FPE was produced in our laboratory according to the method described by Kantachote et al. [19]. The fermentation process lasted for 2 months. At that time, it composed of 1.90% total acidity, 0.58% lactic acid and 0.15% acetic acid with a pH of 3.61 and an EC value of 3.51 mS cm- 1. In addition to the nutrients, the population of HPC, yeasts and LAB were estimated in the region of 106 cfu mL- 1 for each group. FPE was kept in a cold room until used.
