Fermentation is among the oldest techniques for processing food. The term “fermentation” refers to a procedure where chemical changes take place in organic substrates through the action of enzymes created by microorganisms. For instance yeast enzymes transform starches and sugars into alcohol, and proteins are transformed into peptides or amino acids.
