ABSTRACT: Cold storage is expensive for smallholder farmers and seed processors in developing countries. Smallholder farmers continue to resort to traditional storage methods such as polypropylene (PP) bags for maize grain storage. They often dose the grains with chemicals to preserve them. However, hermetic bags have proven to provide superior protection to grains during storage without chemical treatment. With the advent of the COVID-19 virus which distorted many food systems across continents, stakeholders in the grain industry need to adopt better systems to reduce post-harvest food loss and improve food security. In this study, maize grain quality, nutritional content and viability were compared under three storage methods (PP bags with Phostoxin treatment, cold storage, and hermetic bag) over a storage period of four months. The results showed that the hermetic bag maintained the moisture content (MC) of the stored grains with 0.40% variations from the initial MC of 13% at the end of the storage period compared to 0.70% and 1.10% for grains stored under cold storage and in PP bags, respectively. Grain damage after the 4th month of storage in the hermetic bag had only increased by 0.40% from an initial 13.3% before storage compared to an increase of 6% for cold storage, which was attributed to unstable power during the storage period, and 4.30% for grains stored in the PP bag. Carbon dioxide concentration in the hermetic bag was maintained at about 11% throughout the storage period indicating low microbial activity. The hermetic bag technology was identified as the best option for quality preservation during storage of maize grain over the other methods, and its adoption by smallholder farmers in Ghana should be considered. |
