Prickly pear FJ underwent a lactic fermentation since a high
lactic acid content was detected in the resulting KLB and also
because of the production of acetic acid (heterolactic fermentation).
For this KLB, a moderate amount of ethanol was registered after
fermentation, probably due to the quicker development of LAB over
yeasts. Except for prickly pear KLB, lactic and acetic acid levels
registered in this work are quite low to significantly affect the
sensory properties of the final products. Furthermore, the ethanol
levels were generally in line with the reduction of soluble solid
content; thus, the main fermentation in KLBs appears to have been
yeast-based.
