Goji fruit dry extracts is widely used for food supplements worldwide
Goji, Goji berry or Wolfberry, is the fruit of Lycium barbarum or Lycium chinense. Since the early 21st century, the dried fruit has been marked as a health food. Goji fruit dry extracts becomes more popular.
Some research claimed the Polysaccharide in the fruits is the main ingredients that have biological activities and beneficial health.
So dietary supplement manufacturers seek to bring Goji fruit dry extracts with specified assay of Polysaccharide into their formulations to enhance the product performance.
There are many suppliers in the market that claim to able providing such Goji fruit extracts with a very attractive price at usd10-15/kg. Some Customs data shows hundreds of tons of such products exported to worldwide users from China every year.
Is the Goji fruit dry extracts you using the real NATURAL SOURCED?
Let’s check one of the popular specifications of such an extracts for information like:
Name: Goji fruit dry extract
Assay: Polysaccharide 50% Min. by UV method.
Botanical source: Lycium barbarum.
Now comes the question, is the above specification with 50% Polysaccharides the real product?
The answer is definitely NO!
So, what’s inside?
Well, we have some widely accepted scientific basics of Natural Goji fruits:
The natural Polysaccharide in the dry fruits is only around 3% (w/w), the current market price for the dried fruits is at usd 5/kg;
So, in order to make one KG of the dry extracts with a 50% level of Polysaccharide, can you image how many quantities of dried fruits will take in to the process? The native D/E ratio will higher than 10:1!
According the current published articles, if we insist to take the natural Polysaccharides from the Goji fruits, the highest level people can make is only 30%, without advanced techniques, assay higher than 30% is impossible.
What kind of Chemicals is added to the Goji fruit dry extract?
The answer is Maltodextrin!
So, how can suppliers get the 50% of Goji Polysaccharides with such a low price to sell in the market?
The answer is: Maltodextrin.
Maltodextrin is an ingredient that also is classified to Polysaccharides.
Suppliers add Maltodextrin into the Goji fruit dry extracts to substitute the Natural Polysaccharides in order the decrease the price.
Still we will take the above specification of Goji dry extracts for reference:
If 50% Polysaccharides with price usd10-15/kg, how much Maltodextrin will be added?
The answer is 50%, yes, it is shocking, right?!
Suppliers take some powdered Goji fruit to mix with Maltodextrin. The current testing method like UV cannot tell Maltodextrin from the natural Goji sourced Polysaccharide. Such an artificial product will have a characteristic Goji odour and taste due to the grinded Goji fruits were added. But, in fact, the product is a faked botanical extracts.
Does supplier has margins to sell the “artificial Goji fruit dry extracts” with such a low price around usd10-15/kg? The answer is YES!!
The price of Maltodextrin is only around 0.6usd/kg, so you can image how much profit gap will be obtained if suppliers sell the artificial Goji fruit dry extracts with price like usd10-15/kg.
Let’s say NO to adulteration botanicals from now on!
