The invention relates to production of a yeast strain with increased mannan oligosaccharides, amino acids, and complex carbohydrates. The invention further relates to the process to propagate and ferment such yeast. The invention further relates to methods of use of the yeast as a feed additive for animals and a food product for humans.

Provided is a taste-improving agent that suppresses the unpleasant taste of potassium, such as harshness, irritativeness, and bitterness without reducing the salty taste of a potassium-containing food or drink. The taste-improving agent for a potassium-containing food or drink comprises a lactic acid-fermented yeast extract that is obtainable by fermenting a yeast extract with a lactic acid bacterium and contains 7.5 (w/w) % or more of lactic acid relative to the solid content of the yeast extract.

The present invention relates to a method for preparing a trehalose-rich yeast extract, said method comprising a step in which yeast cells are enzymatically disrupted by use of one or more proteases. The present invention further relates to a novel trehalose-rich yeast extract obtainable by the method of the invention. The novel trehalose-rich yeast extract comprises an amount of at least 15% (w/w) trehalose, based on dry matter. The invention also relates to the use of the novel trehalose-rich yeast extract as an additive in a cosmetic, pharmaceutical, food or beverage product.

The present invention relates to a yeast-derived polysaccharide inducing Treg cells and a use thereof and, more particularly, to a polysaccharide comprising mannan and β-glucan, an composition for immunomodulation comprising the polysaccharide as an active ingredient, a pharmaceutical composition or food comprising the polysaccharide as an active ingredient for prevention or treatment of immune disease or inflammatory disease, a method for preparation of regulatory T cells by using the polysaccharide, a cell therapeutic agent comprising the regulatory T cells prepared by the preparation method as an active ingredient, and a treatment method using same. Even at a low dose, the novel polysaccharide according to the present invention allows the production of tolerogenic antigen presenting cells through the β-glucan and mannan structure retained therein, whereby the novel polysaccharide can induce the differentiation or production of antigen-specific regulatory T cells (Treg cells) to modulate the target immune system with low adverse effects. Therefore, MGCP and the Treg cells induced by the polysaccharide are effective for preventing or treating immune disease or inflammatory disease.
