Hanyar mafi iko don gwada kayan yaji na barkono barkono

A cikin 1912, an gabatar da ma'anar Scoville Heat Units (SHU) don ƙididdige yawan barkono barkono. Don cikakkun bayanai kan takamaiman hanyar aunawa, da fatan za a duba tweet ɗin da ya gabata.

Kima na SHU yaji ta wurin ɗanɗanon ɗan adam yana da ƙayyadaddun ra'ayi kuma ba shi da daidaito. Sakamakon haka, a cikin 1985, Ƙungiyar Kasuwancin Kayan Yaƙi ta Amurka ta karɓi Hanyar Liquid Chromatography (HPLC) Mai Girma don haɓaka daidaiton ma'aunin barkono barkono. Nau'in yaji, wanda aka sani da ppmH, yana nuna sassan kowane miliyan na zafi akan kowane miliyon.

HPLC, acronym don babban aiki na chromatography na ruwa, ya ƙunshi rabuwa da bincike na mahadi a cikin cakuda ruwa.

Bincike ya nuna cewa barkono barkono suna samun yaji daga nau'ikan capsaicin guda bakwai, tare da capsaicin da dihydrocapsaicin sune na farko. Hanyar HPLC tana auna abubuwan da ke cikin waɗannan capsaicinoids guda biyu. Yana ƙididdige jimlar ma'auni na yankunansu, yana raba shi da ƙimar yanki na daidaitaccen reagent don samun ƙima a ppmH.

Hoton gani mai rakiyar zane zane ne wanda kayan aikin ya samar. Axis a kwance yana wakiltar lokacin riƙewa a cikin methanol, tare da tsawon gwaji na mintuna 7. Axis a tsaye yana kwatanta ƙarfin da aka auna.

A cikin zane:

- 'a' yana nuna iyakar wurin launi.

- 'b' yana wakiltar kololuwar yanki na capsaicin, wanda ke kewaye da lanƙwasa da tushe (wanda aka nuna ta layin dige-dige).

- 'c' yana nuna kololuwar yanki na dihydrocapsaicin, wanda ke kewaye da lanƙwasa da tushe (wanda aka zayyana ta layin dige-dige).

Don tabbatar da daidaito, dole ne a samu yankin kololuwa kuma a auna shi ta amfani da madaidaitan reagents. Ƙimar ppmH da aka ƙididdige sannan ana ninka ta 15 don samun daidaitaccen yaji na SHU. Wannan ingantacciyar hanya tana tabbatar da daidaito da daidaiton ƙimar barkono barkono.

Na gaba:

Hukuncin ingancin barkono: spiciness, launi, oiliness, abinci mai gina jiki, yawan amfanin ƙasa
