L-Cysteine hydrochloride monohydrate CAS 7048-04-6
L-Cysteine Hydrochloride Monohydrate (CAS 7048-04-6) yog ib qho tseem ceeb uas muaj sulfur-muaj amino acid derivative siv dav hauv cov khoom noj, tshuaj, tshuaj pleev ib ce, thiab kev siv hauv kev lag luam. Nws cov txiaj ntsig tseem ceeb yog los ntawm pawg sulfhydryl (-SH) uas nyob hauv lub molecule, uas muab nws cov khoom txo qis, antioxidant, thiab bioregulatory.

1. Kev Lag Luam Khoom Noj
(1) Cov Khoom Siv Khob Noom Uas Zoo Dua: Los ntawm kev rhuav tshem cov disulfide bonds ntawm cov protein hmoov nplej, nws ua rau cov khob noom cookie nthuav dav thiab ua kom zoo dua qub, txhim kho qhov mos thiab tiv thaiv kev laus ntawm cov mov ci thiab noodles, thiab qhov ntxiv feem ntau tsis pub tshaj 0.06g / kg.
(2) Tshuaj Antioxidant thiab Xim Tiv Thaiv: Tiv thaiv enzymatic browning (xws li polyphenol oxidase) ntawm cov txiv hmab txiv ntoo, zaub, thiab nqaij, ua kom lub txee ntev dua; tswj cov vitamin C hauv cov kua txiv hmab txiv ntoo ntuj thiab tiv thaiv oxidative discoloration.
(3) Cov Khoom Qab Zib: Koom nrog Maillard cov tshuaj tiv thaiv los tsim cov tshuaj tsw qab hauv nqaij thiab cov khoom qab zib, txhim kho cov saj ntawm cov zaub mov.
2. Tshuaj pleev ib ce thiab kev saib xyuas tus kheej
(1) Cov Khoom Siv Saib Xyuas Plaub Hau: Tswj cov keratin disulfide bonds, kho cov perm thiab cov xim puas tsuaj, txo cov plaub hau poob, thiab siv rau hauv cov tshuaj zawv plaub hau thiab cov tshuaj pleev plaub hau.
(2) Kev Saib Xyuas Tawv Nqaij: Tshem tawm cov dawb radicals uas ua rau muaj UV thiab ntxiv rau cov tshuaj pleev thaiv hnub thiab cov khoom tiv thaiv kev laus kom ncua kev puas tsuaj rau daim tawv nqaij. 3. Cov khoom noj khoom haus thiab cov khoom noj ntxiv rau pub tsiaj
(1) Cov tshuaj noj qab haus huv: Ua ib qho tseem ceeb amino acid precursor, siv rau hauv cov tshuaj noj kis las thiab mis mos rau menyuam yaus los txhawb kev kho cov leeg thiab kev ua haujlwm ntawm lub cev tiv thaiv kab mob.
(2) Daim ntawv thov pub tsiaj: Ntxiv cov amino acids uas muaj sulfur (hloov methionine) los txhawb kev loj hlob ntawm cov tsiaj txhu thiab cov nqaij qaib.
4. Kev lag luam thiab lwm yam
(1) Kev tsim tshuaj lom neeg: Ua ib qho thiol reagent, siv los tsim cov tshuaj intermediates xws li N-acetylcysteine (NAC).
(2) Cov ntawv thov kev tshawb fawb: Kev cog qoob loo ntawm cov kab mob anaerobic, cov tshuaj reagents nrhiav hlau hnyav, thiab lwm yam.
