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).
How do you extract cyanide from apricot seeds?

What poison is in apricot kernels?

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 fruit 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 many would you have to eat to get sick?
How do I get rid of amygdalin?
In this report, three methods for the extraction of amygdalin from the medicinal materials are compared: ultrasonic extraction by methanol, Soxhlet extraction by methanol, and reflux extraction by water. The results show that reflux extraction water containing 0.1% citric acid is the best option.
Are apricot seeds safe to eat?
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.
