Changes in biogenic a
mines were followed during pork
meat storage, the
manufacturing process,and the storage of cooked cured pork shoulder to establish the sourcesof these a
mines in this typeof product. Microbial counts were also followed. Duringstorage of pork

mine, putrescine, and cadaverine. A biogenic a

mine for

med thatonly sper
mine and sper
midineshould be present in cooked pork shoulder, if fresh pork
meat is usedand a correct processing isfollowed. High levels of cadaverine, putrescine, tyra
mine, andhista
mine in cooked pork shoulderwould be an indicator of the use of poor hygienic quality
meat.Keywords: Biogenic a
