A Study on Supercooled Storage of Leaf Lettuces Produced in Plant Factory

Abstract Much emphasis is now being given to research and development of plant factories with fully closed and artificially controlled environment, aimed at supplying various vegetables safely and constantly. Plant factories daily produce large amount of high quality vegetables under artificially controlled environments. However, the demands from the customers are not constant, and the unsold vegetables should be disposed due to their short shelf-life and the risk of foodborne illness after the short period of storages. So, one of the important issues to be considered is to establish suitable storage systems for providing an acceptable length of shelf-life and for minimizing the risk to foodborne illnesses. This section deals with the application of the supercooled technique to the storage systems for extending the shelf-life of the high quality leaf lettuces produced by the plant factories.
