| Abstract | This study was carried out the investigate the effect of different stem diameter on qualities of asparagus in MA storage and conventional storage (packed with perforated film). Asparagus were sorted by stem diameter, such as 10 mm and 15 mm and then stored at 4℃ for 40 days. Fresh weight loss rate was 3-4% in conventional storage and under 0.3% in MA storage regardless of stem diameter. Carbon dioxide contents within a package maintained 5-12%. Oxygen contents were more than 5%. Ethylene contents were quickly increased after one day of storage and then dropped down to the final storage day. Gas compositions within a package did not shown any significant differences between asparagus stem diameter. Visual quality in MA storage had higher value than conventional storage and 10 mm stem diameter of conventional storage was shown the lowest value. Off-flavor had shown the better result in MA storage regardless of stem diameter, because fungi and decay occurred during the late period of storage. Firmness was higher in MA storage than conventional storage and 15 mm stem diameter showed higher than 10 mm in MA storage. Soluble solid contents were highest the 15 mm conventional storage. Hue angle value was higher the 10 mm MA storage than others and MA storage had higher value then conventional storage. The results were indicated that the 15 mm stem diameter of asparagus was suitable for conventional storage, although the stem diameter of asparagus did not have a significant effect on storability in MA storage. |
