Beta-carotene is a natural fat-soluble carotenoid that can be extracted from plant sources (such as carrots, pumpkins, bell peppers, and microalgae like Dunaliella salina and Haematococcus pluvialis) through extraction, purification, and crystallization processes. It can also be produced through microbial fermentation or chemical synthesis. Its core biological activity is provitamin A activity, which can be converted into vitamin A in the human body. It also has significant antioxidant capacity and is a widely used functional raw material in the food, health product, and daily chemical industries.

Lutein is a naturally occurring carotenoid commonly extracted from marigold flowers (Tagetes erecta). It is widely used in eye-health, healthy-aging, children’s nutrition and beauty-from-within formulations.
Commercial lutein ingredients may be standardized as free lutein or lutein esters, depending on the extraction and processing method.
Lutein can be supplied in several concentrations and delivery formats, including:
Lutein powder
Microencapsulated lutein powder
Water-dispersible lutein beadlets
Lutein granules
Lutein oil suspension
Lutein combined with zeaxanthin
The appropriate format depends on the target dosage form, required stability, dispersibility and processing conditions.
Lutein is suitable for:
Eye-health capsules and tablets
Gummies
Sachets and stick packs
Functional beverage powders
Children’s nutrition products
Multivitamin premixes
Healthy-aging supplements
Beauty-from-within formulas
Microencapsulated or beadlet formats are generally preferred for dry products because they offer better flowability, oxidation protection and dosage-form compatibility.
Lutein is sensitive to oxygen, light and heat. Microencapsulation surrounds the lutein with a protective wall matrix, helping improve stability during processing and storage.
Key quality parameters may include:
Lutein assay
Zeaxanthin content
Moisture
Particle size
Dispersibility
Residual solvents
Heavy metals
Microbiological limits
Light-resistant, oxygen-barrier packaging and controlled storage conditions are recommended.
Marigold-derived lutein is plant-based and can be suitable for vegan formulations. Depending on the carrier system, it can also support allergen-conscious and clean-label positioning.
For vegan products, plant-based wall materials such as modified starch, gum arabic or other suitable carbohydrates may be selected instead of gelatin or dairy-derived carriers.
Final claims should be confirmed against the product specification, allergen statement and manufacturing-site controls.
