Generally dried goji berries are used to make a concentrated Goji berry 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.
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 more details, please kindly consult NS-Bio. |
