S. aureus and Z. bailii were the main microbial contaminants found in this investigation. According to reports on the surviving capacity of S. aureus (Valero et al., 2009), an aw value of 0.87 permitted a slight growth and the permanence of this pathogen at the initial levels for fifteen days in the food supplement (Fig. 3).From a scientific point of view, there was no element which supported a correlation between the observed microorganisms (species and enumeration) and the spoilage.
