The invention concerns a method for preserving vegetable products, in particular green beans enabling to prolong preservation beyond 21 days in heat-sealed trays. Said method uses films with adequate permeability measured with a decision support software to prolong preservation. The optimal permeability of the packaging film depends on parameters, thermal conditioning profile of the distribution channel. Said conditions can be properly fulfilled by using micro-perforated, fog resistant films, with selectivity 1, having a PO2 ranging between 10000 and 4000000 ml/m<2>.24h.atm. |
