Probiotic Lactobacillus paracasei IMPC 2.1 strain delivered by ready-to-eat swordfish fillets colonizes the human gut after alternate-day supplementation

Abstract

Ready-to-eat (RTE) swordfish fillets were used in a human feeding study involving 8 volunteersto assess the suitability of the fish matrix in delivering viable cells of the probioticLactobacillus paracasei IMPC 2.1. The strain did not affect the protein profile and total freeamino acid content along the fillet shelf life. Volunteers consumed 100 g of probiotic RTEportion delivering 9 log CFU of bacterial cells, on alternate days over 20 days. Five subjectsresulted to be colonized by the probiotic strain, at levels ranging from 6.30 to 7.74 log CFU/gof faeces, after eating 5 portions of the product (T1, 10 days). After 20 days (T2, 10 portions)the probiotic strain was recovered in the faeces of all subjects at concentrations rangingfrom 6.15 to 7.47 log CFU/g. This study demonstrated that 5 portions of probiotic RTE fishfillets consumed on alternate days allowed the transient colonization of gut by L. paracaseiIMPC 2.1.
