Abstract: Fresh chicken eggs were used to prepare lead-free preserved eggs. The effect and mechanisms of KOH on pH and color of albumen and yolk as well as the texture profile analysis (TPA) of preserved chicken eggs were investigated. The results indicated that adding 5.5% KOH during the pickling process could provide excellent sensory quality and texture properties for preserved chicken eggs. This investigation can provide theoretical guidance for the manufacturing of K+ type lead-free preserved eggs.

Key words: K+ type lead-free preserved eggs, curing solution alkalinity, color, textural property
