This study was carried out to develop probiotic fermented beverages. The commercial strain Bifidobacterium infantis 20088 was used. The growth of the strain and its related physiochemical changes during fermentation was evaluated. The strain survival during refrigeration storage was also examined. In addition the chemical composition of different fermented beverages at initial and maximum growth of the strain were also determined. Growth media were formulated from reconstituted skim mil...

The samples were collected from Alradoum area Southern Darfour State – Sudan. Samples were well prepared and kept in d...
ABSTRACT The seeds and peels of African star apple (Chrysophyllum albidum) (“udara”) were split, followed by removal of mucilage from the seeds and subsequent cracking of the seed shells, and de-pulping of the peels. The seed cotyledons and peels were blanched at 1000C for 2,4 and 6 mins, wet milled with water in 1: 1.5 ratio, sieved with muslin cloth to obtain the extracts which were pasteurized at 800C for 10mins and stabilized with 0.2, 0.4, 0.6, 0.8 and 1.0 (g/litre) concentrations o...
ABSTRACT The main goal of this study was to develop aready-to-serve gluten free vegetables based infant food product with high nutritional value, high physicochemical, microbial and organoleptic characteristics in order to contribute in solving the problem of children malnutrition in Sudan. The results obtained in this study indicated that the developed vegetables based infant food product was found with high levels of available carbohydrates (68.32%), total sugars (12.75%) and protein (6.7%...
Abstract This study was carried out to estimate acrylamide content in some Sudanese foods including Rugag (thin sheets of baked wheat flour), homemade biscuit with ammonium bicarbonate and homemade biscuit without ammonium bicarbonate. Rugag was prepared according to the traditional method employed in Sudanese house hold. Prepared from 72% extraction wheat flour, sugar, milk powder, vanilla, corn flour, salt, and baking powder, baked in thin sheet on hot steel plate at 170 ˚C for 40 seconds...
Abstract Construction industry is one of the major international industries and always takes place as agreat investment which needs huge capitals and wide experience. Contracts in the construction industry are fundamentals issues however technical support is necessary in all construction contracts for proper conduct adequate outputs. Usually contracts between different parties (contractor,client and consultant) include rights and obliquation which may not always be in abalance way. This migh...
Abstract Three brands of non-alcoholic carbonated soft drinks (CSDs) from three plants in Khartoum, Sudan which were named A, B and C; were examined for their microbiological quality. Plants were selected according to their quality system ‘A being the highest C being the lowest’. Samples were analyzed for (TBC); Yeast and Mold, coliform bacteria and acid tolerant microorganisms using membrane filtration method. Carbonated soft drinks from Plant C were the worst in microbiological quality...
ABSTRACT The aim of this research was to establish whether Mursik, a Kenyan traditional fermented milk product, contained Exopolysaccharides (EPS) and EPS producing Lactic acid Bacteria (LAB). It also sought to establish the optimum conditions for their production in Mursik. Samples of Mursik were collected from 39 randomly selected homesteads in Njoro District, Nakuru County, Kenya, and transported to Egerton University for analysis. Their EPS levels were determined by isolating them and qu...
ABSTRACT Mycotoxin and Brucella abortus contamination of milk along the dairy value chain is of public health concern and contributes to food insecurity. Animal feeds that are contaminated with mycotoxin causing fungi pass the contaminationtion to the milk. Inhygienic handling of milk can lead to Brucella contamination of milk. This study aimed at determining the on-farm risk factors associated with Mycotoxins and B. abortus occurrence and their prevalence on smallholder farms at rural and p...
ABSTRACT Milk production in Kenya is dominated by smallholder dairy farmers who are faced with challenges on feeding dairy cows. This is generally due to inadequate and low quality feeds and high cost of inputs. Thus, utilization of inexpensive nutrient dense feed supplement such as liquid brewer’s yeast (LBY) is inevitable. However, LBY is rarely used due to its short shelf life and lack of technical information on effect on milk quality. This study was performed to investigate the approp...
In this work, the antimicrobial properties of fresh Buchholzia Coriacea (wonderful kola) and its extracts was investigated. The proximate composition of the fresh kola was also determined. B. coriacea was dried, milled and extracted using two different solvents of varying polarity: hexane and methanol. The effect of the fresh kola, hexane and methanol extracts was tested on some food borne pathogens. This was evaluated by measuring the zone of inhibition on nutrient agar for bacteria and malt...
Abstract The effects of adding different concentrations of Aframomum danielli (powder and ethanoic extracts) on nutritional, physico-chemical and densory properties of wheat flour bread were examined. Using alveograph and consistograph, the physical properties of the dough-water absorption capacity, tenacity, extensibility, strength of flour and peak time were evaluated
ABSTRACT The milk marketed in Kenya has been reported to be of poor quality and does not meet national and international standards due to high bacterial load, high somatic cell count, adulteration and antibiotic residues. The study investigates the raw milk quality, adherence to hygienic code of practice and identifies the critical control points for improved raw milk quality in the smallholder supply chain. Compliance to hygienic code of practice was assessed using questionnaires. The facto...
Abstract The postharvest losses in fruits and vegetables in developing countries vary between 15-90%. Many organizations are actively promoting the processing of fruits and vegetables to find a solution to the difficulties encountered in storing large quantities of fresh produce without incurring heavy losses. This study evaluated the chemical, microbiological and sensory properties of leather blends produced from 'Ogbomoso' mango and carrot. Purees of mango (Mangifera indica 'Ogbomoso') and...
ABSTRACT Potato (Solanum tuberosum L.) is bulky and perishable with up to 50% of losses in 3-5 months of storage. Losses can be reduced through processing into less bulky and more stable products. The aim of this study was to investigate morphological and biochemical factors which affect potato quality, effect of potato cultivars and fermentation on quality of French fries and crisps as well as starch characteristics. Cultivars used included vartieties like Gikungu, Kigega, Kinigi, Kirundo, ...
