Abstract
The utility model relates to a high-pressure nitrogen fresh-keeping container comprising an airtight shell body. A storage space is arranged inside the airtight shell body. A product in need of fresh keeping is placed in the storage space of the airtight shell body and high-pressure nitrogen is filled in the storage space of the airtight shell body. The pressure intensity of the high-pressure nitrogen in the storage space is from 0.01 kg/cm<2> to 8 kg/cm<2>. The pressure intensity of the high-pressure nitrogen is set according to the compression resistance degree of the product in need of fresh keeping. The pressure intensity of the high-pressure nitrogen in the storage space is preferably from 0.5 kg/cm<2> to 1.5 kg/cm<2>, so that vast majority of bacteria can be killed, the bacteria can not grow, fresh-keeping effect is good and pressures on the high-pressure nitrogen fresh-keeping container and the product in need of fresh keeping can be reduced. The high-pressure nitrogen fresh-keeping container is capable of prolonging the quality guarantee period several times and simple in structure. The nitrogen fresh-keeping method is oxidation resistant and the high pressure can kill microbial bacteria. The higher the pressure is, the more the bacteria can be killed. The higher the pressure of the nitrogen is, the lower temperature is, so that better fresh-keeping effect is achieved.
