Dehydration is widely used to preserve dark green leafy vegetables (DGLV) but storage in normal atmosphere condition losses beta-carotene by oxidation, therefore requiring use of an oxygen absorber. The study examined use of kitchen steel wool as an oxygen absorber in reducing the loss of beta-carotene content in three indigenous DGLVs that were solar dried and stored for a period of 168 days in four different packing conditions. Fresh vegetables contained between 781.94 to 1047.42 μg/g dry matter (DM) beta-carotene, reducing significantly (p=0.01) to between 653.63 to 712.99 μg/g DM after dehydration. Steel wool oxygen absorber significantly improved (p = 0.02) beta-carotene retention, recording a loss of 19.5 to 37.6% compared to 47 to 72% in normal conditions. Storage of DGLVs under kitchen steel wool oxygen absorber preserves vegetables and retains high levels of beta-carotene.enDark green leafy vegetablesbeta-caroteneoxygen absorberskitchen steel woolsolar dryingArticle
