Lutein Ester Powder

Lutein Ester Powder is a carotenoid derived from marigold, which contains lutein, mainly in the esterified form. It has a different chemical and formulation profile from free lutein and is often considered for use in lipid-based and oil-compatible delivery systems.

Kingsci Lutein Ester Powder is made from Tagetes erecta marigold flowers and is standardized to a specific amount, making it suitable for use as an ingredient in B2B applications. Various assay specifications provide a choice of concentrations for the manufacturer, depending on the need for dosage, formulation, and processing conditions.

The powder format is ideal as an ingredient for the manufacturer producing functional food products, selected nutritional premixes, softgels, and dietary supplements.

Esterified Lutein Form

Lutein Ester is the form of lutein, with the option of free lutein, which is in ester form, as a single-ingredient source from which manufacturers choose their preferred form of carotenoid.

Marigold-Derived Source

Derived from Tagetes erecta marigold flowers, which are a common botanical source of lutein and lutein esters.

Standardized Assay

Several levels are available for the assays so that the manufacturer can choose an appropriate assay concentration based on their requirements for dosage, formulation, and manufacture.

Suitable for Lipid-Based Formulations

Lutein esters' compatibility with lipids is important for soft gel formulations and other oil-based products.

Documentation Support

Technical documentation such as COA, TDS, MSDS, and others can be provided to aid in ingredient evaluation and development of formulations, and also for purchasing.

Dietary Supplements

Ideal for manufacturers who make capsules, tablets, and other nutritional supplements that contain lutein.

Softgels & Oil-Based Formulations

It is lipid-compatible, indicating its suitability for softgels and certain oil-based delivery systems.

Nutritional Premixes

Can be used as part of the nutritional pre-mixes where a standard Lutein Ester ingredient is needed.

Functional Foods

Ideal for targeted functional food systems that are made with a carrot carotenoid source.

Customized Formulations

Kingsci can discuss the various technical requirements with the customer, such as the level of the assays, the type of carrier system, the packaging, and other technical requirements as per the formulation and production needs of the customer.

It is a matter of specification, since that will vary based on the final product dosage, product type, formulation makeup, and desired loading of ingredients.

Lower Assay Specifications

Useful for formulation flexibility and when the use of a lower concentration is desired.

Medium Assay Specifications

Balances active concentration/ handling of formulations for different applications of supplements.

Higher Assay Specifications

Ideal for producing a more concentrated lutein ester ingredient and reducing the amount of ingredients needed.

It is available in 5%, 10%, 20%, 40%, 60%, 80% (as per their production at the present time).

In formulating with Lutein Ester Powder, the manufacturer should take into account the intended assay that will be used, the dosage form in which it will be utilized, the compatibility of the oil phase, the processing temperature, and exposure to oxygen, moisture, and light. When applying for dry blending, particle size, bulk density, and the blending conditions should also be considered to aid uniform distribution of the finished blended product.

However, when using a lipid-based system (softgels), compatibility of the lutein ester ingredient with the oil phase should be established during the formulation process. Other factors such as antioxidant systems, processing systems, and packaging may also affect the stability of the carotenoids during storage.

It should be chosen depending on the specific level of Lutein in the end product and the dosage. Kingsci can provide the formulation technical documentation and samples for evaluation of formulation and selection of specification.

Marigold Raw Material

Lutein Esters are extracted from flowers of the plant Tagetes erecta.

Extraction & Processing

Controlled processing is utilized to get and concentrate the desired carotenoid fraction.

Standardization

The final product has the required amount of lutein ester.

HPLC Testing

The content of the active ingredient(s) is verified by HPLC analysis.

Finished Product Control

Finished batches are tested for physical, chemical, and microbiological quality parameters that are applicable.

Batch Documentation

For B2B product evaluation/purchasing, COA and relevant technical documentation are available.

What is Lutein Ester Powder?

Lutein Ester Powder is a powdered lutein ingredient that is mainly composed of lutein ester. It's typically made from marigold (Tagetes erecta) extract and is used in food supplements and functional formulations.

What is the source of Lutein Ester Powder?

The lutein esters in Lutein Ester Powder are usually extracted from marigold flowers (Tagetes erecta), which are naturally rich in lutein esters.

What specifications of Lutein Ester Powder are available?

Common specifications include 10%, 20%, 40%, 60%, and 80% lutein ester. Specifications may also be available, customarily, based upon formulation needs.

What is Lutein Ester Powder used for?

Depending on the dosage and the process of forming the product, Lutein Ester Powder can be used in dietary supplements, tablets, capsules, gummies, sachets, or nutritional premixes.

What is the difference between Lutein and Lutein Ester?

There are two types of carotenoids: lutein free and lutein ester, which is lutein attached to fatty acids. Selection is dependent on the formulation, stability, dosage form, and processing requirements desired.

Is Lutein Ester Powder suitable for softgels?

Yes. When the powder is properly incorporated into the system used to fill softgel capsules, it may be used in softgel formulations alongside Lutein Ester Powder. Lutein ester oil can be used when applying directly to oil-based formulations; it can be more convenient.
