저장 중 무화과(Ficus carica L) 선도유지를 위한 고농도 이산화탄소 처리된 포장 시스템 적용 연구

Abstract

This experiment was conducted to establish the optimum conditions for high gas treatment in combination with a proper gas-permeable packaging film to maintain the quality of fig fruit (Ficus carica L). Among the fig fruits with different high treatments, the quality change was most effectively controlled during storage in the 70%--treated fig fruit. Harvested fig fruit was packaged using microperforated oriented polypropylene (MP) film to maintain the optimum gas concentrations in the headspace of packaging for the modified-atmosphere system. MP film had an oxygen transmission rate of about /day/atm at . The weight loss, firmness, soluble-solid content (SSC), acidity (pH), skin color (Hunter L, a, b), and decay ratio of the fig fruits were monitored during storage at 5 and . The results of this study showed that the OPP film, OPP film + 70% , and MP film+70% were highly effective in reducing the loss rate, firmness and decay occurrence rate of fig fruits that were packaged with them during storage. In the case of using treatments with packages of OPP film and OPP film+70% , however, adverse effects like package bursting or physiological injury of the fig may occur due to the gas pressure or long exposure to . Therefore, the results indicated that MP film containing 70% can be used as an effective treatment to extend the freshness of fig fruits for storage at a proper low temperature.
