Some leading food bioprocessing technologies are dairy processing, alcohol and beverage processing. Production of alcoholic beverages include: wine, beer, whiskey, rum, shake, etc. utilizing microorganisms like Clostridium acetobutylicum, Lecuonostoc mesenteroides, Aspergillus oryzae, Saccharomyces cerevisiae, Rizopus sp., Mucor sp., etc. Biotechnologically produced organic acids like citric acid, acetic acid, gluconic acid, D-Lactic acid, fumaric acid, etc. also have very high market value.
The application of biochemistry can result in (a) new ways of producing existing products with the use of new inputs, and (b) new ways of producing new products. Examples of the former include the production of gasoline from ethanol which in turn is produced from sugar; the production of insulin using recombinant DNA technology; the production of hepatitis B vaccine using recombinant DNA technology and the extraction of copper using mineral leaching bacteria. The alternative inputs are oil for gasoline, porcine pancreases for insulin, human blood for hepatitis vaccine, and the conventional mining techniques for copper. ...
