Definitions

  • the present invention relates to a method for packaging climacteric fruit and a package obtained with said method.
  • climacteric fruit is used to indicate a fruit the ripening of which comprises a step characterized by the appearance of a breathing peak (climacteric peak) and by an increase in the production of ethylene (C 2 H 4 ).
  • climacteric fruit are bananas, apples, pears, peaches, plums, nectarines, tomatoes.
  • bananas arrive on distribution markets a long time after they have been picked. Bananas are picked from the tree while still unripe and are transported by transport means such as ships (banana-boats), cars or containers, toward the countries of the distribution markets. In the transport means, the unripe bananas are kept in a refrigerator and when they are unloaded they are transferred to other refrigeration cells from which they are removed in relation to market demand, when they have to be made to ripen. Their ripening is caused by creating, in ripening cells, suitable conditions of temperature, degree of relative humidity, and, especially, providing them with a suitable quantity of ethylene to trigger their ripening process.
  • air is added (about 20% of oxygen (O 2 ) and 80% of nitrogen (N 2 )) with the addition of about 0.1% of ethylene; relative humidity is adjusted to 90-95% and temperature to 20-22°C.
  • O 2 oxygen
  • N 2 nitrogen
  • the bananas are kept in the ripening cells for about forty-eight hours. Periodically, the air is changed to avoid an accumulation of carbon dioxide (CO 2 ) that would produce fermentation in the bananas.
  • CO 2 carbon dioxide
  • the bananas When the bananas have reached the desired degree of ripening, they are distributed in the points of sale to the public. Once put on sale, the bananas must be consumed within the space of a week, at most.
  • this process is also fairly rigid in that, once the ripening process has started in the cells, the bananas must be sold and consumed in a comparatively short time interval.
  • the object of the present invention is a method for packaging climacteric fruit and a package containing the same fruit that allow their distribution cycle to be made simpler, flexible and economical.
  • the method of packaging and the package according to the invention it is possible to keep unripe fruit at room temperature for periods of about two, three months. After which, in order to trigger the ripening process, it is sufficient to open the bag. About a day and a half, two days, after the opening of the bag, the fruit reaches complete ripening and exhibits organoleptic qualities comparable to those of fruit ripened in the ripening cells.
  • the ripening of the fruit according to the present invention can be activated at any time, by opening the bag that contains them, about two, three days after packaging.
  • the method of packaging and the package according to the invention exhibits several advantages. They simplify the distribution cycle of the fruit, they reduce its costs and they make it more flexible. In fact, they allow the usual ripening cells as well as the refrigeration cells to be eliminated, if the fruit is packaged immediately after being unloaded from the transport means. Moreover, they allow the consumer to keep the fruit without particular precautions up to the end of the storage period (about two, three months) and, especially, they allow the fruit to be consumed at the time that is felt most appropriate.
  • a package 1 for a banana 2 comprising a bag 3 formed by a film of suitable material having a preselected permeability to gases and to aqueous vapour.
  • the bag 3 is closed hermetically along edges 4.
  • the material of the bag 3 is selected from the group comprising: low-density polyethylene (LDPE), polyethylene (PE), high-density polyethylene (HDPE), polypropylene (PP), oriented polypropylene (OPP), polyvinylchloride (PVC), oriented polystyrene (OPS), polyethylene terephthlate (PET), polyvinyl acetate (EVA), polyvinyl alcohol (EVOH).
  • LDPE low-density polyethylene
  • PE polyethylene
  • HDPE high-density polyethylene
  • PP polypropylene
  • OPP polypropylene
  • PVC polypropylene
  • PVC polyvinylchloride
  • OPS polystyrene
  • PET polyethylene terephthlate
  • ETA polyvinyl acetate
  • EVOH polyvinyl alcohol
  • the film of the bag 3 has a thickness ranging from 20 to 50 microns, preferably 35 microns.
  • the bag 3 is filled with a modified atmosphere comprising oxygen in a quantity ranging from 2% to 20% by volume, preferably from 2% to 6% by volume, carbon dioxide in a quantity ranging from 0% to 20% by volume, preferably from 6% to 13% by volume, ethylene in a quantity ranging from 0% to 3% by volume, preferably from 0.1% to 1.5% by volume, the remainder being nitrogen.
  • a modified atmosphere comprising oxygen in a quantity ranging from 2% to 20% by volume, preferably from 2% to 6% by volume, carbon dioxide in a quantity ranging from 0% to 20% by volume, preferably from 6% to 13% by volume, ethylene in a quantity ranging from 0% to 3% by volume, preferably from 0.1% to 1.5% by volume, the remainder being nitrogen.
  • the bag 3 is formed by a film of LDPE 35 microns thick having permeability to oxygen equal to 6,800 cm 3 /m 2 24 h atm, to carbon dioxide equal to 25,000 cm 3 /m 2 24 h atm, to ethylene equal to 22,000 cm 3 /m 2 24 h atm, where permeability is determined with the method of ASTM-D 1434. Permeability to aqueous vapour is equal to 10 g/m 2 24 h, determined according to the method ASTM 389 83.
  • the bag contains a modified atmosphere comprising 2% by volume of oxygen, 8% by volume of carbon dioxide, 0.1% of ethylene and 89.9% of nitrogen.
  • the package 1 is prepared when the bananas are still unripe (green), after being unloaded from the banana-boats or after a stay in refrigeration cells.
  • the procedure is to insert in the bag 3 one still unripe banana 2, or two or more bananas.
  • the bag 3 is filled with the modified atmosphere having the composition indicated above and it is closed hermetically by sealing under heat. Filling the bag 3 with the modified atmosphere and sealing under heat are performed with traditional packaging machines, provided with cylinders for the supply of the required gases.
  • the package 1 can be kept at room temperature for about two, three months.
  • the composition of the modified atmosphere remains substantially constant. During this period of time, starting with about the second, third day after packaging, the banana can be made to ripen at any time by opening the bag 3 and leaving it under environmental conditions for a day and a half, two days.
