Thaum nws los txiav txim siab txog kev ua kom huv, cov neeg siv khoom lub tswvyim qee zaum tseem ceeb dua li lawv muaj keeb kwm.
Hydrocolloids ua si lub luag haujlwm loj hauv kev txhim kho khoom noj thiab dej haus. Cov khoom xyaw no tuaj yeem txhim kho qhov qab, viscosity, kev ntxhib los mos, ruaj khov thiab ntau lwm yam ntxwv ntawm cov zaub mov tiav.
Yog lawm, cov tuam txhab ua khoom noj yuav ua tib zoo xaiv lawv cov hydrocolloids thaum tsim cov khoom lag luam tshiab, suav nrog ntau" huv si" thiab" zoo-rau-koj" cov khoom lag luam nyob rau ntawm kev ua lag luam.
Tab sis txhua yam feem ntau zoo li qhov no: txiav txim siab uas hydrocolloids haum rau" daim ntawv huv" thiab uas tsis yog tsis yog kev kawm tseeb. Qhov tseeb, lub luag haujlwm ntawm kev tshawb fawb feem ntau tsis zoo raws li kev pom.
GG quot;&# 39 yog dab tsi; Daim ntawv lo huv'? Qhov no yog ib lo lus nug nyuaj los teb. Qhov no txhais tau tias cov neeg siv khoom sib txawv muaj cov kev xav sib txawv." DuPont Khoom noj khoom haus thiab Biosciences khov khoom noj qab zib daim ntawv thov tus thawj coj Aaron Venables (AaronVenables) Hais.
Iliana Nava, tus kws tshaj lij pabcuam kev ua haujlwm ntawm Cargill, pom zoo:"' Daim ntawv lo huv' yog ib lo lus dav heev uas txhais tau hais tias muaj ntau yam sib txawv rau cov neeg sib txawv."
Piav qhia txog scientific
Hydrocolloids yog cov saw ntev polymers uas ua rau cov dej tawg lossis cov nplauv zoo nkauj thaum tov nrog dej. Qhov no yog cov cuab yeej yooj yim ntawm hydrocolloids uas muaj txiaj ntsig rau cov khoom noj thiab dej haus, tab sis cov khoom ntawm hydrocolloids muaj kev hloov pauv tsis kawg.
GG quot; Txawm hais tias ntau yam hydrocolloids koom nrog rau ua ke nrog cov khoom sib txawv, lawv cov khoom ntiag tug yuav txawv heev." Tate& Lyle Group (Tate& Lyle) kua zaub thiab kua zaub EMEA tus neeg saib xyuas kev pabcuam Olaf Koenke (OlafKohnke) hais tias, "Piv txwv, siv tib lub koob tshuaj sib txawv ntawm ntau qhov chaw thiab hom ntawm cov pos hniav guar tuaj yeem muab ntau yam viscosities thiab txawv dej-khi muaj peev xwm. Txawm li cas los xij, nyob rau hauv kev tshaj tawm cov khoom xyaw, tag nrho cov no muaj npe' guarana Bean Gum' daim ntawv lo."
Cov Khoom Noj Zoo' Feida Dib Kua Yogurt Dip muaj pectin, carob, xanthan ntawm cov pos hniav thiab cov pos hniav guar txhawm rau txhim kho kev ntxhib los mos ntawm cov khoom.Mixing hydrocolloids yuav hloov lawv cov hom kev ua.
Ntxiv rau cov khoom ntiag tug ntawm hydrocolloids, kuj tseem muaj ntau cov teebmeem synergistic sib txawv ntawm hydrocolloids. Piv txwv li, xanthan ntawm cov pos hniav thiab locust taum cov pos hniav (tseem hu ua carob taum cov pos hniav) txhua cov khoom tsim viscosities hauv kev daws teeb meem. Txawm li cas los xij, kev sib txuas ntawm ob hom tshuaj colloids no yuav tshwm sim sai li sai tau. Cov teebmeem synergistic no yog qhov nyuaj, yog li nws nyuaj heev kom pom qhov kev sib txuam zoo tshaj plaws ntawm txhua hom zaub mov.
Kev ntxuav yog dab tsi?
Txij li cov khoom noj khoom haus ib txwm xav tau hydrocolloids los ua ntau yam hauv ntau hom kev sib txuas, nws tsis yog qhov nyuaj rau nkag siab yog vim li cas lawv feem ntau tig mus rau ntau yam hydrocolloids kom tau raws li kev xav tau tshwj xeeb, uas tsis meej pem lub sij hawm" huv" ;.
