Modilicd atmosphere packaging (MAP) emerged in the 1970s as a IlCW technology that may extend life of perishable agricultural produce. However. if proper precautions arc not taken this technology may also risk the microbiological sakty of the packaged food. Perforated IIlms enable MAP to maintain H20-saturation with only a slight change in 02 and CO2, This results in reduction of water loss and al iL'viation of water stress without the possihle deleterious effects of anaerohiosis or CO2 damage. New trends of rescarch are m the dewlopment of interactive or . smart" films. These new films may be expected somehow to sense the changing internal packaging t'nvironment and admit oxygen from the outer atmosphere or allow excess CO2 to escape. Modified humidity packaging, comhined with incorporation of fungicides into films, heat treatment. etc" are new. promising lines of research. Mathematical modelling for gas exchange in MAP is based on a combination of Fick's Law and th" Michael is Menten e4uation. This model enables production of the optimal parameters of a package. Surface coatings have gained some cOl1lmcrcialuses due to the availahility of edihle and natural origin coatings.
