Abstract
Peas are one of the most important vegetable crops in Egypt. The shelf life of fresh peas is shorter than processed ones, so the use of modified atmosphere packaging (MAP) can play an important role in extending their shelf-life. Studies were carried out on modified atmosphere packaging of peas for variety Master B. The peas were packaged in lowdensity polyethylene (LDPE) and polyproplyene (PP) of 50 and 55 mµ thickness respectively. These packages were stored at 0, 5, 15C° and room temperature and evaluated for quality at different storage periods. The treatments comprised modified atmosphere packaging (MAP) 3% O2 + 7% CO2 + 90% N2 headspace and normal air (control). The shelf life of peas packaged in (LDPE) and (PP) under MAP was 38, 20, 9 & 5 days and 33, 17, 8 & 5 when stored at 0, 5, 15C° and room temperature, respectively. The quality indices like total soluble solids, moisture conten, pH value, microbiological analysis, weight loss and decay were determined . The shelf life of peas was 20 and 17 days when packaged in (LDPE) and (PP) with (MAP) at 5C°, but it was 17, 15 days with normal air (control) at the same temperature. Statistical analysis showed significant effect of temperature and storage period on total soluble solids, moisture content, pH value, microbiological analysis, weight loss and decay of peas.