Qee qhov hydrocolloids yog cov khoom ua rau ntuj, xws li pos hniav, polysaccharide pom hauv cov txiv hmab txiv ntoo; los yog arabic ntawm cov pos hniav, cov pos hniav muab tau los ntawm tsob ntoo acacia. Lawv tuaj yeem yooj yim ua ib feem ntawm daim ntawv lo huv, tsis tsuas yog vim tias lawv yog ntuj, tab sis kuj vim tias feem ntau cov neeg siv khoom tau sib hais cov lus no.
Pectin yog tus neeg sawv cev muag khoom uas tuaj yeem tswj tau cov khoom noj siv mis. Nws tau pom tias muaj ntau yam kev tiv thaiv protein hauv cov khoom noj pH tsawg. Pectin yuav ua raws li cov txheej txheem sab nraud ntawm cov protein, ua rau cov khoom muag du thiab ruaj khov.
GG quot; Qee qhov starches tau hloov kho vim raug neeg xav kom lawv muab cov haujlwm sib txawv." Nava tau hais tias," piv txwv li, nws muaj peev xwm tiv taus siab kub lossis siab sib xyaw ua ke."
Feem ntau, txawm hais tias hloov hmoov txhuv nplej siab nws tus kheej tsis zoo, nws tsis suav hais tias yog kev ntxuav kom huv.Tab sis huv thiab tsis huv tsis yog ob qho chaw pw hav zoov uas tawm tsam txhua yam. Nqa cov carrageenan ua piv txwv.Cov hydrocolloid no yog muab rho tawm los ntawm seaweed thiab tau siv hauv kev ua noj hauv ntuj rau ntau pua xyoo. Nws yog ib tus neeg sawv cev gelling, tab sis tsis zoo li gelatin ntawm cov tsiaj keeb kwm, nws yog cog-raws thiab haum rau cov neeg tsis noj nqaij.
Cov chaw tau hais tias:" Carrageenan tau raug suav tias yog' tsis huv' khoom xyaw rau xyoo dhau los lossis xya xyoo, tab sis nws yog 100% ntuj. Qhov laj thawj yog vim li cas nws tau raug ntaus yog vim qee qhov kev lav ris kev ywj pheej. Cov kev tshawb fawb pom tau tias carrageenan muaj qee cov teeb meem kev noj qab haus huv."
Nws tau hais:" Peb tau ua peb tus kheej tshawb fawb thiab koom tes nrog tsoomfwv los ua pov thawj nws qhov kev nyab xeeb tiag tiag. Txawm li cas los xij, pab pawg tsawg tus neeg muaj lub suab nrov thiab lawv tau thov tias carrageenan yog cov carcinogenic. Tab sis qhov no yog me nyuam mos mis. Ib hom hydrocolloid ua lub zog!"
Yuav ua li cas hais txog biosynthetic hydrocolloids, xws li xanthangum thiab gellangum? Ob qho tib si muab tau los ntawm cov khoom xyaw ntuj thiab dhau los ua hydrocolloids thaum lub txheej txheem fermentation. Gellan cov pos hniav yog suav hais tias yog daim ntawv ntshiab los ntawm feem ntau cov neeg siv khoom Asmeskas, thaum xanthan ntawm cov pos hniav feem ntau tsis yog. vim li cas? Cov Venables xav hais tias nws yog vim nws lub npe.
Nws hais tias:" Cov neeg tsis txhob' t xav tias xanthan ntawm cov pos hniav huv vim nws muaj X nyob rau pem hauv ntej. Qhov no tsuas yog qhia yuav ua li cas irrational neeg qee zaum xav txog teeb meem. Tab sis peb yuav tsum ua raws li kev ua lag luam."
Hauv Cov Khoom Siv Tsis Muaj Teeb Meem' Cov khoom tsis yooj yim Burgers, ob qhov hydrocolloids, xanthan ntawm cov pos hniav thiab cov pos hniav konjac, yog siv.
Tsim daim ntawv lo huv
Raws li taw qhia los ntawm Venables thiab Nava," huv ntawv cim" muaj ntau lub ntsiab lus, yog li los tsim cov khoom noj nrog cov ntawv lo huv, xyuam xim rau xaiv cov khoom xyaw zoo.
