The Impact

Edible oils produced and consumed in Burkina Faso often do not meet established standards. The objective of this study was to evaluate the total gossypol level of refined cottonseeds oils and the oxidation state of crude peanut oils and refined cottonseeds oils in Burkina Faso to determine the impact on consumer health. A total of 61 samples including crude peanut oils and refined cottonseeds oils were collected in Ouagadougou, Bobo Dioulasso and surrounding areas. Total Gossypol and p-Anisidine value were determined by spectrophotometry. Peroxide value, acid value, soap residual value and mineral oils were determined by chemical methods. Total oxidation (Totox) value was determined by mathematical prediction. Overall, Gossypol total average of cottonseeds oils analyzed in this study was 0.032%. The p-Anisidine value average was 1.80 for refined cottonseeds oils and 11.65 for crude peanut oils. The Totox averages were respectively 19.37 and 28.36 for refined cottonseeds and crude peanut oils. The average peroxide values for refined cottonseeds oils and peanut crude oils were 8.52 and 8.33 mEq O2/Kg, respectively (p<0.05). The average acid values were 0.27 and 1.95 mg KOH/g for refined cottonseeds oils and crude peanut oils, respectively (p<0.05). None of the oils showed any mineral oil trace. The average residual soap values were respectively 1.47 and 8.32 ppm for peanut oils and cottonseeds oils (p<0.05). The majority values determined conformed to the Codex Alimentarius standard despite some cases of non-compliance. It is essential to improve the processes of oils production and conservation in order to have quality oils to guarantee the health of the consumer.

Abstract Investigations into some unexploited oleaginous seeds is imperative to supplement existing ones and boost supply of vegetable oil (VO). This work determined the impact of pre-treatment on some quality attributes of VO expressed from Pentaclethra macrophylla kernels using an oil expeller. Pre-treatment variables include Moisture Content (Mc), Roasting Temperature (RT), and Roasting Time (Rt) while quality parameters include pH, Iron content (IC), Acid Value (Av), Peroxide Value (Pv) and Saponification value (Sv). Standard procedures were followed in determination of oil quality and values obtained were compared with acceptable levels for VO. Optimum condition (8%db, 11.7 min Rt and 59.3oC RT) gave 5.8 pH, 0.044 mg/kg IC, 2.3 mgKOH/g AV, and 7 ml/g PV. The oil quality attributes conforms to acceptable levels for edible oils and was influenced by pre-treatment. The models developed to predict the relationships between pre-treatment and quality attributes are valid (p < 0.05).

The Impact

The use of fossil fuels as energy sources has grown to significantly be likely to have a major environmental impact. Reduction of world oil reserves and increasing environmental concerns have prompted alternative is found and renewable source of energy called biodiesel. Biodiesel fuel from vegetable oil is considered as the best candidates for diesel fuel replacement in diesel engines because of its closer. Fuel prices are going up day by day in the world. Thus, the means and methods have been trying for years to get fuel alternative outcomes. This study investigated the effects of different storage periods used in quality biodiesel blends (B5, B10, B15) of waste cooking oil and diesel fuel under low temperature and the temperature of the environment. Biodiesel samples were stored in glass containers under indoor conditions, and outdoor conditions for 10 weeks in total. These samples were monitored on a weekly basis through the test properties. The experimental density, viscosity, acid value, water content and flash point discussed in detail. Biodiesel storage at low temperatures is suitable and more advantageous because the impact on the physical properties is minimal and beneficial to slow down the degradation of biodiesel and storage.

As one of the 10 most polluted rivers in the world, Citarum river pollution has become the world’s spotlight. The pollution that occurred along the Citarum River in West Java has been the concern of the local government. Pollution not only comes from a plant and household, but also from industries. In this study the authors use descriptive quantitative method, where researchers will describe and compare the existing variables to see the possibilities that arise. Variable used is the number of industries that exist and how the impact against BOD. Biochemical Oxygen Demand (BOD) is a measuring instrument that is widely used to see the quality of oxygen levels in the water. In this paper shows that there is a possibility if BOD increases if the number of industries increases.

The focus of the current study is analyze the impact of the use of ICT on the performance of Tunisian companies. These companies must be always fully aware of the importance of a practical valorization of ICTs that bring about socio-economic development. Thus, using ICTs on Tunisian companies’ performance has unquestionably remained a vital need. In fact, this study is carried out on a sample of 150 Tunisian companies operating in different business sectors. We chose the quantitative method. So, to test our conceptual model, we applied the exploratory factor analysis and then the structural equation methods. The empirical testing of hypotheses of this research led to partially confirm the influence of ICTs on the performance of Tunisian companies. In this regard, the companies surveyed are almost aware of the importance of the value of ICT, which implies an insufficient use of ICTs and an incomplete maturity of this field.
