Yeast Extract


SK Yeast Extract contains high natural 5'-IMP and 5'-GMP. These contents are from RNA-rich yeast developed by NPI. It has a smooth flavor and doesn't have a disagreeable taste.

The product does not contain any organic chlorine compounds (MCP, DCP) as we employ the enzymatic hydrolysis method, rather than the hydrochloric acid hydrolysis method. Also, there are not any genetically modified organisms (GMO) in the product.

SK Yeast Extract is not only an excellent seasoning, but also has special effects such as masking disagreeable tastes or smells.
