Definitions
- STERILISING MEDIUM METHOD FOR PREPARING THE STERILISING MEDIUM
- the present invention relates to a sterilising medium for sterilisation of packaging material for food packaging containing an aqueous solution of hydrogen peroxide and a spreading agent additive composition.
- the invention also relates to a method of preparing the sterilising medium, the method of sterilising a laminated packaging material, or a container thereof, for food packaging and to the use of the spreading agent composition in a sterilising medium containing hydrogen peroxide for the sterilisation of packaging material or containers for food packaging.
- the food product as such is sterile to such a degree that micro-organisms do not multiply during long- term storage, that the filling of the product into the package takes place under aseptic conditions in clean machines in a clean environment, and that the package itself is capable of keeping the product unaffected by surrounding moisture, light, oxygen gas and bacteria for a long time. It is, of course, of highest importance that the packaging material or package is sterile, i.e. free from microorganisms, at the moment the food product is filled into it.
- Sterilisation of packaging machines, packaging material or packages to be filled may be achieved in various ways, e.g. by applying a chemical sterilising liquid or gas- phase mediums onto the surfaces to be sterilised, by UV-light or by electron beam irradiation or by combinations of such methods.
- a chemical sterilising liquid or gas- phase mediums onto the surfaces to be sterilised, by UV-light or by electron beam irradiation or by combinations of such methods.
- thorough cleaning in the first place and rinsing with sterile water also contributes significantly to the resulting aseptic environment in a packaging machine.
- Packaging containers of the single use disposable type for liquid and high- viscosity flowable foods are often produced from a packaging laminate of the type comprising a core layer of paper or paperboard and outermost liquid tight, heat sealable layers of polyolefin. Commonly occurring such packaging containers are marketed i.a. under the trademarks Tetra Brik Aseptic® or Tetra Classic Aseptic® and are principally employed for liquid foods such as milk, fruit juices etc.
- the packaging material in these known packaging containers is typically a laminate comprising a bulk core layer of paper or paperboard and outer, liquid-tight layers of thermoplastics.
- the laminate for these packaging containers is normally provided with at least one additional layer, most commonly an aluminium foil, which moreover renders the packaging material thermo-sealable by inductive thermo-sealing which is a rapid and efficient sealing technique for obtaining mechanically strong, liquid- and gas-tight sealing joints or seams during the production of the containers.
- an outermost layer applied to the aluminium foil, which outermost, inside layer may be composed of several part layers, comprising adhesive polymers and/or polyolefins.
- packaging containers are generally produced by means of modern packaging machines of the type that form, fill and seal packages from a web or from prefabricated blanks of packaging material.
- packaging containers are produced in that the web is reformed into a tube by both of the longitudinal edges of the web being united to one another in an overlap joint.
- the tube is filled with the intended liquid food product and is divided into individual packages by repeated transversal seals of the tube at a distance from one another below the level of the contents in the tube.
- the packages are separated from the tube by incisions in the transverse seals and are given the desired geometric configuration, normally parallelepipedic or tetrahedron-shaped, by fold formation along prepared crease lines in the packaging material.
- the web Before the formation of the tube and the filling of the product into the tube, the web typically passes through a bath with a liquid sterilising agent. So-called squee-gee rollers, remove the surplus of sterilising liquid by squeezing it away from the web, before the tube is dried with hot sterile air.
- squee-gee rollers remove the surplus of sterilising liquid by squeezing it away from the web, before the tube is dried with hot sterile air.
- Other methods of sterilising such a tube of packaging material are spraying, gas phase condensation or, most commonly, coating of the packaging material web with a roller, for applying the liquid evenly onto the surface of the packaging material web.
- H2O2 hydrogen peroxide
- H2O2 hydrogen peroxide
- sterilising agent which is suitable both for liquid and gas-phase sterilising mediums.
- H2O2 hydrogen peroxide
- other sterilising agents such as per- acetic acid are often used.
