Good afternoon, I will. In the process of natural decay, plant fibers and nutrients will begin to decompose and produce ammonia nitrogen compounds. Common are nitrite and nitrosamine derivatives of pickled vegetables. Salt solution containing sodium chloride can only prevent microbial bacteria from breeding, but it will catalyze plants to produce more nitrite, such as sodium nitrite, which is harmful to human body. Please refer to as appropriate. The greater the salt content of pickled flavor side dishes, the more nitrite is catalyzed. If your celery is the appetizer I understand, please try to marinate it and eat it immediately, which is better for your health.
