초록 ▼

A method for determining and controlling the proper modified or unmodified atmosphere packaging for cut or uncut respiring perishables such as cauliflower, lettuce and broccoli includes the steps of determining the respiration rate of the respiring perishable, preparing a plurality of packages containing the respiring perishable with each package having a different permeant factor, determining a value called atmosphere quotient for each of the packages according to this formula: atmosphere quotient equals permeant factor divided by respiration rate; subjecting each of the packages to known conditions of temperature and pressure over a known period of time and correlating the subjective and objective indicia of quality, appearance and marketability of the respiring perishable from each package to the atmosphere quotient values determined according to the foregoing formula, and then varying one or more of the values of the components that affect permeant factor to achieve and maintain the optimum value or range of values for atmosphere quotient.

A method for optimizing the shelf life of at least one respiring perishable in a package made of packaging material that transmits oxygen and carbon dioxide comprising the following steps: (1) determining the respiration rate (R) of said perishable; (2) selecting a packaging material for said respiring perishable that has known or ascertainable transmissibility to oxygen and carbon dioxide; (3) preparing a first plurality of packages, each package containing said perishable in said packaging material, and each of said first plurality of packages having a different permeant factor (G) and different atmosphere quotient value (AQ) from the other packages in said first plurality, where G is equal to: the are (A) of said packaging material required to enclose a given weight of said perishable in a gaseous atmosphere that includes oxygen, multiplied by the permeability (P) of said packaging material to carbon dioxide or oxygen, and divided by the weight (W) of said perishable to be enclosed in said package; and wherein AQ is equal to G divided by R and said different permeant factors result from varying at least one of A, P or W in each package of said first plurality; (4) subjecting each of said packages in said first plurality containing said perishable to the same given, known temperature and pressure over a known period of time; observing the quality, appearance and marketability of said respiring perishable in each of said packages after the gaseous atmosphere in each of said packages reaches equilibrium; and, based on these observations, determining which of said packages has optimum shelf life; (5) repeating, as necessary, steps (3) and (4) with at least one additional plurality of packages, each of said additional packages having permeant factors different from the packages in said first plurality and different from the other packages in said additional plurality until an AQ value representing optimum shelf life for said perishable has been determined; (6) from the atmosphere quotient values determined in steps (3), (4) and (5), deriving the equivalent permeant factors G for those packages which have optimum shelf life as determined in step (4), in accordance with the formula AQ equals G divided by R; and (7) using said equivalent permeant factors G, preparing an optimum package containing said perishable from said packaging material by varying one or more of the variables A, P and/or W while maintaining said equivalent permeant factor G to achieve and maintain the optimum atmosphere shelf life for said perishable in said optimum package.
