Ua ib yam khoom noj uas yuav tsum muaj hauv chav ua noj, tus nqi ntawm cov kua ntses taum pauv txawv heev. Nws muaj txij li ob peb yuan mus txog ntau pua yuan. Dab tsi yog cov laj thawj tom qab nws? Qhov zoo ntawm cov khoom siv raw, cov txheej txheem tsim khoom, cov amino acid nitrogen thiab cov hom additives ua ke yog cov lej tseem ceeb ntawm cov khoom noj no.
1. Kev sib ntaus sib tua ntawm cov khoom siv raw: kev sib tw ntawm cov organic thiab cov tsis yog organic
Muaj nqi siabkua txobfeem ntau siv cov taum pauv organic thiab nplej uas tsis yog GMO. Cov khoom siv raw no yuav tsum ua raws li cov qauv ntawm tsis muaj tshuaj tua kab thiab tsis muaj chiv thaum lub sijhawm cog qoob loo. Lawv muaj cov protein ntau thiab saj ntshiab, tab sis tus nqi siab dua li cov khoom siv raw ib txwm muaj. Tus nqi qiskua txobfeem ntau siv cov khoom siv raw uas tsis yog organic lossis hloov kho caj ces uas pheej yig dua. Txawm hais tias nws tuaj yeem txo cov nqi tsim khoom, nws yuav ua rau cov khoom fermentedkua txobkom muaj qhov saj tsis zoo thiab qhov saj tom qab sib xyaw vim yog cov roj tsis sib npaug lossis muaj ntau yam tsis huv.
2. Tus nqi txheej txheem: qhov sib txawv ua los ntawm lub sijhawm
Ib txwm muajkua txobvam khom siv cov thev naus laus zis fermentation uas muaj ntsev ntau, uas yuav tsum tau siv ntau lub hlis lossis txawm tias ntau xyoo ntawm kev fermentation ntuj. Thaum lub sijhawm ua cov txheej txheem, cov protein taum pauv maj mam decomposes rau hauv cov amino acids los tsim cov saj umami sib xyaw, tab sis lub sijhawm thiab cov nqi zog ua haujlwm siab. Kev tsim khoom lag luam niaj hnub no siv cov khoom siv fermentation lossis kev npaj uas muaj ntsev tsawg, uas ua rau lub voj voog luv dua los ntawm kev tswj qhov kub thiab av noo tas li. Txawm hais tias qhov ua tau zoo dua, nws yuav tsum vam khom cov xim caramel, cov khoom ua kom tuab, thiab lwm yam kom ua rau cov saj nyias. Qhov yooj yim ntawm cov txheej txheem tau cuam tshuam ncaj qha rau hauv qhov sib txawv ntawm tus nqi.
3. Amino acid nitrogen: qhov kev ua si ntawm qhov tseeb umami thiab cuav umami
Amino acid nitrogen yog qhov qhia tseem ceeb rau kev ntsuas qhov saj umami ntawmkua txobFeem ntau, cov ntsiab lus ntawm nws cov khoom noj khoom haus ntau dua txhais tau tias muaj kev fermentation ntau dua. Txawm li cas los xij, qee cov khoom noj khoom haus pheej yigkua txobs raug ntxiv nrog sodium glutamate (MSG) lossis zaub protein hydrolysate (HVP). Txawm hais tias zaub protein hydrolysate muaj cov amino acids thiab lwm yam khoom xyaw, nws tuaj yeem ua rau kom muaj txiaj ntsig zoo dua hauv lub sijhawm luv luv. Hom "dag umami" no muaj ib qho kev txhawb nqa saj, thiab nws cov amino acid muaj pes tsawg leeg yuav tsis nplua nuj thiab sib npaug li cov amino acids hauv cov tshuaj ib txwm muaj.kua txobUa kom siavkua txobtuaj yeem tsim cov tshuaj tsw qab thiab cov as-ham uas nyuaj dua los ntawm kev ua kom cov kab mob fermentation, thiab kev ntxiv cov protein zaub hydrolysate yuav ua rau cov as-ham no yaj.
Ntxiv mus, thaum lub sijhawm tsim cov txheej txheem ntawm HVP, tshwj xeeb tshaj yog thaum hydrochloric acid siv rau hydrolysis, cov rog tsis huv hauv cov khoom siv raw yuav cuam tshuam nrog hydrochloric acid los tsim cov tshuaj chloropropane, xws li 3-chloropropanediol. Cov tshuaj no muaj kev lom mob hnyav thiab ntev, ua rau lub siab, lub raum, lub paj hlwb, cov ntshav ncig, thiab lwm yam, thiab kuj tseem yuav ua rau mob qog noj ntshav. Txawm hais tias cov qauv hauv tebchaws muaj kev txwv nruj rau cov ntsiab lus ntawm cov tshuaj lom xws li chloropropanol hauv cov protein hydrolysates cog, hauv kev tsim khoom tiag tiag, qee lub tuam txhab yuav dhau tus qauv rau cov tshuaj lom vim yog kev tswj hwm cov txheej txheem tsis zoo lossis cov txheej txheem kuaj tsis zoo.
Kev xaiv ntawm cov neeg siv khoom: kev sib npaug ntawm kev xav thiab kev noj qab haus huv
Ntsib nrogkua txobnrog rau qhov sib txawv ntawm tus nqi dav, cov neeg siv khoom tuaj yeem pom qhov tseem ceeb los ntawm daim ntawv lo.
Saib qib: cov amino acid nitrogen cov ntsiab lus ≥ 0.8g / 100ml yog qib tshwj xeeb, thiab qhov zoo txo tsawg zuj zus.
Txheeb xyuas cov txheej txheem: "kev ua kom ntsev ntau" zoo dua li "kev npaj" lossis "kev sib xyaw".
Nyeem cov khoom xyaw: daim ntawv teev cov khoom xyaw yooj yim dua, qhov kev cuam tshuam ntxiv tsawg dua.
Qhov sib txawv ntawm tus nqikua txobyog qhov kev ua si ntawm lub sijhawm, cov khoom siv raw, thiab kev noj qab haus huv. Tus nqi qis yuav pab txuag tau cov nuj nqis tam sim ntawd, tab sis tus nqi ntawm kev noj qab haus huv mus sij hawm ntev tseem tsis tau raws li tus nqi ntsuas tau.
