Dab tsi yog cov yam ntxwv thiab kev siv ntawm polydextrose?

Polydextrose yog ib qho tshwj xeeb uas muaj calorie tsawg thiab glycemic Performance index tsawg. Nws muaj cov yam ntxwv ntawm dej-soluble dietary fiber thiab prebiotics. Nws yog tsim los ntawm ib txwm muaj suab thaj thiab ib qho me me ntawm sorbitol thiab citric acid los ntawm kev kub-kub melting thiab polycondensation. Nws yog randomly sib txuas. Ib qho polysaccharide tsim los ntawm qabzib.

Polydextrose muaj ntau yam "tus kheej". Qhov thib ib yog cov khoom noj khoom haus, thiab qhov thib ob yog cov khoom noj khoom haus ntxiv. Polydextrose yog siv los ua tus neeg sawv cev thickening, leavening agent, dej tuav tus neeg sawv cev, thiab stabilizer, thiab muaj ntau yam kev siv thiab tsis txwv; polydextrose tuaj yeem siv los ua khoom noj khoom haus fortifier rau cov menyuam mos thiab menyuam yaus. Hauv cov qauv, kev siv nyiaj yog 15.6-31.25 g / kg.

Cov yam ntxwv zoo kawg li

1. Dej solubility: Polydextrose yog yooj yim soluble nyob rau hauv dej thiab muaj peev xwm yaj txog 80% thaum kub nce mus txog 25 degree, thiab solubility muaj zog thaum kub nce. Sib txawv ntawm cov fibers zoo tib yam, polydextrose yaj sai dua. Yog tias cov zaub mov qib KHCO3 (potassium bicarbonate) ntxiv rau daim ntawv polydextrose-K, qhov kev sib cais ceev yuav ntxiv mus.

2. Kev daws viscosity: Nyob rau tib lub concentration, viscosity ntawm polydextrose kua yog siab dua li ntawm sucrose tov thiab sorbitol tov. Nws cov viscosity txo qis nrog qhov kub thiab txias, uas zoo ib yam li cov tshuaj sucrose, yog li cov saj thiab kev ntxhib los mos ntawm polydextrose hauv cov zaub mov tuaj yeem hloov cov piam thaj lossis lipids.

3. Moisturizing vaj tse: Thaum qhov kub thiab txias yog qhov siab, polydextrose yuav nqus dej tag nrho thaum nws nyob hauv lub xeev ruaj khov, yog li nws kuj tuaj yeem siv los ua tus neeg sawv cev moisturizing los tswj cov av noo ntawm cov khoom noj thiab ua kom muaj cov nyhuv antiseptic.

4. Saj: Polydextrose nws tus kheej tsis muaj qab zib, tab sis nws tuaj yeem siv nrog cov khoom qab zib siab thiab cov calories tsawg los ua cov khoom qab zib tsawg.

5. Kev ruaj ntseg: Polydextrose yog qhov ruaj khov heev, thiab nws nyuaj rau cov kab mob kom muaj sia nyob hauv nws. Thaum tus txheeb ze humidity yog 75%, qhov concentration yuav poob mus rau 80%; Thaum tus txheeb ze humidity yog 52%, qhov concentration tuaj yeem txo mus rau 90%. Kev khaws cia ntev ntev ntawm qhov kub siab yuav ua rau cov xim tsaus, yog li nws yuav tsum tau muab cia rau hauv lub thawv kaw ntawm qhov kub qis.

Kev siv ntau yam: Polydextrose tuaj yeem siv rau hauv cov nqi tsim nyog hauv cov khoom npaj thiab npaj ua kua raws li kev xav tau ntau lawm. Vim tias polydextrose muaj tus nqi qis-calorie, nws tuaj yeem siv los tsim cov khoom noj tsis muaj zog, slimming noj qab haus huv.

1. Yogurt: Raws li dej-soluble dietary fiber nrog kev noj qab haus huv muaj nuj nqi, polydextrose feem ntau yog ntxiv rau cov khoom siv mis nyuj los txhim kho cov khoom noj khoom haus thiab kev noj qab haus huv thiab saj ntawm cov khoom siv mis nyuj.

