Txoj kev loj hlob ntawm cov khoom noj khoom haus sweetener kev lag luam tau nyiam heev los ntawm cov tuam tsev, cov kws tshaj lij, cov kws tshawb fawb, thiab cov kws tshaj lij kev lag luam. Feem ntau, nws tsim cov nyhuv synergistic, yooj yim rau nws daim ntawv thov hauv kev lag luam khoom noj khoom haus, thiab tsim cov xwm txheej rau cov tuam txhab siv cov khoom noj khoom haus raws li cov qauv. Qhov no yuav txhaj tshuaj tshiab tseem ceeb rau hauv kev tsim cov khoom noj qab zib sib xyaw. Peb ntseeg hais tias nrog kev xav tau ntau ntxiv rau ntau haiv neeg, noj zaub mov zoo, thiab siab - cov khoom noj khoom haus zoo, cov khoom qab zib sib xyaw ua ke yuav dhau los ua cov kev taw qhia thiab cov qauv ntawm kev lag luam khoom noj qab zib, tsav txoj kev loj hlob sai ntawm kuv lub teb chaws kev lag luam kev lag luam, kev lag luam zaub mov, thiab lwm yam lag luam.
Compound sweeteners yog khoom noj khoom haus additives uas muaj ob los yog ntau dua sweeteners nyob rau hauv ib tug scientific formulated piv. Lawv lub hom phiaj tseem ceeb yog txhawm rau txhim kho cov yam ntxwv qab zib, txo cov nqi, lossis txhim kho cov txiaj ntsig kev noj qab haus huv los ntawm kev sib koom ua ke. Piv nrog rau cov khoom qab zib ib txwm muaj, cov khoom qab zib tuaj yeem npog qhov tsis kaj siab tom qab (xws li iab ntawm aspartame thiab lub siab tshiab ntawm qab zib cawv) los ntawm kev sib cuam tshuam, thaum siv qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm cov khoom qab zib sib txawv kom ua tiav qhov saj ze dua rau sucrose. Piv txwv li, kev sib xyaw ua ke ntawm sucralose thiab erythritol ib txhij tuaj yeem muab cov khoom qab zib thiab calories tsawg, ua rau nws haum rau cov suab thaj - dej haus dawb; thaum sib xyaw ua ke ntawm acesulfame potassium thiab aspartame tuaj yeem ua rau lub sijhawm ua kom qab zib thiab feem ntau siv hauv cov khoom ci.
Los ntawm kev pom kev, kev tsim cov khoom qab zib sib xyaw yuav tsum xav txog cov khoom qab zib qhov pib, qhov siab tshaj plaws qab zib concentration, thiab kev sib koom ua ke. Cov kev tshawb fawb tau pom tias cov nyhuv synergistic yog qhov tseem ceeb tshaj plaws thaum qhov sib piv ntawm ob lub qab zib yog 1: 3 txog 1: 5, uas tuaj yeem txo qhov ntau npaum li 20% -30%. Hais txog cov qauv kev lag luam, GB ... GB / T 2760-2014, "Standard for the Use of Food Additives," qhia meej txog cov khoom siv ntau thiab kev siv ntau tshaj plaws ntawm cov khoom qab zib. Piv txwv li, hauv cov dej haus carbonated, tag nrho kev siv cov khoom qab zib yuav tsum tsis pub tshaj 0.5 g / kg.
Nyob rau hauv cov nqe lus ntawm daim ntawv thov scenarios, compound sweeteners tau nkag mus rau hauv dej haus, khoom noj siv mis, confectionery, thiab noj qab haus huv sectors. Hauv cov suab thaj- cov dej tshuaj yej dawb, cov khoom qab zib tuaj yeem hais txog qhov teeb meem raws plab uas cuam tshuam nrog ib qho khoom qab zib (xws li xylitol); nyob rau hauv tsawg- rog yogurt, lawv muaj peev xwm them rau cov dryness tshwm sim los ntawm txo cov roj cov ntsiab lus. Nws yog ib nqi sau cia hais tias txawv pH ib puag ncig cuam tshuam rau stability ntawm compound sweeteners. Kev soj ntsuam zoo muaj qhov cuam tshuam loj heev- acidic tej yam kev mob (pH <4) yuav ua rau kom cov hydrolysis ntawm qee cov khoom qab zib (xws li cyclamate), thaum ib puag ncig nruab nrab (pH 6-7) yog qhov zoo dua rau kev khaws cia ntev.
Nyob rau hauv cov nqe lus ntawm cov txheej txheem ntau lawm, compound sweeteners xav tau peb kauj ruam: sib tov, granulation, thiab ziab. Kev sib xyaw ua ke yuav tsum tau sim siv laser diffraction los xyuas kom meej qhov loj me me faib D90 < 100 μm; cov txheej txheem granulation yuav tsum tswj cov dej noo kom <5% txhawm rau tiv thaiv clumping. Cov ntim ntim ntim yog siv rau hauv lub ntim ntim kom zoo cais cov av noo (pom zoo cia ib puag ncig cov av noo <60%), txuas lub neej txee rau 24 lub hlis.
