1. The main components of common alkali are sodium carbonate and salt; The main component of baking soda is acid salt. When squid is dried by alkali, its original structure is destroyed by the corrosion of alkali, so that it can absorb water to the maximum extent, restore its original characteristics and facilitate digestion and absorption; Ordinary alkali does not have these characteristics and cannot replace edible alkali for dry goods distribution.
