Snap beans packed in low density polyolefin film and stored at 5°C and 10°C were removed at days 0, 4, 8, 12, and 16 for quality evaluation. Chlorophyll content of beans stored at 5°C was not influenced by storage period. Pods stored at 10°C showed significant increase in chlorophyll after 4 days storage followed by a decline as time of storage increased. Hue angle and tristimulus a* corresponded more closely to chlorophyll content and were better indicators of snap bean color than chroma and tristimulus L* and b*. Weight loss, seed percentage and ascorbic acid were higher in pods stored at 10°C than in those stored at 5°C. Storage temperature and period had no influence on texture or soluble solids content.
