INTRODUCTION TO FOOD MICROBIOLOGY



Development of history of food microbiology:


Year Events 

1782 -Canning of vinegar introduced by a Swedish chemist


1810 -Preservation of food by canning was patented by Appert in France


-Peter Durand was issued a British patent to preserve food in "glass, pottery, tin or other metals or materials." The patent was later acquired by Hall, Gamble, and Donkin, possibly from Appert


1813 -Donkin, Hall, and Gamble introduced the practice of post processing incubation of canned foods. 

-Use of SO2 as a meat preservative is thought to have originated around this time. 1825 - Patent preserving food in tin cans (Kensett and Daggett)


1835 -Patent making condensed milk (Newton in England) 1840 -Fish and fruit were first canned.


1842 -Patent freezing foods by immersion in an ice and salt brine (Benjamin in England)


1843 -Sterilization by steam was first attempted by Winslow in Maine.

 1853 - Patent for sterilization of food by autoclaving (Chevallier-Appert)


1854 -Pasteur began wine investigations. Heating to remove undesirable organisms was introduced commercially in 1867-1868


1855 - First to produce powdered milk (Wade in England)




1857 -Louis Pasture showed that souring milk was caused by microbes and in 1860 he 1857 -Louis Pasture showed that souring milk was caused by microbes and in 1860 he


demonstrated that heat destroyed undesirable microbes in wine and beer.


1865 -The artificial freezing of fish on a commercial scale was begun in the United States. Eggs followed in 1889.


1874 -The first extensive use of ice in transporting meat at sea. -Steam pressure cookers or retorts were introduced.


1878 -The first successful cargo of frozen meat went from Australia to England.


1880 -The pasteurization of milk begun in Germany. 1886 -Krukowitsch was the first to note the destructive effects of ozone on spoilage bacteria. 1890 -The commercial pasteurization of milk begins n the United States.


-Mechanical refrigeration for fruit storage begins in Chicago 1907 -Metchnikoff and co-workers isolated, and named one of the yogurt bacteria, Lactobacillus bulgaricus.


-The role of acetic acid bacteria in cider production was noted by Barker


1908 -Sodium benzoate was given official sanction by the United States as a preservative in certain foods. 1916 -The quick freezing of foods was achieved in Germany by Plank, Ehrenbaum, and Reuter


1917 -Birdseye the United States began work on the freezing of foods for the retail trade.


-Franks was issued a patent for preserving fruits and vegetables under CO: 1920 -Bigelow and Esty published the first systematic study of spore heat resistance above 212°F.


The "general method" for calculating thermal processes was published by Bigelow et al the


method was simplified by Ball in 1923 1922 -Esty and Meyer established method for studying Clostridium botulinum spores in phosphate


Buffer at 18°F 1928 -The first commercial use of controlled atmosphere storage of apples was made in Europe (first


used in New York in 1940).


1929 -A patent issued in France proposed the use of high-energy radiation for the processing of foods.
