Can’t eat it.

The moisture content of plant seafood such as kelp and seaweed is low enough to prevent the proliferation of bacteria; the fat content is also low, and the oxidative rancidity of the oil will not cause unpleasant odors such as flaky smell. During the storage process, nutrients such as vitamins will be slowly oxidized, so they need to be stored in sealed bags or cans to help prevent moisture absorption and deterioration. Just store it in a cool, ventilated and dry environment. No need to put it in the refrigerator. The shelf life can be up to two years.

Although dry goods have a relatively long shelf life, it is best to buy them now and eat them now. It should be reminded that it is often difficult to judge whether dry food has gone bad with the naked eye. It is best to smell it before eating. If plant-based dry goods are found to have a musty smell, it means mold has occurred; seafood dry goods have an ammonia smell, a havoc smell, etc., which means that the protein has been decomposed under the action of microorganisms, and the oil has become oxidative and rancid. If these phenomena occur, do not eat it anymore. .
