ABSTRACT:
The humidity-dependent antibacterial powdery composition comprises a volatile oily antibacterial substance contained in a high ratio and a water-soluble film forming agent and the behavior of release of the antibacterial substance is changed depending on humidity. The process for producing the same is characterized in that a water-soluble film forming agent optionally together with a powder vehicle is dissolved and/or dispersed in water, subsequently a volatile oily antibacterial substance optionally together with an emulsifying agent is added to the solution and emulsified, and thereafter the obtained emulsion is spray dried into powder. The humidity-dependent antibacterial food storing article is characterized by carrying the humidity-dependent antibacterial powdery composition. The method of storing food is characterized in that the volatile oily antibacterial substance is released from the humidity-dependent antibacterial food storing article toward food lying in an atmosphere of 70% or higher humidity.
