The objective of this study was to evaluate the influence of microencapsulated sodium chloride (Cap-Shure® Sodium Chloride 85 Salt), sodium nitrite, and lactic acid on the microbiological stability of pork meat (loin and neck). Experimental primal cuts were stored at a temperature ranging from to 2 to 4ºC during 2 and 14 days, and at a temperature of -18ºC (frozen) during 3 and 9 months after their having been packed in a laminate foil ‘PAPE’ bags that were vacuum closed. Generally, after the 2 and 14 day storage of meat under chilled conditions, it was stated a higher contamination level caused by aerobic bacteria in the neck meat compared with the loin meat investigated. Nitrite and lactic acids, if added together with sodium chloride, positively influenced microbiological stability of the meat stored 14 days in a cold room. If the period of storing meat under freezing conditions was prolonged from 3 to 9 months, it was usually stated a reduced aerobic bacteria count in slices with salt, and an increased number of lactic acid bacteria irrespective of additive types applied. It also caused an essential reduction in the number of coli forms in the loin meat; however, with regard to the neck meat, the count of coli forms did not decrease. From the microbiological point of view, the application of microencapsulated salts was safe and constituted no microbiological danger for meat stored under chilling conditions even as long as 14 days.
