Effect of low temperature and controlled atmosphere storage on the membrane lipid composition of broccoli flower buds.

Heads of the broccoli cultivars Stolto, Commander and Green Valiant were stored for 6 or 9 weeks at 1 deg C in atmospheres containing N2 and 0% CO2+20% O2 (air) or 8.5% CO2+2.5% O2 (CA). During storage in air the phospholipid content decreased and the free sterol:phospholipid ratio increased. These changes were delayed under CA. The slight increase in the degree of unsaturation of the phospholipid fatty acids observed during storage in air was also delayed under CA. Storage had little influence on sterol content. The results showed close correlations between phospholipid degradation, increase in sterol:phospholipid ratio and postharvest senescence of broccoli flower buds. It is suggested that development of treatments which would stabilize the cell membranes would improve the postharvest conservation of broccoli.
