ABSTRACT:
A process for preserving fresh fruit or vegetable products comprises the steps of; heating the fruit or vegetable product rapidly and uniformly to a temperature sufficient to destroy the natural enzymes which are present in the product without cooking the product, and immediately thereafter, cooling said product rapidly to a cold condition to remove the enzyme destroying heat before any significant cooking of the product can occur and to cool the product to a temperature which will inhibit deterioration of the freshness thereof. Shortly thereafter, while the product remains in said cold condition, it is placed in a sealed gas-type package. Shortly thereafter the package product is irradiated to an extent sufficient to sterilize the product and prevent the formation of degenerative gas in the product, without damaging the product to thereby provide an enzyme-free, sterile and hermatically packaged fruit or vegetable product which has its fresh flavor and texture characteristics substantially unaltered and which can be stored without deterioration of freshness, flavor or texture for a long time.
