ASPARTAME
Kev Taw Qhia
Aspartame yog ib yam khoom qab zib dag, uas yog ib qho amino acid dipeptide derivative. Nws tau tshawb pom los ntawm cov kws tshuaj xyoo 1965 thaum tsim cov tshuaj kho mob ulcer. Nws muaj qhov zoo ntawm kev noj tsawg, qab zib ntau, saj zoo, tuaj yeem txhim kho qhov saj ntawm txiv qaub thiab lwm yam txiv hmab txiv ntoo, txo cov calories, tsis muaj caries, thiab tsawg dua lom dua li cov khoom qab zib dag xws li saccharin.
Cov khoom siv tshuaj lom neeg
Cov hmoov crystalline dawb, tsis muaj ntxhiab, qab zib heev, qab zib ntshiab, qab zib 100 ~ 200 zaug ntawm sucrose Melting point 235 ℃ (decomposition). Nws muaj cov khoom zoo li cov amino acids. Nws ruaj khov nyob rau hauv qhuav mob lossis nyob rau hauv qhov ntau ntawm Ph nqi ntawm 2 txog 5. Nws tuaj yeem hydrolyzed los tsim cov monomer amino acids nyob rau hauv ib qho muaj zog acidic aqueous kua.
SIV
Aspartame yog ib qho kev sib xyaw ua ke ntawm L-aspartic acid thiab L-phenylalanine. Lub dipeptide tuaj yeem nqus tau thiab metabolized los ntawm lub cev tib neeg. Nws tsis muaj tshuaj lom thiab tsis ua rau muaj kev phom sij, muaj kev nyab xeeb thiab txhim khu kev qha. Qhov saj yog ntshiab thiab txias. Nws saj zoo li sucrose, tab sis qhov qab zib yog 200 npaug ntawm sucrose, thiab calorie tsuas yog 1/200 ntawm sucrose. Kev noj zaub mov tsis tu ncua tsis ua rau muaj hniav, tsis cuam tshuam rau cov ntshav qab zib, thiab tsis ua rau rog dhau, ntshav siab, mob plawv. Nws tau ntxiv rau ntau yam khoom noj, cov khoom lag luam thiab txhua yam dej qab zib thiab dej haus, thiab ntau dua 4,000 hom aspartame tau siv. Nws tuaj yeem siv ua cov khoom noj khoom haus ntxiv thiab cov khoom qab zib muaj txiaj ntsig nrog qhov qab zib siab.