- the effect of the sterilisation is to a large extent depending on the ability of the sterilising medium to spread out evenly across the surface to be sterilised and on the wetting characteristics of the particular surface.
- the sterilising medium forms larger droplets and is not distributed evenly on the surface.
- the second problem is that residuals of sterilising medium will remain on the surface after sterilisation because the larger droplets are difficult to remove satisfactorily at high production speed in the packaging machine.
- the two problems are further pronounced at high speed production, because the sterilising agent then only has a minimum time to act on the surface to be sterilised and must be removed very quickly before the filling of the food product.
- the problem is also particularly pronounced when the surface to be sterilised is extra smooth and glossy such as is the case for certain film qualities used as an outermost layer of a packaging laminate.
- highly viscous products require an outermost material surface, directed towards the inside of the packaging container, onto which the viscous food product does not stick, in order to facilitate emptying of the package.
- the sterilising agent does not spread and remain evenly coated onto such a "non-stick" surface.
- a hydrogen peroxide-based sterilising medium that is more efficient and may improve the robustness of the sterilisation process, i.e. is less sensitive to variations in process conditions, and thus functions well also at higher production speeds of a packaging machine. More specifically, it is an object to provide a hydrogen peroxide-based sterilising medium that has an improved sterilisation effect.
- a specific object of a preferred embodiment of the invention is to provide a hydrogen peroxide-based sterilising medium that has an optimised sterilisation effect regarding wetting and consumption of the sterilising medium.
- a further specific object of the invention is to provide a hydrogen peroxide- based sterilising medium that leaves a reduced amount of residues on the surface after sterilisation.
- Yet a further object of the invention is to provide a hydrogen peroxide- based sterilising medium that functions well for smooth and glossy surfaces with low wetting ability.
- the hydrogen peroxide-based sterilising medium as defined in claim 1.
- Preferred embodiments of the sterilising medium of the invention are as defined in claims 2- 11.
- a sterilising medium containing an aqueous solution of hydrogen peroxide and a spreading agent additive composition comprising a compound selected from the group consisting of lecithin and chemically modified lecithin and further comprising a non-ionic emulsifier.
- the sterilising agent most commonly used is hydrogen peroxide due to its excellent killing effect on bacteria and its comparatively low cost and good health and safety characteristics in connection with food applications.
- Aqueous hydrogen peroxide solutions of concentrations of up to 50 weight-% are feasible for this invention and solutions of up to about 35 weight-% are commercially available for applications in food industry.
- a concentration of from 30 to 40 weight-%, most preferably of 35 weight-% is used in a sterilising medium according to the invention.
- Lecithin is regarded as a well tolerated and non-toxic surfactant. It is approved by the United States Food and Drug Administration for human consumption with the status "Generally Recognized As Safe” (GRAS) and is also approved by the EU as a food additive. In biochemistry, lecithin is usually used as a synonym for phosphatidylcholine, a phospholipid which is the major component of a phosphatide fraction which may be isolated from egg yolk or soy beans. Commercial lecithin, is a mixture of phospholipids in oil.
- the main phospholipids in lecithin from soya or sun flower oil are phosphatidyl choline, phosphatidyl inositol, phosphatidyl ethanolamine and phosphatide acid. To adapt the performance of lecithins, they may be chemically modified.
- Suitable chemically modified lecithins for the present invention are normally able to dispers more readily into water than crude lecithin and typically has an iodine value (I.V.) of less than 50.
- the iodine value is related to the number of ethylenic unsaturations in the molecule of the relevant substance.
- the chemical modification generally introduces hydrophilic substituents into the fatty acid ester group, which in turn renders the lecithin more hydrophilic.
- such chemically modified lecithins are hydroxylated or acetylated lecithins, saponified hydroxylated lecithin or saponified acetylated lecithin or mixtures thereof.
- Other chemically modified lecithins may be obtained by reactions with enzymes, such as lipase.
