Chemical and Microbiological Properties of Different Sudanese Porridges Madida

Abstract

The aim of this study was to determine the nutritive value and safety of medida (Sudanese thin porridges). Samples were collected from different locations in Khartoum State. The samples were medidat tamur, millet medida and medidat um genger. The moisture content of Um ginger in Khartoum North, Omdurman and Khartoum was 67.57%, 65.45% and 63.83%, respectively. Date medida was 64.48%, 63.09% and 67.19%, respectively. Millet medida was 67.48%, 65.22% and 66.98%, respectively. Ash content of medidat Um ginger in Khartoum North, Omdurman and Khartoum was 0.8%, 0.6% and 0.4%, respectively. Date medida was 0.5%, 0.4% and 0.3%, respectively. Millet medida was 0.5%, 0.5% and 0.4, respectively. Protein content of medidat Um ginger in Khartoum North, Omdurman and Khartoum was 3.5%, 1.5% and 1.8%, respectively. Date medida was 0.8%, 0.3% and 0.4%, respectively and millet medida was 1.8%, 2.0% and 1.5%, respectively. Fiber content of medidat Um ginger Khartoum North, Omdurman and Khartoum was 0.6%, 0.3% and 0.2%, respectively. Date medida was 0.3%, 0.2% and 0.3%, respectively. and millet medida was 0.2%, 0.3% and 0.3%, respectively. Fat content of medidat Um ginger in Khartoum North, Omdurman and Khartoum was 0.8%, 0.4% and 0.7%, respectively. Date medida was 0.2%, 0.1% and 0.1%, respectively. and millet medida was 0.7%, 0.6% and 0.6%, respectively. Carbohydrates content of medidat Um ginger in Khartoum North, Omdurman and Khartoum was 26.54%, 31.57% and 32.96%, respectively. Date medida was 33.59%, 35.74% and 31.62%, respectively. and millet medida was 29.13%, 31.12% and 29.99%, respectively. Bacterial Number of medidat Um ginger in Khartoum North, Omdurman and Khartoum was 6.8x106, 4.8x104 and 4.9x104(cfu/g) respectively. Date medida was 5.6x105, 6.8x106 and 5.5x105(cfu/g), respectively. and millet medida was 6.6x106, 5.5x105 and 5.8x105(cfu/g), respectively. Moulds and yeasts content of medidat Um ginger in Khartoum North, Omdurman and Khartoum was 3.6x103, 3.5x103 and 2.6x103(cfu/g), respectively. Date medida was 2.7x102, 3.4x102 and 2.6x102(cfu/g), respectively. and Millet medida was 2.5x102, 3.5x103 and 3.5x103(log10cfu/g), respectively. Staphylococcus aureus content of medidat Um ginger in Khartoum North, Omdurman and Khartoum was 2.8x102, 2.5x102 and 2.6x102 (cfu/g), respectively. Date medida was 2.6x102, 2.6x102 and 2.5x102 (cfu/g), respectively. And Millet medida was 2.7x102, 2.6x102 and 2.8x102(cfu/g), respectively. Total Coliforms content of medidat Um ginger in Khartoum North, Omdurman and Khartoum was 16.6, 1.0and 0.0 respectively. Date medida was 0.0, 13.3 and 5.3, respectively. and millet medida was 9.0, 7.3 and 12.0(cfu/g), respectively. E. coli content of medidat Um ginger in Khartoum North, Omdurman and Khartoum was 4.3, 0.0 and 0.0(MPN/g), respectively. Date medida was 0.0, 4.0 and 0.0(MPN/g), respectively. and millet medida was 0.0, 0.0 and 2.0 (MPN/g), respectively. From the results the Salmonella in millet medida was not detected in the different locations (Omdurman, Khartoum and Khartoum North). Um ginger medida from Khartoum has a positive result of Salmonella, while samples from Omdurman and Khartoum have negative result (not detected). The samples of date medida from Omdurman have positive results, while the samples from Khartoum and Khartoum North have negative results (not detected). According to the results of this study these Sudanese medida are not healthy that they content pathogenic bacteria. Accordingly the consumers should be pay attention and care. Also intensive advice about healthy handling of these products should be made available for both sellers and consumers.
