In Japan, seaweed has been used as food since prehistoric times. Recently, because of the increasing health consciousness regarding food, polysaccharides, which are components of seaweed, have been gaining attention. Mozuku (a type of brown algae) contains large amounts of fucoidan, which is a polysaccharide mainly composed of fucose, and contains uronic acid and a small amount of xylose. Additionally, fucose is partially bound to sulfate groups, which gives it its viscous properties.
At Yakult, we focused on and advanced research and development of fucoidan derived from Okinawan mozuku seaweed. As a result, we have confirmed that the main component fucoidan obtained through our unique manufacturing method has excellent physiological effects, such as improving non-specific stomach complaints and reducing H. pylori bacteria, which is known to be deeply involved in gastric diseases.
Yakult Fucoidan uniformly distributes the mineral components within the fucoidan, allowing for consistent effects on the stomach. Furthermore, by standardizing the molecular weight size (50,000–100,000), viscosity is reduced, making it easier to handle as a raw material.
Yakult Fucoidan is available for use as a health-oriented food ingredient.
When 10 patients with nonspecific complaints consumed fucoidan-containing tea for 14 days, their gastric symptoms showed clear improvement compared to before consumption. This effect is believed to be due to the promotion of gastric motility.
When 11 H. pylori-positive subjects consumed fucoidan-containing tea (100 mg/day) for 10 days, their H. pylori bacterial count decreased by approximately half. The consumption of fucoidan is expected to have a reducing effect on H. pylori bacteria.
H. pylori bacteria adhere to sugars (such as fucose) on the surface of gastric epithelial cells. Fucoidan, which contains fucose as a component, can competitively inhibit H. pylori's adhesion to gastric epithelial cells. (Demonstrated at in vitro level).
Fucoidan extracted from Okinawan Mozuku shows wide variations in anti-ulcer activity.
Through our unique manufacturing method, ion exchange treatment is applied to convert fucoidan's sulfate ester groups into free acid and alkali metal salt forms.
Successfully reduced variations in anti-ulcer activity.
