概要

Dry micro-powder was made from kombu (Laminaria japonica), wakame (Undaria pinnatifida), and tosaka (Meristotheca papulosa) seaweeds. Its ability to prevent the increase of blood lipid level was examined in an experiment with rats. Each powder was divided into three parts: (A) high molecules with a molecular weight of more than 3 kd, (B) low molecules with a molecular weight of less than 3 kd, and (C) the remaining molecules. The two kinds of powder, (A) and (C), were mixed respectively into a high fat diet at a density of 1%, and powder (B) was mixed into a high fat diet at a density of 0.5%. The three kinds of powder were then given orally to the rats. The control group was given an unmixed high fat diet. The following significant differences were found: the blood neutral fat level of the control group (66.5 mg/dl, p<0.05), the kombu remainder group (28.2 mg/dl, p<0.05), the low molecule wakame group (42.8 mg/dl, p<0.05), and the tosaka remainder group (33.0 mg/dl, p<0.05), respectively. These results suggest the ability of seaweed powders to prevent clinincal hyperlipidemia.
