| dc.description.abstract | Reducing postharvest losses is a crucial step in increasing food availability. A recent study aimed to analyze the nutritional quality, postharvest loss extent, causes, and seed quality of emmer wheat. The research was conducted in 3 stages. The first stage involved collecting seeds of four varieties of emmer wheat (Sinana 01, Lameso, Hydaroo, and local landrace) grown in two growing seasons and analyzing their nutritional, physical, functional, and microstructural properties. The second stage aimed to determine the postharvest loss and causes for the losses. A semi-structured survey questionnaire was used to collect primary data from a total of 370-emmer wheat producing farmers of Goba, Sinana, and Ginir woredas and 20 traders in the Bale zone from the main market. Whereas FAO‟s 4s (screening of relevant data, surveying, sampling (load tracking), and synthesis) method was used to determine losses in the selected value chain of emmer wheat at the farmers‟ level. For the third study postharvest storage methods viz. (1) Polypropylene bags (2) Purdue Improved Crop Storage (PICS) bags, (3) Super Grain Pro bags and (4) Polypropylene bags treated with filter cake and triplex powders were used for storage of seeds for nine months. The results showed that seasonal variation, grain types, and varieties have a great effect on the proximate, physical, and functional properties of emmer wheat cultivated in Ethiopia. The load tracking result indicated that harvesting (3.75%), transportation to a threshing field (0.17%), and threshing (2.96%) were identified as critical loss points. The powders such as xvii filter cake and triplex showed a comparative effect with hermetic storage bags in maintaining the seed and nutritional quality of emmer wheat. Future work should focus on the application of studied methods. Keywords: Supply chain, Germination, proximate composition, Hermetic storage, Ethiopia, load tracking. | en_US |
