    Abstract:
    The physical, chemical and microbiological characteristics of reformulated meat-based frankfurters, derived from an ancient Roman cookbook and produced from pork meat, emmer wheat, almond, fish sauce and spices, were investigated during storage. Two different formulations were considered, with pork thigh and pork shoulder muscles, respectively. The products contain 13-16% protein, 14-19% fat, 14% carbohydrates, >7% fibre and a polyunsaturated/saturated fatty acids ratio above 0.4. During the 24 days of storage, both products evidenced a decrease in the pH and increases in the total volatile nitrogen content and TBARs value, whereas, the aw remained stable. From a microbiological perspective, increases in the total viable count and lactic acid bacteria up to 4.8 log cfu/g occurred during storage, but no pathogens were found. Sensory analyses revealed a change in odour and flavour at 18 days, with the detection of a fermented and rancid taste. Survival sensory analysis defined a shelf life of the products of between 18.6 and 22.7 days.
