First of all. Nitrite is a kind of food additive, which is mainly used as colorant and preservative. Lz is fine as long as the addition amount is within the specified limit. Secondly, the coloring function of nitrite is used in red meat (you can see from the color that pork, beef and tuna are all red meat. Chicken and common fish are white meat. ) in the product. Is to prevent red meat from discoloring. As long as lz buys qualified products, it is no problem to eat them regularly.

Hope to adopt
