Description
The present invention relates to a kind of method of packaged food, wherein the food that will pack is carried out sterilization or pasteurized process, even the cooking is handled.
Heat-treat in pressure container with steam, to the food packet sterilization that carries out disinfection, this simple food packet, i.e. so-called " distillable package ", be intrinsic unalterable rigid pack so far always, as have the jar or the glass container of rigid cap.These packages or fill with hot food are perhaps handled with steam simultaneously at osed top.Vapour treatment relates at 15p.s.i(1.05kgf/cm
2) the interior use of scope superatmospheric pressure, and when applying the steam pressure of handling and/or cooling off, package will stand thermal shock.Thermal shock is absorbed by the end of jar or the flexural deformation of bottle cap, perhaps in this case, package is carried out vacuum packaging, offsets thermal shock by the effect that vacuum-packing method produces.
Complicated distillable package is another kind of situation, and it needs additional hyperpressure during vapour treatment, break to prevent package, and this hyperpressure is provided by pressurized air.When exerting pressure and/or during cooling packing spare, also existing the problem that package frequently suffers thermal shock.
Except that above-mentioned, simply seal baked goods, for example the package of cake and bread can carry out pasteurization, but needs unencapsulated passage, and when carrying out pasteurization so that convenient package is pressurized, authorized pressure and steam discharge.After the cooling, content for fear of package is polluted again, must seal these passages, therefore, be perfectly clear, this exists air and enters package again, pollute sizable danger of package loaded article, want to make the steam pressure in the package to reach enough height, temperature also is very difficult near boiling point and do not make sealing place or package fracture.
For containing wetly baked goods, resemble the food that those have high moisture content, for example bread and muffin, for its provide the method for package must be can avoid to heat sensitive, have that the germ and the special mould of growth forms occurs as the plant.
An object of the present invention is to provide a kind of package, it can alleviate or address the above problem, and provides the package of retortable or simple seal, can heat-treat the content in the package.
According to the present invention, a kind of method of packaged food is provided, it comprises the steps, food is put into container, container is made by the fibrous material of mold pressing, and lining is with the thermoplastic film, perhaps make by heat-resisting plastic material, with container edge with can stop bacterium to see through, but can allow the cover film material heat seal of water and gas permeation, heat seal carries out under following state, and thermoplastic film's material is extended along cladded material fully, so that sir-tight sealing is provided, the heat treatment package makes content sterilization or pasteurization, cooling and dry packing spare, with cladded material and isolated film heat seal, isolated film can stop moisture to see through or allow in check moisture to see through.Selectively, the package of finishing is carried out radiation sterilization.Radiation sterilization especially need be to the package head room disinfection between cover film and isolated film, and especially very moist the and high food of activated water content more needs to do like this for those., in many baked goods, the activity (humidity relative equilibrium percentum) of final water is very low, is enough to prevent the space breeding growth of mould between cover film and isolated film.
Heat treatment can be adopted the form of using steam to handle in autoclave or similar containers, so that reach the purpose of the interior contents in the package with the steam disinfection sterilization.In addition, can preferentially select the piece installing of dielectric heating heat packs, in package, produce steam, content is carried out pasteurization or sterilization.
The container that is used for method of the present invention is preferably made by the porous fiber material, for example: the article shaped of the fibre stuff that the conventional approach of use paper conversion technology mold pressing processing fiber material is made, paper, cardboard or board fiber board.Also can select, adopt the composite material that provides in conjunction with wood chip or binding fiber material to make container, composite material has the ability to stand the heat treatment under disinfection or the pasteurizing conditions.Container also can or have the plastics of fibrous structure to make by foamed plastic, this plastics can comprise filler, and can stand the heat-treat condition of disinfection or pasteurization, perhaps with the plastics that can stand disinfection or pasteurization heat-treat condition, make container such as nylon (nylon), polyethylene terephthalate (polyethylene terephthalate) or polymethylpentene (polymethylpentene) through injection moulding or mold pressing, if package needs to carry, the latter is the special material that uses.
