It has been well-known that 1-MCP (l-methylcyclopropene) is one of the most effective ethylene inhibitor to delay fruits' self-aging. The science behind an I-MCP was originally discovered by Prof. Sisler at North Carolina State, a leading American university for agricultural studies, who studied the natural ripening process of apples in the mid-1990s. Now, 1-MCP is known to be the most effective material to prevent ethylene to trigger ripening process of picked fruits and vegetables. It is a smart and safe way to protect freshness of picked fruits by 1-MCP because 1-MCP itself is not remained in fruits after treatment. That's why there has been an attempt to commercialize this technology and it is currently commercialized by one company. But 1-MCP can not be stored in a conventional way because it can polymerize rapidly in a container as concentrated form. Therefore, how to store 1-MCP gas had been a difficult issue to commercialize 1-MCP to be used to preserve fresh-cut fruits and flowers' freshness longer.
It was Rohm and Haas who firstly developed 1-MCP storing method and they used alpha-cyclodextrine to absorb each 1-MCP molecule separately to prevent polymerization and it was commercialized as name of Smartfresh. The key idea behind this research and development is that if it is difficult to store 1-MCP itself, why we can't generate 1-MCP from stable chemical precursor when we need. We studied the most competitive chemical precursor candidates and optimized 1-MCP generation process. As far as we found out, our technology is conceptually simple and knit to be used and highly economical in terms of cost. A single exposure to 1-MCP can inhibit apple fruit sensitivity to ethylene. 1-MCP delays the onset of the rise in ethylene production and similarly delays the rise in respiration, aroma production, and softening. A single postharvest application could prevent ripening for an extended period, even at ambient temperatures (25℃). I-MCP also can inhibit aroma production in apple fruit and reduce the incidence of the storage disorder, superficial scald.
