ABSTRACT This study assessed changes in chemical components of the sun dried and hot smoked anchovies processed by traditional and improved methods. Except for the protein-bioavailability analysis which took place once during the fourth week, the samples of fish were assessed weekly. Nutrient composition, shelf-life and protein-bioavailability of processed anchovies were assessed using changes in proximate composition and specific minerals, biochemical indices and protein-digestibility, respe...
ABSTRACT Assessment of Uranium levels in selected food groups and products with the associated health effects to the residents of Bahi District was carried out. The objective was to come up with information on whether these food groups contain significant amounts of Uranium and if the community has been affected by uranium related diseases. This was done to bring the awareness to the vulnerable communities and Tanzanian Government in general on the environmental and health hazards posed by th...
ABSTRACT Begomoviruses are whitefly-transmitted viruses belonging to the family Geminiviridae presenting most devastating threat to food security. This study was initiated to asses cassava mosaic disease (CMD) severity and genetic diversity of DNA-B component of East African cassava mosaic viruses (CMD) that infect cassava plants from main cassava growing regions in Tanzania. The study involved field survey, rolling cycle amplification (RCA) followed by next generation sequencing (NGS). The s...
ABSTRACT “Mamung’unya” (Benincasa hispida) is a seasonal fruit widely grown in Dodoma region.

ABSTRACT Foot-and-mouth disease (FMD) is a highly contagious disease of cloven hooved animals that continues to occur in Ngamiland District of Botswana although stringent disease control measures have been put in place. This may be due to irrelevance of currently used vaccine strains. In the present study, genetic and antigenic characteristics of SAT2 viruses isolated from outbreaks which occurred in 2011 and 2015 in Ngamiland districtwere examinedin order to determine any mutational changes ...
ABSTRACT This study was conducted to investigate the effectiveness of natural and synthetic materials as adsorbents for hard water treatment by using EDTA titrimetric method. Natural adsorbent prepared from cactus and synthetic adsorbent prepared by grafting potato starch and the study conducted on water samples collected from Nzuguni, Ng’ohong’hona, Kisasa and Swaswa in Dodoma municipality. The results revealed that the concentration of hardness decreased as the dose of (Cactus Materia...
ABSTRACT The purpose of this study was to develop buns (Mandazi) based on wheat and jackfruit seeds flour and assess their chemical composition, sensory profile and consumer acceptability. Samples of jackfruit seeds were obtained from Tanga, Morogoro, Coast region and Zanzibar. Seeds were sorted, washed, pre-dried, seed coat peeled, sliced, dried and milled to flour. The developed jackfruit seed j flour from each location was blended with wheat flour at different levels of substitution (10%, ...

ABSTRACT Innovations in ICT continue to transform business processes in ways never imagined before. When organisations take full utility of available technologies, business processes become more efficient while service delivery improves. Ultimately this bridges gaps between inter organisational relationships by making information sharing easier and more secure. This is crucial in the tourism sector where information is the lifeblood of the sector. The study sought to develop an ICT based fram...
ABSTRACT This study was conducted to isolate, characterize, thermostabilize and develop an easier and cheap technique for preparation of inactivated and live vaccines against Infectious coryza (IC). Fifty six (56) samples were collected from chicken. Fourty eight percent (27) isolates had phenotypic characteristics suggestive of both pathogenic and non pathogenic Avibacterium species. Fifty nine percent (16) of 27 isolates were catalase negative, oxidase positive and NAD dependent. Moreover, ...
ABSTRACT Mango and tomato are widely grown in the World. The present study was carried out to compare the effectiveness of three preservatives in retaining their quality attributes of mango and tomato and substituting the use of sodium metabisulphite with either the lemon juice or acetic acid. The three preservatives were sodium metabisulphite (0.1%), acetic acid (0.5%) and lemon juice (0.5v/v) studied at the respective level in bracket. Mango and tomato slices were dried in the walk - in sol...
