Abstract

(57) [Abstract] [PROBLEMS] A sterilized food storage bag for sterilization for preventing food from being contaminated from the storage bag. SOLUTION: A synthetic resin bag for preserving foods that has been sterilized by radiation treatment so that the number of viable bacteria is 1 × 10 ³ or less. Further, as the material for forming the bag for storing food for food preservation, the synthetic resin film itself may contain a bactericide, or a film having a coating material containing a bactericide arranged on its surface may be used.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention mainly relates to a relatively small-sized synthetic resin bag such as polyethylene, which is sterilized to store food for inspection.

[0002]

[Prior art]

 If the food hygiene management standard requires a certain number of cooks or more, it is necessary to store foods that have already been cooked and eaten for a specified period of time, assuming that the source of food poisoning is identified. Mandatory. However, based on the current food hygiene management and operation standards, the inspection of food is “put about 50g of each raw material and cooked food in a clean container (plastic bag, etc.) and store at -20 ° C or below for 2 weeks or more. However, there is no conventional container that is provided with its body sterilized in advance as a container made of synthetic resin or metal for storing this inspection food.

[0003]

[Problems to be solved by the device]

It is an object of the present invention to provide a synthetic resin bag for storing inspection foods, which is made of a synthetic resin film and is characterized in that the number of surviving bacteria of general bacteria is sterilized by irradiation to 1 × 10 ³ or less.

[0004]

[Means for Solving the Problems]

 Irradiation is performed, for example, in the irradiation chamber while the synthetic resin bag made of synthetic resin film for food preservation passes through the source assembly (maximum 37 PBq, 1 million Ci) on the slat conveyor, and the dose is adjusted. Is performed by increasing or decreasing the conveyor speed, and irradiation dose of about 15 kGy is sufficient. Radiation for this sterilization treatment is not limited to γ-rays and may be X-rays or electron beams, and the irradiation method or irradiation dose is not limited to the above.

The present invention will be described below with reference to the accompanying drawings. 1 and 2 are plan views of a synthetic resin bag provided by the present invention, in which 1 is a synthetic resin bag, 2 is a bag opening portion, 3 is a bottom seal portion, 4 is a printing portion, and 5 is a synthetic portion. A resin bag, 6 is a bag opening, 7 is a bottom seal part, 8 is a printing part, and 9 is a gusset part. An example of the bag size is a width of about 140 mm, for example 210 mm and a thickness of about 0.04 mm. Of course, the size is not limited to this, and may be larger or smaller than this. In the present invention, first, referring to FIGS. 1 and 2 as an example, 100 bags of this bag are put into an appropriate outer bag (made of synthetic resin) and sealed (FIG. 3), and γ-ray or X-ray irradiation is performed. Sterilize by. As a means of sterilization, a synthetic resin bag in which an antibacterial agent has been kneaded or coated on the inner surface can also be used.In this case as well, put 100 sheets in the outer bag (made of synthetic resin), and put 100 sheets in the outer unit. It is possible to seal any number of sheets without being limited to.

[0006]

[Effect of the invention]

The present invention provides a synthetic resin bag for food preservation, which is made of a synthetic resin film and is characterized in that the number of surviving bacteria of general bacteria is sterilized to 1 × 10 ³ or less by irradiation or use of a bactericide. In addition, it is possible to prevent contamination of the food from the food container with bacteria and to accurately inspect the food itself. In addition, since each 100 sheets are stored in the outer bag, the storage space can be used efficiently and it is easy to carry. Furthermore, conventional containers for storing food samples have been washed and sterilized after use, but this is practical because it saves the labor.
