Problems solved by technology

According to the method disclosed in the above-mentioned Patent Document 1, the contamination or proliferation of bacteria or microorganisms adhering to the food is reliably suppressed, and the storage period of the food becomes longer.
However, since it is necessary to generate negative ionized air frequently, cost and electricity are also required. In addition, depending on the food, it is also considered that it will be dry and taste bad due to the frequent wind of negative ionized air.

Embodiment 2

[0040] figure 1It shows the case of irradiating positive ions and negative ions from one part, placing edible meat at the position where the positive ions and negative ions meet and storing it for a certain period of time (Example 1: black dots) and the case of not irradiating positive ions and negative ions ( Comparative example 1: the coordinate diagram of the white square) for comparison, figure 1 (a) represents the curve connected by the values ​​at each time point, figure 1 (b) means based on figure 1 Indices calculated from the results of (a). exist figure 1 Among them, the vertical axis represents the average number of bacteria Log(CFU / cm 2 ), figure 1 The horizontal axis of (a) represents each time point at the initial stage, immediately after irradiation, 4 days later, 7 days later, and 10 days later, figure 1 The horizontal axis of (b) represents the number of elapsed days. in addition, figure 2 It shows the case of irradiating positive ions and negat...

Embodiment 1

[0071] here, Figure 9 is a diagram schematically showing the ion irradiation device 51 used in Example 1, respectively Figure 9 (a) schematically shows the accommodating part 52, Figure 9 (b) schematically shows the ion generating part 54 attached to the cover part 53 of the storage part 52, Figure 9 (c) schematically shows a state where positive ions and negative ions are being irradiated from the ion generating unit 54 to the edible meat 55 accommodated in the storage unit 52 . in addition, Figure 10 It is a figure which schematically shows the procedure of Example 1. In Example 1, first as Figure 10 As shown, the edible meat 55 (beef ribs of about 300g in particular) is placed on the shallow chassis 56, and the bacteria attached to the surface of the edible meat 55 are wiped with a bacteria extraction stick (cotton swab) 57a, and the bacteria attached to the bacteria extraction stick The bacteria were diluted with sterilized water and spread on standard agar medi...

Embodiment 3

[0094] Figure 12 is a diagram schematically showing the ion irradiation device 71 used in Example 3, Figure 12 (a) shows the cover part 63 and the ion generating part 64, Figure 12 (b) has shown the state which attached the cover part 63 to the storage part 62. As shown in FIG. Figure 12 The ion irradiation device 71 shown is used with Figure 11 The same ion generating part 64 is shown, but it is different in that not only is the ion generating part 64 installed on the outside of the cover part 63 to irradiate positive ions and negative ions from the upper side, but also surrounds the storage part 72 and is placed on the front, rear, left, and right lower sides. The same ion generators 64 are also respectively provided to irradiate positive ions and negative ions to the internal space of the storage portion 72 . Additionally, when using Figure 12In the case of the ion irradiation device 71 shown in (b), the edible meat 55 is placed on the net or the grid 73 so that p...

Abstract

Provided are: a method for storing meat stored in a refrigerator or a freezer after being subdivided from a block, the method being characterized in that the meat is irradiated with positive ions and negative ions prior to storage in the refrigerator or the freezer; a method for delaying the expiration date of a food item that requires refrigerated storage; and a method for suppressing multiplication of microbes occurring on the surface of a food item that requires refrigerated storage. Also provided are a method capable of suppressing multiplication of microbes adhered to a food item (in particular, meat) that requires refrigerated storage using an ion irradiation device suitable for use in the above methods, a method for thereby delaying the expiration date of a food item that requires refrigerated storage, and a device suitable for use in the above methods.

Description

technical field [0001] The present invention relates to a storage method for edible meat, a method for extending the shelf life of foods requiring refrigeration storage, and a method for suppressing the proliferation of bacteria generated on the surface of foods requiring refrigeration storage. Moreover, this invention relates to the ion irradiation apparatus which can be suitably used for the method of this invention mentioned above. Background technique [0002] In stores dealing with food such as supermarkets, the shelf life of edible meat is important especially from the viewpoint of safety. This shelf life has a lot to do with the spoilage of food. Even foods with little microorganisms attached to the surface in the initial stage can become contaminated by mechanically or manually attaching bacteria to the surface during processing. When the bacteria adhere in this way, the bacteria proliferate on the surface of the food, thereby spoiling the food. Therefore, the num...
