Definitions

  • This invention relates to the packaging of bananas.
  • Respiring biological materials consume oxygen (O 2 ) and produce carbon dioxide (CO 2 ) at rates which depend upon temperature and the stage of their development.
  • a respiring material should be stored in a container whose permeability to O 2 and CO 2 is correlated with (i) the atmosphere outside the package, (ii) the rates at which the material consumes O 2 and produces CO 2 , and (iii) the temperature, to produce the desired atmosphere within the container.
  • Bananas are respiring biological materials whose storage and ripening present the most serious problems because
  • a serious disadvantage of the conventional procedure is the need to harvest the bananas a good while before they are fully grown. It would be desirable to harvest the bananas at a later time, when they are larger. However, the later the bananas are picked, the greater the propensity for their climacteric to be triggered by small concentrations of ethylene, and experience has shown that if the bananas are harvested later than the presently established timetables, this results in prematurely ripe bananas when the bananas are shipped in vented bags, and in so-called "green-ripe" bananas when the bananas are shipped in sealed bags. Green-ripe bananas soften, but remain green, and have an unpleasant flavor.
  • Another serious disadvantage of the conventional procedure is that, in order to ripen the green bananas by exposing them to ethylene, it is necessary to open each of the shipping bags if, as in most cases, the bags have been sealed during shipping.
  • Another serious disadvantage of the conventional procedure is that the heat generated by the ripening of the bananas is generated over a relatively short period of time, which heats the bananas to an extent that causes dehydration of the bananas and/or increases the demand on the refrigeration equipment used to keep the bananas cool.
  • the present invention mitigates or overcomes one or more of these disadvantages by packaging green bananas in a sealed container having designed permeabilities to oxygen (O 2 ), carbon dioxide (CO 2 ) and ethylene.
  • this invention provides a method of ripening green bananas which comprises
  • OTR O 2 permeability
  • COTR CO 2 permeability
  • EtTR ethylene transmission rate.
  • OTR, COTR and EtTR values are given in ml/m 2 .atm.24 hrs; in some cases, the equivalent in cc/100 inch 2 .atm.24 hrs is given in parentheses.
  • OTR and COTR values referred to herein can be measured using a permeability cell (supplied by Millipore) in which a mixture of O 2 , CO 2 and helium is applied to the sample, using a pressure of 0.7 kg/cm 2 (10 psi) except where otherwise noted, and the gases passing through the sample were analyzed for O 2 and CO 2 by a gas chromatograph.
  • the cell could be placed in a water bath to control the temperature.
  • the abbreviation P 10 is used to denote the ratio of the oxygen permeability at a first temperature T 1 °C to the oxygen permeability at a second temperature T 2 , where T 2 is (T 1 -10)°C, T 1 being 10°C and T 2 being 0°C unless otherwise noted.
  • R or R ratio is used to denote the ratio of CO 2 permeability to O 2 permeability, both permeabilities being measured at 20°C unless otherwise noted. Pore sizes given in this specification are measured by mercury porosimetry or an equivalent procedure. Parts and percentages are by weight, except for percentages of gases, which are by volume; temperatures are in degrees Centigrade, and molecular weights are weight average molecular weights expressed in Daltons.
  • T o is used to denote the onset of melting
  • T p is used to denote the crystalline melting point
  • ⁇ H is used to denote the heat of fusion.
  • T o , T p and ⁇ H are measured by means of a differential scanning calorimeter (DSC) at a rate of 10°C/minute and on the second heating cycle.
  • DSC differential scanning calorimeter
  • T o and T p are measured in the conventional way well known to those skilled in the art.
  • T p is the temperature at the peak of the DSC curve
  • T o is the temperature at the intersection of the baseline of the DSC peak and the onset line, the onset line being defined as the tangent to the steepest part of the DSC curve below T p .
  • sealing bags containing bananas can be, but generally is not, hermetic sealing.
  • Conventional methods for sealing bags of bananas can conveniently be used in this invention. Such conventional methods include, for example, the use of a cable tie to seal the neck of the bag.
  • a seal made by conventional methods is not a hermetic seal, and has the advantage that it permits equilibration of the pressures inside and outside the bag. If the bag is sealed hermetically, it will generally be desirable to include one or more pinholes in the bag, to achieve such equilibration.
  • the containers used in this invention include an atmosphere control member as defined above, preferably a control member as described in one or both of WO-A- 96/38495 and WO-A-00/04787.
  • the microporous polymeric film preferably comprises a network of interconnected pores having an average pore size of less than 0.24 micron, with at least 70% of the pores having a pore size of less than 0.24 micron.
  • the pores in the microporous film constitute 35 to 80% by volume of the microporous film.
  • Preferred microporous films comprise a polymeric matrix comprising (i) an essentially linear ultrahigh molecular weight polyethylene having an intrinsic viscosity of at least 18 deciliters/g, or (ii) an essentially linear ultrahigh molecular weight polypropylene having an intrinsic viscosity of at least 6 deciliters/g, or (iii) a mixture of (i) and (ii).
