Raw Material Processing and High-Efficiency Extraction
High-quality turmeric rhizomes are carefully selected, washed, dried, and pulverized into a uniform powder of 60-80 mesh. The turmeric powder is added to an extraction tank, and a 70-85% food-grade acetone aqueous solution is added as a solvent, strictly adhering to a liquid-to-solid ratio of 1:8-10. Enhanced extraction is performed under ultrasonic assistance, repeated three times to maximize the dissolution of curcuminoids. The extracts are combined, precisely filtered, and then introduced into a vacuum concentration system. Most of the acetone solvent is recovered under low-temperature conditions (recovery rate >95%), yielding a concentrated, brownish-red, oily crude curcumin extract. The recovered solvent can be purified and recycled.
Multi-Stage Liquid-Liquid Extraction Refining
This is the core refining step. A specific ratio of extractant system (petroleum ether:water:ethyl acetate) is added to the crude extract, and multi-stage countercurrent liquid-liquid extraction is performed in specialized extraction equipment. This step selectively and efficiently removes water-soluble impurities (such as sugars and salts) and fat-soluble impurities (such as turmeric oil and waxes), thus initially enriching and purifying curcumin. The curcumin solution after extraction and separation is freeze-dried to obtain refined curcumin powder with extremely low moisture content, preparing it for subsequent crystallization steps.
Fractional Crystallization and Product Standardization
The refined curcumin powder is dissolved in hot ethanol. Purified water is slowly added dropwise while precisely controlling the temperature and stirring to induce crystal precipitation. This process yields orange-yellow needle-shaped primary crystals. After centrifugation to separate the mother liquor, HPLC analysis shows its purity can reach over 88%. To obtain a higher-specification product (such as 95% standard), the primary crystals are dissolved again in hot ethanol, and the ethanol-water crystallization process is strictly repeated. The crystals precipitated this time are orange-red needle-shaped crystals with superior morphology and purity. HPLC analysis shows that the purity of the recrystallized product can reach over 95%.
The collected high-purity crystals are freeze-dried to remove residual solvent and moisture. The resulting crystals are crushed and sieved (e.g., made into 20-60 mesh particles or finer powder), and finally the content and quality of the Curcumin Extract Powder are verified by HPLC to ensure compliance with target standards such as CP/USP/EP, and standardized packaging is carried out according to customer requirements.
Curcumin Extract Powder benefits
Curcumin Extract Powder for dogs
KINTAIBIO®'s premium Curcumin Extract Powder, based on scientifically proven antioxidant and anti-inflammatory properties, is increasingly used to prevent symptoms of various canine diseases. Authoritative research shows that adding appropriate amounts of curcumin to dog food effectively improves feed stability-significantly reducing protein oxidation and lipid peroxidation levels during storage, enhancing total antioxidant capacity, and thus better preserving the freshness and nutrition of the food.

For dogs, the health-promoting effects of ingesting curcumin-containing feed are mainly manifested in two aspects: first, it enhances the body's antioxidant defense system, increasing the activity of various antioxidant enzymes in serum and total antioxidant capacity, helping to neutralize excess reactive oxygen species and protect cells from oxidative damage; second, it exhibits a clear anti-inflammatory support effect, with studies showing it can regulate the number of specific immune cells (such as lymphocytes), helping to alleviate inflammatory states in the body. These effects collectively contribute to supporting the overall health of animals, showing particular potential in maintaining immune balance and cell protection.
Curcumin Extract Powder for liver
Curcumin Extract Powder has a strong scientific basis for supporting liver health. Studies have confirmed that oxidative stress is a core mechanism leading to liver damage caused by various factors, including alcohol and metabolic disorders, and can drive the progression of disease from fatty liver to hepatitis, fibrosis, and even cirrhosis. As a natural polyphenol, curcumin's unique phenolic hydroxyl groups and β-diketone structure enable it to directly neutralize reactive oxygen species (ROS), exerting a powerful antioxidant effect.

More importantly, it can enhance the body's own defense capabilities by regulating key signaling pathways such as Nrf2, thereby increasing the activity of antioxidant enzymes in the body, such as SOD, CAT, and GSH. Simultaneously, curcumin can inhibit the activation of pro-inflammatory factors and hepatic stellate cells, demonstrating anti-inflammatory and anti-fibrotic potential, helping to alleviate chronic low-grade inflammation and slow the progression of liver disease.
Curcumin Extract Powder for eyes
Due to its multiple bioactivities, including anti-inflammatory, antioxidant, and neuroprotective properties, Curcumin Extract Powder demonstrates significant potential in supporting eye health. Studies have shown that curcumin can effectively reduce oxidative stress, inhibit abnormal angiogenesis and apoptosis by regulating key signaling pathways such as NF-κB, thus helping to address various challenges from the anterior to posterior segments of the eye.

For anterior segment issues such as dry eye and keratitis, its anti-inflammatory properties can help alleviate discomfort; while for posterior segment diseases such as diabetic retinopathy and age-related macular degeneration, its neuroprotective and anti-angiogenic effects provide positive support. Although standardized curcumin itself faces challenges such as low water solubility and limited absorption, modern formulation technologies are effectively improving its bioavailability and targeting. Therefore, our high-quality Curcumin Extract Powder raw material can serve as a core ingredient for developing innovative eye health products, providing a raw material option for supporting long-term eye health through nutritional interventions.

KINTAIBIO®'s Curcumin Extract Powder, with its scientifically proven multiple bioactivities, has become a highly sought-after core ingredient in modern dietary supplement formulations.
The core value of Curcumin Extract lies in its ability to effectively neutralize free radicals and reduce oxidative stress and chronic inflammation-the common physiological basis of many chronic health problems. Therefore, curcumin is widely used to support joint comfort, post-exercise recovery, liver health, metabolic balance, and overall immune regulation. In specific areas, such as supplements for eye health and cognitive function, its neuroprotective properties also show great potential.
Curcumin Extract Powder side effects And dosage
turmeric Curcumin root Extract Powder side effects
Current scientific evidence and authoritative assessments indicate that the use of Curcumin Extract Powder at recommended doses is safe. The Acceptable Daily Intake (ADI) of curcumin established by the World Health Organization (WHO) and the Joint FAO/WHO Expert Committee on Food Additives (JECFA) is 3 mg/kg body weight/day. In short-term clinical studies in adults, daily intakes up to 8 grams for 2 months are generally considered well-tolerated, with no serious toxicities observed.
However, at high doses (usually exceeding 1 gram daily), a small number of individuals may experience mild gastrointestinal discomfort, such as stomach upset, nausea, or diarrhea. Therefore, we recommend that consumers refer to the recommended dosage on the product label or follow professional advice when using it as a dietary supplement, and consult a medical professional before long-term high-dose use.
how much Curcumin Extract Powder per day?
The safe and effective dosage of curcumin varies depending on its intended use and the individual.For human food and dietary supplements: Follow the general safety guideline of 3 mg/kg body weight/day. For example, the recommended daily intake for a 60 kg adult is no more than 180 mg. As a food coloring agent (E 100), its contribution to a typical diet is usually well below this limit.
For animal nutrition: The European Food Safety Authority (EFSA) has established specific safe levels for the use of curcumin extract as a sensory additive. For example, the recommended maximum addition of curcumin extract in complete feed for all animals is 15 mg/kg of feed.
