1. Can basic copper sulphate be used to preserve preserved eggs?
According to relevant regulations, food-grade must be used.
The biggest difference between industrial basic copper sulphate and food additive basic copper sulphate is that industrial basic copper sulphate usually contains toxic and harmful elements such as lead, arsenic, and cadmium. If it is used to process salted duck eggs, it will cause harm to the human body. In addition to the low price of industrial basic copper sulphate, another reason is that industrial basic copper sulphate is used to soak preserved eggs, which can shorten the production time of preserved eggs. It takes two months to process preserved eggs. It only takes one month to use industrial basic copper sulphate.
