Nws tsis tuaj yeem niaj hnub no los xav txog kev lag luam khoom noj niaj hnub yam tsis muaj tshuaj ntxiv. Nyob rau hauv lub ntim ntawm cov khoom feem ntau muaj cov ntaub ntawv hais txog cov muaj pes tsawg leeg. Thiab nws yog qhov zoo yog tias tsuas muaj cov lus uas peb paub txog "cov hmoov nplej, qab zib, butter …". Tab sis feem ntau muaj cov ntsiab lus tsis nkag siab yog qhov tsis txaus ntseeg. Yuav ua li cas paub nws?

"E" yog dab tsi?

Muaj ntau yam ntxiv. Txhua tus nyob hauv ib chav kawm muaj kev phom sij. Nov yog qee qhov piv txwv:

  1. Tus kws kho mob lossis mis nyuj hnyuv ntxwm nyiam ntau yam nrog cov xim liab dawb. Ib qho ntxoov ntxoo appetizing tsis yog los ntawm cov nqaij hauv nws cov muaj pes tsawg leeg, tab sis los ntawm cov khoom noj khoom haus ntxiv sodium nitrite E250.
  2. Cij los yog lwm yam pastry yuav tsis fluffy nrog fluffy crumb rau ob peb hnub ua ke yog tias koj tsis ntxiv cov khoom uas khaws cov dej noo (glycerin E422, sorbitol E420).
  3. Cov kua zaub tsw qab tshaj qhov ua rau ntawm cov kua zaub nrog lub voos xwmfab "Maggi", tej zaum tsis nyob hauv ntiaj teb. Yog vim li cas yog qhov paub zoo saj txhim kho monosodium glutamate E621. Nws tuaj yeem pom hauv ntau cov khoom noj ntsim, ntsev.
  4. Hiav txwv kale, ntses haus luam yeeb, qee cov cheese thiab ntau ntxiv tuaj yeem thov khaws cia ntev, yog tias tsis muaj tshuaj tua kab mob (sodium benzoate E211, sorbic acid E200).

Flavors, anti-caking agents, leavening agents, emulsifiers thiab ntau dua. Raws li cov qauv thoob ntiaj teb, txhua qhov ntxiv tau muab tus lej tshwj xeeb raws li tsab ntawv "E". Tsis yog txhua yam tshuaj ntxiv uas raug txwv hauv Tebchaws Europe lossis lub ntiaj teb yog txwv rau peb. Yog li ntawd, koj yuav tsum ceev faj txog kev xaiv zaub mov.

Thiab rau qhov ntom, ntxiv…

Cia peb nyob ntawm cov khoom xws li dextrin, abbreviated li E1400. Qhov no yog ib qho khoom noj khoom haus ntxiv rau hauv chav kawm ntawm thickeners. Yog hais tias peb xav txog dab tsi dextrin yog los ntawm cov tshuaj pom, nws yog ib qho hnyav molecular carbohydrate tsim thaum lub sij hawm hydrolysis ntawm dextrose los yog glycogen. Los yog nws tau los ntawm kev kho cua sov ntawm pob kws los yog nplej hmoov nplej.

Vim li ntawd, cov hmoov nplej ntawm cov xim daj, xim av lossis xim dawb yog synthesized.

Properties ntawm dextrin

Cia peb nyob ntawm cov khoom ntawm cov khoom no:

  1. Highly soluble dextrin tuaj yeem tsim cov tshuaj tsis muaj kuab lom.
  2. Muaj peev xwm tshem tawm radionuclides (cov tshuaj phem tsis zoo) los ntawm tib neeg lub cev.
  3. Kev nyab xeeb. Nws muaj cov chav kawm tsis tshua muaj kev phom sij thiab tsis muaj kev phom sij rau lub cev, vim nws yog cov khoom lag luam starch.
  4. Nyob zoo. Ua pov thawjCov txiaj ntsig zoo ntawm kev siv dextrin vim nws txoj kev zom zaub mov. Qee zaum nws tuaj yeem siv los ua cov tshuaj sib cais raws li qhov chaw ntawm fiber ntau.
  5. Ntau yam kev thov. Paub tias dextrin yog dab tsi, cov tshuaj no tau siv dav tsis yog hauv kev lag luam khoom noj xwb. Nws yog siv hauv kev luam ntawv, textile, foundry, iav ntau lawm vim nws cov khoom nplaum zoo heev.

