The ON/OFF regulator built into the gene is called a molecular switch, and the plant metabolic regulation technology that finds and controls it in detail is called a molecular switch technology.
INGR is conducting research to maximize the content of efficacy components by exploring and controlling molecular switches of natural metabolism genes in various plant cells.
VinoChocolate released by INGR is a grape flower cell extract that amplifies the contents of resveratrol and viniferin by controlling the molecular switch of the grape STS gene while culturing grape flower cells.
INGR activates the molecular switch while culturing the most actively dividing flower anther cells among grape flower cells, amplifying the content of viniferin to 500 mg/L (ppm). This is 260 times more than the amount of viniferin in wine.
