Summary
Freshly harvested white asparagus spears were over-wrapped with a 16-micrometer stretch film. Packages were kept at 2.5, 5, 10, 15, 20 and 25 °C in continuous darkness or light (15 plus or minus 1.9 W/m2) for 6 days. At all temperatures, an atmosphere of 4.5-6.9% CO2 and 3-6.7% O2 developed during the first hour; after 8 h, CO2 increased to a maximum of 5.8-9.8%, whereas O2 decreased to a minimum of 0.7-1%. At equilibrium, the atmosphere had 4.6-7% CO2 and about 1% O2. Bract opening (feathering), toughening, anthocyanin synthesis and ascorbic acid breakdown were suppressed in the packages for 6 days. However, at temperatures above 15 °C visual deterioration and development of severe off-odours occurred. The presence of light in the storage environment had no significant effect on spear quality.