Type of dextrin

Muaj ntau qhov kev faib tawm ntawm cov khoom no. Yuav kom nkag siab zoo dua qhov dextrin yog dab tsi, cia peb saib cov hom tseem ceeb.

Kev faib los ntawm txoj kev tsim khoom (catalysts tau qhia hauv cov kab tuav):

  • acidic (acid);
  • ntsev (ntsev ntawm cov kua qaub muaj zog thiab tsis muaj zog);
  • alum (aluminium-potassium alum);
  • Alkaline (alkali).

Kev faib tawm xim:

  • daj - tsim los ntawm cua sov qhuav hmoov nplej;
  • dawb - tau los ntawm kev faib cov hmoov txhuv nplej siab;
Dextrin xim
Dextrin xim

Sib faib los ntawm hom raw khoom:

  • nqaij;
  • pob kws dextrin.

Tsev tsim khoom

Nplej dextrin yog tsim nyob rau hauv ntau yam tib yam li pob kws dextrin. Qhov txawv yog dab tsi? Qhov txawv yog tias pob kws hmoov txhuv nplej siab yog cov hmoov txhuv nplej siab uas muaj cov khoom siv raw, thiab cov hmoov nplej tseem yuav tsum tau ua hauv av rau lub xeev zoo li no. Thiab qhov ntawd tsis yog tag nrho. Soluble nplej dextrin sib tov sai dua thaum lub sij hawm tsim khoom dua pob kws dextrin. Lawv kuj txawv hauvqhov concentration ntawm cov piam thaj dawb hauv cov zaub mov npaj.

Lub hauv paus ntawm kev siv tshuab yog dab tsi? Cov hmoov txhuv nplej siab qhuav (los yog hmoov nplej tau los ntawm kev sib tsoo nplej) yog ntxiv nrog rau kev npaj enzyme qhuav "Amylosubtilin" thiab cov khoom sib tov no yog pub rau lub disintegrator, cov hniav tuaj yeem tig ntawm qhov ceev ntawm 3000 rpm. Thaum tau txais ib homogeneous loj, dej ntxiv rau nws. Tom ntej no, muaj pes tsawg leeg yog rhuab mus rau 80 - 85 ° C (thaum tas li thiab intensively nplawm). Qhov no yog ua raws li los ntawm qhov tshwm sim ntawm cov tshuaj rau 15 feeb. Tom qab ntawd nws yog boiled rau 5 feeb thiab txias.

Cov khoom lag luam tuaj yeem muab tso rau hauv lub xeev cov hmoov txhuv nplej siab ntawm cov khoom xyaw uas xav tau kom yooj yim siv los ntawm cov neeg siv kawg (bakers, confectioners, thiab lwm yam)

E1400 - daim ntawv thov kev lag luam zaub mov

Dextrin yog dab tsi, dab tsi tshwm sim thiab nws tau txais li cas, peb tshuaj xyuas.

Nyob hauv cov zaub mov twg thiab nws muab dab tsi?

Dawb dextrin yog siv rau hauv cov khoom ci ci, yog ib feem ntawm cov khoom noj sib xyaw, txheej, glazes. E1400 txhim kho cov khoom ntawm cov hmoov nplej, ua rau nws yog ib qho khoom noj khoom haus tsis tseem ceeb hauv kev lag luam bakery: lub khob cij golden crispy crust thiab lub txee lub neej ntev ntawm qhob cij.

Toffee, caramel thiab lwm yam khoom ntawm kev lag luam confectionery tsis tuaj yeem ua yam tsis muaj dextrin. Koj tuaj yeem nrhiav tau cov khoom noj khoom haus no txawm nyob rau hauv cov khoom noj me nyuam mos thiab cov khoom sib tov, hauv cawv thiab txawm npias. Nws yog ntxiv vim tias dextrin muaj cov tshuaj nyob rau hauv muaj pes tsawg leeg uas ua raufermentation.

Nws tseem ntxiv rau cov cheese thiab tsev cheese, cov ntses hauv kaus poom, kua zaub thiab kua ntses, marmalade, yogurt, zom cov pos hniav.

Tsis yog txhua tus dextrins muaj kev nyab xeeb li E1400. Tsis yog txhua yam khoom noj ntxiv uas pib nrog tsab ntawv "E" yog qhov tsis zoo. Yog li ntawd, nws tseem ceeb heev kom nkag siab txog qhov teeb meem no. Koj tau kawm tias dextrin E1400 yog dab tsi. Thiab tam sim no koj tsis tuaj yeem ntshai mus yuav ib yam khoom uas nws tau qhia.
