A red bell pepper supplies twice the vitamin C and eight times the vitamin A content of a green bell pepper. [12] The bell pepper is the only member of the genus Capsicum that does not produce capsaicin, a lipophilic chemical that can cause a strong burning sensation when it comes in contact with mucous membranes.
The most recognized Capsicum without capsaicin is the bell pepper, [43] a cultivar of Capsicum annuum, which has a zero rating on the Scoville scale. The lack of capsaicin in bell peppers is due to a recessive gene that eliminates capsaicin and, consequently, the hot taste usually associated with the rest of the genus Capsicum. [44]
Capsaicin synthesis in chilies places a strain on their water resources. [91] This directly affects their fitness, as it has been observed that standard concentration of capsaicin of peppers in high moisture environments in the seeds and pericarps of the peppers reduced the seeds production by 50%. [92]
Different peppers contain different concentrations of capsaicin, which is measured using the Scoville scale, Dr. Paul Terry, professor of epidemiology at the University of Tennessee Medical Center ...
By Esther Sung The word "pepper" refers to members of the genus Capsicum, which includes hot varieties, also known as chile peppers, and sweet varieties, such as the bell pepper. Up until the ...
Capsaicin is the component in peppers that makes them spicy. It's also an irritant, which is why you feel a burning sensation when you eat something spicy. Specifically, capsaicin binds to and ...
Another variant of Capsicum annuum, the bell pepper are quite different from Chiltepin peppers, being described as "sweet" as they do not contain high concentrations of capsaicin and are rated a 0 on the Scoville heat scale. [15] Bell peppers grow on shrub body plants, and the fruits are large, quadrangular, and fleshy.
For law-enforcement-grade pepper spray, values from 500,000 up to 5 million SHU have been reported, [1] [13] but the actual strength of the spray depends on the dilution. [3] This problem can be overcome by stating the water content along with the Scoville value. One way to do so is the "D-value", defined as total mass divided by dry mass. [14]
