Abstract
This study aimed to evaluate the safety and quality of frozen dairy desserts sold in different shops and supermarkets in Alexandria city. Eighty samples of ice cream of 4 different flavours (Vanilla, Chocolate, Mango and Strawberry) 20 of each as well as 20 samples of frozen yoghurt were collected randomly from Alexandria city. All samples were subjected to sanitary and microbiological evaluation. Results showed that samples subjected to Methylene Blue Reduction test revealed that 15(75%), 10(50%), 7(35%), 2(10%) of examined of ice cream samples (Vanilla, Chocolate, Mango and Strawberry) were qualified as Grade (1), respectively. While samples with Grade (2) were 2(1%), 1(5%), 0(0%), 1(5%) of examined samples, respectively. While 2(10%), 2(10%), 6(30%), 2(10%) of the four different flavours were Grade (3) with poor quality respectively. Also 1(5%), 7(35%),7(35%) and 15(75%), of samples were grade (4), respectively. 17(85%) frozen yoghurt samples were categorized as Grade (4) and 3(15%) showed grade(3) for methylene blue reduction test; mean values of aerobic mesophilic count (cfu/g) in examined flavoured ice cream (Vanilla, Chocolate, Mango and Strawberry) were 1.5x 105 ± 6.1x104, 9.5x〖10〗^6±6.4x〖10〗^5, 4.8x 106 ± 2.4x106 and 5.1x 107 ± 1.8x 107, respectively. Also, mean values of coliforms count (MPN/g) were 2.5x102 ±7.1x10, 6.6x〖10〗^2±2,5x〖10〗^2, 9.9x103 ± 6.3x103, 4x103 ±1.4x103 and 1.5x〖10〗^2±2.9x1 , respectively; mean values of Staph.aureus count (cfu/g) were 1.6x 102 ±7.0x 10, 3.4x102±9.4x102, 1.9x103±1.5x103, 7.4x102±2.9x102 and 3.33x〖10〗^2±1.2x〖10〗^2, respectively. Finally, mean values of mold count(cfu/g) were 2.2x102 ± 8.4x10, 9.6x〖10〗^2±4.4x〖10〗^2, 3.2x103±1.3x103, 3.7x103±1x 103and 1.3x〖10〗^4±6.4x〖10〗^3in examined Vanilla, chocolate, Mango, Strawberry ice cream samples and frozen yoghurt respectively.