  • the microporous film may contain 30 to 90% by weight, based on the weight of the film, of a finely divided particulate substantially insoluble filler which is distributed throughout the film.
  • the polymeric coating on the control member preferably comprises a crystalline polymer having a peak melting temperature Tp of -5 to 40 °C, e.g. 0 to 15°C, or 10 to 20 °C, an onset of melting temperature T o such that (Tp - T o ) is less than 10 °C, and a heat of fusion of at least 5 J/g.
  • the polymer preferably comprises a side chain crystalline polymer moiety comprising, and optionally consisting of, units derived from (i) at least one n-alkyl acrylate or methacrylate (or equivalent monomer, for example an amide) in which the n-alkyl group contains at least 12, preferably at least 14, for example 16-50, preferably 16-22, carbon atoms, for example in amount 35-100%, preferably 50-100%, often 80-100%, and (ii) one or more comonomers selected from acrylic acid, methacrylic acid, and esters of acrylic or methacrylic acid in which the esterifying group contains less than 10 carbon atoms.
  • the polymer can be a block copolymer in which one of blocks is a crystalline polymer as defined and the other block(s) is crystalline or amorphous.
  • Preferred block copolymers comprise polysiloxane polymeric blocks, and (ii) crystalline polymeric blocks having a T p of -5 to 40°C.
  • Such a polymer can be prepared by copolymerizing a mixture of reactants which comprises (i) at least one n-alkyl acrylate or methacrylate in which the n-alkyl group contains at least 12 carbon atoms and (ii) a polysiloxane having a copolymerizable group at one end thereof.
  • polymers which can be used to the coat the microporous film include cis-polybutadiene, poly (4-methylpentene), polydimethyl siloxane, and ethylene-propylene rubber.
  • the gas-permeable membrane preferably has one or more of the following properties
  • control member is as described in US-A-6,013,293.
  • the permeability of the container can be influenced by perforating the container in order to make a plurality of pinholes therein.
  • green bananas are ripened while in a sealed container.
  • the ripening can be carried out in a conventional ripening room containing ethylene, typically but not necessarily at a concentration of 500 to 1000 ppm. It was surprising to discover that, when using suitable containers, it was unnecessary to follow the conventional practice of opening the bags, and that the bananas would ripen satisfactorily in this way.
  • An important advantage of this method of ripening bananas is that the ripening takes place in a more controlled fashion, resulting in lower peak temperatures in the bananas, which in turn results in reduced dehydration of the bananas and, when the ripening is carried out at temperatures below room temperature, reduced demand upon the refrigeration equipment.
  • the temperature at which ripening is carried out and the concentration of ethylene in the atmosphere influence the rate at which ripening takes place. In general, slower ripening results in bananas which remain in a desired range of color stage for a longer period. On the other hand, this must be balanced against delivery dates required by retail outlets and inventory constraints. Generally the ethylene-containing atmosphere will be maintained at the temperature less than 22 °C, preferably less than 20 °C, for example 16-21 °C.
  • the atmosphere within the bags will change substantially during the ripening process, as the bananas consume O 2 and generate CO 2 .
  • the packaging atmosphere for at least part of the period before the bananas reach their climacteric, contains at least 10% preferably at least 12%, particularly 14 to 19%, of O 2 , and less than 10%, preferably less than 4%, of CO 2 , with the total quantity of O 2 and CO 2 being less than 20 %, preferably less than 17 %.
  • the packaging atmosphere preferably contains at least 0.8%, preferably 1.5 to 6%, especially 1.5 to 3%, of O 2 , and less than 15%, preferably less than 7%, of CO 2 , with the total quantity of O 2 and CO 2 being less than 16%, preferably less than 10 %.
  • the invention can in principle be used for any quantity of bananas. However, it is particularly valuable when relatively large quantities are involved. Thus it is generally preferred that the sealed container contains at least 4 kg, preferably at least 15 kg, especially 16 to 22 kg of bananas.
  • the invention is illustrated in the following Examples, a number of which are comparative Examples, designated by the letter C before the number of the example.

  • Each bag was packed with about 18.1 kg (40 Ib) of green bananas. The bananas had been harvested at week 13, and maintained at 13-14°C for about 11 days after harvest before being packed. Except in Example C14, excess air was extracted from the bags using a vacuum pump, and then securely tied. In Example C14, the bags were left open. The sealed bags were cooled to about 13 °C and shipped to Gulfport, Mississippi, and then to San Francisco, California, maintaining the temperature at about 13°C.

About 24 hours after the generation of ethylene had begun, the room was vented.
  • the temperature of the bananas was monitored for about 15 days, and reached a peak at about 60 hours after the generation of ethylene had begun. At that time, the concentration of O 2 and CO 2 was measured. The results are shown in Table 3 below.
