dc.descriptionThe survival of six probiotic wild strains of Lactobacillus rhamnosus was compared with that of a type strain during 78 days of storage at 25 and 5 °C in peach synthetic medium (PSM) and commercial peach jam (PJ). Changes in viable cell counts, pH values, sugar content, and colour parameters were monitored. All strains exhibited better performances in PJ than in PSM, showing count values higher than 7 Log cfu g–1 up to 78 days of storage at 5 °C. Almost all wild strains remained above the critical value of 6 Log cfu g–1 in samples stored at 25 °C up to 45 days, while the Lb. rhamnosus GG type strain, used as control, was not able to survive later than 15 days. In the synthetic medium used, the strains showed better survival in the samples incubated at 25 °C, remaining viable above the critical level up to 45 days of storage, except for the strain H12. The probiotic cultures added to jam did not significantly change the colour parameters of the product; however the metabolism of lactobacilli did cause changes in the pH and in the composition of sugars.
