Serious toxicity and death is possible with large doses. Purportedly, as much as a cupful of apple seeds would be required to cause death in an adult.

How much amygdalin is in apricot kernel?
Apricot seeds have higher amygdalin content and comparatively easy deliver hydrogen cyanide than apple and peach. Amygdalin concentration of apricot varies between 0.1 and 4.1 mg/g as well as on the growing area and bitterness of seeds.
How many apricot seeds is too many?
The FSAI advises that apricot kernels should be labelled to inform consumers that adults should eat no more than 1-2 small kernels per day due to the risk of cyanide poisoning.
What has the most amygdalin?
green plums
The pits of green plums have the highest amygdalin content, followed by apricots, black plums, peaches and red cherries, one study found. Apple seeds were next on the list.
How long does it take for amygdalin to convert to cyanide?

How do you neutralize amygdalin?
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 happens if you swallow apricot seed?

What does B17 do for your body?
It may provide pain relief: Older research on rats indicates that amygdalin may help relieve pain. However, there is a lack of human-based evidence to suggest the effectiveness of amygdalin as a pain-reliever. It may improve immunity: A 2020 study suggests that vitamin B17 may help increase immunity.
Is amygdalin destroyed by heat?
The enzymes usually act at temperature of about 20-40oC and can be destroyed at higher temperature. Enzymatic hydrolysis of amygdalin in plant foods takes place within 30 min to 6 hr depending on the degree of maceration of the food sample (Tunçel, Nout & Brimer, 1995).

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 does amygdalin taste like?
Amygdalin has a bitter taste. In stone fruits like plums (Prunus domestica), cherries, peaches, nectarines (Prunus persica), and apricots, the outer fleshy part of the fruit (mesocarp) is consumed and the pit with the kernel frequently is discarded.
Can you eat raw apricot seeds?
Apricot kernels and the seeds of apples and pears contain a naturally occurring toxin (amygdalin). When eaten, this toxin can react with stomach enzymes and release a poison (cyanide) in the gut. This can cause stomach ache, illness, and can be fatal, especially for children.
Do watermelon seeds contain amygdalin?
Amygdalin content (56.45 mg/g) of watermelon juice (pulp and seeds) was lower than that of raw watermelon seeds (65.09 mg/g).
How do you extract cyanide from apricot seeds?
Amygdalin is extracted from almonds or apricot kernels by boiling in ethanol; on evaporation of the solution and the addition of diethyl ether, amygdalin is precipitated as white minute crystals.
What poison is made from peach pits?
Peach pits, which are hidden inside the nut-like husk, contain amygdalin, a substance that can degrade into hydrogen cyanide in the stomach.
