Abstract
Disclosed are an immune-boosting food composition containing a green tea hydrolysate as an active component, and a method for preparing the same.
Claims5
A method for boosting immune function comprising:
- administering to a subject in need thereof, a food composition containing a crude polysaccharide fraction of green tea which is prepared by treating green tea powder with an enzyme,
- wherein the green tea powder is made from mature green tea leaves and the enzyme is pectinase and does not comprise cellulase;
- centrifuging the resulting enzymatic hydrolysates to remove residues;
- adding ethanol to the resulting extract, followed by stirring to precipitate polysaccharide;
- and
- centrifuging the precipitated polysaccharide to obtain a crude polysaccharide fraction.
