Definitions

  • the present invention relates to a method for producing a packaged drink, in particular a packaged drink such as a packaged tea drink and a packaged acidic drink.
  • Hot pack methods and aseptic methods are conventionally known methods for producing packaged drinks of low acidic drinks such as green tea drinks or the like, or acidic drinks such as drinks with fruit juice or the like that are packaged in, for instance, PET bottles.
  • the drink for instance is thermally sterilized at conditions equal to or exceeding 120° C. and 4 minutes, for low acidic drinks having a pH of 4.6 or higher such as tea drink or the like, and conditions equal to or exceeding 85° C. and 30 minutes for acidic drinks having a pH of 4.6 or lower, the content being then filled, with the liquid temperature kept at 65° C. to 90° C., into washed containers that are then sealed, the containers being sterilized herein by the heat of the content.
  • the containers are turned upside down immediately after sealing, and the cap inner surface and so forth are sterilized by coming into contact with the liquid, in what is called overturning sterilization.
  • hot water is sprayed onto the outer peripheral face of the containers in a pasteurizer, to carry out thereby thermal sterilization at 75° C. over 3 minutes.
  • the containers are cooled down to room temperature (see Patent document 1 for an example of this method).
  • Hot pack methods are highly problematic in that the content is kept at a high temperature, of 60° C. or above, over a long time, with the content being filled in that state. As a result, the content may undergo thermal deterioration, which may result in rapid loss of taste and flavor. Moreover, the surface of the container is brought into contact with the high-temperature drink during filling, and hence the containers must be heat-resistant, which necessitates a heat resistance treatment in the case of, for instance, PET bottles. Moreover, negative pressure develops in the interior of the containers after cooling, and thus the containers must be made thick-walled so as to ensure sufficient strength to withstand that negative pressure. The foregoing drives up thus the cost of the containers, which is a drawback.
  • hot pack methods suffer the drawback of increased equipment space and higher equipment costs brought about by the need for large-scale pasteurizers for post-sterilization and cooling. From the viewpoint of running costs, pasteurizers are also problematic in that they require large amounts hot water, which entails greater water consumption and higher energy costs.
  • the drink which has been sterilized beforehand at high temperature for a short time using a means such as a heat exchanger or the like, followed by cooling, is sterilized with a chemical agent such as hydrogen peroxide, peracetic acid or the like.
  • a chemical agent such as hydrogen peroxide, peracetic acid or the like.
  • the drink is filled and sealed then, at room temperature and in an aseptic environment, into containers which need not be heat resistant and that have been washed with aseptic water.
  • This method can ensure sealing in wholly aseptic conditions, and hence the method is adequate for filling, even at room temperature, not only acidic drinks or tea but also milk-containing drinks in which spore-forming bacteria, such as Clostridium botulinum or the like, proliferate readily.
  • aseptic filling is thus advantageous in that it entails little thermal deterioration of contents, it requires a sterilizing chemical agent and a chemical agent treatment device for sterilizing the containers. Aseptic filling requires also, for instance, large amounts of aseptic water and a washing device for washing the containers. Aseptic filling is thus a large-scale operation involving various equipment for carrying out the above steps, as well as a clean room and ancillary controls. The method is hence problematic in terms of the substantial equipment cost and running costs associated therewith.
  • Patent document 2 a novel hot pack method as a method for solving the above problems of conventional hot pack methods and aseptic filling methods.
  • This novel method involved thermally sterilizing a green tea drink comprising 30 mg % or more of catechins at a pH of 4.6 or higher or an acidic drink having a pH below 4.6; keeping thereafter the drink at a temperature of 60° C. to 70° C.; thermally sterilizing and washing at least the inner surface of a container with worm water at 65° C. to 100° C.; filling the drink into the sterilized container, at a filling temperature of 60° C.
  • This method does not require a post-sterilization step after filling and sealing, and hence no large-scale equipment in the form of pasteurizers need be employed.
  • the method is advantageous in allowing reducing equipment costs and running costs as compared with conventional hot pack methods, and in allowing easing the conditions relating to container resistance against vacuum deformation.
  • the method is problematic in that it requires a cooling step after sealing, and results in loss of taste and/or flavor, brought about by content thermal deterioration, although to a lesser extent than in conventional hot pack methods. Also, the method cannot obviate the need for the containers to be resistant to vacuum deformation.

  • Lowering the filling temperature is an effective way of solving the above-described shortcomings of conventional hot pack methods.
  • microbial contamination remains a possibility on account of small parts such as liquid-feeding pumps, packings, joints and so forth, in the liquid-feeding system from the storage tank to the filling machine, that are ordinarily used in filling equipment, while from the viewpoint of product safety, it has not been possible heretofore to lower the filling temperature below that in the above-described prior art documents.
  • the inventors perfected the present invention upon finding that content sterilization by chemical agent becomes unnecessary, and that the content can be filled at room temperature through quick cooling after quick thermal sterilization, by restricting the content drink to drinks in which growth of spore-forming bacteria is difficult after heating, for instance a tea drink such as Oolong tea or green tea comprising 30 mg % or more of catechins at a pH of 4.6 or higher, and an acidic drink having a pH below 4.6, and upon finding that content sterilization by chemical agent becomes unnecessary, and that the content can be filled at room temperature through quick cooling after quick thermal sterilization, by making the liquid-feeding pathway of the content liquid, from thermal sterilization of the content to filling thereof, into a sterilized wholly closed space, and by maintaining a clean environment, isolated from the outside, in which containers and the filling and sealing environment are sterilized with worm water.

