Those characteristic make it undesirable to customer. Besides, high pH value makes it available to pathogenic ~nicroor.ganismt o grow. The qualities of DFD meat can be enhanced by ferment it with starter bacteria. Adaptable starter cultures are a syarat to obtain optimum fermentation. Another important sjarat is starter cultures ability to produce antimicrobials so it can be maintain product's shelf-life and also regarded it as functional food product.
