Tsav los ntawm cov kev lag luam hauv nqes hav zoov xws li pab tsaug zog, pab daws kev nyuaj siab thiab lwm yam khoom, thiab cov kev thov loj heev uas tsim los ntawm kev mob kis, L-theanine yuav nrov nyob rau xyoo 2021. Tam sim no cia' s rov nkag siab L-theanine.
Nyhuv
L-theanine hmoov yog yam ntxwv tsis muaj protein ntau amino acid hauv tshuaj yej. Txij li nws raug rho tawm thiab txheeb xyuas, muaj kev tshawb nrhiav thoob ntiaj teb tsis txaus ntseeg txog nws daim ntawv thov hauv cov chaw tshuaj thiab kev noj qab haus huv. Qee qhov kev tshawb fawb pom tau tias nws muaj kev tiv thaiv oxidation, los tiv thaiv kev laus, thiab ntxiv dag zog. Kev ua haujlwm ntawm lub cev ua haujlwm xws li kev tiv thaiv kab mob, so ntawm lub siab tshee, tiv thaiv kev qaug zog thiab txo cov ntshav siab.
Lub cev thiab tshuaj
High-purity L-theanine yog cov hmoov dawb dawb lossis tawm-dawb, yooj yim soluble hauv dej, thiab cov kua aqueous yog me ntsis acidic, nrog caramel aroma thiab MSG tsw, insoluble hauv ethanol thiab ether.
Cov xwm txheej ntau lawm
Cov kev tsim tawm ntawm L-theanine suav nrog kev tsim tawm ntuj, tshuaj lom neeg ua kom zoo nkauj, biosynthesis thiab cog cov kab lis kev cai ntawm tes. L-theanine hmoov npaj los ntawm cov txheej txheem rho tawm tsuas yog li 1% rau 2% ntawm cov tshuaj yej qhuav, thiab cov nqi rho tawm yog qhov siab heev. Kev siv tshuaj lom neeg yog qhov qauv zoo dua, uas tuaj yeem tsim cov pheej yig L-theanine ntawm lub ntau ntau. Xyoo tsis ntev los no, cov tshuab hluav taws xob enzymatic synthesion L-theanine tau tsim kho sai heev, thiab microbial fermentation tau dhau los ua ib qho qauv tseem ceeb rau kev tsim cov theanine.
Kev Lag Luam Thoob Ntiaj Teb
Xyoo 2018, lub lag luam thoob ntiaj teb L-theanine tsim lag luam yog 725.09 tons, suav rau 42.96 lab las. Tuam Tshoj yog tus tau txais kev lag luam ntau tshaj plaws hauv ntiaj teb ntawm L-theanine nyob rau ob peb lub xyoo dhau los, uas kwv yees li 43.31% ntawm lub ntiaj teb kev lag luam hauv 2018, tom qab ntawd yog North America. Txog 22.98%. Tuam Tshoj tseem yog tus xa khoom loj tshaj plaws, nrog ntau lawm kev lag luam kwv yees li 75% xyoo 2018.
Xyoo 2018, kev noj haus ntawm theanine hauv cov zaub mov thiab dej haus yog 483.93 tons, suav txog 66.74% ntawm kev siv theanine, kev siv cov khoom kho mob yog 195.85 tons, thiab kev lag luam ntawm kev lag luam tshuaj yog 64.94 tons.
Daim ntawv thov khoom ntawm theanine
L-theanine hmoov yog siv ntxiv rau hauv kev siv ntau yam, xws li zaub mov thiab dej haus kev lag luam, cov khoom lag luam kev noj qab haus huv uas txo kev qaug zog, txhim kho kev kawm thiab cim xeeb, thiab tshuaj (xws li tshuaj anticancer thiab tshuaj antihypertensive). Qee qhov chaw tsim tshuaj paus' chocolate muaj theanine, uas yog siv los maj mam hloov cov cawv thiab cov dej cawv. Tam sim no, tsuas yog tshuaj yej theanine (20% cov ntsiab lus) tuaj yeem muab ntxiv rau cov zaub mov hauv khw.
