Postharvest fruit preservation practices often focus on controlling ethylene production. Inhibitors such as aminoxyacetic acid (AOA), salicylic acid (SA), 2,5-norborndioic acid (2,5-NBD), silver thiosulfate (STS), aminoxyethylene glycine (AVG) and 1 -Methylcyclopropene (1-MCP), both can effectively control ethylene production.
Among them, the characteristics of non-toxicity, low concentration, high efficiency and ease of use make 1-MCP a widely used and effective tool for post-harvest preservation of fruits, vegetables and cut flowers.
As a cyclopropene derivative, the molecular structure of 1-MCP is similar to the natural plant hormone ethylene. It can block the binding of ethylene receptors on the epidermis of fruits or flowers to ethylene, inhibit the ethylene signaling pathway, and break the cycle of ethylene promoting ripening. Therefore, it can effectively delay fruit ripening and improve the shelf life of fresh agricultural products. 1-MCP has become a widely used preservation product to maintain the freshness of fruits, vegetables and cut flowers and extend their shelf life, making transportation easier.
