks and useful foods. For best potency preservation, we suggest adding the substance after heating it in liquid uses.
The natural ingredient gives the product a "clean label" look. You can give customers what they want—plant-based, non-GMO, and vegan-approved ingredients—without lowering the quality or effectiveness standards.
Versatile Applications Across Industries
Supplements for health: Part of "Vitamin P" combinations that are used to improve heart health. The ingredient helps keep capillaries strong and microcirculation healthy. High-pressure tableting and sealing don't break it down.
Functional Drinks: Used in sports recovery drinks and wellness drinks to fight oxidative stress caused by exercise. The extract stays clear in clear beverage systems and doesn't change during HTST pasteurization.
Cosmetics: Used as a natural tyrosinase inhibitor in anti-aging skin care products. In complicated oil-in-water emulsions, it works well and protects against UV rays and brightens the skin without using manufactured irritants.
Rigorous Quality Control Standards
Our framework for quality control is based on making sure chemicals are precise and safe. Comprehensive testing protocols that are in line with international pharmaceutical standards are used on every batch.
To make sure that the therapeutic doses are always the same across production runs, HPLC quantification confirms the levels of Eriocitrin and Hesperidin.
Verification of Purity: HPTLC testing finds any possible adulteration with manufactured flavonoids or cross-species pollution, making sure that the chemicals are really from lemons.
ICP-MS research proves heavy metal compliance (Pb <0.5ppm, Cd <0.1ppm) during safety testing. Using GC-MS/MS technology, multi-residue pesticide screening looks at more than 400 chemicals.
Controlling Microbes: The Total Plate Count stays below 1000 cfu/g, and E. coli and Salmonella are confirmed to be absent according to USP <2021> standards. According to USP/EP limits, residual ethanol levels must stay below 5000ppm.

Packaging & Delivery Options
Standard packaging includes 25 kg per fiber drum with double PE lining for moisture protection. Custom packaging solutions accommodate your specific handling and storage requirements.
We maintain sufficient inventory for rapid order fulfillment. Shipping options include express courier (FedEx), air freight for urgent orders, and sea freight for large-volume shipments.
Flexible order quantities support both R&D trials and commercial-scale production. Minimum order quantity starts at 1 kg, with sample supplies available for formulation testing before full-scale commitment.

FAQ
Q1: Why is Eriocitrin the best citrus flavonoids?
A: Eriocitrin is lemon-specific and water-soluble. Its metabolic activity is higher than orange or grapefruit flavonoids, making it more effective in aqueous preparations.
Q2: Can this ingredient handle high-temperature processing?
A: Our product can withstand 85°C temperatures for brief processing times. Post-boiling enhances potency in pasteurized liquids.
Q3: How do you handle tablet bitterness?
A: Advanced granulometry and moisture-barrier coatings are used. Our technologies isolate taste profiles without affecting dissolving rates, assuring pleasing sensory qualities in final goods.
Q4: What certifications back clean-label claims?
A: Only physical and aqueous-ethanol extraction are used. 100% plant-derived, Non-GMO confirmed, vegan-friendly product. All batches meet Halal and Kosher standards.
Q5: Shelf life-optimal storage requirements?
A: Keep in cold, dark double-PE-lined fiber drums below 25°C. Under these conditions, the substance has a 24-month shelf life and stable quality.