Piv txwv li, rau ntau tus neeg, cov ntawv lo huv si yog cov ntawv cim luv nrog cov khoom sib xyaw. Qhov no txhais tau tias tshem tawm cov khoom xyaw uas tsis tsim nyog thiab hloov cov khoom xyaw nrog cov npe science ntev dua nrog cov sib xyaw nrog ntau dua nrog kev ua haujlwm ib yam.
GG quot; Hais txog kev paub, cov neeg twb paub ntau yam hydrocolloids," Nava hais tias. Pectin yog ib tus ntawm lawv. Cov neeg tau paub pectin ntev ntev, thiab koj tuaj yeem pom nws hauv chav ua noj hauv tsev.
Cov hmoov txhuv nplej siab tseem yog hydrocolloid paub. Nava tau hais tias Cargill' s SimPure ua haujlwm cov hmoov txhuv nplej siab (suav nrog cov pob kws thiab cov hmoov txhuv nplej siab) yog cov khoom lag luam zoo.
BeyondBurger los ntawm BeyondMeat muaj cov hmoov txhuv nplej siab, uas ntxiv cov khoom tu rau nws cov npe ntev ntev. Lwm qhov hydrocolloid uas tsis yog hamburgers yog methyl cellulose, uas yog cov tshuaj los ntawm kev hloov tshuaj rau cov nroj tsuag cellulose thiab tsis suav hais tias yog daim ntawv lo huv.
Ntawm chav kawm, lwm qhov kev to taub feem ntau ntawm" cov ntawv huv" yog tias cov khoom xyaw no suav hais tias yog noj qab haus huv tsis hais seb lawv puas paub hauv chav pantry lossis tsis zoo.
Berliner los ntawm ISCGums tau hais tias:" Cov khoom muaj nuj nqi ntxiv xws li organic, tsis-GMO, thiab kev ruaj khov yog qhov xav tau loj." Cov pos hniav arabic yog hydrocolloid hauv pawg no. Tej zaum yuav tsis muaj lub hwj tshuaj ntawm cov pos hniav hauv ib tsev neeg khob khob, tab sis kev tshawb fawb pom tau tias nws yog cov khoom xyaw ntuj thiab noj qab nyob zoo.
Qhov kev thov rau cov pos hniav arabic tau nce ntau heev, vim tias tsis zoo li hloov khoom noj khoom qab zib thiab lwm yam kev hloov pauv ntawm cov pos hniav, cov pos hniav arabic nthuav tawm tag nrho cov yam ntxwv ntawm daim ntawv lo huv.
Thaum kawg, rau qee cov tib neeg, cov ntawv lo huv yog cov ntawv lo qhia txog kev paub, kev noj qab haus huv, thiab kev sib raug zoo thiab ib puag ncig.
Tammy Reinhart, Tus Thawj Coj Lag Luam Thoob Ntiaj Teb ntawm Tate& Lyle' s kev Ruaj Ntseg thiab Kev Ua Haujlwm Zoo, hais tias:" Niaj hnub no, qhov peb pom tsis yog' ntawm' huv duab'. , Nws suav nrog kev ruaj khov, qab qab zib qis, ntsev qis, cog qoob loo, noj qab haus huv thiab khoom noj khoom haus, thiab cov khoom lag luam uas yuav tsis muaj qhov tsis zoo rau tib neeg lossis ib puag ncig." ;.
Lub hydrocolloid ua tau li cas tag nrho cov kev xav tau ntawm cov paib no? Reinhart ntseeg tias qhov no yog qhov muaj peev xwm xav tau teeb meem rau cov neeg ua khoom noj khoom haus.
Nws tau hais tias:" Los ntawm peb cov kev tshaj lij cov khoom lag luam zoo thiab cov khoom siv ua khoom noj khoom muaj peev xwm, peb tuaj yeem pab cov neeg siv khoom tsim cov khoom lag luam kom haum rau cov neeg siv khoom' lub ntsiab lus ntawm' huv si'."
Niaj hnub no, cov neeg siv khoom nyiam cov ntawv sau huv, tshwj xeeb yog zaub mov thiab dej haus uas tau lees tias yog qhov zoo rau ib puag ncig. Xaiv cov hydrocolloid tseeb kom ua tiav cov txiaj ntsig yam xav tau ntawm cov khoom thiab daim ntawv lo tsis tas yuav tsum muaj kev nkag siab ntawm zaub mov khoom noj khoom haus, tab sis kuj tseem paub txog cov neeg siv khoom.
