Enkola esinga okuba ey’obuyinza ey’okugezesa obuwoowo bwa chili peppers .

Mu 1912, omuwendo gwa Scoville Heat Units (SHU) gwaleetebwa okugera obungi bw’obuwoowo bw’entungo za chili. Ebisingawo ku nkola y’okupima entongole, laba tweet esoose.

Okukebera shu spiciness okuyita mu buwoomi bw’omuntu mu Buton .de kukwata ku nsonga era tekuliimu butuufu. N’olwekyo, mu 1985, ekibiina ky’abasuubuzi b’eby’akawoowo ekya American Spice Trade Association kyatwala enkola ya high-performance liquid chromatography (HPLC) okutumbula obutuufu bw’okupima obuwoowo bw’entungo za chili. Ekitundu ky’obuwoowo, ekimanyiddwa nga PPMH, kitegeeza ebitundu ku buli bukadde bw’ebbugumu ku buli bukadde obw’akawoowo.

HPLC, enfunyiro ya high-performance liquid chromatography, erimu okwawula n’okwekenneenya ebirungo mu mutabula gw’amazzi.

Okunoonyereza kulaga nti chili peppers zifuna spiciness yazo okuva mu bika musanvu eby’enjawulo ebya capsaicin, nga capsaicin ne dihydrocapsaicin bye bisookerwako. Enkola ya HPLC egaba ebipimo byokka ebiri mu capsaicinoids zino ebbiri. Ebala omugatte ogupimiddwa ogw’ebitundu byabwe, nga gugabanyizibwamu omuwendo gw’ekitundu ky’ekirungo ekipima (standard reagent) okuggya omuwendo mu PPMH.

Ekifaananyi ekirabika ekiwerekera kifaananyi kya kifaananyi ekikolebwa ekintu. Ekisiki ekiwanvu (horizontal axis) kikiikirira ekiseera ky’okusigala mu methanol, nga kigezesebwa okumala eddakiika 7. Ekisiki ekyesimbye kiraga amaanyi g’ensengekera agapimiddwa.

Munda mu kifaananyi .:

- 'A' kitegeeza ekitundu eky'oku ntikko ekya langi.

- 'B’ ekiikirira ekitundu ky’entikko ya capsaicin, ekizingiddwa ekikoona n’omusingi (ogulagibwa layini eriko ennukuta).

- 'C’ kitegeeza ekitundu eky’oku ntikko ekya Dihydrocapsaicin, ekizingiddwa ekikoona n’omusingi (ekirambikiddwa layini eriko ennukuta).

Okusobola okuzuula omutindo, ekitundu ky’entikko kirina okufunibwa n’okupimibwa nga tukozesa ebirungo ebikola (standard reagents). Omuwendo gwa PPMH ogubaliriddwa olwo gukubisibwamu 15 okufuna SHU spiciness ekwatagana. Enkola eno enzijuvu ekakasa okwekenneenya okutuufu era okw’omutindo okw’obuwoowo bwa chili pepper.
