Description

Providing the scientific background on the risk and safety assessment of toxicity in phytochemicals in everyday food, this monograph contains the pros and cons of 20 testing methods, with comments by the internationally acknowledged and independent DFG Senate Commission on Food Safety.
Supplemented by 40 poster contributions on phytochemicals and their effects.
