ABSTRACT This study was conducted to assess compliance to fortification of sunflower oil and palm olein with retinyl palmitate. Fortified sunflower oil and palm olein samples were collected from large scale edible oil manufacturers and at selling outlets in Dar es Salaam region. Mean retinyl palmitate levels in fortified sunflower oil samples from manufacturer A collected at production site and at selling outlets was 12.42 and 10.19 mg/kg, respectively. In fortified palm olein samples levels ...
ABSTRACT Small and Medium Scale Enterprises (SMEs) processing fruits play an important role in the national economic development of Rwanda. Although these SMEs have received assistance from the government, they still face many constraints that hinder their development. For example, their access to both local and export markets is limited due to poor quality of their products. A study was conducted using a cross-sectional study design, to assess the compliance of the food SMEs with national an...
ABSTRACT Information on the nutritional content and health-promoting properties of African indigenous fruits is very limited. Although the limited available literature does point towards wealth in essential nutrients, micronutrients and antioxidants there is still a need to fill the gap to ascertain health and nutritional claims that have been passed on from previous generations. Studies on the impact of processing of the fruit pulp on physicochemical, nutritional properties, and digestibilit...
ABSTRACT “Mamung’unya” (Benincasa hispida) is a seasonal fruit widely grown in Dodoma region. To distribute its availability throughout the year, there is a need to test different drying methods for preservation. The present study was carried out to assess the effect of drying methods on nutrient content and sensory acceptability of processed products from selected Benincasa hispida varieties available in Dodoma region. A total of 120 farmers were interviewed using a structured question...
ABSTRACT This study determine effectiveness of tomato postharvest processing technologies by boiling and solar drying for small scale processing based on nutritional and sensory quality. Tomato sample varieties Asira, Imara and Reogrande were collected from small scale farmers in Morogoro region for tomato paste and powder development. Nutritional quality was determined based on moisture, lycopene, ß-carotene and ascorbic acid contents, titratable acidity and pH. Sensory properties were dete...
ABSTRACT Minced meat is a nutritionally dense and highly perishable food, therefore there is need for preserving it. Most artificial preservatives currently used to prevent food spoilage have been reported to cause various health problems hence the need to use natural preservatives. Moringa oleifera and Brassica oleracea (broccoli) leaf extracts have proved their potential to be used as natural preservatives. The main objective of this research was to determine the antimicrobial efficacy of M...
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 To increase the brewing yield and efficiency, malts with high extract values, high enzymatic activities, and good modification are essential. To produce malt that meets these requirements, the barley employed must have minimal post-harvest dormancy and be able to germinate rapidly and uniformly. The aims of this study were to compare the changes in seed germination vigour trends and the general storage stability of two Zimbabwean two-row malting barley varieties (Hope and Sierra) as ...
ABSTRACT Quality deterioration of Lake Victoria sardines is one of the most common claims from the final consumers which causes the change of use from human food to animal feed. Evaluation of post-harvest loses of Lake Victoria sardine was done by using three different methods, which are chemical laboratory analysis, microbial analysis and sensory evaluation. In this study it was shown by significant increase in total bacteria count seen from all samples taken along the steps of the value cha...
ABSTRACT Underutilized indigenous vegetables from Morogoro and Kilimanjaro regions were investigated. Out of these, four underutilized vegetables (UVs); Sunga (Launea cornuta), Kikundembala (Vigna vexillata), Mokiki (Momordica foetida) and Inyiri (Basella alba) were identified, collected and studied. The overall objective was to identify and analyze safety and nutritional excellence of the identified UVs used as food and claimed to be remedy to the sick. Primary data was collected using a che...
ABSTRACT The aim of the research was to determine the occurrence of antibiotic residues in milk in Gweru. The population consisted of twenty-eight farmers. Ten farmers were randomly selected from the population. The average volume that the farmers supply to dairy processing companies was twenty thousand liters during the time of sampling. Raw milk was sampled in two hundred and fifty mls sterile sample bottles. The samples were frozen up to the time of analysis. Detection and quantitation of ...
