| The storability of chicon was compared by packing it with PE box, wrap, LDPE (low density polyethylene) film that was 25 and 50um thickness, respectively and storing at 1 and $10^{circ}C$ under light and dark conditions. The visual quality depending on dehydration was deteriorated at more than $2%$ weight loss during storage. In packing treatments, chicon packed with PE box lost fresh weight to $3%;at;10^{circ}C;and;2%;at;1^{circ}C$, while non- penetrated film treatment, wrap, 25 and 50um thickness LDPE film, showed less than $1%$ weight loss. The carbon dioxide concentration in package was $3~4%;in;50{mu}m$ LDPE film at $1^{circ}C; and;25um$ LDPE film at $10^{circ}C$. The ethylene concentration in 50um LDPE film at $1^{circ}C;and;25{mu}m$ LDPE film at $10^{circ}C$ was approximately 0.3 ppm and 0.5 ppm, respectively. Chiton stored in dark condition didn't turn to green, but it fumed green only in 3 days at $10^{circ}C$ and in 6 days at $1^{circ}C$ under light condition. The greening of chicon was less, the packing materials was thicker. The chlorophyll content represented the degree of greening showed less at $1^{circ}C$ then at $10^{circ}C$. The coefficient of correlation(r) between chlorophyll content and carbon dioxide concentration in package was 0.926 at $1^{circ}C$ and 0.997 at $10^{circ}C$. The visual quality except greening of packed chicon was maintained at $1^{circ}C$ better than $10^{circ}C$, and it was shown highest grade packed with $50{mu}m$ LDPE film at $1^{circ}C$ and packed with 25um LDPE film at $10^{circ}C$. The vitamin C content in packed chicon was kept higher at $1^{circ}C$ on storage temperatures, and 25um and 50um LDPE film on packing materials. According to these results, it can be proper condition for storage and marketing of chicon that 50um LDPE film at $1^{circ}C$ and 25um LDPE film at $10^{circ}C$. And dark condition is necessary to store chicon because it should turn green under tiny light condition. |
