OCCURING SOME BIOCHEMICAL REACTIONS IN FERMENTED MEAT PRODUCTS AND THEIR EFFECTS ON AROMA DEVELOPMENT

Abstract

Glycolysis, lipolysis and proteolysis are the main biochemical reactions which effect characteristic flavour, aroma, color and texture development of fermented meat products. These reactions are results of the microorganisms or endogenous meat enzymes. The products which are results of glycolysis are firstly responsible from decreasing of pH. Volatile compounds from glycolysis effect aroma. Compounds formed by lipolysis are the main reason that effect aroma. 60 % volatile compounds formed in fermented products are results of lipolysis. Because of low pH, low water activity and high salt concentration, proteolysis occurs in a very decreased level and form only a little part of all volatiles. For this reason proteolysis effects aroma much more than flavour.
