美国加利福尼亚大学以其对易腐品处理和运输的研究成果而闻名于世。据该大学的运输调配专家M·约瑟夫·阿伦斯博士介绍:“……每一种商品均有其保持自身最佳质量的特定环境。这种环境由特定的温度、湿度、呼吸气体(二氧化碳和氧气)以及乙烯之类的挥发性气体等元素所构成。不同种类的商品对环境中各个组成元素均有不同的反应。通过调整这些元素的比例关系能延长农产品的货架寿命,减 The University of California is famous for its research on the handling and transport of perishables. According to Dr. M. Joseph Ahrens, a transportation expert at the University, "... every single commodity has its own particular environment of maintaining its own best quality, defined by specific temperature, humidity, breathing gas (carbon dioxide And oxygen), and volatile gases such as ethylene, etc. Different types of commodities have different reactions to the various components of the environment, and the proportion of these elements can be adjusted to extend the shelf life of agricultural products, minus
