摘要
远洋蔬果复合气调保鲜包装系统(MAP)不仅工作情况复杂,而且海洋上O2在大气中约占25%,一般陆地空气中O2只占21%,同时海洋大气压比陆地又高。为了优化远洋蔬果复合气调包装系统设计,缩短试验研究过程,本文根据Fick定律和Henry定律以及蔬果复合气调包装后气体质量平衡原理建立数学模型,从而确保远洋蔬果复合气调保鲜包装的科学性,达到延长远洋蔬果保鲜期的目的。
The compound MAP （modified atmosphere packing） system for ocean shipping of vegetables/fruits works under complex fresh-keeping conditions. Moreover, the oxygen concentration in oceanic atmosphere is about 25% but it is only about 21% in the atmosphere above land. And the atmosphere pressure above ocean is higher than above land. To optimize the design of the foregoing MAP system and shorten the relevant testing/investigating process, a mathematical model was developed according to the Fick＇s law, Hemy＇s law and the principle of mass equilibrium during gas exchange after MAP. Thus, the reliabihty of keeping freshness of vegetables/fruits after ocean shipping can be ensured via compound MAP with the period of efficient storage prolonged.
