Individual seal-packaging of various fruits and vegetables in high-density polyethylene (HDPE) film delayed their deterioration markedly. The mode of action of this delay in deterioration by seal-packaging was investigated by studying several physiological parameters of citrus fruit and bell peppers. Our findings suggest that HDPE seal-packaging effects were related to the water saturated microatmosphere in the sealed enclosure around the fruit. The hypothesis tested was that this saturated atmosphere alleviates the water stress which exists in harvested fruit as a result of its severance from the water supply of the mother plant. The softening of both lemons and bell peppers was very hihgly correlated with water content and weight loss of non-sealed lemons orbell peppers, while in sealed fruits symptoms of water stress were prevented and firmness was maintained. Some of these HDPE effects could be obtained also by maintaining non-sealed peppers in a water-saturated atmosphere. Activity of polygalacturonase, known to be involved in softening if fruits, was higher in non-sealed fruits. On the other hand, level of cellulase was similar in the 2 treatments. Leakage of amino acids, as an indicator of membrane integrity, was also correlated with the water content of peppers; i.e., leakage was lower in sealed than in non-sealed fruit. |