- a chemically modified lecithin according to the invention is hydroxylated lecithin.
- the non-ionic emulsifier is a polyoxylalkylene derivative of a fatty acid glyceride or a polyoxyalkylene derivative of a partial fatty acid ester or a hexitol anhydride or a mixture of such emulsifiers.
- polyoxyalkylene derivatives of partial fatty acid esters and hexitol anhydrides are POE (polyoxyethylene) 20 sorbitan monostearate, POP (polyoxypropylene) 20 sorbitan monostearate, POE 20 sorbistan tristearate, POE 10 sorbitan distearate, POE 15 mannitan monopalmitate, POE 10 mannitan dimyristate, POE 20 sorbitan dioleate, POE 20 sorbitan monooleate, POE 20 sorbitan trioleate, POE 20 galactitan monostearate, POE 20 galactitan dioleate, POE 30 sorbitan monostearate, POE 20 monolaurate, POE 20 sorbitan monopalmitate, POE 5 sorbitan monooleate and the like.
- Polyoxylalkylene derivatives of fatty acid mono- and diglycerides are according to the formula
- n represents an average number of repeating oxylkylene untis
- Y is either hydrogen or methyl
- the remaining R1 , R2 or R3 member of the Formula (I) composition is either hydroxyl, a polyoxyalkylene moiety or a fatty acid ester.
- the non-ionic emulsifier is an alkoxylated sorbitan fatty acid ester, and most preferably a polyethylene glycol 20 sorbitan fatty acid ester.
- a preferred, well functioning example is polyethylene glycol 20 sorbitan mono laurate, also called "TweenTM 20".
- the sterilising medium should preferably comprise from 0,1 to 0,4 weight-% of the unmodified or chemically modified lecithin. At above 0,4 weight-%, the sterilising medium becomes oily and more difficult to remove from the sterilised surface at drying. At below 0,1 weight-% of the lecithin, the consumption or uptake of the sterilising agent, i.e. hydrogen peroxide, becomes too low, i.e. too little hydrogen peroxide is transferred to the surface to be sterilised and the sterilisation effect is too low to be reliable.
- the sterilising agent i.e. hydrogen peroxide
- the lecithin compound is mixed with a non-ionic emulsifier, thus further improving the spreading and, preferably, the concentration of the non-ionic emulsifier should be from 0,1 to 0,3 weight-% in the sterilising medium.
- the sterilising medium comprises from 0,2 to 0,3 weight-% of the chemically modified lecithin and from 0,1 to 0,2 weight-% of the non-ionic emulsifier.
- the sterilising medium comprises about 0,3 weight-% of the chemically modified lecithin and from 0,1 to 0,2 weight-% of the non-ionic emulsifier.
- the spreading agent additive composition should most preferably comprise from 60 to 75 weight-% of the chemically modified lecithin and from 25 to 40 weight-% of the non-ionic emulsifier, calculated on the total weight of the spreading agent composition.
- the hydrogen peroxide-based sterilising medium according to the invention is prepared by first adding a spreading agent additive compound selected from the group consisting of lecithin and chemically modified lecithin to an aqueous solution of hydrogen peroxide or deionized water at a weight ratio of from 1 :5 to 1 :20, preferably at about 1 :10, stirring the mixture to obtain a stable emulsion, adding the thus obtained aqueous spreading agent lecithin emulsion to an aqueous solution of the hydrogen peroxide sterilising medium, at some stage adding a non. ionic emulsifier and finally stirring to obtain a stable hydrogen peroxide sterilising medium.
- a spreading agent additive compound selected from the group consisting of lecithin and chemically modified lecithin
- the non-ionic emulsifier is first added into the spreading agent additive lecithin emulsion to form a spreading agent additive composition.
- the non-ionic emulsifier may be added directly into the aqueous hydrogen peroxide sterilising medium in the form of a separate stable aqueous emulsion.
- the sterilising medium is applied by means of dipping the packaging material into a bath of the sterilising liquid.
