Abstract
|
|
|
Viking variety was stored in normal atmosphere(NA) and controlled atmosphere (CA) at 35°F. CA with 6.2% CO₂ and 2.3% O₂, was maintained during storage test by a Tectrol generator.
Asparagus stored in CA had significantly less bacterial soft rot than that stored in HA. Shear force measured at 7.5 inches from tip increased as storage period was extended. There was no effect of CA on shear force of stored asparagus. Increase of fiber content in asparagus during storage was significantly retarded by controlled atmosphere storage. "Butts standing in water" stored in CA decreared fiber content during storage.
Asparagus stored in CA had higher chlorophyll content than that in NA. Reflectance color values stored on the Fermentative Production of Guanos Ine-5´-monophosphate by Mlc roorganis m s of stored asparagus, L, √a²+b², and ΔE were very closely associated with chlorophyll content in asparagus. L, √a²+b², and ΔE increased as chlorophyll content in asparagus decreased.
"Butts standing in water" stored in CA was found to be the best method to maintain overall quality of harvested asparagus for extended period of time.
