Microbiological safety and stability of novel green sauces made with sea fennel (Crithmum maritimum L.)

Due to consumers' demand for ready-to-eat foods, in the last decades production of sauces has shifted from home-made to commercial practice. Besides to palatability and nutritional value, safety and stability are key issues of industrial sauces. The present study was aimed at evaluating the microbiological stability and safety of industrial-scale prototypes of two novel green sauces made with sea fennel (Crithmum maritimum L.) as the main ingredient. To this end, accelerated shelf-life and microbial challenge tests were performed to assess: (i) the microbiological shelf-stability of the two sauces stabilized by heat treatments commonly applied at industrial scale to inactivate vegetative cells of spoilage microorganisms and pathogens in vegetable preserves (F
