How to Extract Lutein from Marigold
Lutein is a yellow plant pigment belonging to the xanthophyll family of carotenoids and widely present in marigold flowers. Lutein is an effective antioxidant that may be utilized in foods as a natural coloring pigment and functional feed ingredient.
Beyond its visual appeal, marigold extract holds a secret treasure. As a natural feed additive, lutein fits the trend of “antibiotic reduction and replacement” in the feed industry, especially in poultry and aquatic feed, where demand has grown significantly. Customers are more concerned about its cost-effectiveness, stability and traceability. Greenagribio needs to improve product competitiveness through process optimization (such as microencapsulation technology). This blog post tackles on what are the benefits and extraction methods of marigold flower extract for the well-being of our beloved animals.
What is Marigold Flower Extract?
Derived from the vibrant petals of the marigold flower (Tagetes species), marigold extract is renowned for its potent phytonutrients, including lutein and zeaxanthin. These compounds offer a spectrum of health benefits for animals, making marigold extract a valuable addition to their diet and care routines.

Extract Lutein from Marigold Manufacturer Process
- Raw Material Selection: We select fresh marigold flowers (Tagetes erecta) based on high lutein content.
- Flower Harvesting & Drying: Workers harvest the flowers at full bloom and dry them under controlled conditions (e.g., shade drying or low-temperature drying) to preserve lutein content.
- Grinding & Milling: We grind the dried flowers into a fine powder to increase the surface area for extraction.
- Pigment Extraction:
- Solvent Extraction: We treat the powder with organic solvents (e.g., hexane, ethanol, or acetone) to extract lutein and other carotenoids.
- Supercritical Fluid Extraction (SFE): Use CO2-based extraction under high pressure for a solvent-free, high-purity yield.
- Filtration & Concentration: We filter the extract to remove impurities and concentrate it by solvent evaporation or vacuum distillation.
- Saponification: We treat the crude extract with an alkaline solution (e.g., potassium hydroxide) to remove esterified forms and enhance bioavailability.
- Purification & Crystallization: The lutein-rich solution is purified using chromatography or crystallization techniques.
- Drying & Powder Formation: The purification process dries the lutein (e.g., spray drying) and converts it into a powder form for commercial applications.
- Quality Control & Packaging: A quality control team tests the final lutein extract for purity, potency, and contaminants before packaging.
- Detection: HPLC detection of lutein content to ensure compliance with feed additive standards.