- the sterilising medium is applied by means of coating the packaging material by means of a transfer roller transferring liquid sterilising medium from a bath of the sterilising liquid to the packaging material surface.
- the sterilising medium is applied by means of spraying of the liquid sterilising medium onto the packaging material surface to be sterilised.
- a spreading agent composition comprising a compound selected from the group consisting of unmodified lecithin and chemically modified lecithin and further comprising a non- ionic emulsifier, is used in an aqueous hydrogen peroxide sterilising medium for the sterilisation of packaging material or containers for food packaging.
- Fig. 1a is schematically showing how a web of a packaging laminate is led through a deep bath of a liquid sterilising medium in an aseptic packaging machine of the kind that is normally used for producing Tetra Brik Aseptic® packages
- Fig. 1 b is schematically showing such a packaging machine for the manufacturing of filled packaging containers from a packaging laminate in a continuous form, fill and seal process
- Fig. 2 is schematically showing how a web of a packaging laminate is led through a shallow bath of a liquid sterilising medium in an alternative sterilisation process
- Fig. 3 is schematically showing how a web of a packaging laminate may be coated with a sterilising medium by the sterilising liquid from a shallow bath via a transfer roller to one side of the web, in a further alternative sterilisation process
- Fig. 4 is schematically showing how a web of a packaging laminate may be coated with a sterilising medium by spraying the sterilising liquid onto one side of the web and, where appropriate, subsequently irradiating the surface to be sterilised with UV irradiation, in a packaging machine of the kind that is normally used for producing packages intended for chilled ESL (Extended Shelf Life) storage,
- Fig. 5a through 5j are showing UV photographs of the distribution or spreading of the sterilising medium liquid applied on a packaging material having a surface to be sterilised of very smooth blown film, by a standard application roller according to the method of Figure 2, above.
- the UV pictures are taken by including a fluorescent agent, i.e. Tinopal® into the sterilising medium.
- Fig. 6a, 6b and 6 c show the effect of the sterilising medium on the residual content of sterilising liquid when using the sterilising process as described in connection with Figure 2, above.
- Fig. 1a thus shows the principle of a packaging and sterilisation process 10 in which a web of packaging laminate is led through a deep bath 12 of a liquid sterilising medium in an aseptic packaging machine of the kind that is normally used for producing Tetra Brik Aseptic® packages.
- the hold time during which sterilisation takes place on the packaging material surface, is the total time during which the packaging material web is soaked in the bath of sterilising liquid. More or less immediately after the web exits from the bath, it is drained by so- called squee-gee rollers 13 of rubber, which squeeze the liquid away from the web, and subsequently it is dried by hot sterile air.
- FIG. 1b an example of a packaging machine 10b for the continuous high speed packaging of Tetra Brik® Aseptic packages is shown.
- the web of laminated packaging material is un-rolled from a reel 11 at the back of the machine, and led through a bath of sterilising liquid 12 just after applying a longitudinal seal cover strip 11 ' of thermoplastic polymer. After drying and evaporating off the sterilising liquid, the web is formed into a tube 14 which is longitudinally sealed and almost in the same operation filled 15 with the food product through a pipe 15 ' entering the top of the tube, transversally sealing of the tube beneath the surface of the filled food product and chopping off 16 the separate packages and finally folding and forming the packages into their final shape 17.
- a sterilising process 20 a is used, according to which the packaging material surface is not in direct contact with the liquid more than during a part of the total "hold time", i.e. the time during which the sterilising medium acts upon the surface, in that the packaging materia! web is dipped into a bath during a limited time, a so-called shallow bath.
- the experiments carried out as described hereinafter were made in a machine using this sterilisation system, by dipping the web of packaging material 21 into a shallow bath 22. Squee-gee rollers 23 are removing surplus of sterilisation liquid from the web and then the web is led through a heating chamber 25.
- the system is equipped with a special so-called blister roller 24 with a rough surface, which breaks down the liquid droplets on the packaging material surface to smaller ones, in the heating chamber 25.
