Thaum tham txog tshuaj yej, peb feem ntau tham txog tag nrho fermentation, semi-fermentation, thiab lub teeb fermentation. Covtshuab fermentationyog ib lub tshuab siv feem ntau siv hauv cov txheej txheem tshuaj yej fermentation. Cia peb kawm txog fermentation ntawm tshuaj yej.

Fermentation ntawm tshuaj yej - lom oxidation

Suav tshuaj yej tau muab faib ua rau 6 pawg tshuaj yej loj raws li qib sib txawv ntawm fermentation thiab kev ua tiav ntau lawm. Hauv tshuaj yej, tib nplooj ntsuab tau ua tiav rau hauv cov tshuaj yej ntsuab, tshuaj yej dub, tshuaj yej oolong, thiab lwm yam los ntawm kev tswj cov roj ntsha oxidation, cov txheej txheem uas tseem hu ua fermentation tsis raug. Cov txheej txheem no ntau dua li cov tshuaj tiv thaiv enzymatic, thiab tej zaum yuav tsum tau hu ua lom oxidation. Nrog kev pab los ntawm lom oxidation ntawm tshuaj yej cell phab ntsa puas nyob rau hauv lubtshuaj yej fermentation tshuab, cov oxidases tam sim no nyob rau hauv lub cell phab ntsa txhawb ib tug series ntawm oxidation txheej txheem ntawm catechins.

Hauv cov tshuaj yej cell, catechins muaj nyob rau hauv cov kua cell, thaum oxidase feem ntau muaj nyob rau hauv lub cell phab ntsa, tsis tsuas yog nyob rau hauv cov kab mob, yog li ntawd lub cell phab ntsa yuav tsum tau puas. Qhov no ib txwm piav qhia yog vim li cas fermented tshuaj yej yuav tsum dov nrog atshuaj yej nplooj roller. Raws li qhov sib txawv ntawm oxidation ntawm polyphenols, nws tuaj yeem muab faib ua tag nrho fermentation, semi-fermentation thiab lub teeb fermentation. Hauv cov tshuaj yej dub, qib ntawm oxidation ntawm polyphenols yog siab heev, uas yog hu ua tag nrho fermentation; Hauv oolong tshuaj yej, qib ntawm oxidation ntawm polyphenols yog ib nrab, uas yog hu ua semi-fermentation.

Cov saum toj no yog lub ntsiab lus tseem ceeb ntawm fermentation feem ntau hais hauv Suav tshuaj yej. Txawm li cas los xij, vim muaj ntau yam tshuaj yej hauv Suav teb, cov txheej txheem ua haujlwm nplua nuj thiab kev npaj, thiab cov ntsiab lus sib txawv ntawm qhov zoo, tib neeg feem ntau siv.hluav taws xob tshuaj yej fermentation ua tshuabua kom tswj tau fermentation. Hauv kev tsim thiab tsim cov txheej txheem zoo ntawm qee cov tshuaj yej nplooj, ntxiv rau qhov saum toj no-hais fermentation nyob rau hauv kev nkag siab ntawm lom oxidation ntxiv rau nws tus kheej cov tshuaj tiv thaiv enzymatic, cov kab mob kuj tseem yuav koom nrog qee qhov txuas.
