Daim ntawv thov ntawm pectin

Pectin yog siv dav hauv kev lag luam kws tshuaj thiab zaub mov noj. Cov tshuaj pectin pab ua kom zoo tshem cov hlau ions hnyav, tshuaj tua kab thiab lwm qhov sib xyaw ua kom tsis zoo ntawm lub cev, nrog rau kev txhim kho txoj haujlwm ntawm lub plab zom mov. Kws tshuaj muaj nyob hauv ntuj coj los tiv thaiv mob thiab qhov mob kom zoo.

Vim tias cov qauv tsim qauv-yam ntxwv ntawm pectin, nws thiaj li siv tau nws los ua cov tshuaj uas muaj peev xwm ntawm cov tshuaj encapsulating.

Hauv kev lag luam khoom noj khoom haus, pectin siv los ua cov thickener hauv kev tsim cov marshmallows, ice cream, marmalade, jelly, khaub noom puv thiab kua txiv haus. Raws li lub ntuj tso rau, nws yog tsim E440. Muaj 2 hom pectin - ua kua thiab hmoov. Ua raws li daim ntawv ntawm pectin khoom, qhov sib lawv liag ntawm kev sib xyaw ntau yam khoom hauv cov txheej txheem ntawm lawv cov kev npaj tau ua. Cov kua pectin tau ntxiv rau qhov kub kub uas nyuam qhuav dhau los, thiab hmoov pectin ntxiv rau cov kua txiv lossis kua txiv. Ntim pectin yog qhov zoo tagnrho rau kev ua kua jelly thiab marmalade los ntawm cov txiv hmab txiv ntoo thiab txiv ntseej.

Ntawm kev lag luam nplai, cov tshuaj pectin tau txais los ntawm cov kua thiab txiv qaub pomace, qab zib beet pulp thiab paj noob hlis.

Tseem ceeb thaj chaw ntawm pectin

Lub ntuj tso kom muaj lub cev - qhov no yog dab tsi kws kho mob hu ua pectin. Kev noj haus cov tshuaj fiber ntau, uas yog pectin, muaj peev xwm ua kom tshem tawm cov tshuaj lom neeg thiab cov khoom tsis zoo ntawm cov nqaij mos: cov tshuaj tua kab, cov khoom ua pa, cov hlau hnyav. Nws yog yam ntxwv tias qhov tsis sib luag ntawm cov kab mob bacteriological hauv lub cev tsis ntxhov siab.

Pectin tseem ceeb txhim kho lub plab hnyuv microflora, muaj kev txhim kho thiab tiv thaiv kev cuam tshuam ntawm lub plab hnyuv hauv lub qhov txhab mob, ua rau cov mob muaj txiaj ntsig rau microbiocenosis - cov txheej txheem ntawm kev tsim tawm ntawm microbes uas muaj txiaj ntsig rau lub cev.

Qhov tsis tau txais txiaj ntsig ntawm pectin yog vim nws cov txiaj ntsig ntawm cov metabolism. Nws muaj kev koom tes hauv kev hloov kho cov txheej txheem redox, txhim kho peripheral ncig, ua kom lub plab hnyuv, thiab txo cov ntshav cov roj kom ntshav tsawg.

Qhov feem ntau txhua hnub ntawm pectin, thaum muaj kev txo qis tseem ceeb hauv cov ntshav roj, yog 15 grams. Nws zoo dua yog tias lub cev tau txais tus nqi no tsis yog los ntawm cov tshuaj pectin, tab sis los ntawm cov tshiab, qhuav los yog cov kaus poom thiab txiv hmab txiv ntoo.

Pectin hauv cov khoom

Cov khoom siv feem ntau ntawm pectin yog txiv apples, pears, txiv tsawb, hnub, txiv duaj, txiv plooj, blueberries, figs, txiv hmab txiv ntoo (nws yog qhov tshwj xeeb tshaj yog nyob rau hauv cov txiv ntseej peels - txog 30%). Tsawg me ntsis pectin pom nyob rau hauv cov txiv pos nphuab, txiv ntoo qab zib, ntoo thuv, blueberries, melon, thiab taum ntsuab.

Cov Yuav Tsum Tau Ua

Tau txais kev noj tshuaj tshaj plaws ntawm pectin los ntawm cov khoom siv ntuj yog yuav luag tsis yooj yim. Txawm li cas los xij, nrog kev siv ntau dhau ntawm nws, nws yog ib qho ua tau kom txo qhov nqus ntawm cov zaub mov xws li calcium, magnesium, iron thiab zinc. Tsis tas li, txheej txheem ntawm assimilation ntawm cov nqaijrog thiab cov rog ntxiv yuav cuam tshuam me ntsis thiab fermentation yuav pib nrog cov tsos ntawm cov roj cua hauv txoj hnyuv (ua kom lub ntsej muag).
