Why are my chili peppers so hot?
Chili pepper heat is borne in the membranes surrounding the seeds. If you get healthy fruit, they will have a full interior of the pithy hot membranes and a higher heat range. On the opposite side, you may have been too kind to your peppers.
What is the hottest part of a chilli?
The hottest part of a chilli is not the seeds, as many people think, but the white flesh that houses the seeds, known as the placenta. But why did chillies evolve to be hot in the first place?
Do chilies grow hotter after they are harvested?
If your plant is vigorous and well cared for, the fruits will burst with flavor and spicy heat. Once the pepper has been harvested, it’s not going to grow hotter. However, you can maximize flavor in several ways. Dried chilies preserve well and the heat is intensified when all the water has evaporated in the fruit.
What is the science behind chillies?
Humans have been cultivating chillies for 6000 years, but we are still learning new things about the science behind their heat and how it reacts with our body. In the late 1990s, scientists identified the pain nerves that detect capsaicin: the chemical in chillies responsible for most of the burn.

Why Are Peppers Hot?
An ingredient called Capsaicin is what gives peppers their fiery spice. It is odorless and tasteless except for the hot element. How little or how much of this substance each pepper creates within depends on different factors. These factors have long been the subject of much research.
What is Capsaicin?
Capsaicinoids are the chemical produced in fruits of the plant. It is an oil-like compound, repelling water and is primarily located in the membranes of the fruit, as well as more lightly in the flesh. It has been used for as long as 8000 years to flavor meats and vegetables and to help preserve food.

Chili Peppers Not Hot
You’ve heard the phrase, “Some like it hot.” They aren’t really referring to peppers, but the saying holds true anyway. The various levels of heat that develop in a pepper depend upon the amount of capsaicin.
Factors for Chili Peppers Not Getting Hot
Chilies require plenty of heat, water, and sunlight. In the absence of one of these conditions, the fruit will not fully mature. Mature peppers generally carry the most heat. In cooler climates, start the seeds indoors and plant them after all danger of frost and ambient temperatures range 65 degrees F. (18 C.).
How to Get Hot Chili Peppers
For chili peppers too mild, look first to the variety you are selecting. Taste a few kinds from the supermarket or in recipes to find out which level of heat you’re seeking. Then get starts and plant in a sunny, well-drained location where temperatures stay at least 80 degrees F. (27 C.) for most of the day.
