“…The most important criteria for farmers to select a cultivar were high yield and availability of low-cost planting material; these findings are similar to previous studies which reported yield, drought tolerance and early maturing as some of the important cassava cultivar selection criteria for farmers in the region (Mulualem and Dagne 2015). Previous reports on the toxicity (cyano-glycoside content) of Qulle and Kelle cultivars from Ethiopia showed a cyanide content of 69 and 50 mg/kg in fresh peeled root, respectively, which may be reduced to below detection levels after processing into flour and the final preparation of fermented flatbread injera (Nebiyu and Getachew 2011; Kebede et al 2012). No incident of acute or chronic cyanide toxicity due to cassava consumption was reported from the study area during the survey.…”

Improved (high yield and disease resistant) cassava varieties were introduced into Ethiopia around the onset of the twenty-first century, as a potential food security crop. At present, limited information is available from the country on post-production aspects of the value chain (VC) and related food losses. The lack of such data prevents policymakers and VC actors from taking steps towards improving VC efficiencies, which can have a significant impact on livelihoods and food security. The focus of this study was to examine the prevailing post-harvest practices in the cassava VC in southern Ethiopia and quantify the extent of food losses and associated by-products in the framework of the recently developed 'food loss and waste protocol'. The majority of the cassava in the study area was processed into dry chips and milled into a composite flour with teff and maize to prepare the staple bread (injera). 'Critical loss points' were during sun-drying (4%) and stockpiling at farm and marketplace (30-50%). Insect pest damage was primarily responsible for food losses at farm and market level. The most important insect species infesting dry cassava were identified during the survey. As far as the by-products were concerned, the ratio of leaf:wood (stem and stump):starchy root on a dry matter basis at harvest was 1:6:10. Further emphasis should be on improving processing and storage technologies to reduce food losses and the better recovery and utilisation of by-products, especially the leaves of cassava, which could be a potential source of protein in human diets.

“…In the present study, the mean glycemic response value of the cassava with respect of time interval was 70. Cassava is one of the largest source of carbohydrate and consumed by peoples of many countries in the world, despite of lower in protein and fat content when compared to the rice and potatoes [7]. The blood glucose response of the cassava had lower than the reference food of white bread.…”

“…The potato, sweet potatoes and taro cover 25.2%, 38.11% and 19.72% of the total root crop area respectively and these crops contributed about 23.35%, 38.44% and 17.74% of the total root crop production respectively in the Ethiopia [6]. Cassava (Manihotesculenta Crantz) is an important root crop staple food for many countries including an Ethiopia [7]. Cassava is rich in carbohydrates, calcium, vitamins B and C and essential minerals and inferior in protein and fat content, so that the soybeans are often used to balance the diet in cassava consuming area [8].…”

Introduction:Glycemic index is an important parameter designed to quantify the relative blood glucose response of foods in comparison with reference glucose. Determination of glycemic index and loads of carbohydrate-rich foods play as tools of nutritional guidelines for glycemic control and to reduce the risk of diabetic complications. Thus, the aim of this study was to determine glycemic Abiche et al.; IJBCRR, 26(4): 1-12, 2019; Article no.IJBCRR.49454 2 index and glycemic loads of cassava and sweet potato of commonly consumed food items of Bench-Maji, south west Ethiopia. Materials and Methods: The 23 healthy subjects were participated in the study from Ethiopia; the mean age was 27 ± 2 years. The matured cassava and sweet potato food items were processed by washed, peeled and cooked in water (gentle boiling at 90 C o ) for 20 minutes. Participants were informed to consume 50 g of carbohydrate portions of tested and reference foods. Blood sample were collected at 0 (fasting), 30, 60 and 120 minutes after ingestion of tested and reference foods. Glycemic index value of foods was calculated from the ratio of incremental area under the glucose curves of the foods. Glycemic loads for each food was determined from its glycemic index value and carbohydrate content. Data were statistically analysed by ANOVA and differences between means identified by the student t-test. Results: The cassava and sweet potato had a medium glycemic indices (GI: 60), in spite of they generated a high glycemic loads of 26 and 24 respectively. The cassava and sweet potato had significantly lower (p<0.0001) blood glucose response was noticed as compared to white bread. There was no difference of GI and GL of tested foods within the participants and statistically not significant (p>0.05). Original Research Article Conclusion:This study showed that the cassava and sweet potato foods had a medium glycemic index and high glycemic loads. The tested foods had significantly lower blood glucose response as compared to reference food of white bread. The resulted GI and GL data of tested foods could be help as guide of food choices to control glycemic level and to reduce the risk of diabetic complications.

“…However, the subsistence status of this crop species is rapidly changing to a cash crop with its enhanced usage in multiple industrial applications such as the production of paper, textile, plywood, glue, biofuel, animal feed and beverage. Cassava in Ethiopia is relatively new, it was introduced in 1960, but its importance dramatically increased in the country after the famine of 1984 ( Kebede et al 2012 ). Presently, it is an important crop in the south and south-western parts of Ethiopia where the local population tends to rely more on root crops.…”

Boxwood BorerHeterobostrychus brunneus(Coleoptera: Bostrichidae) Infesting Dried Cassava: A Current Record from Southern Ethiopia

et al. 2017

View full text Add to dashboard Cite

Insect specimens of adult beetles and larvae of 7–9 and 9–10 mm length, respectively were collected from infested dry cassava at two locations from multiple stores in southern Ethiopia. The specimens were identified as Heterobostrychus brunneus (Murray, 1867) commonly known as boxwood borer and auger beetle. The study presents a current record of H. brunneus in Ethiopia, particularly in the context of infesting food products. Additionally, a wide geographical distribution of the pest was reviewed and presented in this article. Current evidence suggests that H. brunneus is a serious pest of forest wood, structural timbers, and dried food products and that it carries a risk to be introduced into various other parts of the world via global trade.