Covpolydextrose thiab cov suab thaj dawb tau sib xyaw ua ke hauv qhov sib piv ntawm 4: 5 thiab tom qab ntawd ntxiv rau cov mis nyuj tshiab rau fermentation los ua yogurt. Nws tau pom tias curd yog ib yam tsis muaj whey nag lossis daus, xim yog dawb porcelain, tsw thiab saj zoo, thiab nws muaj peev xwm txhawb kev tsim cov yogurt. Kev loj hlob ntawm cov kab mob lactic acid nyob rau hauv yogurt hloov lub koom haum lub xeev ntawm cov khoom, txhim kho cov tsw ntawm cov mis nyuj, thiab muaj cov nyhuv ntawm kev txhawb kev loj hlob ntawm bifidobacteria, uas muaj peev xwm ntxiv cov khoom noj khoom haus thiab kev noj qab haus huv lub luag hauj lwm ntawm yogurt thiab zoo heev txhim kho qhov zoo ntawm cov kab mob. yogurt.

2. Cov dej khov nab kuab: Polydextrose yog qhov tsim nyog rau kev ua haujlwm dej khov vim nws cov lipid hloov ua haujlwm zoo. Ntawm qhov chaw ntawm kev khaws lwm cov khoom xyaw tsis hloov, 20% thiab 40% ntawm margarine tau hloov nrog polydextrose, thiab qhov nthuav dav thiab lwm yam ntsuas tau ntsuas.

Polydextrose tuaj yeem hloov tau ib feem ntawm cov rog hauv cov dej khov thiab tsis muaj qhov cuam tshuam rau qhov saj thiab kev ntxhib los mos ntawm ice cream. Cov txheej txheem kev ua tau zoo kuj zoo ib yam li cov khoom siv khov nab kuab uas tsis hloov pauv, tab sis cov calories tau txo qis.

3. Cov khoom ci: Polydextrose kuj tau siv dav hauv cov khoom ci xws li ncuav mog qab zib. Hauv qee qhov kev sim, polydextrose thiab acesulfame potassium tau siv ua ke los hloov 25%, 50%, 75%, thiab 100% ntawm sucrose hauv ncuav. Qhov kev sim ua pov thawj tias qhov chromaticity ntawm cov khoom hloov pauv yog me ntsis sib dua li ntawm cov khoom tsis hloov pauv, thiab tus nqi pH txawv. Tsis loj, tag nrho ib ncig ntawm 5.4.

Cov txiaj ntsig tau pom tias tom qab kev hloov pauv, cov khoom lag luam muaj kev ntxhib los mos thiab zoo noo noo tuav, zoo ib yam li cov khoom ua ntej hloov, thiab lub ncuav mog qab zib ntim yog loj dua li ntawm cov qauv yam tsis muaj kev hloov pauv, uas yog, qhov kev nthuav dav yog loj, thiab cov tsos yog indistinguishable, saj yog zoo, thiab nws muaj ib tug zoo tsw. ; Qhov loj dua qhov hloov pauv, qhov zoo dua elasticity thiab me dua qhov hardness. Yog li ntawd, polydextrose tuaj yeem hloov sucrose hauv kev tsim cov ncuav qab zib tsawg.

4. Khoom qab zib: Polydextrose kuj yog ib qho khoom zoo rau cov khoom qab zib tsis muaj qab zib. Nws cov dej solubility siab thiab viscosity siab tuaj yeem ua kom zoo chewiness ntawm cov khoom qab zib nyuaj thiab cov khoom qab zib gummy; cov yam ntxwv ntawm kev tiv thaiv crystallization ua rau nws haum rau cov khoom qab zib cawv cawv.

5. Dej haus:Polydextrosemuaj cov khoom zoo heev xws li dej solubility zoo, tsis muaj pH tus nqi, siab ruaj khov nyob rau hauv cov cua kub, stability thaum lub sij hawm txee lub neej, thiab tsis muaj fiber ntau poob. Nws yog dav siv hauv cov khoom siv dej haus (nrog rau cov dej haus), tsis muaj saj tsis zoo, xim, thiab luster. thiab clarity, thiab txhim khu cov saj ntawm cov suab thaj tsis muaj qab zib los yog cov dej qab zib tsawg.
