PROBLEM TO BE SOLVED: To design a package for vegetables and fruits with accuracy in a short time.SOLUTION: This method for designing the package for vegetables and fruits includes steps for specifying an enzyme related to the quality of vegetables and fruits (S101), preserving vegetables and fruits packaged in a package having holes for oxygen to permeate, and acquiring a relationship between the design specification of holes and the variation of the enzyme before and after the preservation of vegetables and fruits (S106), and determining design specifications for making the variation of the enzyme when preserving the vegetables and fruits for a predetermined period using the package, to a predetermined threshold value or less based on the acquired relationship (S108).COPYRIGHT: (C)2012,JPO&INPIT【課題】短時間で、かつ、精度よく、青果物用包装体を設計する。【解決手段】本発明に係る青果物用包装体の設計方法は、青果物の品質に関係する酵素を特定するステップ(S101)と、酸素を透過する孔を有する包装体で包装された青果物を保存し、孔の設計仕様と、青果物の保存前後における前記酵素の変化量との関係を把握するステップ(S106)と、把握した関係に基づき、包装体を用いて所定期間青果物を保存したときの酵素の変化量を所定の閾値以下にする設計仕様を決定するステップ(S108)とを含む。【選択図】図1
