Protein energy malnutrition and vitamin A deficiency are the most documented problem in the country of Ethiopia. Developing of weaning foods in the country has a mile stone contribution for this problem. The effect of two factors, blending ratio (barley, faba bean and carrot) and faba bean sprouting duration for days 2 and 3 were studied. The experiment was conducted using custom design by JMP8 software. Mixture response surface methodology was applied for the analysis of data. Optimum value (16.01-16.22%) of protein was obtained at day three when proportion ranged from 50 to 65% barley, 30 to 35% of faba bean and 5 to 10% carrot. The moisture, ash, crude fiber, crude fat , crude protein and carbohydrate content of the blended flours had ranged from 5.30 to 5.48%, 3.30 to 4.09%, 4.85 to 5.38%, 1.41 to...

Different aerial parts of the plant were considered for the experiments and consisted in a completed randomized design of comparison test. The proximate composition and gross energy value of the plant parts were analyzed using AACC (2000) and the data were analyzed by SAS software version 9.1. The results revealed that Abyssinian thyme herb aerial parts the Flower, Leaf and Whole plant contained ash (11.32, 11.0 and 10.2%), crude protein (11.08, 9.97, and 9.6%), crude fat (6.1, 2.75 and 6.14%), crude fiber (15.1, 15.5 and 18.7%), moisture (11.13, 11.13 and 10.6%) and total carbohydrate (56.38, 60.75and 55.33%), respectively. Among the proximate composition of Abyssinian thyme herb found in this work has a high carbohydrate content and it was low in fat and protein levels. From the three aerial parts of the Abyssinian ...

Higher prevalence rates of S. aureus (54.9 vs. 28.3%) and Salmonella (12.9 vs. 11.1%) were observed for raw milk distributed via collection milk collection centers (MCC) compared to those via dairy farms (DF). Prevalence found for S. aureus in traditionally fermented milk averaged only 3.7%. Although the 90% CI estimated probabilities of exposures to S. aureus due to DF and MCC raw milk consumption at levels higher than the D‐R value found were 10.6 and 23.5%, respectively, exposures to Salmonella were within the pathogen's tolerable limit. While annual likely of risk of illness by S. aureus due to DF and MCC raw milk consumptions resulted in up to 24.2 and 48.3% estimated illnesses, respectively, traditionally fermented milk consumption was found very much less risky; and resulted only 2.5% estimated illnesses per‐serving‐per‐year. The corresponding values for Salmonella per‐serving‐per‐year estimated illnesses via raw milk sales are, respectively, 5.72 and 11.41% compared to 1.8 and 4.02% when they come in boiled forms.

Foodborne illnesses represent a public health problem in developed and developing countries. They cause great suffering and are transmitted directly or indirectly between animals and humans and circulate in the global environment. E. coli are among them, causing a major public health problem. The aim of this study was therefore to study the antimicrobial resistance profile of E. coli from raw cow milk and fruit juice. Materials and Methods. A cross-sectional study was conducted from October 2016 to June 2017 on 258 samples collected from milk shops (n=86), dairy farms (n=86), and fruit juice (n=86) in different subcities of Mekelle. Bacteriological procedures were used for isolation of E. coli in the collected samples and for identification of the antimicrobial resistance profile. Result. The overall mean viable bacterial count and standard deviation of samples from milk shop, fruit juice, and dairy milk were found to be 8.86 ± 107, 7.2 ± 107, and 8.65 ± 107 CFU/ml and 33.87 ± ...

Different aerial parts of the plant were considered for the experiments. The mineral content, anti-nutritional and pro-vitamin”A” value of the plant parts was analyzed using AOAC (2000). Mineral contents such as iron (Fe), zinc (Zn), calcium (Ca), copper (Cu) and magnesium (Mg) were determined by Atomic Absorption Spectrophotometer and Condensed tannin, total phenolic content, carotenoids, beta carotene and retinol equivalent vit “A” were determined by UV/vis Spectrophotometer and the data were analyzed by SAS software version 9.1. The results revealed that Abyssinian thyme herb aerial parts (F, L & W) contained Zinc (9.19, 9.01 and 8.36 mg/100 g); Iron (0.022, 0.0022 and 0.012 mg/100 g), copper (0.038, 0.054 and 0.045 mg/100 g), Magnesium (2.47, 2.32 and 2.1 mg/g ) and Calcium (392, 379.5, and 355.3 mg/g), r...
