The nutritional value of preserved eggs comes mainly from the nutritional components of the preserved eggs themselves. They are rich in high-quality protein, which is unique to eggs. Every 100 grams contains about 14 grams. After being pickled in alkaline conditions, part of the protein is broken down into amino acids (such as glutamic acid), which makes the flavor more prominent and has a higher digestion and absorption rate. It can provide the body with the basic nutrients needed for tissue repair and immune function.
