| Abstract |
Glucono-delta-lactone (GDL), lactic acid bacteria (LAB) and their metabolites (LABM) were added to buffalo's milk before cold storage for 72 h. Numbers of total bacteria (TBC), psychrotrophs (Ps.BC), prteolytic (PBC) and lipolytic (LBC) bacteria were counted during storage period. Ail milk samples were analysed for pH, acidity, TN and NPN ann for stability to ethanel (AS) arid to rennin (RCT). The resultant curd was tested for curd tension (CT) and curd syneresis (CS).
Results showed that the prementioned bacteria gradully increased during storage of the untreated milk whereas.the applied treatments decreased the numbers of TBC, PsBC. PSC and LBC during storage period and the best results were achieved using LABM.
Acidity and NPN/TN gradually increased during storage period but with different rates. AS was the highest in the control milk and the lowest in LABM-treated milk, whereas RCT was longer in the firs, case and shorter in the second one. GDL slightly increased CT and LABM decreased it. An the applied treatments increased slightly CS when compared to the untreated milk.
