| Popis: | The interest about probiotic bacteria supplementation in fruit beverages has been increased recently in order to develop functional beverages without lactose. That is a technological challenge since pH and storage temperature can affect their viability. The aim of this study was to evaluate the viability of three commercial probiotic strains (L. paracasei, L. casei and L. rhamnosus) in mango beverage stored at 4°C. This research was developed in three stages: the assessment of the acid strain tolerance, the selection of a prebiotic as cellular protectant against environmental stress, the evaluation of physiochemical and sensory stability during storage. L. casei was chosen as the most stable strain with FOS at 5% as a prebiotic substance that stimulated its growth. At the final stage, it was found that L. casei produced significant changes in pH and titratable acidity in mango beverages after one week at 4°C, which was also detected by consumers with good sensory acceptance |
