Cacao bean which is the material of chocolate and cocoa drink, is rich in d
ietary fiber. We prepared Klason lignins from defatted cacao mass and defat
ted cacao bean's husk. Cacao mass which is ground from roasted cacao cotyle
don, is the material of chocolate and cacao bean's husk in waste material i
n chocolate industry. The effects of these Klason lignins and defatted caca
o bean's husk on blood pressure and lipids metabolism were studied in spont
aneously hypertensive rats (SHR). Male SHR were kept on a semipurified diet
containing 1% NaCl and 3% test samples for 19 days. The mean of blood pres
sure in the control group increased, but the means of blood pressure in the
test sample's groups were significantly lower than that in the control gro
up. The serum total cholesterol levels in the test groups were significantl
y lower than that on the control group, too. The means of serum HDL-cholest
trol weren't changed significantly, the changes of serum total cholesterol
reflected the changes of serum (LDL + VLDL)-cholesterol. There were no sign
ificantly differences in serum triacylglyceride and phospholipid, and liver
lipids, These results suggest that lignins from cacao bean's husk may supp
ress the increment of blood pressure and serum levels of total cholesterol
as same as lignins from cacao mass. Also cacao bean's husk may be useful as
a new source of dietary fiber.
