Eyona ndlela igunyazisiweyo yokuvavanya ubunongo bepepile



Ngomnyaka we-1912, i-index ye-Scoville Heat Units (SHU) yaziswa ukulinganisa i-spiciness ye-pepper ye-chili. Ngeenkcukacha malunga nendlela ethile yokulinganisa, nceda ujonge kwi-tweet eyandulelayo.

 

Uvavanyo lwe-SHU spiciness ngencasa yomntu ixhomekeke ngokwendalo kwaye ayinakuchaneka. Ngenxa yoko, ngo-1985, i-American Spice Trade Association yamkela i-High-Performance Liquid Chromatography (HPLC) indlela yokuphucula ukuchaneka komlinganiselo wobunongo bechilipele. Iyunithi yobunongo, eyaziwa ngokuba yi-ppmH, ichaza iinxalenye kwisigidi soBubushushu kwisigidi sobulawu.

 

I-HPLC, i-acronym ye-high-performance liquid chromatography, ibandakanya ukwahlukana kunye nohlalutyo lweekhompawundi kumxube wolwelo.

 

Uphononongo lubonisa ukuba i-chili pepper ifumana ubuqholo kwiintlobo ezisixhenxe ezahlukeneyo ze-capsaicin, kunye ne-capsaicin kunye ne-dihydrocapsaicin zezona ziphambili. Indlela ye-HPLC ilinganisa kuphela umxholo wezi capsaicinoids zimbini. Ibala isixa esilinganisiweyo seendawo zabo, iyahlula ngexabiso lendawo ye-reagent standard ukuze ifumane ixabiso kwi-ppmH.

 

Ukumelwa okubonakalayo okukhaphayo ngumzobo wegraphical oveliswe sisixhobo. I-axis ethe tyaba imele ixesha lokugcinwa kwe-methanol, kunye novavanyo lwexesha lemizuzu ye-7. I-axis ethe nkqo ibonisa ubungakanani bokusabela okulinganisiweyo.

Ngaphakathi komzobo:

- 'a' ibonisa indawo encopho yombala.

- 'b' imele indawo ephezulu ye-capsaicin, evalelwe yigophe kunye nesiseko (esibonakaliswe ngumgca onamachaphaza).

- 'c' ibonisa indawo encopho ye-dihydrocapsaicin, evalelwe yigophe kunye nesiseko (icaciswe ngomgca ochokoziweyo).

 

Ukuqinisekisa ukulinganisa, indawo ephezulu kufuneka ifunyanwe kwaye ilinganiswe ngokusebenzisa ii-reagents eziqhelekileyo. Ixabiso le-ppmH elibaliweyo liphinda-phindwe nge-15 ukufumana i-SHU spiciness ehambelanayo. Le ndlela ibanzi iqinisekisa uvandlakanyo oluchanekileyo kunye nomgangatho wobunongo bechilipele.
