Abstract

Broccoli is an important vegetable due to its economic and nutritional value. It shows quick senescence, characterized by yellowing, loss of turgecency, development of off-odors, increase in enzymatic activity and loss of nutritional value. Among the techniques that can extend its shelf life, we have cooling and modified atmosphere packaging. There are some factors that interfere in the efficiency of MAP, influencing the speed and the intensity in the atmosphere modification. This work aimed to evaluate the influence of broccoli packed weight (bi-oriented polypropylene film) on its color, odor and enzymatic activity during its post harvest period when stored at 1ºC. Afterwards, a strong influence was verified when packing was used, for in all packaged treatments lower enzymatic activity was observed. It was also observed that, among package treatments, those with more filling weight showed the worst performance about odor, chlorophyll rage and enzymatic activity
