Results showed the suitability of three Andean tubers to be used
as raw material for lactic acid fermentation with the potentially
probiotic L. brevis CJ25 strain. Especially Churque~na potato allows
the development of a solid fermented food, called Potato Cheese.
Potato Cheese is proposed as a good LAB carrier because the strain
remains viable after four weeks of storage at 4 C, showing metabolic
activity with concomitant pH decrease, which prevented
contamination by pathogenic and spoilage microorganisms.
L. brevis CJ25 could also survive the GI tract at significant levels. Due
to these desirable in vitro probiotic properties, this strain is
considered a good candidate for further investigations. As consumer
demand for nondairy-based probiotic products has
enhanced in recent years, Potato Cheese is a promising novel
functional food with high nutritional value, free of cholesterol and
lactose and its development may convey a favorable impact in
regional economies.
