Authenticity analysis of lemon juices concerning the adulteration with lime

Adulterations of fruit juices with foreign fruits are always in the public focus, therefore the proof of fruit juices’ authenticity is unavoidable.

Therefore, it is up to the chemical laboratories to provide methods which evaluate the authenticity of lemon juices and even support with a statement about the amount of added lime.
