Hi there,

Strong base cause breaks down of fat molecules.

Saponification is a process in which fat molecules react with a strong base (NaOH or KOH) to give glycerol and salts of carboxylic acid. The saponification is useful in the preparation of soaps. Saponification requires a strong base to convert the fat molecules into the glycerol and carboxylic salts.
