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...

Quality Characteristics Of Palm Oils Produced From Improved Traditional, Artisanal, Medium And Large Scale Processes

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...

Effects Of Extrusion Processing On The Physico-Chemical And Nutritional Characteristics Of Fish Feeds Containing Acheta Domesticus And Hermetia Illucens Meals

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 ...

Analysis Of Microbial Infections In Camel (Camelus Dromedarius) Milk And Implications In Kenya

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.

Effects Of Gum Arabic Surface Treatment On Nutritional Quality Of Whole Mango (Mangifera Indica) In Makueni County And Evaluation Of Canned Mango Chunks

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...

Optimization Of Brewing, Processing Conditions And Their Effects On The Chemical And Sensory Quality Of Purple-leafed Kenyan Tea

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...

Chemical And Sensory Quality Evaluation Of Newly Developed Tea Clones In Kenya

A study was conducted on the newly developed purple tea clones in Kenya.
