Lemon Flavonoid

Premium Lemon Flavonoid Extract - Natural Citrus Bioactive from Kang Biotech

With the help of advanced water and ethanol extraction technologies, Kang Biotech makes high-purity Lemon Flavonoid extract from Citrus limon peel. We make standardized Eriodictyol that is 95% to 98% pure, as proven by HPLC. We have over 11 years of experience working with citrus ingredients and over 20,000,000 m² of controlled crops. There are 9 dedicated production lines in our 33,000 m² GMP-compliant building. These lines make sure that each batch is the same and that we follow all world regulations, such as ISO 22000, HACCP, Halal, Kosher, and FAMI-QS credentials. Conforming to USP standards, each batch goes through strict heavy metal testing (Pb <3ppm) and herbicide residue screening.

What Is Lemon Flavonoid and Why It Matters?

In the flavedo and albedo layers of Citrus limon, the product is a group of polyphenolic compounds. Hesperidin, Naringin, and Eriocitrin are the main flavanones in the profile, and they dissolve very easily in water.

That being said, this extract works well in water-based mixtures, unlike lipophilic polyphenols. To meet consumer demand for metabolic wellness ingredients and improve the quality of your products, look for clean-label alternatives to synthetic preservatives.

When compared to manufactured versions, Eriodictyol found naturally in lemon peel is more bioavailable. Being able to see where the ingredients come from makes it fit for useful foods and nutraceuticals.

Technical Specifications and Properties

During short-term processing, the extract is very stable at temperatures up to 120°C. Your formulations keep the integrity of the ingredients even when they are made in different ways.

Physical features include small particle size and hygroscopic qualities that need the right storing methods. The light yellow color works well with clear beverage systems and doesn't cause sedimentation.

Quality Control Standards You Can Trust

To meet your buying needs, our quality assurance follows guidelines for pharmaceuticals. The Eriocitrin-to-Hesperidin ratio is checked using HPLC fingerprinting, which stops cheap citrus sources from being mixed in.

ICP-MS heavy metal analysis makes sure that international limits are met. Lead stays below 3ppm and mercury stays below 0.1ppm in all runs of production. Full testing for pesticides meets USP [561] requirements for goods that are ready to be exported.

Headspace GC research shows that the only things left in the residual solvents are ethanol and water. Microbiological testing makes sure that high-care manufacturing environments don't have any E. coli, Salmonella, or Staphylococcus aureus.

For your regulatory applications, every proof of analysis gives you more information. We help your quality checks by giving you full traceability paperwork from the time the plants are grown until they are packed.

Versatile Applications Across Industries 

Functional Beverage Development: The extract remains stable in clear, acidified sports drinks at pH 2.5-4.5. Your RTD products work better because they don't contain sediment, which helps with healing after exercise by reducing oxidative stress.

Nutraceutical Formulations: High-potency pills usually have 500 mg amounts that are good for metabolic health. The flavanone profile works together to support good blood sugar levels and heart health in nutritional products.

Food Preservation Solutions: Lemon flavonoid is used in industry to make antioxidant films for products that are high in fats. This natural method stops lipid degradation, which makes the food last longer, without adding any artificial BHA or BHT.

Uses in cosmetics: The antioxidant properties help anti-aging formulas that need active ingredients that dissolve in water. Your personal care goods look better with a clean label if they have biological properties that have been proven to work.

FAQ

Q: Why is Eriocitrin the main quality indicator?

A: Eriocitrin differentiates lemon extracts from orange or grapefruit and improves beverage water solubility.

Q: How does the ingredient behave in acidic conditions?

A: The extract is stable at pH 2.5-4.5, making it appropriate for carbonated and still drinks.

Q: Is sensory profile affected?

A: Standard therapeutic doses may astringe. Bioactivity and organoleptic neutrality are maintained in debittered forms.

Q: What about California Prop 65 compliance?

A: Lead and cadmium levels in premium grades are strictly monitored to stay below Safe Harbor norms.

Q: What are ideal storage conditions?

A: To avoid flavanone glycoside photo-oxidation, store in double-PE bagged fiber drums below 25°C in dry circumstances away from UV radiation.
