Product Introduction
Grapefruit Flavonoid – Premium Citrus Extract from Kang Biotech
Kang Biotech brings 11 years of citrus processing expertise and 20,000,000 m² of controlled bitter orange orchards to extract high-purity Grapefruit Flavonoid. Our manufactured product is produced in a 33,000 m² certified facility with 9 contemporary lines and standardized Naringin content from 10% to 98% HPLC. Our ISO 9001, ISO 22000, HACCP, Halal, Kosher, and FAMI-QS batch-consistent nutraceutical, pharmaceutical, and functional food quality. Global partners in 40+ countries enjoy continual availability and fair pricing from crop to delivery with our integrated supply chain.
What Is Grapefruit Flavonoid?
Bioactive polyphenolic compounds including Naringin, Naringenin, Hesperidin, and Neohesperidin come from Citrus paradisi (grapefruit). These compounds' antioxidant, anti-inflammatory, and metabolic-regulating properties make them useful in drugs and nutraceuticals.
Excerpt addresses industry concerns. Medications for chronic disease minimize oxidative stress. Lipids are naturally stabilized by cardiovascular medicines. Current extraction procedures increase bioavailability and potency, ensuring therapeutic efficacy across batches.
Technical Specifications and Properties
For formulation stability, our product has exact chemical and physical properties. Flavanone skeleton with glycosidic connections makes up the light off-white to pale yellow crystalline powder.

The chemical is very stable at high temperatures up to 120°C for short periods of time, which means it can be used in processed uses. Significant radical scavenging activity is shown, and its structure stays intact at pH levels ranging from 3.0 to 7.0.
Core Advantages and Biological Activities
Naringin, the product's main ingredient, is good for your makeup in molecular and functional ways. Because it reduces inflammation, it may make blood flow better and lower its viscosity. The molecule has strong antioxidant and free radical-scavenging properties.
It's the main bitter part of grapefruit juice and is used in cooking and drinking. On its own, it makes the taste and sharpness better. Grapefruit and other citrus foods are very sour and last a long time.
We use high-tech extraction methods to lower the interactions between furanocoumarins and the CYP3A4 enzyme. This process change addresses the "Grapefruit Effect" in pharmacy settings, making it safer for more people to use new products.
Versatile Application Scenarios
Mix Grapefruit Flavonoid with three sectors that are doing well. AMPK pathways are changed in metabolic health products that help with weight loss and insulin sensitivity. People who work in retail and professional eating use this app.
For functional beverage stability, extract lowers lipid oxidation and extends shelf life without adding preservatives. With micronized forms, aqueous solutions are clearer, which solves tricky drinking matrix problems. Your clean-label goods meet the needs of customers who want natural materials.
Neohesperidin Dihydrochalcone and other sweets are made with it in medicinal intermediates. Chemical change methods are flexible. The structure of the chemical stays the same in industrial settings with high-shear processing and changing pH.
Rigorous Quality Control Framework
Our method for quality assurance puts legal compliance and B2B procurement factors at the top of the list. The main way for inspection is to use HPLC-DAD measurement to tell the difference between Naringin and Naringenin. ICH says that solvent waste should be less than 5000ppm after gas chromatography tests.
Lead (Pb <0.5ppm), Arsenic (As <0.5ppm), Mercury (Hg <0.1ppm), and Cadmium (Cd <0.1ppm) can all be found using ICP-MS for heavy metal screening. Testing for pesticide residues in more than 400 citrus chemicals must follow USP [561] guidelines.
With microbial control, the Total Plate Count stays below 1000 cfu/g, so there are no E. coli or Salmonella. These steps will make sure that your goods meet the strict requirements of the European, North American, Japanese, and South Korean markets.

Flexible Packaging and Logistics Solutions
Industrial packing is usually 25 kg per drum. Our inventory can handle both small purchases (1 kg) and large commercial shipments. Small packages can be sent quickly thru FedEx, but for large packages, you may need to use air or sea freight, based on your needs.
When it comes to purity, packing, and marking, OEM/ODM services meet specific needs. Regulatory requirements can be met with the help of technical paperwork and formulation consultation. Our transportation partners deliver quickly and safely no matter where you are.

FAQ
Q: How do you tackle 'Grapefruit Effect' drug interactions?
A: Our standardized extracts reduce furanocoumarins, the primary CYP3A4 enzyme inhibitors, lowering medication contraindications.
Q: What are the best potency-preserving storage conditions?
A: Keep in light-resistant containers at <25°C in a cool, dry atmosphere. Stability testing indicate a 24-36-month shelf life.
Q: Does cold water dissolve your product?
A: At 20°C, native Naringin is just 0.5g/L water-soluble. Our complexed or micronized versions boost liquid solubility.
Q: How does UV exposure affect the compound?
A: UV degrades color and lowers antioxidant activity. Packaging should be opaque for product integrity.
Q: Are your extraction processes green?
A: We utilize membrane filtration and green chemistry with aqueous or food-grade ethanol extraction. Carbon footprint and solvent waste decrease.
