| Abstract | ||
| A total of 36 samples of Laban Rayeb were collected from 12 different small dairy plants in Assuit Governorate. samples were analyzed for their chemical composition and microbiological quality. The Results showed that the average values of acidity %, moisture, total solids, fat, total nitrogen, soluble nitrogen, soluble nitrogen coefficient were 1.1, 88.29, 11.66, 2.41, 0.52, 0.17 and 4.87, respectively. Moreover, microbiological analysis revealed that the log10 of total bacteria count ranged from 7.03 to7.21cfu, counts of lactic acid bacteria counts ranged from 5.781 to 6.353cfu, and the coccus group ranged from 5.83 to 6.29cfu and proteolytic bacteria ranged from 4.36 and 6.89cfu. Finally, yeasts and moulds count ranged from 0.00 to 5.21cfu in fresh Rayeb milk samples. Coliform bacteria couldn't be detected in all of the examined samples. | ||
