Product Name | Character | Specification | Function |
Water-soluble lutein | Deep yellow powder | 5%(W/W), 10% (W/W) | Anti-oxidant; Eye protection |
Description and solubility
Free-flowing, dark-orange powder. The product can be scattered into stirred cold water, to obtain a stable yellow-to-orange dispersion.
Composition
Glucose syrup, modified starch, lutein, DL- alpha –tocopherol, sodium ascorbate, and ascorbyl palmitate.
Specifications
5%, 10% (W/W)
Storage/Handling
The product is sensitive to oxygen, light, heat, and moisture. It should therefore be stored in the tightly sealed, lightproof packaging in a cool place. Once opened, it is recommended to use the remaining contents as quickly as possible.
Features
The product shows excellent dispersibility in cold water.
Application
Used in effervescent tablets, beverages, and other food and dietary supplement products.
Physiological importance
Lutein is—like other carotenoids—a powerful antioxidant and helps to prevent oxidative stress. Lutein does not have provitamin A activity.
Eye health
Lutein is the major carotenoid found in the human eye and plays an important role in eye health.It selectively accumulates in eye tissues and is, along with zeaxanthin and some metabolites, the only carotenoid found in lens and retina of the human eye.
The highest concentration of lutein in the human body is found in the macular region of the retina in the back of the human eye, particularly in the center (fovea, “yellow spot”). Lutein, zeaxanthin, and mesozeaxanthin— a lutein metabolite— comprise the so-called “macular pigment.” The density of macular pigment is considered a marker for macular health. It strongly correlates with lutein intake and is inversely related to the risk of age-related eye diseases.
As a natural filter of blue light and antioxidant, lutein may protect eye tissues such as the retina and lens from light damage as well as from other sources of oxidative stress (“free radicals”) resulting from exposure to cigarette smoke, pollution, and other environmental hazards.
Heart disease and cancer
Like other carotenoids, lutein may also have a number of other health benefits preventing chronic diseases such as heart disease and some cancers (such as lung, breast, and colon cancer). This has been suggested by a number of epidemiological and experimental studies, which associated high lutein intake with a decreased risk of chronicdisease.
NNET: Novel Nano Emulsion Technique
A nano-emulsion preparation technique with the aid of analytical techniques and computer design, selects the method of self-emulsifying or physical homogeneous to produce water-soluble preparation of insoluble compounds as well as protect and increase its bioactivity in oral route.
NNET with self-emulsification
