Kev ua ntawmtshuaj yej ntsuabNws tsuas yog muab faib ua peb kauj ruam: fixation, dov thiab ziab, qhov tseem ceeb ntawm uas yog fixation.Cov nplooj tshiab yog inactivated thiab cov enzyme kev ua si yog inactivated.Ntau yam tshuaj lom neeg muaj nyob rau hauv no yog qhov tseem ceeb ntawm lub cev thiab tshuaj hloov pauv nyob rau hauv qhov xwm txheej tsis muaj enzyme cuam tshuam los ntawm kev ua ntawm tshav kub, yog li tsim cov yam ntxwv zoo ntawm cov tshuaj yej ntsuab.

Fixation plays lub luag haujlwm txiav txim siab hauv qhov zoo ntawm cov tshuaj yej ntsuab.Los ntawm qhov kub thiab txias, cov khoom ntawm cov enzymes nyob rau hauv cov nplooj tshiab raug rhuav tshem, thiab oxidation ntawm polyphenols tiv thaiv kom tsis txhob muaj cov nplooj reddening;Nyob rau tib lub sij hawm, ib feem ntawm cov dej nyob rau hauv nplooj yog evaporated, ua rau cov nplooj mos, tsim tej yam kev mob rau dov thiab shaping.Nrog cov evaporation ntawm cov dej, cov tshuaj tsw qab uas muaj ntxhiab tsw nrog cov nyom aroma hauv cov nplooj tshiab volatilize thiab ploj mus, yog li txhim kho aroma ntawm tshuaj yej.

Tsuas yog cov tshuaj yej tshwj xeeb, cov txheej txheem no yog tag nrho ua tiav hauv lub tshuab fixation.Cov yam ntxwv uas cuam tshuam rau qhov zoo ntawm fixation muaj xws li fixation kub, tus nqi ntawm cov nplooj, hom fixation tshuab, lub sij hawm, thiab fixation txoj kev.Lawv yog tag nrho thiab muaj kev cuam tshuam thiab txwv.

Kev cuam tshuam los ntawm ntau yam tshuaj yej, cov txheej txheem ntawm fixation kuj txawv, nrog raukib fixation, sun-dried fixation, thiab steamed fixation.
