Ko te tikanga tino whai mana mo te whakamatautau i te raukikini o nga pepa tiihi



I te tau 1912, i whakauruhia te tohu Scoville Heat Units (SHU) ki te tatau i te raukikini o nga pepa tiihi. Mo nga korero mo te tikanga inenga motuhake, tirohia te tweet o mua.

 

Ko te aromatawai i te raukikini o te SHU na roto i te reka o te tangata, he mea hangai, he kore tika. No reira, i te tau 1985, ka whakamahia e te American Spice Trade Association te tikanga High-Performance Liquid Chromatography (HPLC) hei whakarei ake i te tika o te inenga mo te raukikini pepa tiihi. Ko te waeine o te raukikini, e kiia nei ko te ppmH, e tohu ana i nga wahanga mo te miriona o te wera mo te miriona raukikini.

 

Ko te HPLC, he acronym mo te chromatography wai mahi teitei, ko te wehenga me te tātaritanga o nga pūhui i roto i te ranunga wai.

 

Ko nga rangahau e whakaatu ana ko nga pepa tiihi ka ahu mai i te raukikini mai i nga momo capsaicin motuhake e whitu, ko te capsaicin me te dihydrocapsaicin te mea tuatahi. Ko te tikanga HPLC anake te ine i nga ihirangi o enei capsaicinoids e rua. Ka tatauhia e ia te tapeke taumahatanga o o raatau waahi, ka wehewehea ki te uara horahanga o te reagent paerewa kia puta he uara ki te ppmH.

 

Ko te whakaaturanga ataata e whai ake nei he hoahoa kauwhata i hangaia e te taputapu. Ko te tuaka whakapae e tohu ana i te wa pupuri i te methanol, me te roanga whakamatautau mo te 7 meneti. Ko te tuaka poutū e whakaatu ana i te kaha tauhohenga ine.

I roto i te hoahoa:

- Ko te 'a' he tohu i te waahi teitei o te tae.

- Ko te 'b' e tohu ana i te waahi teitei o te capsaicin, e kopakia ana e te anau me te raina turanga (kua tohuhia e te raina iraira).

- Ko te 'c' e tohu ana i te waahi teitei o te dihydrocapsaicin, e mau ana i te anau me te raina turanga (kua tohua e te raina iraira).

 

Hei whakatau i te paerewa, me whiwhi te waahi tihi me te ine ma te whakamahi i nga reagents paerewa. Ka whakareatia te uara ppmH kua tatau ki te 15 kia whiwhi ai i te raukikini SHU. Ma tenei huarahi matawhānui e whakarite kia tika ake te arotakenga o te raukikini pepa tiihi.
