Which fruit has the most cyanide?
Fruit and vegetables that produce cyanide
These fruits include apricots, cherries, peaches, pears, plums and prunes. The flesh of the fruit itself is not toxic. Normally, the presence of cyanogenic glycoside alone is not dangerous.

What seed has the most amygdalin?
Plum seeds
Amygdalin is most abundant in Plum seeds, especially the Green and Black Plums; amygdalin content of Plum seems highly dependent on variety (Table 1). The values reported in this study was similar to the amygdalin content of Plum kernels (12.7 mg/g) reported by Haque & Bradbury (2002).
What does cyanide do to the body?

Preparation. If you want to get the flavor from noyaux but are concerned with the quantity of amygdalin, roast the whole pits in a 350 F oven for 10 to 15 minutes. This helps neutralize the amygdalin, and also makes the shells of the pits more brittle, which makes them easier to crack to get the kernels within.
What is commercial name of amygdalin?
