Acide Amino ni ibintu byingenzi bihumura icyayi. Mugihe cyo gutunganyaimashini zitunganya icyayi, reaction zitandukanye zidasanzwe cyangwa zidafite imisemburo nazo zizabaho kandi zihindurwe mubice byingenzi bigize impumuro yicyayi na pigment. Kugeza ubu, aside amine 26 yabonetse mu cyayi, harimo aside amine 20 ikomoka kuri poroteyine na aside 6 ikomoka kuri poroteyine.

1. Ingaruka zumutungo wa germplasm yicyayi kuri synthesis, metabolism no guhindura icyayi amino acide

Ibigize aside amine, cyane cyane theanine, biratandukanye muburyo butandukanye bwibiti byicyayi. Ubwinshi bwubwoko bwamababi yicyatsi bwiyongera hamwe nibibabi byikibabi kimwe, amababi abiri, namababi atatu, kandi ibiri muri theanine mumashami akiri muto ni byinshi.

2. Ingaruka yibidukikije bitanga umusaruro kuri synthesis, metabolism no guhindura icyayi amino acide

Mu mpeshyi, urashobora gukoresha aicyayir guhitamo vuba amababi yicyayi. Aminide acide yicyayi yimpeshyi irarenze cyane icyayi cyizuba. Impamvu nuko urumuri rukomeye nubushyuhe bwinshi mugihe cyizuba bizatuma igiti cyicyayi cya azote metabolism igabanuka hamwe na hydrolysis ikomeye ya theanine hamwe nubushobozi bwo guhindura, bikavamo aside aside amine muke mumashami akiri mato.

3. Ingaruka zikoranabuhanga ryo gutunganya no kubika kuri synthesis, metabolism no guhindura icyayi amino acide

Imihindagurikire ya aside amine yicyayi mugihe cyo kuyitunganya yibasiwe cyane nibintu bibiri. Ku ruhande rumwe, poroteyine ntoya cyangwa polypeptide zimwe na zimwe ziterwa na hydrolysis na pyrolysis zaho bitewe nubushyuhe nubushyuhe, bigatuma habaho aside aside amine; kurundi ruhande, aside amine iragabanuka binyuze muri okiside, hydrolysis, guhinduka, hamwe no guhuza isukari na polifenole kugirango bibe ibara, impumuro nziza nuburyohe.

(1) Gukwirakwira no gukama

Mugihe cyo gukwirakwiza noimashini yumisha icyayiibyiciro, aside amine yubusa ikorwa na protein hydrolysis, bityo rero aside amine yose hamwe muri rusange yerekana inzira yo kuzamuka. Nyamara, ibirimo bya theanine bigira uruhare mu kwerekana hydrolase ya ananine kubera gutakaza amazi, bigatuma theanine iba hydrolyz, byerekana Downtrend.

(2) Icyiciro cya fermentation

Fermentation igabanijwemo cyane cyane polifenol oxydease fermentation na fermentation ya mikorobe. Mugihe cyo gusembura icyayi, selile zangiritse nyuma yo kunyuzwa muriimashini izunguruka icyayi, hamwe nibintu bya fenolike mu ngirabuzimafatizo bigizwe na okiside ya polifenol. Ibivamo bya quinone bivamo ibintu bimwe na bimwe bidasubirwaho cyangwa bidasubirwaho imiti ya aside amine, bigira ingaruka runaka kumpumuro yicyayi cyirabura. uruhare rukomeye.

(3) Gukosora no gukama

Mugihe cyo gutunganya no gukama, ubushyuhe bwo hejuru bugira uruhare runini. Aminide acide ikunze gukorerwa polymerisiyumu hamwe na o-quinone cyangwa ikagira Maillard reaction hamwe na karubone. Ubushyuhe bwo hejuru bwimashini itunganya icyayi, nubushyuhe bwaimashini itunganya icyayi, hydrolyzed nyinshi aside amine izaba mugihe iteza hydrolysis ya proteyine. no guhinduka.

(4) Ububiko

Mugihe cyo kubika icyayi, aside amine izarushaho kwangirika no guhinduka kubera ihinduka ryibidukikije nigihe. Ubushyuhe buri hejuru nubushuhe bwinshi, niko kwangirika kwinshi.