  • the drink to be filled is thermally sterilized up to a predetermined sterilization value and is thereafter quickly cooled to room temperature, the cooled drink being stored in the storage tank, and wherein a content liquid is fed to the filling machine to make the liquid-feeding pathway into a closed liquid-feeding pathway into which outer air does not intrude, and the surrounding environment is made an environment-controlled space isolated from the outside, such that the drink is filled at room temperature into the sterilized container and then sealed in the environment-controlled space.
  • Another invention of the present application is the above method for producing a packaged drink, wherein the drink is a drink comprising 30 mg % or more of catechins at a pH of 4.6 or higher, and the drink is thermally sterilized to a sterilization value equal to or higher than that of thermal sterilization at 135° C. and 7.58 seconds.

  • Another invention of the present application is any of the above methods for producing a packaged drink, wherein the environment-controlled space is a space housed in a box.
  • a further invention of the present application is characterized in that the storage tank is kept at positive pressure with sterile gas, and the liquid is fed from the storage tank to the filling machine through pressure-feeding by sterile gas.
  • Another invention of the present application is the above method for producing a packaged drink, wherein washing which is performed after thermal sterilization and washing of the surrounding environment using a chemical agent has also a sterilizing function by using hot water at 65° C. to 100° C.
  • Another invention of the present application is the above method for producing a packaged drink, wherein any of a peracetic acid chemical agent, hydrogen peroxide, an ozone-based chemical agent, and a chlorine-based disinfectant containing hypochlorous acid is used as the chemical agent for sterilizing and washing beforehand the surrounding environment where a container and a cap are sterilized, washed, filled and sealed.
  • the method for producing a packaged drink of the present invention enables room-temperature filling of, for instance, acidic drinks such as fruit juice drinks, as well as tea- or milk-containing drinks or the like, without the need for containers, equipment and the environment to be sterilized with a chemical agent solution or washed with sterile water, as is the case in aseptic filling methods.
  • the invention allows thus obtaining a good packaged drink, as afforded by aseptic filling methods, without flavor loss due to content thermal deterioration, which occurs in hot pack methods.
  • the method of the present invention moreover, resorts to simpler equipment than aseptic filling, and uses no chemical agent solution. Hence, the method of the present invention affords substantial savings in equipment costs and running costs while increasing the efficiency and speed of the production line.
  • the containers need not be heat-resistant or resistant to vacuum deformation, and thus the walls of the containers may be thinner, which allows reducing container costs.
  • the method of the present invention moreover, requires no post-sterilization or cooling after sealing, and hence equipment is simpler than in hot pack methods.
  • the method of the present invention requires no large amounts hot water, and allows thus reducing equipment and running costs while increasing line speed.
  • the products moreover, can move onto inspection, box packing and so forth immediately after filling and sealing, which allows increasing line efficiency while achieving energy savings.
  • the use of chemical agent is restricted, in the case of acidic drinks such as fruit juice drinks, as well as tea- or milk-containing drinks or the like, to the step of sterilizing and washing the surrounding environment, in which the containers are washed, filled and sealed, that is carried out prior to filling.
  • room temperature filling becomes possible without the need for large amounts of chemical agent solution, sterile water and so forth, as is the case in aseptic filling.
  • the method of the present invention allows thus obtaining a good packaged drink, as afforded by aseptic filling methods, with little flavor loss due to content thermal deterioration, which occurs in hot pack methods.

  • the drink is quickly cooled down to room temperature after sterilization, and therefore, the method of the present invention allows mitigating thermal deterioration and preserving flavor, in addition to the above effects.
  • the environment after filling and sealing is an environment where spore-forming bacteria cannot survive, and hence sterilizing and washing the containers with hot water prior to drink filling does away with the need for sterilization after filling using a pasteurizer.
  • the drink is an acidic drink having a pH below 4.6, thermally sterilizing the acidic drink to a sterilization value identical to or higher than 85° C. and 30 minutes allows inhibiting bacterial growth after sealing, besides the above effects. Also, the drink is quickly cooled after thermal sterilization, which allows preventing flavor and component deterioration. Moreover, sterilizing and washing the container with hot water prior to drink filling does away with the need for sterilization after filling using a pasteurizer.
  • liquid can be feed without using pumps, in which small parts are difficult to sterilize, by pressure-feeding the liquid from the storage tank into the filling machine by means of sterile gas.
  • This facilitates sterilization of the liquid-feeding mechanism, while positive pressurization allows preventing outer air from intruding into the path, which allays the concern of the drink being contaminated with outer air.
  • hot water has also a sterilizing function, when used at 65° C. to 100° C. for washing the surrounding environment, after sterilization thereof with a chemical agent.
  • a chemical agent used at 65° C. to 100° C. for washing the surrounding environment, after sterilization thereof with a chemical agent.
  • this allows the chemical agent to be used at a lower temperature than is the case in, for instance, aseptic filling, and allows curbing thereby breakdown of the chemical agent, and increasing the number of times that the chemical agent can be reused, while reducing damage inflicted on the equipment.
  • the sterilizing effect against heat-resistant spore-forming bacteria is also enhanced.
  • the surrounding environment in which containers and caps are sterilized, washed, filled and sealed, is sterilized and washed beforehand using a specific chemical agent. A yet more reliable sterilizing effect is achieved thereby.
