Abstract:
Effects of preparation and modified atmosphere on storage quality and shelf-life of shredded cabbage were studied. The study was divided into three experiments. In the first experiment, the effect of sodium hypochlorite at three concentrations; 0 50 100 and 200 ppm and washing time; 5 and 10 minutes on the growth of microorganisms were investigated. It was found that washing in sodium hypochlorite 200 ppm for 5 minutes gave the best result in decrease the number of microorgainism. The second experiment was to study the effect ofvarious types (LLDPE and PVC) and thickness of plastic films, (15 and 25 pm) on shelf-life of shredded cabbage kept at The shredded cabbage wrapped with PVC showed the longer shelf- life than the shredded cabbage wrapped with LLDPE. However the highest water loss was found in shredded cabbage wrapped with PVC plastic films. Shredded cabbage wrapped with PVC plastic film had shelf-life of 4 days while both wrapped with 15 and 25 pm LLDPE had shelf-life of 3 days. In the third experiment, the effects of packaging type, PE plastic bag with hole and no hole on storage quality of shredded cabbage during being stored at 5 and 10 C were studied ilr results showed that shredded cabbage storage at 5 'C with no hole could maintain a better quality than the shredded cabbage storage at 10 'cin PE plastic bag with hole and no hole and its the shelf-life was extended 8 days.
