Sixteen different yoghurts were prepared combining 3 types of fruit fibers (plus control without fiber) with only one of the 4 probiotic strains. Two independent fermentations were performed on
different days and replicated twice. After inoculation, the fermentations were carried out at 42 °C in a CINAC system as described by Spinnler and Corrieu (1989). When the desired pH was reached (pH 4.5), the flasks with the yoghurts were cooled to 15 °C in ice bath, and then the clot was broken. Afterwards, the fermented milk was packed and sealed in 50 mL polypropylene pots and cooled to 4 °C. All sampling and analyses were performed after 1 day, 14 days and 28 days of cold storage at this temperature.
