Where is the most heat in hot peppers?

Answer 1

Many people believe that the seeds make a pepper hot, but actually they contain little to no capsaicin (the compound that makes the Chile "hot"). The poor seeds are getting a bum rap. It is guilt by association...the seeds are attached inside a chile to the membrane that is the hottest part of a chile and that is how they get the capsaicin-containing oils from that membrane on them which then seems to be the source. The membranes that hold the seeds inside the chiles are the hottest parts with the most capsaicin.

Capsaicin binds to receptors in the mouth that send signals to the brain that tell it that the tissue is "burning", however, it is just trickery and a sensation of the burn, there is not any actual tissue damage from capsaicin in capsicum (peppers/chiles).

You will note that the stem end, where much of the capsaicin-containing membrane is concentrated and attached to the fruit, is much hotter than the tip of any chile for this reason. So, if you want to judge how hot a certain pepper is, take the sample from the middle of the fruit.

Answer 2

The inner wall of the pepper is the hottest. It is a common misconception that the seeds are the hottest. They only contain a small amount of capsaicin, the chemical that makes peppers spicy.

Answer 3

the hottest part of a chilli is actually the white membrane inside that the seeds are attached to.. not the actual seeds.
