ABSTRACT Overweight and obesity is an escalating problem worldwide, yet extensive data especially in Africa is still lacking. The main objective of the study was to determine the prevalence of overweight and obesity and associated socio-economic factors, physical activity, and dietary intake among women in Nairobi, Kenya. A crosssectional design was used. Data on socio-economic factors of the women, their physical activity and dietary intake patterns, as well as anthropometric measuremen...
ABSTRACT Kenya has one of the highest mortality rates among children under five. Inadequate dietary intake and low socio-economic status may contribute to the prevalence of malnutrition. The main objective of the study was to determine the dietary intake, hygienic practices, morbidity and nutritional status of children under five years in Mukuru slums.The study is important for planning and development of nutritional and good sanitation policies. Descriptive research design was used for ...
ABSTRACT The effect of addition of processed soybean flour on the physicochemical characteristics of fermented maize dough was studied. Soybean flours; Full-fat, Extruded, and Defatted soy-flours were processed and added to maize dough before and after fermentation of the dough. The soy were added to the dough at 0,10,and 20 percent concentrations. The dough samples were also fermented at 0,6,24 and 4 8 hours respectively. Two traditional food products; Ga kenkey and Akasa (Porridge) were al...
ABSTRACT The quality of palm oil depends on the method of extraction. Mechanized methods of extracting palm oil result in better oil quality. In Ghana over 80% of palm oil is produced by small scale processors whose lack of mechanization results in poor oil quality. A study conducted in 2011 resulted in the development of an improved traditional process (ITP) to augment the quality of palm oil from the small scale. This study sought to compare palm oils from different processing scales to IT...
ABSTRACT Fish farming in Kenya is faced with the challenge of high cost of feeds because of the high cost of fish meal, an important protein ingredient incorporated into feeds. Thus, there is the urgent need for cheaper alternative protein sources that have similar or higher protein quality to partially or completely substitute fish meal in feeds. The effects of substituting fresh water shrimps meal (FWSM) with black soldier fly larvae meal (Hermetia illucens – BSFM) or adult cricket meal ...
ABSTRACT Raw camel milk production and marketing chain in Kenya was investigated for microbial infections and implications. Milk samples were taken using simple random sampling method in a clustered sampling plan. There were three cluster levels, the production, processing and market levels. Analysis of samples in the laboratory for enumeration and characterization was by standard methods as described in the methodology. Data analysis was done by Pearson correlation coefficient and chi-squar...
ABSTRACT Mango production in Kenya has been on the rise. In 2013 about 581,290 MT were produced of which 40% were lost due to lack of proper postharvest management practices. The greatest loss was through pest and microbial spoilage and chemical deterioration of nutrients. The study aimed at developing methods to preserve the nutritional quality and reduce post-harvest losses in the mango value chain. Using a structured questionnaire, randomly administered to 40 mango farmers, post handling p...
The Tea Research Institute (TRI) developed TRFK 306 tea clone which is rich in anthocyanin as a strategy to diversify Kenyan teas. TRFK 6/8 was used as a control in the study being a standard clone used at the TRI. TRFK 306 can be utilized non-processed but there is no well researched, documented data on the best brewing conditions. Consumers add edible acids to its brew to improve the colour and taste but information on the acid effect is scanty. Information on the quality of products m...
A study was conducted on the newly developed purple tea clones in Kenya. Green tea quality analyses on theanine and catechins were done using HPLC, while total polyphenols were done using the Folin- Ciocalteu phenol reagent method. Sensory analysis was also done on green tea samples. Plain black tea quality parameters were determined (total theaflavins and individual theaflavins, brightness and total colour percentages, total thearubigins and fractions and total soluble solids) for all t...
vi ABSTRACT Mango (Mangifera indica L.) and Banana (Musa acuminata L.) are important tropical fruits ripen quickly and have a short postharvest life and commercialization window. In Mozambique, about 40 % of these fruits have been lost. In order to recommend small and medium enterprises in post-harvest fruit preservation, there is a need to develop appropriate alternative techniques for the post-harvest handling of fruits. In this work, the extension of the shelf-life of fresh mango and bana...
ABSTRACT The uses of composite flour in bread making are becoming more important as people become health conscious and accept the role of functional foods globally. The effect of partial replacement of wheat with 10% to 40% plantain flour and the subsequent effect of 1% to 3% gum arabic addition on composite bread quality attributes was investigated. It was hypothesized that wheat- plantain flour physicochemical properties did not differ from the control (100% wheat); and that neither substit...
ABSTRACT Biopreservation systems in foods are of increasing interest in the food industry. It is the use of naturally occurring microorganisms and/or their inherent antibacterial compounds of defined quality and quantity to extend shelf life and to enhance the safety of foods. Bacteriocinogenic LAB and/or their isolated bacteriocins are considered safe additives, useful to control the frequent development of pathogens and spoilage microorganisms in foods. The spreading of bacterial antibiotic...
ABSTRACT Mozzarella cheese is prepared using milk from various herbivores. Mostly, it is prepared using milk from sheep, cow and goat. However, due to consumers‘ demand for healthier foods, cheese processors have been innovatively preparing unique cheeses. Mozzarella cheese is one of the preferred ingredients for use on pizza. Goat milk is a good source of protein and calcium, possessing unique characteristics with a high proportion of small milk fat globules that contain a higher concentr...
ABSTRACT In Kenya, most studies involving exotic dairy goats and their cross breeds with indigenous goats have majorly focused on milk yield, kidding and growth rates with little information on the technological performance of the milk from cross breeds. In this study milk from the Toggenburg and its cross breed with Galla goat was evaluated fortnightly for composition and its capability for mozzarella cheese making over a three months lactation period. Samples of milk were analyzed for compo...
ABSTRACT Despite the Nile perch contributing about 67% of Kenya’s total annual fish export earnings, no specific method exists for evaluating the freshness of the fish when landed and its shelf life when kept in ice. Currently the European Union (EU) sensory scheme is used in sensory evaluation of all commercial fish species available in the Kenyan fishery. This study was conducted to develop a suitable Quality Index Method scheme, that is specific for the Nile perch, using a set of select...
