ʻO ke ala mana loa no ka hoʻāʻo ʻana i ka ʻono o nā pepa chili
Jan. 13, 2026
I ka makahiki 1912, ua hoʻokomo ʻia ka helu helu Scoville Heat Units (SHU) no ka helu ʻana i ka ʻono o ka pepa chili. No nā kikoʻī e pili ana i ke ʻano ana kikoʻī, e ʻoluʻolu e nānā i ka tweet ma mua.
ʻO ka loiloi ʻana i ka ʻono SHU ma o ka ʻono kanaka he kumu maoli a nele i ka pololei. No laila, i ka makahiki 1985, ua hoʻohana ka American Spice Trade Association i ke ʻano High-Performance Liquid Chromatography (HPLC) e hoʻonui i ka pololei o ke ana ʻana i ka ʻala ʻala. ʻO ka ʻāpana o ka spiciness, i kapa ʻia ʻo ppmH, e hōʻike ana i nā ʻāpana o ka miliona o ka Heat per million spiciness.
ʻO HPLC, kahi acronym no ka chromatography wai hana kiʻekiʻe, pili i ka hoʻokaʻawale ʻana a me ka nānā ʻana o nā pūhui i loko o kahi hui wai.
Hōʻike nā haʻawina e loaʻa i nā pepa chili ko lākou ʻono mai nā ʻano capsaicin ʻokoʻa ʻehiku, me ka capsaicin a me ka dihydrocapsaicin ka mea mua. ʻO ke ala HPLC wale nō e ana i ka ʻike o kēia mau capsaicinoids ʻelua. Heluhelu ia i ka huina kaumaha o ko lakou mau wahi, e puunaue ana ia me ka waiwai o ka reagent ma'amau e loaa ai ka waiwai ma ppmH.
ʻO ke kiʻi kiʻi kiʻi i hana ʻia e ka mea kani. Hōʻike ka axis horizontal i ka manawa paʻa i ka methanol, me ka lōʻihi o ka hoʻāʻo ʻana he 7 mau minuke. Hōʻike ka axis vertical i ka ikaika o ka hopena i ana ʻia.
Iloko o ke kii:
- ''o ia ka 'āpana piko o ke kala.
- 'b' hōʻike i ka ʻāpana kiʻekiʻe o ka capsaicin, i hoʻopaʻa ʻia e ka pihi a me ka laina kumu (i hōʻike ʻia e ka laina kiko).
- 'c' 'o ia ka 'āpana ki'eki'e o ka dihydrocapsaicin, i ho'opa'a 'ia e ka pihi a me ka palena (i wehewehe 'ia e ka laina kiko).
No ka ʻike ʻana i ka standardization, pono e kiʻi ʻia ka wahi kiʻekiʻe a ana ʻia me ka hoʻohana ʻana i nā reagents maʻamau. Hoʻonui ʻia ka waiwai ppmH i helu ʻia me ka 15 e loaʻa ai ka ʻono SHU pili. Hāʻawi kēia ʻano kikoʻī i ka loiloi kikoʻī a maʻamau o ka ʻono o ka pepa chili.
