Mate Hidvegi (born 9 November 1955 in Budapest, Hungary) is a Hungarian biochemist and co-inventor of Avemar and Oncomar, fermented wheat germ extract based nutraceuticals.

[citation needed] After finishing university, he worked in the cereal industry and was co-developer of a patented feed advisory system based on near infrared ingredient data.

In 1996 Hidvegi was co-founder of Biromedicina (joint stock company), what is now called The First Hungarian Corporation for Cancer Research and Oncology.

The company’s mission was to market Hidvegi's product Avemar, a fermented wheat germ extract-based nutraceutical.

In 2009 Hidvegi marketed a new dietary food for special medical purposes for cancer patients based on the Avemar, which was sold as Oncomar and (in the U.S.) AvéUltra.