- an extra heating and drying unit 26, with additional supply of heat and air flow, may be connected to the heating chamber 25.
- a sterilising process is used, according to which the packaging material surface is coated with sterilising medium by roller application, i.e. a transfer roller 33 transfers the liquid sterilising medium from a shallow bath 32 to the packaging material 31 surface.
- the coated surface is subsequently dried by a heating element (not shown).
- the intention may be to produce a packaging container with lower requirements on shelf storage life, such as packages for chilled ESL storage.
- Aseptic sterilisation methods are, however, also feasible involving spraying of sterilising liquid onto the packaging material surface to be sterilised.
- a web of packaging material 41 is led through a chamber 44, in which sterilising liquid is sprayed onto the entire surface of the web by means of a spray nozzle 42, and subsequently led past a UV-lamp 43 for irradiation of the same surface with sterilising UV-light, before the web is dried and then formed into a tube, filled and finally sealed into separate packages.
- a chemically modified lecithin that was used in the Examples is ALCOLEC® Aquasperse A from American Lecithin Company.
- This product is a hydroxylated lecithin which has water dispersibility characteristics.
- the lecithin remains oil soluble, but also becomes water dispersible and capable of forming oil-in-water emulsions.
- the modified lecithin was mixed with aqueous hydrogen peroxide or deionised water by using a mixer, or by shaking in a container with a tight lid, in order to obtain a stable emulsion. Then the diluted lecithin mixture dispersed readily into the hydrogen peroxide solution.
- Optical inspection of the wetting ability of the lecithin-containing sterilising mediums was made by the inclusion of a fluorescent agent called Tinopal® in the sterilising medium and UV photography of the coated surface.
- Various amounts of the modified lecithin and/or the non-ionic emulsifier polyethylene glycol 20 sorbitan monolaurate (TweenTM 20) was mixed with 35 weight-% aqueous solution of hydrogen peroxide according to Table 1. The concentration of Tinopal was 2 weight-% in all Examples.
- the UV photos in Figures 5a through 5j correspond to the respective Examples in the same order as presented in the Table.
- the first three Examples are Reference Examples, either comprising no spreading agent at all or only Tween 20.
- Examples 1-7 show that acceptable wetting is obtained when using the modified lecithin alone and at various concentrations and mixtures with TweenTM 20, but that optimised properties also as regards the consumption, i.e. the up- take of hydrogen peroxide solution, are obtained with the conditions according to Examples 2-4.
- “consumption” is meant the amount of sterilising agent that is carried by the web and passed through the squee-gee rollers and entered into the heating chamber. If the consumption is too low, evidently the sterilisation effect will be in-sufficient and un-reliable.
- the effect of the sterilising medium on the residual content on a sterilised surface was investigated and the results presented in Figures 6a - 6c.
- the well recognised Chemets® ferric thiocyanate method was used. According to this method, an ampoule with reagent, i.e. ferrous ion and ammonium thiocyanate in acid solution, is immersed into a package filled with deionised water. If any trace of hydrogen peroxide is remaining in the package at filling with deionised water, it will oxidize the ferrous iron in the ampoule to the ferric state and form a red thiocyanate complex. The red colour will have different shades depending on the concentration. For approval, the residual content should be less than 0,4 ppm. In the diagrams, the residual content in ppm, is shown by the Y-axis, while the time after start-up is shown on the X-axis.
- the measurements of residual content were made on packages at various points in time after start-up of the packaging machine (using a sterilisation system according to Figure 2 above), i.e. at 1, 30, 60, 90, 102 and 105 seconds after start-up, and 1 , 2 (3 packages),3,6,9,12,15,18,20 (2+5 packages),23,26 and 29 minutes after start-up. It can be seen that as the machine gets warm and the process reaches a steady- state, the residual content values stabilise at a lower level. Test runs were done at three different conditions, i.e.
