who coined the term zymase for enzymes in yeast
Zymase Some science historians[3] suggest that Eduard Buchner, in his 1897 work, merely repeated experiments already made by Antoine Béchamp in 1857. This is not the case : what Buchner obtained with yeast zymase, and without yeast cells, was alcoholic fermentation, while Béchamp had explicitly stated that, in absence of yeast cells, and by use of what he, also, called "zymase", he obtained only sugar inversion and no alcoholic fermentation.[4] According to K.L. Manchester,[5] what Béchamp called "zymase" was invertase.
High-fructose corn syrup Commercial production of corn syrup began in 1864.[3]:17 In the late 1950s, scientists at Clinton Corn Processing Company of Clinton, Iowa tried to turn glucose from corn starch into fructose, but the process was not scalable.[3]:17[24] In 1965â€“1970 Yoshiyuki Takasaki, at the Japanese National Institute of Advanced Industrial Science and Technology (AIST) developed a heat-stable xylose isomerase enzyme from yeast. In 1967, the Clinton Corn Processing Company obtained an exclusive license to a manufacture glucose isomerase derived from Streptomyces bacteria and began shipping an early version of HFCS in February 1967.[3]:140 In 1983, the FDA approved HFCS as Generally Recognized as Safe (GRAS), and that decision was reaffirmed in 1996[25]
