| Abstract | ||
| Glucono-delta·lactone (GDL). lactic acid bacteria (LAB) and their metabolites (LABM) were added 10 buffalo's milk before cold stOl'age for 72 h. Numbers of total bacteria (TBC). psychrotrophs (Ps.aC). prteolylic (PBC) and lipolytic (LBC) bacteria were counted during storage period. All milk samples were analysed for pH. acidity. TN and NPN and for stability to ethanol (AS) and to rennin (RCT). The resultant curd was tested for curd tension (Cn and curd syneresis (CS). Results showed that the prementioned bacteria gradually increased during storage of the untreated milk whereas the applied treatments decreased the numbers of TBC, PsBC. PBC and LBC during storage period and the best results were achieved using LABM. Acidity and NPNrrN 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 ReT was longer in the fil'$t case and shorter in the second one. GDL slightly increased CT and LABM decreased it. All the applied treatments increased slightly CS when compared to the untreated milk | ||
