    Fermentation Capacity of Yeasts Using Mango (Mangifera indica Linn.) as Substrate
    (Food Science and Quality Management, 2013) Kamassah, Anthony K.Q.; Saalia, Firibu K.; Osei-Fosu, Paul; Mensah-Brown, Henry; Sinayobye, Emmanuel; Tano-Debrah, Kwaku
    The goal of this study was to address the problem of large post harvest losses of mangoes by employing yeast fermentation technology to produce a more stable, value-added product in this case fruit wine. The design of the study involved determination of the fermentative capabilities of four commercial yeast types on musts obtained from an improved (Keitt) mango cultivar that is popularly cultivated in some parts of Ghana for export. The characteristics of the mango musts that were monitored included total soluble solids (TSS), pH and total acidity (TA), microbial populations (aerophilic mesophiles, yeasts and Acetic acid Bacteria), alcohol content and colour over the course of the fermentations. Descriptive and hedonic sensory evaluation was carried out on the ferments obtained from all treatments. Results showed that two of the yeast types namely; Red Star Pasteur and Red Star Montrachet displayed superior fermentation characteristics and produced mango wines that were acceptable by both descriptive and affective sensory panels.
