[China, Global] The China Health Care Association and the Chinese Academy of Science came out with a guideline to advise consumers on how to identify genuine astaxanthin healthcare products in China. This guideline consists of 3 easy ways as described as follow:
1. Identify the product’s label and the China Food and Drug Administration’s logo.
Since September 2012, China’s FDA restricts the use of all forms of tablet, capsule and soft gel as food. Under the new law, all forms of tablet, capsule and soft gel must be sold as drug or health supplement, which clinical trials and extensive clinical testings are required.
Besides, the content, such as the raw ingredients and the bioactive components of a particular health supplement, must be written clearly on the product’s label. All astaxanthin products without FDA’s approval logo or label of content description are not the products approved by the FDA, and consumers are advised not to purchase such products.
Consumers are also advised to visit China’s FDA official website to find out a list of astaxanthin products which have been registered and approved. Consumers are warned that all the FDA approved astaxanthin healthcare products sold in China are produced locally in China. Up to date, the China’s FDA has not approved any imported astaxanthin healthcare product to be sold in China’s market.
2. Test the content of astaxanthin soft gel with water or oil
Astaxanthin is a carotenoid, which exist in liquid form of oil. Capsules that consist of powder in red color are probably the algae biomass (in most case, Haematococcus pluvialis dried powder). Astaxanthin is lipid soluble, which means it is readily dissolve in oil. Cut a soft gel and release its content into a bottle of cooking oil, the cooking oil’s color will turn red after gentle mixing. Fake astaxanthin, which may be in the form of water in red color, will not mix with cooking oil.
On the other hand, we may also test the astaxanthin with water. Cut a soft gel and release the content into a glass of water, real astaxanthin will spread evenly on the surface of water just like an oil drop on the surface of water. It does not diffuse well into the water.
3. Expose the content of astaxanthin soft gel to light
Cut a astaxanthin soft gel and spread its content on a piece of white paper. Expose paper to light.
Astaxanthin is very sensitive to light, and will undergo photodegradation and oxidation within 48 hours, or even shorter. A normal red dye or food grade red dye is resilient to light. Some astaxanthin product, which is not at its absolute 100% purity, may consist of trace amount of chlorophyll, which will be revealed when the color of astaxanthin faded. This represents the quality of astaxanthin product. If the astaxanthin is a synthetic one, there will be no chlorophyll residue in it.
