CHLOROPHYLL DEGRADATION DURING CONTROLLED‐ATMOSPHERE STORAGE OF ASPARAGUS

摘要

SUMMARYChanges during CA (controlled‐atmosphere) storage of excised shoots of asparagus (Asparagus officinalis L) were studied. Storage in 5 CO2, at 35°F and 95 relative humidity resulted in increased pH, decreased total acidity and total solids, and an increase in soluble solids. There was also more retention of chlorophylls in the CA‐stored asparagus. These effects became more pronounced as the concentration of CO2in the atmosphere was increased. The degradation products of chlorophylls in the CA‐stored samples were exclusively the pheophytins. Correlations between changes in pH and the degradation of chlorophylls wer
