Abstract

Investment in the food cold chain has been reportedly identified as a solution to extensive postharvest losses worldwide. However, cold chain investment in the Ugandan food value chain is largely unknown. This study located, characterised, and determined the efficacy of bulk cold storage facilities used in handling perishable agricultural food produce in the 16 city districts of Uganda. Only 9/16 city districts had bulk cold storage facilities, translating to a cold storage capacity of 4.5 m³ per 1,000 inhabitants. The private sector owned the highest proportion by volume (90.3%) of these facilities with the highest volume used for handling multiple perishable products (11,590 m³). Generally, temperature varied significantly from the respective set points in the facilities. Variations were observed for between 1/3 to 3/4 of the logged period above maximum allowable storage temperatures for the different products, showing efficacy lapses. These results indicate investment and management gaps and opportunities in this indelible sector in food value chain by both government and private sector players.

评估乌干达城市用于批量处理易腐农产品的冷藏能力{fr}{ffr}Évaluation de la capacité d'entreposage frigorifique utilisée pour la manutention en vrac de produitsoles agricoles périssables dans les villes ougandaises

据报道，对食品冷链的投资已被确定为解决全球广泛的收获后损失问题的一种方法。然而，乌干达食品价值链中的冷链投资在很大程度上还不为人知。这项研究对乌干达 16 个城市地区用于处理易腐农产品的散装冷藏设施进行了定位、特征描述和功效测定。16 个城市地区中只有 9 个拥有散装冷藏设施，即每千名居民的冷藏能力为 4.5 立方米。在这些设施中，私营部门拥有的数量比例最高（90.3%），用于处理多种易腐产品的数量最多（11,590 立方米）。一般来说，这些设施中的温度与各自的设定值相差很大。在超过不同产品最高允许储存温度的记录时间中，有 1/3 至 3/4 的时间段出现变化，显示出效率的缺失。这些结果表明，在食品价值链中这一不可磨灭的领域，政府和私营部门在投资和管理方面都存在差距和机遇。

期刊介绍： The International Journal of Refrigeration is published for the International Institute of Refrigeration (IIR) by Elsevier. It is essential reading for all those wishing to keep abreast of research and industrial news in refrigeration, air conditioning and associated fields. This is particularly important in these times of rapid introduction of alternative refrigerants and the emergence of new technology. The journal has published special issues on alternative refrigerants and novel topics in the field of boiling, condensation, heat pumps, food refrigeration, carbon dioxide, ammonia, hydrocarbons, magnetic refrigeration at room temperature, sorptive cooling, phase change materials and slurries, ejector technology, compressors, and solar cooling. As well as original research papers the International Journal of Refrigeration also includes review articles, papers presented at IIR conferences, short reports and letters describing preliminary results and experimental details, and letters to the Editor on recent areas of discussion and controversy. Other features include forthcoming events, conference reports and book reviews. Papers are published in either English or French with the IIR news section in both languages.
