Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for producing sterilized kamaboko that has a long shelf life.

In the production of kamaboko with boards, etc., steaming is usually carried out using steam at a temperature of approximately 80°C. At this steaming temperature, common bacteria among the attached microorganisms are killed, but Bacillus
It is difficult to kill all the spores and mold spores, so if you look at the product outlet from the steamer, you will find that many spore bacteria remain.

Furthermore, depending on the temperature conditions, it may be difficult to kill common bacteria by steaming.

For this reason, the industry has frantically controlled the temperature of steaming to completely kill all common bacteria, while special sterilization treatments have been applied to sterilize spores and mold spores.

Among them, the most effective method was to spray water and then hydrogen peroxide at the product outlet of the steamer, but recently a VC was introduced (from January 15, 1980). Due to safety concerns, the use of hydrogen peroxide has been discontinued.

In addition, attempts have been made to use ultra-high-power germicidal lamps, but the irradiation time requires at least 40 seconds, and even with this irradiation time, there is a problem that bacteria that have entered the interior and shadowed areas are not completely sterilized. 1. Therefore, the reality was that unless chemicals were used, there was no way to take measures against the spores and mold spores in kamaboko.

The present inventor conducted various studies to overcome the drawbacks of the conventional kamaboko sterilization method, and as a result, discovered that the purpose could be achieved by using ozone.Based on this knowledge, the present inventor developed the present invention. It has been completed.

That is, in the present invention, after steaming kamaboko, the kamaboko is washed with a water shower, and at the same time, irradiated with sterilizing light from an underwater sterilization lamp to carry out cleaning and sterilization treatment, and then passed through an ozone atmosphere to cool and sterilize the fish. To provide a method for producing kamaboko, which is characterized in that kamaboko is sent to a packaging process under aseptic conditions and packaged while maintaining a sterile state.

The method of the present invention will be explained according to the illustrated embodiment. 1 is an automatic steamer in which kamaboko with a board is steamed at about 80°C.

Since this steamer 1 itself is well known, it will not be described in detail.

The kamaboko with a board is filled in a gondola 2, and after passing through the steamer 1, it enters the next cleaning and sterilization process through an exit 3.

4 is a cleaning sterilization room, 5 is a water shower, and 6 is an underwater sterilization lamp.

In this case, the water in the water shower 5 is naturally sterile water, but
This is not sterile water as defined in the Water Supply Law, but completely sterile water.

Such completely sterile water can be obtained by sterilizing tap water using a normal running water sterilizer (ultraviolet sterilizer).

In this cleaning sterilization room 4, there is a process for dispersing fallen bacteria by water splashing,
A stainless steel cover (not shown) will be installed to prevent the effects of ultraviolet rays on the human body.

The processing conditions in the cleaning and sterilizing chamber 4 vary depending on the production rate of kamaboko, etc., and the irradiation conditions of the sterilizing lamp, the amount of washing water, etc. can be appropriately set according to these processing conditions.

Next, the kamaboko that has been washed and sterilized is sent to a cooling sterilization process.

7 in the figure is a cooling machine, and the kamaboko in the gondola is cooled while going around the machine, and at the same time is sterilized by the oso in the atmosphere.

Cold air is blown into this cooling device 7 according to a conventional method.

8 is a cold air inlet, and 9 is a cold air outlet.

The concentration of ozone is not particularly limited, but is preferably 0.2
~0.5 ppm.

Reference numeral 10 indicates germicidal lamps installed at the inlet 11 and outlet 12 of the cooling device 7 (for example, a 30 W germicidal lamp).

In addition, sterilizing lights will be installed on the ceiling etc. inside the cooling unit.

The germicidal lamp 10 is covered with a cover to prevent ultraviolet rays from affecting humans, and to prevent bacteria from entering from the outside.

Furthermore, the germicidal lamp 10 has the function of decomposing and extinguishing ozone leaking from the cooling machine.

Ozone contained in the atmosphere of the cooling machine γ can be generated by a known pure ozone generation method.

13 is this ozone generator.

In this way, a sterile kamaboko with a plate suitable for packaging is obtained.

This kamaboko is then sent to a packaging process and wrapped to become a product.

This packaging process is also maintained in a sterile state as follows.

That is, the kamaboko 14 taken out from the gondola 2 coming out of the cooling machine 7 is sent to the packaging machine 16 under irradiation with the sterilizing lamp 15.

In addition, the surroundings of the packaging machine 16 and the process leading thereto are covered with glass or vinyl chloride resin film, and the ozone concentration at night is raised to 1 ppm and maintained overnight.
Mesophilic bacteria, psychrotrophic bacteria, mold (white mold, blue mold, black mold)
Before starting work, the generation of ozone is stopped and the germicidal lamp or high-output lamp 17 above the packaging machine is turned on to eliminate the presence of microorganisms such as Rapidly decomposes and eliminates high concentrations of ozone,
Next, the packaging work is performed.

Strict hygiene management will be carried out at this time.

Note that 18, 19, and 20 are transfer conveyors.

In order to solve the problem of corrosion of rubber cords, rubber backings, and metals due to high concentration of ozone, between the above-mentioned cooling machine 7 and packaging machine 16, silicone 2410 (for metal), silicone 2411 (for rubber) ( Both were manufactured by Toray Silicon Co., Ltd.).

According to the method of the present invention, no drugs are added,
Therefore, sterile kamaboko with a long shelf life can be efficiently produced without the risk of secondary contamination.

Furthermore, the method of the present invention has the advantage that it can be implemented by only partially improving the conventional manufacturing process.

When the kamaboko with a plate obtained by sterilizing and packaging according to the method of the present invention was left in a heated room at room temperature, there was no change even after one month, and there was no problem in eating it.

Incidentally, in this case, the kamaboko with a board that was packaged in a packaging process that was not allowed to cool in ozone and was not specifically sterilized by ozone became inedible after a few days when left under similar conditions.
