Abstract/Overview This study aimed at generating knowledge on the nutritional composition and sensory evaluation of biscuits fortified with sorghum flour and cricket powder. Four biscuits samples were formulated by substituting wheat flour with sorghum flour and cricket powder at 0, 20, 40, and 60%. The results showed that, the fortification improved some nutrient contents of biscuits significantly (p
Abstract/Overview The motivation of consuming edible insects, particularly lake flies, has the potential of improving the problem that results from the inability to sustainably meet the rising demand for animal-based protein as a result of increased population growth and urbanization. The aim of this study was to identify the selected socio-economic factors influencing consumption of lake flies and how they individually and collectively affect the consumption. A sample size of 385 respond...
Abstract/Overview Technical efficiency measures the effectiveness of an enterprise given the available resources at disposal and how well it transforms these resources to get maximum output. This study therefore investigated the technical efficiency of cricket, A. domesticus and G. bimaculatus, production at JOOUST cricket farm using parametric approach. Stochastic frontier analysis was used to analyze the data collected from the farm between 2015-2017. Maximum likelihood estimates result...
Abstract/Overview Food security is a major global concern. It has insidious effects on the health and development of young children and consequently, adults. The paper assesses the food security status and its key determinants for the rural households of the high rainfall zone (HRZ) of Murang’a, semi–arid lands (SALs) of Kitui and arid lands (ALs) of Isiolo in Kenya. A three stage sampling technique was used for respondents (384) selection. Data collected were: demographics, livelihoo...
ABSTRACT Freshly extracted juices obtained from organically and conventionally produced orange and apple fruits were assayed in terms of their nutritional quality. Parameters used in the assessment were total soluble sugars, ascorbic acid content, folic acid concentration, acidity, glucose, fructose, maltose and sucrose contents, as well as the concentrations of sodium, potassium, calcium, iron, zinc and copper. Total and individual sugars were detected using HPLC while brix concentrations we...
Abstract: One of the major global concerns historically and in the twenty-first century is providing sufficient, safe and nutritious food to all people. New, existing and emerging technologies can help address the issue of food security in the East Africa region. This research examines the significance of innovation and technology in transforming the food systems in East Africa. Achieving hunger and improved food systems by 2030 according to the new sustainable development goals, will requir...
Abstract: The consumption of pumpkin seeds in oil form or roasted pumpkin seeds has been is proved to exhibit several positive health effects. The aim of the present study was to examine the physicochemical properties, antioxidant and antimicrobial activities of pumpkin (Cucurbit sp.) Seed and pulp oils. The oil extraction was done in Soxhlet apparatus using hexane as a solvent. Then, physicochemical properties of the oil extracts were determined based on determination of oil content, specif...
Abstract: This study was aimed to investigate the shelf-life and rheological properties of cottage cheese made from camel milk as physicochemical properties, microbial counts and texture. The experiment was laid out in completely randomized design (CRD) with eight treatments. The general chemical composition of milk including fat, solids-not-fat (SNF), protein, total solid, casein and lactose were determined using MilkoScan. Cheeses were made in the dairy technology laboratory of Haramaya Un...
Abstract: Due to its extensive use in the food and pharmaceutical industries, citric acid is an essential organic acid that is in high demand around the world. To meet this increasing demand, an effort has been made to use inexpensive agro-industrial waste products as carbohydrate sources for the production of citric acid using Aspergillus niger. Therefore, the present study was performed to produce citric acid from avocado (Persea americana) peels as a novel substrate through solid state fe...
Abstract: Climate change has serious consequences for food production of smallholder farmers in poor countries including Ethiopia. Farmers exercise various adaptation strategies to counter the negative impacts of climate change, but the level of participation and impact of adoption of adaptation practices against climate change on food security has not been the focus of scientific studies. Therefore, the obj ective of this study was to assess farmers’ participation in climate change adapta...
Abstract: The present study was carried out at Haramaya University dairy laboratory with the intention of investigating (1) the effect of camel chymosin on milk coagulation properties of camel milk and (2) the effect of camel chymosin and cooking on soft unripened cheese characteristics. Two experiments were conducted. The first experiment was on milk coagulation with completely randomized design (CRD) and different chymosin concentrations (40, 70 and 100 IMCU/L) were tested for gelation tim...
Abstract: The current study was conducted at Haramaya University Dairy laboratory with the main objective of investigating how heat treatment affects whey proteins and rennetability property of camel milk for cheese making. Completely randomized design (CRD)was used by evaluating effect temperature (heated at 400C,650C/30min,720C/30 sec, 750C/5 min, 850C/5 min and 900C/5 min).Unheated milk used for alternative reference during chemical and whey protein denaturation evaluation. Similar experi...
Abstract: The objective of the study was to assess hygienic production practices, microbial quality and marketing of raw cows’ milk and milk products. The study was conducted on survey work and laboratory analysis. The survey works involved interview of 180 smallholder milk producers from two agro ecologies in the district while 40 milk samples were collected in the morning from milk producers, small shops, cafes and consumers for laboratory analysis. Majority of the respondents (96.7%) di...
Abstract: This dissertation was composed of four experiments. In the first experiment, effects of different processing methods(roasting, boiling and germination) on proximate composition, some mineral and antinutrient contents of finger millet was evaluated. In the second and third experiments, the replacement effect of roasted finger millet grain for maize in starter and finisher broiler diets on feed intake, body weight, blood hematology, carcass parameters and meat chemical composition we...
Abstract: Sensory quality and physicochemical properties are very important to determine yoghurt quality. Sensory attributes of yoghurt can be affected by starter cultures and pasteurization temperature in yoghurt manufacturing process. This study was aimed to investigate effect of three commercial starter cultures namely YoFlex Mild 1.0 and YF-L904 (thermophilic yoghurt cultures containing strains of Lactobacillus delbrueckii subsp. bulgaricus and Streptococcus thermophiles) and RST-743(Lac...
