Complex polysaccharides derived from torula yeast

Mitsubishi Corporation Life Sciences has succeeded in producing a new complex polysaccharide from yeast cell walls that had been discarded after fermentation.

Torula yeast (Cyberlindnera jadinii) is a yeast widely used in the production of seasonings and other products that impart flavour and richness through fermentation, but many of the yeast cells produced in the manufacturing process are not utilized and are discarded.

We isolated complex polysaccharides from the cell walls of this discarded yeast cell by alkaline washing/enzymatic treatment. The polysaccharide complex is a white to light yellow powder, containing about 40% β1,3-1,6 glucan, which is well known for its cell activating action, and about 30% mannan and other polysaccharides.1

Although originated from yeast with sufficient food history, safety testing results AMES test, in vitro skin irritation test, in vitro eye irritation test, human patch test, and RIPT (human cumulative irritation) test were conducted, all of which showed negative results. When the effects on the skin were evaluated, high moisturizing and texture (kime) improvement effects were observed
