 aflatoxin 


how to detect?

chemical paper test strip 

UV 

The aflatoxins all have absorption maxima around 360nm with a molar absorptivity of about 20,000: the B toxins are named for their blue fluorescence (425nm) and the G toxins for their green-blue fluorescence (450nm). The B1 toxin is the most common, flowed by B2 toxin, while the G toxins are fairly rare. The fluorescence sensitivity of the G toxins is more than 10 times greater than that for the B toxins. The minimum detectable level is about 100 pgrams for the G toxins and 1 ngram for the B toxins

NB: MADE IN ITALY 是否真正 意大利制造實在無從考 証
