    Combining thermization and evaporative cooling toward milk freshness preservation at the smallholder farm level
    (Journal of Food Process Engineering, 2020) Sempiira, Edison J.; Mugisa, Dana J.; Galiwango, Joseph; Kisaalita, William S.
    Thermization and low‐cost evaporative cooling have been seamlessly combined (evakuuling process) to preserve milk freshness for next day market. For proper regulation, a more exact profile of thermized milk in the hands of smallholders is needed. The purpose of this paper was to establish the milk quality‐profile of “evakuuled” milk. Thermization was done using temperatures between 55 and 70°C. Evakuuled milk quality‐profile (total viable and psychotrophic microbial counts, fat, protein, and pH) was compared to chilled and fresh milk. A consumer sensory test was also performed to evaluate consumer preference. The results showed that the quality‐profile of milk thermized at 65°C, followed by evaporative cooling (evakuuled) was indistinguishable from chilled and fresh milk. A consumer preference test scored evakuuled, fresh and chilled milks on average equal in terms of taste, appearance, aroma, and general acceptability. Practical applications The finding of evakuuled milk having the same quality attributes as fresh or chilled milk and meeting consumer preference in terms of aroma, taste appearance and general acceptability has potential practical significance. These results provide evidence in support of inclusion of evakuuled milk in the East African raw milk standard.

    Cultural Influences in Women-Friendly Labor- Saving Hand Tool Designs :
    (Human Factors, 2016) Kisaalita, William S.; Katimbo, Abia; Sempiira, Edison J.; Mugisa, Dana J.
    One of the reasons behind the gender asset gap among Sub-Saharan African women is the higher labor burden these women face, making it difficult for them to produce for the home and markets. Hand tools are the simplest form and therefore the best first step to address this problem. But designing women-friendly (sustainable) hand tools calls for better understanding of the low-resource settings where these women reside.

    Development of Pictograms to Communicate Technological Solution Instructions (Labeling) Among Low- Literacy Users
    (Ergonomics in Design, 2022) Kisaalita, William S.; Sempiira, Edison J.
    Conveying information for appropriate use of devices is uniquely challenging in low-resource settings. Drug makers have previously developed culturally meaningful informational pictograms to, for example, convey timing of doses, among low-literacy patients. We tested a similarly structured process among Ugandan smallholder farmers. Over 67% of the pictograms scored a passing grade after the second round of testing, meeting our overall success criterion. The process is efficacious in developing instructional/teaching (labeling) pictograms. These findings can help solution/device developers for low-resource settings to provide correctly interpretable pictograms and thus eliminate misuse-driven low uptake.
