All our ingredients are stable (export quality).
We made our Lutein CWS 5% powder from top-notch marigold flowers by using ultra-modern microencapsulation technology, and we are able to provide a great powder dispersibility, improved stabilised, and perfect compatibility with functional food recipes. Besides the preferred 5% specification, we also provide our customers with 10% or 20% HPLC lutein that can meet your different needs for dietary supplements and health products.

Lutein naturally appears as a carotenoid in many green, leafy veggies as well as many types of fruit. It also exists in large quantities in marigolds (Tagetes erecta). Lutein is considered one of the most essential macular pigments found in the human eye, and because of this it's been receiving much more attention due to its role in preserving vision and promoting healthy aging.
Compared to standard types of lutein extractions basically, Lutein CWS 5% powder takes the form of modern microencapsulation. The microencapsulated technology used to protect the active and food-grade coating significantly increases the ability of the lutein to withstand heat, oxygen, and light, as well as improve its dispersibility in water. which makes it much easier to introduce lutein powder into functional beverage applications, dairy products, gummy candies, powdered drink mixes, and other functional food systems.
The result is an ingredient with excellent stability that will allow manufacturers to process more effectively without negatively impacting the natural health benefits of lutein.

Lutein extracted from marigold flowers cultivated under strictly controlled agricultural conditions. Marigolds are among the richest sources of natural lutein found in nature. Due to this, marigold is preferred as a source raw material for production of high-quality dietary ingredients.
The process of manufacture is based on purity and sustainability, resulting in a naturally produced product that does not contain artificial colors and or synthetic chemicals.
Each batch of product undergoes stringent quality management and maintains its quality and strength, ensuring the constant presence of the optimum quality and strength, along with the high purity and the performance of the product.

Good stability and dispersibility make Lutein CWS 5% powder very popular with the nutrition products markets out there today.
Suitable for capsules, tablets, sachets and gummies as well as powdered nutritional supplement forms of products that promote eye health and general health/ wellness.
One of the fastest growing trends for lutein is the eye health gummie category where Lutein CWS 5% powder is being formulated into a gummie format to provide a fun, easy-to-use supplementation option for consumers.

Manufacturers are turning to Lutein CWS powder (Natural Yellow Colorant) more and more as a way of coloring dairy foods naturally while also providing a nutritional benefit through yogurt, milk beverages and dairy based nutritional products.
This product can be dispersed very easily and incorporated smoothly into finished powdered drink formulations (such as instant beverages), as well as liquid-based functional beverage types.

Traditional lutein is highly susceptible to heat and oxidation when it comes to producing food products.
We use microencapsulation technology to make sure that we protect the lutein molecule when we do all of the manufacturers typical procedures, including mixing, drying, transporting, and storing.
The improved lutein 5% CWS powder heat stability in food processing allows manufacturers to produce the same high-quality products with less waste.
That means that manufacturing processes are more efficient, product appearance is better, and the ability to create new formulas is increased.
