    Objective In the present study, an effort has been performed to determine trans fatty acid, free fatty acid, and cholesterol content of some selected edible oils in Ethiopia. Five brands of locally made different edible oil samples were purchased from super markets of Ethiopia. The quality of these edible oils was analyzed by evaluating their chemical properties such as acid, saponification and peroxide values using standard methods (titrimetric technique). Results The results of the study revealed that maximum and minimum acid value was 5.59 ± 0.02 mg/g for Beksa (Niger oil) and 0.11 ± 0.02 mg/g for Tena (sunflower) oil respectively. Similarly, the saponification value showed (223.2 ± 0.39 mg/kg) for Tena and (173.4 ± 0.46 mg/kg) for Beksa. The maximum peroxide value was observed in Lulu (vegetable oil; 11.67 ± 0.11 meq O2/kg) and minimum value found in Sunny (sunflower oil; 2.84 ± 0.05 meq O2/kg). The highest total free fatty acid as oleic acid was observed in Beksa (2.95 ± 0.03%)...

    Honey is one of the agricultural products produced for different purposes as a food, and condiment, and has medicinal value. The quality and safety of honey supplied to the market are in question due to mishandling practices and suspected adulteration for unfair economic gain. This study aimed to assess honey handling practices along the supply chain from the Gera district to the main market destination (Jimma town) in the southwest part of Ethiopia. Information was gathered from a total of 292 sampled members of different chain actors (262 beekeeper households, 5 beekeeper cooperatives, and 25 retailers). Data on handling practices affecting quality and safety were collected through observation and interviews using pretested semi-structured questionnaires and focus group discussions. Most of the beekeeper households (88%) do not store many portions of harvested honey for more than six months; whereas, the majority of cooperative beekeepers (80%) store from 6 months to one year. In ...

    This review paper was prepared by reviewing and summarizing several findings including research articles, FAO, and WHO databases concerning the pandemic and related issues. The security and safety status of foods during the pandemic outbreak and the possible solutions to food-related problems were also reviewed. The COVID-19 pandemic is currently not only affecting health but also the security of foods and nutrition. The effect of the Covid-19 on the entire food along the value chains was reviewed in this paper. The Coronavirus has been disturbing the health of world populations and food security. It is critically affecting the food processing business in various ways. The mitigating measures taken to contain the virus and decrease transmission to society are directly and indirectly affecting food security and safety. The overall food system is being disturbed by movement restrictions, closure of borders, and quarantine in turn resulting in low availability of food and an increase i...

    This review paper was prepared by reviewing and summarizing several fi ndings including research articles, FAO, and WHO databases concerning the pandemic and related issues. The security and safety status of foods during the pandemic outbreak and the possible solutions to food-related problems were also reviewed. The COVID-19 pandemic is currently not only affecting health but also the security of foods and nutrition. The effect of the Covid-19 on the entire food along the value chains was reviewed in this paper. The Coronavirus has been disturbing the health of world populations and food security. It is critically affecting the food processing business in various ways. The mitigating measures taken to contain the virus and decrease transmission to society are directly and indirectly affecting food security and safety. The overall food system is being disturbed by movement restrictions, closure of borders, and quarantine in turn resulting in low availability of food and an increase in the price of food products. The effect of the pandemic on food security can be estimated based on the impacts the previous pandemic Ebola made on the DRC and Liberia in 2014. The effects of the pandemic on the food production system and availability are similar. The mitigating measures suggested like movement restrictions, social distancing, and border closing and quarantine to protect the people from the COVID-19 are affecting global food security at large. Keeping the movement of foods along the value chain is crucial to creating and maintaining the confi dence of consumers in the availability and safety of foods. Both security and the safety of foods are important things to be considered throughout the pandemic era. The important issue is that the low access to food and increase in price is challenging because; the pandemic affects labour for production at the farm, food processing personnel, marketing, and all the supply chains from production up to fork.

    One of the main challenges facing Ethiopia today is to ensure food security for its highly increasing population growth. Although the country's production is much lower than the national demand, there are high post-harvest food losses. Among several causes at different levels, absence of infrastructure plays a critical role in quantitative and qualitative losses of mainly fruit, vegetable, root and tuber crops. This study was initiated to investigate impact of two different production areas having different road access on qualitative and quantitative loss of potato tuber in extended storage time. Load tracking approach was used by simulating existing postharvest handling and storage practice of potato tuber in the study area. Quantitative post-harvest loss assessment along the supply chains, qualitative loss and shelf life estimation at retail market were investigated using standard methods. Results showed that more mechanical damages and seepage loss were observed in case of poor road quality and transportation. During extended storage time (30 days) at ambient environment, potato tubers transported from Dedo to Jimma resulted in high average weight loss (17.9 AE 0.9%), significant loss in firmness (7.0 AE 0.6N in average) and average vitamin C content of 9.20 AE 0.05mg/100g as compared to tubers transported from Seka to Jimma market. This implies that, lack of good road access and transportation facility contributed for more external mechanical damages and internal injuries which will critically enhance rate of degradation of tubers in later stages of storage.
