Aug 12 : A team of researchers at Baylor University in Texas have developed a mathematical computer model to measure the “heat” inside a chilli pepper.

Peppers get their hotness from a family of chemicals called capsaicinoids, with two members of the group (capsaicin and dihydrocapsaicin) making up 90 percent of the capsaicinoids. The spiciness of each pepper depends on the relative amounts of these hot compounds hidden inside the pepper’s flesh.

“Capsaicinoids are the active ingredient in pepper spray, tear gas and some arthritis medications, not to mention spices and foods like salsa, so a wide range of industries could find this new approach useful,” said lead scientist Kenneth Busch, a chemist at Baylor University in Texas.

Currently, the standard test of pepper hotness relies on a process called high-performance liquid chromatography, which is expensive as well as time consuming (each sample can take 10 minutes to run).

The machine chemically separates all the different compounds before spitting out a reading.

Now Busch and his colleagues have developed a computer model that can calculate the hotness of a pepper based on information gleaned from spectroscopy, which measures how a substance absorbs light.

The program is set up so that when a scientist feeds a “spectra” into it, the program disregards components uninvolved in spicy heat and focuses only on the capsaicinoid factors.

The scientists say the process could provide quicker and cheaper information to certain food and drug industries.

For instance, some arthritis medications contain chemicals from hot peppers, said Busch.

The findings are scheduled for publication in an upcoming issue of the Journal of Agricultural and Food Chemistry, reports LiveScience. (ANI)
