Abstract
Abstract A method for preserving banana pulp, wherein the pulp of said fruit is firstly pressed in an atmosphere of an inert gas, preferably helium, and then deep-frozen and packaged in tightly closed, gas-impervious containers. Such containers are then to be kept at a low temperature, in the way as usually followed for all deep-frozen foods. A few pieces of biscuit may be enclosed within the containers, along with the banana pulp, in order to maintain the good appearance of same pulp.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
85 words
A METHOD FOR PRESERVING FRUIT PULPS HAVING A HIGH IRON SALT CONTENT, COMPRISING THE STEPS OF PRESSING A FRUIT PULP IN A MOLD TO FORM A CAKE, PACKAGING THE CAKE IN A CONTAINER MADE OF A GAS-IMPERVIOUS MATERIAL, DEEP-FREEZING THE CONTAINER AT A TEMPERATURE IN THE RANGE FROM ABOUT -40*C. TO ABOUT -50*C. AND FINALLY SEALING SAID CONTAINER, ALL OPERATIONS, FROM PULP PRESSING TO SEALING OF THE CONTAINER, BEING PERFORMED IN AN ATMOSPHERE SUBSTANTIALLY FREE FROM OXYGEN SO THAT THE IRON SALTS ARE NOT OXIDIZED.
