摘要
In the present study, the physicochemical changes (titratable acidity, fat, density and solids-not-fat), microbiological and overall acceptance) of whole ultra-heat-treated (UHT) milk marketed in Tehran, Iran were assessed during the storage period (0, 90 and 180 days). Five brands of whole UHT milk were selected to determine the quality of samples. The results showed that the fat content decreased. However, titratable acidity and density of brands C and B respectively were not in accordance with standard. Total bacteria count tests indicated that there was less than 10 cfu D mL microorganism in UHT milk samples over storage time (0, 90 and 180 days). All brands were similar in respect of months storage.
