The influence of regular market selling conditions and storage methods on β-carotene stability and retention were investigated in two different biofortified gari types. Freshly processed gari samples obtained from TMS 01/1412 and TMS 01/1371 respectively were exposed to 35-450C sunlight (ESL) and 60 watts electric bulb light (EEB); stored in black polyethylene bag (SPB) and air-tight aluminum container (SAC) respectively. The stability (using area under curve analysis) and retention (%) of β-carotene in all the experiments were monitored and compared over a period of 4 weeks. Results revealed that ESL had a huge negative influence on the stability and retention of β-carotene in the two biofortified gari types. Although EEB showed minimal but progressive negative influence, SAC followed by SPB showed the least negative influence on the nutrient stability. The overall retention of β-carotene in gari processed from TMS 01/1412 and TMS 01/1371 respectively were as follows: ESL (12.1%, 12.8%), EEB (58.5%, 47.5%), SPB (61.9%, 50.8%) and SAC (60.2%, 82.6%). SAC retained the most appreciable amount of the nutrient thus suggesting it as a better form of storage while ESL lost the largest amount of the nutrient thus portraying it a detrimental market selling condition for the biofortified gari.
