| Abstract | Oxygen transmission rate (OTR) films of 1,300 and 10,000 cc/m2/day/atm, perforated (P), microperforated (MP), and vacuum (V) films were investigated for suitability in maintaining the quality and prolonging shelf life of asparagus during cold storage. An additional investigation using 60% (v/v) carbon dioxide treatment (V + 60% CO2) was also performed. All samples lost fresh weight over time, P and V + 60% CO2 had the highest and lowest fresh weight loss rate by the last day. Only 1,300 cc and 10,000 cc OTR films kept the asparagus at a marketable value, the least off-odor was detected in P, and the worst was in V + 60% CO2 in final day. The V + 60% CO2 resulted in lower firmness in asparagus tips, and the V resulted in the lowest firmness in stems. Although, little color changes happened in all treatments, the V + 60% CO2 treatment had greater soluble solids content and hue angle. The highest ethylene concentration was detected in the V film. The CO2 and O2 levels of the 1,300 cc and 10,000 cc OTR treatments were more suitable for asparagus storage. In general, based on the visual quality, 1,300 cc and 10,000 cc OTR films were more effective for asparagus cold storage. To some extent, high CO2 treatment exhibited a positive effect on maintaining internal quality, fresh weight and color of asparagus. |
