加熱により餅の物性や食味が劣化し、また耐熱性や耐ガ
スバリアー性の包装材が高価である等の欠点があった。In general, molded rice cakes have a short shelf life due to bacteria that adhere to their surfaces (2), which can cause them to become moldy or rot. In order to preserve mochi for a long period of time, the mochi was packaged with heat sterilization by wrapping it in a gas barrier, or by wrapping it in a packaging material with gas barrier properties and enclosing a gas or oxygen scavenger. There were disadvantages such as deterioration in physical properties and taste, and the need for expensive packaging materials with heat resistance and gas barrier resistance.
本発明は、かかる欠点を解消しようとするもので、次に
その構成を添付図面に示す一実施例を参照して詳述する
。The present invention aims to eliminate such drawbacks, and its configuration will now be described in detail with reference to an embodiment shown in the accompanying drawings.

を特徴とするものである。The shaped mochi (1) is wrapped in a packaging material (2) that transmits ultraviolet light, and this wrapped mochi (3) is irradiated with ultraviolet light to make the mochi (
1), and the inner and outer surfaces of the packaging material (2) are sterilized.

を照射する場合を示している。Figure 1 is an explanatory diagram of a device for irradiating wrapped rice cakes (3) with ultraviolet rays.
) A lamp device (6) that emits ultraviolet light onto the belt conveyor is attached above (5), and the packaged rice cake (3) transferred on the higher belt conveyor (4) is transferred to the lower belt conveyor (5). ) and turn the packaged rice cake (3) over to irradiate the front and back surfaces of the packaged rice cake (3) with ultraviolet rays, and continuously apply ultraviolet rays (210 m to 328 meters) to the packaged rice cake (3).
The figure shows the case of irradiation.
また、殺菌条件は菌種及び生育の履歴により変動するが
、紫外線殺菌量≦：ついて一実験結果例を示すと次の表
の如くとなる。In addition, although the sterilization conditions vary depending on the bacterial species and growth history, the following table shows an example of the results of an experiment in which the amount of ultraviolet sterilization is ≦.
条 件 照射紫外線波長 ２５３．υ屡±１６ａｍのを
検体とし、紫外線の放射照度、照射時間をかえ行った。Conditions Irradiation ultraviolet wavelength 253. The irradiance of ultraviolet rays and the irradiation time were varied using υ屡±16 am as specimens.

がわかった。As shown in the above table, it was found that more than 99% of the microorganisms on the order of 10" attached to the rice cake surface could be sterilized by irradiation with ultraviolet light of 1QQaqh" for 2 to 5 seconds at an illuminance of 50 mψ.

。In the present invention, the rice cake (1) formed as described above is packaged using a packaging material (2) C2 that transmits ultraviolet rays, and the wrapped rice cake (3) is irradiated with ultraviolet rays. The ultraviolet rays pass through the material (2) and sterilize the surface of the rice cake (1) and the inner surface of the packaging material (2), and the ultraviolet rays directly sterilize the outer surface of the packaging material (2), eliminating bacteria attached to the wrapped rice cake (3). is sterilized, the packaged rice cake (3) becomes substantially sterile, and can be stored for a long period of time.

ガスバリアー性の包装材に比し安価であるためこの分低
廉シー包装餅（３）を製造し得ることとなる。Moreover, since the packaging material (2) that allows ultraviolet rays to pass through is cheaper than the packaging material that is heat resistant and gas barrier resistant, it is possible to produce the sea-packed rice cake (3) at a lower cost.
