 Principle
When cut fruit or vegetables become brownly coloured within a short time, this colour change is known as "enzymatic browning". "Enzymatic browning" can be prevented by adding acid or reducing agent, as well as by excluding oxygen. Vinegar or lemon juice are old household remedies, which prevent the discolouration of fruit when it is preserved.
