Ma amino acid ndi zinthu zokometsera mu tiyi. Pa processing wamakina opangira tiyi, machitidwe osiyanasiyana a enzymatic kapena osakhala enzymatic adzachitikanso ndikusinthidwa kukhala zigawo zofunika za fungo la tiyi ndi utoto. Pakali pano, ma amino acid 26 apezeka mu tiyi, kuphatikiza ma amino acid 20 opangidwa ndi mapuloteni ndi 6 amino acid omwe sanatengeke ndi mapuloteni.

1. Zotsatira za tiyi germplasm resources pa kaphatikizidwe, kagayidwe kachakudya ndi kusintha kwa tiyi amino zidulo.

Zomwe zili mu amino acid, makamaka theanine, zimasiyana pakati pa mitundu yosiyanasiyana ya tiyi. Kuchuluka kwa mitundu ya masamba obiriwira kumawonjezeka ndi malo a tsamba limodzi, masamba awiri, ndi masamba atatu, ndipo zomwe zili mu theanine mu mphukira zazing'ono ndizopamwamba kwambiri.

2. Chikoka cha chilengedwe chopanga pa kaphatikizidwe, kagayidwe kake ndi kusintha kwa tiyi amino acid

M'chaka, mungagwiritse ntchito akukolola tiyir kuti asankhe masamba a tiyi mwachangu. Ma amino acid omwe ali mu tiyi ya masika ndiwokwera kwambiri kuposa tiyi yachilimwe. Chifukwa chake ndi chakuti kuwala kwamphamvu ndi kutentha kwakukulu m'chilimwe kudzachititsa kuti tiyi ikhale yotsika mtengo wa nayitrogeni kagayidwe kachakudya ndi mphamvu ya theanine hydrolysis ndi kusintha kwamphamvu, zomwe zimapangitsa kuti amino acid achepetse mphukira zazing'ono m'chilimwe.

3. Zotsatira zaukadaulo waukadaulo ndi kusungirako pa kaphatikizidwe, kagayidwe kazakudya ndikusintha kwa tiyi amino acid.

Kusintha kwa amino acid mu tiyi panthawi yokonza kumakhudzidwa makamaka ndi mbali ziwiri. Kumbali imodzi, mapuloteni ena ang'onoang'ono a molekyulu kapena ma polypeptides amakumana ndi hydrolysis ndi pyrolysis m'malo mwa chinyezi ndi kutentha, zomwe zimapangitsa kuti ma amino acid achuluke; Komano, amino zidulo ndi Iwo yafupika kudzera makutidwe ndi okosijeni, hydrolysis, kusintha, ndi kuphatikiza ndi shuga ndi polyphenols kupanga mtundu, fungo ndi kukoma zinthu.

(1) Kufalikira ndi kufota

Pa kufalikira ndimakina ochapira tiyiMagawo, ma amino acid aulere amapangidwa ndi mapuloteni a hydrolysis, kotero kuchuluka kwa amino acid nthawi zambiri kumawonetsa kukwezeka. Komabe, zomwe zili mu theanine zimayambitsa mawu a theanine hydrolase chifukwa cha kutaya madzi, kuchititsa theanine kukhala hydrolyzed, kusonyeza Downtrend.

(2) Gawo la kuwira

Nayonso mphamvu makamaka anawagawa polyphenol oxidase nayonso mphamvu ndi tizilombo ting'onoting'ono nayonso mphamvu. Panthawi nayonso mphamvu ya tiyi, maselo amawonongeka pambuyo podutsamakina opukutira tiyi, ndipo zinthu za phenolic m'maselo zimakokedwa ndi polyphenol oxidase. Zotsatira zake za quinone zimakhala ndi zinthu zina zosinthika kapena zosasinthika ndi ma amino acid, zomwe zimakhudza kununkhira kwa tiyi wakuda. udindo wofunikira.

(3) Kukonza ndi kuyanika

Panthawi yokonza ndi kuyanika, kutentha kwakukulu kumagwira ntchito yaikulu. Ma amino acid nthawi zambiri amakhala ndi oxidative polymerization ndi o-quinones kapena amakumana ndi Maillard ndi mankhwala a carbonyl. The apamwamba kutentha kwa tiyi kukonza makina, ndi apamwamba kutentha kwamakina okonzera tiyi, ndi hydrolyzed kwambiri amino zidulo adzakhala pamene kulimbikitsa hydrolysis wa mapuloteni. ndi kusintha.

(4)Kusungirako

Panthawi yosungiramo tiyi, ma amino acid adzawonongekanso ndikusinthidwa chifukwa cha kusintha kwa chilengedwe ndi nthawi. Kutentha kwapamwamba komanso chinyezi chachikulu, kumapangitsanso kuwonongeka kwakukulu.