With thermoplastic material, this thermoplastic material can fusion under the heating and the condition of exerting pressure, and combines with cladded material, and can stand heat-treat condition with containers lining of porous fiber material manufacture for those.The material that can be fit to liner comprises: nylon (nylon), polyester (polyesters), polypropylene (polypropylene) and comprise other polyolefin (polyolefins) and other polymeric material.Preferred gasket material is an ionomer.In this ionomer, the carboxyl of ionization group produces the ion cross linkage in molecular structure, and these ion cross linkages are reversibly destroyed in melt temperature.Hereinafter for convenience's sake, this poly-mer is called " ionomer ", and best ionomer is sold with registered trade mark (RTM) " SURLYN ".
Cladded material is a kind ofly can make gas and moisture vapor transmission, but can prevent the material that germ passes through.Preferred this material is so-called " medico paper ", and it is sold with trade mark " STERI-SHEET ", and fiber wherein is set, so that stop bacterium and other germs to pass through.Can replace medico paper with microporous polypropylene film, as this film that uses registered trade mark (RTM) " VALMIC " to sell.
After food is packaged, put into container.With moulding bracing frame and temperature booster heat seal package.In this state, make the fusion of thermoplastic plastic liner, and flow along cladded material, so that sir-tight sealing is provided, and can not have the situation of moisture absorption to take place at the whole edge of container.Being suitable for thermosealed temperature, is 170 ℃ to ionomer and polypropylene-made liner, is 220～230 ℃ to nylon and polyester liner.
Then, package is heat-treated.Among the embodiment in the methods of the invention, package is put into autoclave or pressure container, carry out the moise-heat sterilization sterilization in conjunction with reasonable time, temperature.According to the needs of content in the package, the perhaps germ state of content, according to the food processing rule, this sterilization treatment can be from condition F
1, i.e. steam pressure 15p.s.i(1.05kgf/cm
2), 15 minutes time, to condition F
4, i.e. steam pressure 15p.s.i(1.05kgf/cm
2), 45 minutes time, the temperature under various occasions is 121.5 ℃.During the package sterilization, distortion can appear, and cladded material forms the dome that protrudes on package.
In another embodiment of the inventive method,, make and produce steam in the package in micro-wave oven or heat packs piece installing in microwave or radio frequency tunnel with the dielectric energy, rise to 65～100 ℃ of the values of hope to cause ambient-air temperature in the package.The grade of cladded material, thickness, material, physical property with and distinguishingly allow the penetrablility of gas and vapour transmission, make and finish in heating period, will preserve water capacity appropriate and hope in the food.In addition, the steam that forms during heating process produces pressure in package, and force value can cause cladded material flexural deformation, forms the dome that protrudes, and can suitably select temperature.Sealing intensity between the polymeric liner bed course of cladded material and plate or plate, and the steam that the elasticity of plate and wet covering paper allows to be produced by inside in package forms superatmospheric pressure, and do not make package fracture or destruction.For example, in 700 watts of micro-wave ovens, a small pieces of wet bread just can produce " superatmospheric pressure " in 30～40 seconds.In the short time of temperature more than 70 ℃, be enough to kill mould and their spore.Water capacity is carried out certain adjustment be necessary, when passing cladded material, moisture is reduced with convenient steam.
After disinfection or pasteurization heat treatment, package is cooled, the steam that occurs in package can flow out by cladded material, the elasticity of container and its laying and elasticity make pressure eliminate naturally simultaneously, and no longer outwardly-bent distortion, the distortion of Fa Shenging is during heating treatment corrected, and returns to the state of self originally.Then, package is carried out natural seasoning, perhaps carry out force drying, be preferably under the aseptic condition and carry out with air.Cladded material prevents the germ intrusion.And under drying regime, package can be complex polyester/polyvinylidene chloride (polyvinglidene chloride)/polypropylene film with suitable moistureproof isolated film heat seal, isolated film.More again, provide sir-tight sealing, so that prevent that it is very important sucking moisture between isolated film and cladded material at the edge of package.
Undoubtedly, mycelia can grow by cellulosic lamination coating, and can pass cladded material, and in order to prevent the growth of mould, last package will carry out radio sterilization.Preferably adopt the ultraviolet light of suitable wavelength, so that the spore of kill microorganisms and mould, they can occur in the cladded material and the space between the isolated film at package top.For the high-moisture content is arranged, exist the fungus growth problem, thereby package is carried out above-mentioned radio sterilization is particular importance.
At ambient temperature, through the package of pasteurization, its result can prolong storage period, and can obtain stable microbiological property.Its storage life depends on the laying of container and the permeability to air of isolated film.
