| Abstract | Snap bean (Phaseolus vulgaris L.) is a major vegetable export crop in Kenya as well as local consumption. The market is dynamic and hence the need to introduce new varieties to meet market requirements. The introduction of new snap bean varieties requires evaluation of their post-harvest quality in order to ascertain optimum handling procedures for the local producers. A preliminary study was conducted where mature snap beans of samantha variety, were collected from small holder farmers in 2 growing seasons and data was collected with a view to developing a model for short term storage for prediction of the relationship between storage conditions, physical and nutritional quality under low density polythene bags. Half of the samples were packed separately in open polythene bags while the other half was packed in closed polythene bags and stored at 5 o C, 10 o C, 15 o C and 25 o C and observations made for 9 days. It was observed that the higher the temperature, the higher the weight loss although the loss was higher in open polythene bags in all the storage temperatures. Similar trends were also observed in the loss of chlorophyll in both samples with samples stored at 25 o C showing 5.5mg/L of chlorophyll content at day 9. There was a higher loss in total soluble solids in the samples stored in open polythene bags at 25 o C with the samples showing 5.3% by day 9. There was a slower loss of vitamin C in samples stored in closed bags; however, the samples stored at 25 o C for both treatments had the greatest loss by day 9. The results show that packaging |
