Chinese Wolfberry - Extractpowders
Processing
Generally dried gojiberries are used to make a concentrated Gojiberry extract powder with the desired polysaccharide content.The intended Lycium Barbarum Polysaccharides (LBP) are water soluble, a sterile process environment is necessary the extract this component from the berries.
 |
A highly controlled processing method ensures that the dry gojiberries are processed into extract powders according approved standard processes. |
After extraction the liquid extract is dried into powder.
This extraction process can result in various extract powders. The most common one is a water soluble Wolfberry extract powder with 10% Polysaccharides (LBP).
In order to reach considerable higher LBP-contents then this 10%, prior to drying, molecular separation techniques are used to separate the smaller molecules (mainly mono- and disaccharides) from the liquid extract.
Depending on the degree in which these smaller molecules are removed, the higher the actual content of LBP in the extract powder will be.
In this way, practically the highest content of LBP that can be reached is approximately 50% polysaccharides.
For special applications sometimes juice is pressed from the fresh berries. This juice has other features then the regular extract powder and also has a more pleasant taste.

Properties
Regular Gojiberry extract powders dissolve well in water.The color of most Gojiberry extract powders is brown to red-brownish. As the level of polysaccharides rises, in general the color of the powder will become darker.
 |
Concentrated wolfberry extract powder has a brown to redbrown color. |
The taste of Gojiberry extract powder is quite typical and slightly sweetish. Lower concentrated extract powders usually possess more of the characteristic taste of the berries then high concentrated extract powders.
A possible practical disadvantage from Gojiberry extract powders is that they are quite hygroscopic: they easy attract moisture from the air. When not preserved the right way the powder is at a high risk of clotting together. Keeping it dry in closed packaging is therefore vital.
Additives
To reduce the costs of the extract powder, adding filler is an option. The cheapest filler is ground rice flour.For other (process technological) reasons also other possible additives like: dicalciumphosphate, maltodextrin, silicon dioxide, magnesium stearate or glucose powder are used. Of course other additives, carriers or fillers are possible too.
Another benefit of adding filler to the extract powder is that it can drastically decrease the hygroscopic nature of the product.
Dosage
For optimal therapeutic results of Gojiberry extract powders it is advised to use 150-250 mg pure Lycium Barbarum Polysaccharides (LBP) daily.There is no dangerous (damaging) maximum daily dose, but 25 mg of pure Lycium Barbarum Polysaccharides (LBP) daily should be considered as a minimal dose. If you take less than this dosage a day it will most likely not contribute anything.
When mixed with other medicinal herbs, a lower dose of Gojiberry extract powder might be sufficient too.
