In the framework of the trend towards lowering the salt content in meat products, an experiment was set up to determine combined effect of reducing the salt content with 20% or 40% and adding 2% or 3% Purasal® Opti.Form PD 4 (a mixture of potassium lactate and sodium diacetate) on the shelf-life of a pre-packaged cooked meat product. By means of a challenge test with a mixture of two Lactobacillus sakei strains and a Leuconostoc mesenteroides strain, it was observed that use of lactate/diacetate mixture enabled a 40% reduction of the salt content in this cooked meat product, whereas the microbial shelf-life was significantly increased.
