Amino acids zvakakosha zvinonhuhwirira mutii. Panguva yekugadzirisamichina yekugadzira tii, akasiyana enzymatic kana asiri-enzymatic maitiro achaitika zvakare uye anoshandurwa kuita zvakakosha zvikamu zvekunhuhwirira kwetii uye pigment. Parizvino, makumi maviri nematanhatu amino acids akawanikwa mutii, kusanganisira makumi maviri eprotein-yakatorwa amino acids uye 6 isina-protein-inotorwa amino acids.

1. Mhedzisiro yetii germplasm zviwanikwa pane synthesis, metabolism uye shanduko yetii amino acids.

Zvirimo zveamino acids, kunyanya theanine, zvinosiyana pakati pemhando dzakasiyana dzemuti wetii. Huwandu hwemhando dzemashizha egirinhi hunowedzera nechimiro cheshizha rimwe chete, mashizha maviri, uye mashizha matatu, uye zvirimo mu theanine mumabukira madiki ndizvo zvakanyanya.

2. Kufurira kwenzvimbo yekugadzira pane synthesis, metabolism uye shanduko yetii amino acids

Muchirimo, unogona kushandisa akukohwa kwetiir kukurumidza kutora mashizha etii. Iyo amino acid yemukati yechirimo tii yakanyanya kukwirira kupfuura iyo yezhizha tii. Chikonzero ndechekuti chiedza chakasimba uye tembiricha yakakwira muzhizha inozotungamira kune yakaderera muti wetii nitrogen metabolism uye yakasimba theanine hydrolysis uye kushandura kugona, zvichikonzera kuderera kweamino acid kugutsikana mumapfungi madiki muzhizha.

3. Mhedzisiro yekugadzira tekinoroji uye kuchengetedza pane synthesis, metabolism uye shanduko yetii amino acids.

Shanduko mune amino acid yemukati yetii panguva yekugadziriswa inonyanya kukanganiswa nezvinhu zviviri. Kune rimwe divi, mamwe madiki mapuroteni mapuroteni kana polypeptides anopinda munharaunda hydrolysis uye pyrolysis pasi pechiito chekunyorova uye kupisa, zvichikonzera kuunganidzwa kweamino acids; kune rumwe rutivi, iyo amino acids ndiyo Inoderedzwa kuburikidza neoxidation, hydrolysis, shanduko, uye kusanganiswa neshuga uye polyphenols kuumba ruvara, kunhuhwirira uye kuravira zvinhu.

(1) Kupararira nekusvava

Panguva yekuparadzira uyemuchina wekuomesa tiinhanho, emahara amino acids anoumbwa neprotein hydrolysis, saka iyo yakazara amino acid yemukati inowanzoratidza maitiro ekukwira. Nekudaro, iyo theanine yemukati inomutsa kutaura kwe theanine hydrolase nekuda kwekurasikirwa nemvura, zvichiita kuti theanine iite hydrolyzed, ichiratidza Downtrend.

(2) Danho rekuvirisa

Kuvirisa kunonyanya kukamurwa kuita polyphenol oxidase kuvirisa uye microbial kuvirisa. Munguva yekuvirisa kwetii, maseru anokuvadzwa mushure mekupfuura nemutea rolling machine, uye zvinhu zve phenolic zviri mumaseru zvinoiswa oxidized ne polyphenol oxidase. Iyo quinone inokonzeresa makomisheni inodzokororwa kana isingadzokekekemikari inodzokororwa nemaamino acids, ine imwe mhedzisiro pakunhuhwirira kweblack tii. basa rinokosha.

(3) Kugadzirisa uye kuomesa

Munguva yekugadzirisa uye kuomesa matanho, kupisa kwepamusoro kunoita basa guru. Amino acids anowanzo sangana neoxidative polymerization neo-quinones kana kusangana neMaillard maitiro ane carbonyl makomisheni. Iyo yakakwirira tembiricha yemuchina wekugadzirisa tii, inokwira tembiricha yetea fixing machine, iyo yakanyanya hydrolyzed iyo amino acids ichave ichisimudzira iyo hydrolysis yemapuroteni. uye kushandurwa.

(4)Kuchengeta

Munguva yekuchengetera tii, amino acids anozowedzera kuderedzwa uye nekushandurwa nekuda kwekuchinja kwezvakatipoteredza uye nguva. Iyo yakakwirira tembiricha uye kuwedzera kwehunyoro, kunowedzera kuwanda kwekuora.
