Xi'an Le-Nutra Ingredients Inc specializes in manufacturing high-purity Lutein Powder Bulk derived from premium marigold flower petals. With 14+ years of botanical extraction expertise, our 60,000㎡ GMP-certified facility delivers 3,000 tons annually of 10% lutein powder tested by HPLC. Our enterprise-grade product maintains strict oxidation control through nitrogen-filled packaging, achieves residual solvent levels below 50 ppm hexane, and meets USP/EP standards with heavy metal limits of Pb <0.5 ppm and total ash ≤5.0%. Backed by comprehensive COA documentation and 98% on-time delivery performance, we provide stable supply solutions for nutraceutical manufacturers, functional food developers, and cosmetic formulators worldwide.

What Makes Our Lutein Powder Bulk Superior for Commercial Applications?

Our product originates from manually sorted marigold petals cultivated in pesticide-controlled farms. The deep orange-yellow fine powder exhibits excellent flowability with 90% particles passing through 80 mesh, ensuring uniform blending in capsule and tablet production.

Advanced HPLC testing confirms 10% trans-lutein content, maintaining the clinically relevant 5:1 lutein-to-zeaxanthin ratio proven effective in AREDS2 studies. Loss on drying remains below 5.0% to prevent microbial proliferation during storage.

Our extraction process minimizes benzo(a)pyrene levels to <10 ppb, significantly below EU thresholds. Microbiological testing guarantees TPC ≤250 CFU/g with negative results for E.coli and Salmonella, meeting international pharmaceutical-grade requirements for dietary supplement manufacturing.

Technical Specifications and Quality Parameters

Industrial Applications Across Multiple Sectors

This product is a core ingredient in eye care supplement formulations for digital device users who suffer from screen-induced eye strain. Our powder is used by soft capsule producers in everyday vision support goods for both office workers and gamers.

Functional beverage producers capitalise on the natural pigment qualities to give antioxidant benefits while enhancing colour. The powder is readily included into tablet compression methods for multivitamin formulations comprising eye health complexes.

Our substance is used in anti-aging skin care products by cosmetic formulators due to its ability to neutralise free radicals. It can be formulated into emulsions, serums and lipstick formulas with natural yellow-orange tones due to its oil-soluble nature.

Therefore, more and more pet nutrition producers are adding lutein to premium dog and cat meals that support retinal health in ageing animals. The stable powder form can endure the extrusion processing temperatures characteristic of kibble manufacture.

Core Functional Benefits for Product Development

Lutein concentrates in the macula, the central part of the retina, acting as a protective filter to block out damaging blue light wavelengths from digital screens. This process decreases oxidative stress on the photoreceptor cells after long-term exposure to the device.

The chemical helps relieve the usual symptoms of computer vision syndrome, including dry eyes, discomfort and visual fatigue. Clinical studies have shown its importance in preserving macular pigment optical density, associated with better contrast sensitivity.

Lutein Powder Bulk is a powerful anti-oxidant that is able to quench reactive oxygen species created from UV radiation and metabolic processes. This effect slows down the degenerative changes in ocular tissues related to ageing.

Long-term supplementation may reduce risk factors for age-related macular degeneration. The carotenoid enhances general visual comfort during tasks that demand prolonged focus and accommodation.

Colouring applications in nature Its colour remains uniform in many pH ranges . It can be used as a substitute for synthetic dyes in food and cosmetics colour matching . The GRAS status eases regulatory acceptance in various jurisdictions.

Manufacturing Excellence and Compliance Standards

We operate six multipurpose production lines, all of which are strictly GMP controlled and third-party audited. ISO certification guarantees consistent process controls from raw material intake to finished packaging.

Advanced HPLC technology is employed to separate trans-lutein from less bioavailable cis-isomers, ensuring the stated 10% active concentration. Residual solvent testing reveals hexane levels are below safety limits stipulated by pharmaceutical compendia.

Each production batch is screened for heavy metals using ICP-MS technology and accurately quantified against USP limits. Microbiological testing is performed using FDA BAM techniques for detection and enumeration of pathogens.

Every shipment comes with a Certificate of Analysis reporting on 15+ quality factors and batch traceability codes. 30+ days safety stock maintained to smoothen seasonal raw material volatility & assure ongoing supply.

Kosher and FDA registration status widens market reach for clients targeting different consumer groups. Our quality system facilitates the implementation of HACCP for food grade applications.

Smart Storage and Handling Guidelines

Sealed containers should be stored in a cold dry warehouse below 25°C and relative humidity less than 60%. Keep in opaque containers and store in the dark. Carotenoids degrade more quickly when exposed to light.

Exposure to oxygen starts oxidation events that diminish the effectiveness of lutein over time. Fibre Drums: Double polyethylene liners with nitrogen flush provide an inert atmosphere to maintain product integrity for the whole 24-month shelf life.

Open containers shortly before use and minimise headspace. Reseal immediately after use. Move unwanted pieces to smaller containers to minimise air exposure during consumption.

Store away from heat sources, steam lines, or direct sunshine when warehousing and producing. Temperature changes might lead to condensation of moisture in the packing which may affect microbiological stability.

Rotate inventory on a first-in-first-out basis, based on manufacturing date printed on the labels of the drums. Check it periodically to see if there is any discolouration or clumping which would mean it is going bad.

Flexible Packaging and Global Delivery Options

The standard packaging is 25 kg fibre drums, light-proof, with food-grade double polyethylene bag liners to prevent contamination and moisture penetration. Other packaging designs are available for special handling requirements or order quantities.

We offer a variety of delivery options including EXW, FOB, CFR, CIF, DAP and DDP, depending on your logistics requirements and cost structures. We have formed partnerships with foreign freight forwarders, which ensures affordable shipping costs.

Payment flexibility 100% T/T, confirmed transactions with Alibaba Trade Assurance and Western Union for smaller sample orders. Minimum order quantities are adjustable dependent on customisation requirements and delivery timelines.

Express courier services deliver small samples within 5-7 business days to most international destinations. Bulk ocean freight shipments take 25 to 30 days for North American ports and 20 to 25 days for European destinations after order confirmation.
