摘要：To mi.i.i.e losses between harvest and retai. di.play, a system i. needed to track temperature and RH exposure of fresh produce and predi.t i.s quali.y at each step of the di.tri.uti.n chai.. Wi.h accurate models, such system could （1） i.enti.y problemati. si.uati.ns before losses occur; （2） become a management tool for deci.i.n makers; and （3） help quanti.y the real i.pact of i.di.i.ual i.appropri.te condi.i.ns. A project was i.i.i.ted to develop models requi.ed for such a deci.i.n system. Because the data requi.ed to develop models were not avai.able for most frui. and vegetables, a seri.s of storage tri.ls was planned for measuri.g changes i. physi.logi.al and mi.robi.l quali.y, and development of physi.logi.al di.orders and/or di.eases, as a functi.n of ti.e, temperature and RH. To meet thi. objecti.e, controlled envi.onment mi.i.chambers were desi.ned, bui.t and i.strumented for measuri.g the effect of traceable envi.onmental condi.i.ns encountered duri.g storage and transportati.n of fresh horti.ultural produce of si.i.ar si.e and shape as tomato. Detai.ed desi.n and performance evaluati.n of these mi.i.chambers are presented.
