While studying this process in 1897, Eduard Buchner of Humboldt University of Berlin, Germany, found that sugar was fermented even when there were no living yeast cells in the mixture, by a yeast secretion that he termed zymase. In 1907 he received the Nobel Prize in Chemistry for his research and discovery of cell-free fermentation.One year prior, in 1906, ethanol fermentation studies led to the early discovery of NAD+. Uses Food fermentation has been said to serve five main purposes: # Enrichment of the diet through development of a diversity of flavors, aromas, and textures in food substrates # Preservation of substantial amounts of food through lactic acid, alcohol, acetic acid and alkaline fermentations # Biological enrichment of food substrates with protein, essential amino acids, essential fatty acids, and vitamins # Elimination of ant nutrients. # A decrease in cooking times and fuel requirements Risks of consuming fermented foods Food that is improperly fermented has a notable risk of exposing the eater to botulism. Alaska has witnessed a steady increase of cases of botulism since 1985. Despite its small population, it has more cases of botulism than any other state in the United States of America. This is caused by the traditional EskimoShow MoreRelatedChemistry Career Research Project: Forensic Science547 Words   |  2 Pagesin the first years of college, certain courses should be taken. English, Chemistry, Physics, and Biology are the most important but it can also be of assistance to take classes such as Genetics, Statistics, Crime Scene Investigation, and Forensic DNA Analysis. In forensic science, various chemistry degrees are mandated. Popular choices include Analytical Chemistry, Organic Chemistry, Drug Chemistry, and Biophysical Chemistry.
