Abstract

The shelf life of banana is very much dependent on the processing, storage conditions and packaging design. Ordinary food packaging method traps air with the food product. Oxygen and moisture in the air cause the banana to degrade over time, lose flavor and nutrition as well as shorten the shelf life. Vacuum packaging is an effective solution that can be used to remove air in food package thus inhibit the growth of bacteria, mould, and yeast that contribute to food spoilage. Besides that, vacuum packaging can help to secure, seal, thus increasing the shelf life and keeping banana fresh longer. Therefore, this project is directed towards determining the effect of utilizing vacuum packaging and storing in various condition towards extending the shelf life of banana. Peeled and unpeeled; and vacuum packed (VP) and non-vacuum packed (NVP) banana were kept at different storage conditions which include room temperature (25°C ± 3°C), cold temperature (9°C±2°C) and freezer temperature (-20°C ±2°C) for one month. The shelf life of banana was investigated in term of physical properties such as texture, moisture content and color changes and also in term of antimicrobial properties which was total plate count (TPC) of the colony. Based on the physical analysis, vacuum packaging and -20°C storage temperature was found to significantly delayed the ripening process in terms of fruit firmness, color changes and moisture content. This was due to the fact that the bananas were vacuum packed with good oxygen and moisture barrier properties of low density polyethylene (LOPE) bag hence reduction in oxygen content as well as low storage temperature had retarded the chemical reaction in the bananas. Antimicrobial analysis also revealed that, VP banana exhibited less colony forming unit (CFU/ml) than NVP banana.
