Design Of The Best Packages For Three Kinds Of Fresh-cut Radish

This experiment with fresh-cut white radish, fresh-cut red radish and fresh-cut green radish three fresh-cut vegetables best packaging conditions were studied as experimental materials. By feeding of Chitosan Coating Preservation of fresh-cut carrot, respectively of different varieties of fresh-cut carrot packaging materials, coating concentration, coating time and the optimal packing conditions were screened.Specific results are as follows:1. The plastic box and bag compacting respectively of fresh-cut white radish, fresh-cut red radish and fresh-cut green radish packaging, storage period of physiological and biochemical changes in the quality of the experimental. Detection of 4℃in the process of storage water loss rate, color, texture, microbiological and sensory quality changes, combined with each index determination of calibration results of a comprehensive analysis of three kinds of fresh-cut carrot of the most suitable packaging material for the use of compact bag.2. By different concentration of chitosan and different coating time respectively of fresh-cut white radish, fresh-cut red radish and fresh-cut green radish packaging, storage period of physiological and biochemical changes in the quality of the experiment. Detection of 4℃in the process of storage water loss rate, color, texture, microbiological and sensory quality changes, combined with the comprehensive analysis of the results of each index to determine three kinds of fresh-cut carrots the optimum coating concentration is 1%, coating time on storage quality changes did not affect.3. The use of modified atmosphere packaging and support color processing and chitosan coating preservation approach was used in combination with, in storage period detection 4℃ in three kinds of fresh cut carrot dehydration rate, color, texture, microbiological and sensory quality changes and by electronic nose and GC-MS analysis. Results show that, air conditioning, color shield treatment on fresh-cut white radish preservation effect is not obvious, fresh-cut red radish the optimum conditions for the package for coating combined with modified atmosphere packaging, fresh-cut green radish optimal packing conditions for coating and color shield treatment.
