BY Mamie Doris 2018-05-14Cans that have been left for too long can cause food spoilage and gas production due to internal microbial growth or corrosion of the tinplate. The performance that can be seen by the naked eye is that the cans swell and gain weight. You can find out whether there is "fat listening" phenomenon in canned food by tapping and observing, to identify whether the storage has deteriorated. It is normal for aerated canned food to appear "fat listening" in low-pressure areas of the plateau.4
