Peas et al. recommended maximum limits of 50 mgkg and 25 mgkg for putrescine and cadaverine, respectively. The concentration of putrescine in SCDS sample was over 25 mgkg, and 8 of 15 (53.3) samples had a higher level of cadaverine than this safe value, which might have a negative impact on human health. Thus, it is required to decrease.

A facile colorimetric method for rapid detection of putrescine (Put) and cadaverine (Cad) based on the peroxidase-like activity of (Fe,Co) codoped-CDs was developed. With the enzymatic hydrolysis by diamine oxidase (EC 1.4.3.6, DAO), Biogenic amines (BAs) were decomposed to produce H2O2 which oxidizes 3,3&x27;,5,5&x27;-tetramethyl-benzidine with the catalysis of (Fe,Co)-codoped CDs. By means of.

Cadaverine and putrescine can potentiate the toxic effect of histamine. Poisoning of BAs on the one hand depends on the amount that has entered the body and on the other hand also on the individual human sensitivity to each BA. The permissible concentrations of other BAs are greater than that of histamine. Therefore, e.g., doses of tyramine can.
