Product Characteristics & Formulation Advantages

Among the most practical benefits for B2B purchasers is the wide potency range. Whether you need low-dose 2% Lutein for food fortification or a concentrated 98% grade for premium softgel formulae, we can meet your exact specification without compromise.

There are three main types of formulation to match with different delivery systems:

  • Lutein Free – De-esterified version with lower molecular weight, optimised for direct absorption in human nutrition applications.
  • Lutein Esters – Chemically stable and economically effective for long term storage. Suitable for finished products that require long shelf life.
  • CWS Microencapsulated Beadlets - a starch or gelatine matrix cold water dispersible technology for fast dispersion in beverages and liquid supplements without cloudiness or sedimentation.

CWS format is also resistant to pasteurisation and pH changes making it suited for sports drinks and meal replacement formulations.

Application Scenarios

The key use case is Eye Health Nutraceuticals. Lutein and Zeaxanthin filter high energy blue light and promote macular health, hence this ingredient is often included in AREDS2-inspired vision support regimens, in tablet and softgel form.

The CWS grade is suitable for Functional Food & Beverage Fortification and disperses well in clear liquids and industrial processing such as high-shear mixing.

Another increasing category is animal nutrition. This extract is a natural pigment used in poultry feed that helps to give egg yolks and broiler skin their golden colour. It provides a clean-label alternative to the synthetic azo-dyes used in aquaculture and poultry production.

Quality Assurance and Safety

Before being sent, every batch of marigold extract powder bulk passes a multi-layer quality control process. Test protocols are as follows:

  • HPLC active ingredient assay to ensure correct trans-lutein and cis-lutein ratios and zeaxanthin concentration.
  • Solvent Residue Analysis for hexane, acetone and methanol - all under control below ICH limits.
  • Lead, Arsenic, Cadmium and Mercury ICP-MS Heavy Metal Screening
  • Microbiological Testing- Total Plate Count, Yeast/Mold, E. coli, Salmonella.
  • Stability Testing: Accelerated and long-term testing for the full 24-month shelf life, looking at oxidation and light sensitivity.

The plant has ISO 9001, KOSHER and HALAL certificates and uses GMP-based manufacturing management. The testing is carried out with HPLC and GC-MS analytical instruments to assure full accuracy and traceability.

Storage and Handling Guidelines

Carotenoids are sensitive to light, oxygen, and heat. To protect potency throughout the shelf life, follow these handling guidelines:

  • Store below 25°C in a cool, dry, well-ventilated space.
  • Keep away from direct sunlight and UV exposure.
  • Maintain sealed packaging to prevent oxidation and moisture absorption.
  • Avoid storage near strong-smelling materials due to potential odor absorption.
  • Once opened, reseal immediately and use within a reasonable timeframe.

Packaging is designed specifically for protective storage — options include vacuum composite film bags, aluminum foil nitrogen-filled bags, and light-resistant bottle packaging.

Packing and Delivery

Standard packing is 25 kg per drum using industrial-grade vacuum-sealed packaging to maintain ingredient integrity during international transit. Customized packaging formats are available including aluminum foil nitrogen-filled bags and light-resistant containers.

Shipping options include courier, air freight, and ocean freight. Ready stock is maintained to support prompt order fulfillment, with dispatch typically completed within 2–3 working days after order confirmation.

FAQ

Q1: What is the difference between Lutein Free and Lutein Ester?

A: Lutein Free is de-esterified for direct absorption and faster bioavailability. Lutein Esters are more stable and economical for longer shelf-life products.

Q2: How does the CWS grade dissolve in liquids?

A: The CWS microencapsulated format disperses evenly in water without causing cloudiness or sedimentation, making it suitable for clear beverages and liquid supplements.

Q3: Is the product Non-GMO and allergen-free?

A: Yes. The source flowers are non-GMO Tagetes erecta, and carriers such as maltodextrin used in powder forms are certified allergen-free.

Q4: How should temperature changes be managed during storage?

A: Keep the product below 25°C in vacuum-sealed, light-proof packaging. Heat accelerates isomerization and reduces potency, so stable cool storage is essential.

Q5: What customization options are available?

A: Lutein concentration from 2% to 98%, Zeaxanthin from 5% to 70%, multiple formulation types (Free/Ester/CWS), and customized packaging and labeling are all supported.

Q6: What documents are provided with each order?

A: A Certificate of Analysis (COA) with full test results is provided. Additional documentation to support regulatory compliance can be arranged upon request.
