Agar hmoov yog ib hom alginate muab rho tawm los ntawm zaub qhwv thiab lwm cov nroj tsuag liab algae. Nws muaj keeb kwm ntau tshaj 300 xyoo hauv Suav teb thiab Nyiv. Vim tias nws cov khoom tshwj xeeb gel, nws tau siv dav hauv cov khoom noj, tshuaj, tshuaj, textiles, kev tiv thaiv hauv tebchaws, kev tshawb fawb lom neeg thiab lwm yam kev lag luam, thiab yog lub npe hu ua "novel East Asian khoom".
Agar - agar yog dab tsi?
Agar - agar yog ib yam khoom muab rho tawm los ntawm liab algae. Nws yog qhov tseeb ntawm cov khoom uas tsim cov qauv cellular hauv cov nroj tsuag no. Thaum muab rho tawm, koj tau txais cov hmoov zoo uas tsim cov gelatinous kev ntxhib los mos thaum sib cuag nrog cov kua thiab rhuab.
Nws yooj yim pom vim li cas cov cuab yeej no muaj ntau yam siv los hloov cov khoom noj khoom haus, tab sis agar muaj ntau dua li qhov ntawd.
Hais agar – agar hloov txoj kev uas peb pom zaub mov yuav yog ib tug understatement; nws yog ib tug qhabnias kiv puag ncig nrog unlimited siv nyob rau hauv thiab tawm ntawm cov zaub mov kev lag luam.
Nyiv yog qhov chaw algae tau tshawb pom, thiab nws tseem yog ib qho tseem ceeb ntawm agar tsim, tab sis tam sim no koj tuaj yeem pom agar - agar nyob txhua qhov chaw hauv ntiaj teb.
Agar thiab carrageenan yog cov extract ntawm seaweed nrog ntau daim ntawv thov
Agar muaj agarose thiab agar pectin. Agarose, raws li tus neeg sawv cev gelling, yog ib qho nonionic polysaccharide tsis muaj sulfate (ntsev), uas yog ib feem ntawm cov gel. Nws cov macromolecular saw txuas yog sib txuas los ntawm 1,3 glycosidic bonds β- D-pyranosyl galactose residues thiab 3,6- α- L-pyranosyl galactose residue. Agar pectin yog ib feem uas tsis yog gel, ib qho nyuaj polysaccharide nrog sulfate (ntsev), glucuronic acid thiab pyruvic aldehyde, uas kuj yog ib feem uas tau sim muab tshem tawm hauv kev lag luam extraction. Nyob rau hauv kev lag luam, cov xim ntawm agar ranges ntawm dawb mus rau daj me ntsis, nrog ib tug glial rhiab heev, tsis muaj tsw los yog me ntsis cov yam ntxwv tsw. Agar yog insoluble nyob rau hauv dej txias, yooj yim soluble nyob rau hauv boiling dej, thiab maj mam soluble nyob rau hauv dej kub.
Raws li rau lub hom phiaj ntawm agar, thawj zaug, agar yog cov khoom noj tsis muaj zaub mov, uas txhais tau hais tias txawm tias cov kab mob tsis tuaj yeem decompose nws (txawm tias agar belongs rau qab zib). Yog li ntawd, nws feem ntau yog siv los ua cov kab lis kev cai lom neeg lossis qee cov neeg nqa tshuaj. Tsis tas li ntawd, nws yog dav siv nyob rau hauv kev lag luam khoom noj khoom haus raws li ib tug thickener thiab coagulant. Agar melts ntawm ib ncig ntawm 90 degrees thiab solidifies ntawm ib ncig ntawm 40 degrees. Nws kuj tau ntxiv rau feem ntau noj jelly thiab jelly, ua rau nws tsis muaj mob. Cov tshuaj tua kab mob, emulsifiers, stabilizers, thiab cov tshuaj tua kab mob kuj tseem siv tau. Nws yog dav siv los tsim cov txiv kab ntxwv granular thiab ntau yam dej qab zib, jellies, ice cream, ncuav, khoom qab zib, cov kaus poom, nqaij cov khoom, Babao Congee, tremella thiab noog lub zes, kua zaub thiab zaub mov txias.
Carrageenan yog tsim los ntawm polysaccharide sulfate ntsev tsim los ntawm carrageenan, galactose thiab lub cev qhuav dej galactose, thiab 3.6 dehydrated galactose linear saw polymer. Cov hmoov carrageenan ruaj khov thiab yuav tsis raug hydrolysis txawm tias thaum cua sov. Carrageenan muaj cov kua mis zoo cov tshuaj tiv thaiv muaj peev xwm, uas tuaj yeem tiv thaiv qhov tshwm sim ntawm whey sib cais tom qab ntxiv CMC. Lub hom phiaj ntawm ham sausage minced nqaij cov khoom: Tom qab siv cov khoom no, nws tuaj yeem ua rau cov khoom elastic, hlais zoo, nrog rau nruab nrab toughness thiab crispness, thiab kev sib tw, du thiab refreshing. Daim ntawv thov hauv cov khoom noj khoom haus txias: Carrageenan muaj cov kua mis zoo cov tshuaj tiv thaiv, uas tuaj yeem tiv thaiv kev xav ntawm whey sib cais vim qhov sib ntxiv ntawm CMC. Daim ntawv thov hauv cov khoom noj gummy: Carrageenan gummy muaj cov pob tshab zoo, ci, zoo ib yam, xim du, tsis muaj viscosity, thiab crispy saj. Daim ntawv thov hauv cov khoom siv mis nyuj: Carrageenan tuaj yeem ua rau mis nyuj coagulate thiab tsim. Nws plays lub luag hauj lwm ncua kev kawm ntawv thiab stabilization hauv cocoa mis nyuj, cocoa malt extract, thiab cocoa khoom qab zib paste. Nyob rau hauv yogurt, mos cheese, thiab qab zib, ib tug milky sib tov yuav stabilized kom induce tsim gelation. Siv hauv Baijiu thiab npias: nws tuaj yeem siv los ua tus neeg saib xyuas kom meej lossis ua npuas dej stabilizer. Siv rau hauv cov khoom siv fiber ntau thiab cov nqaij dag: Carrageenan thiab sodium alginate tau ntxiv rau hauv cov txheej txheem muaj, yog li cov protein tsis tas yuav ua rau kev laus. Protein tov nrog tsawg concentration los yog tsis muaj purification kuj yuav siv tau rau spinning, thiab nws kuj yuav txhim kho lub zog thiab dej nqus ntawm spinning. Thaum cov khoom siv fiber ntau siv los tsim cov nqaij tawv, carrageenan kuj tseem siv tau los ua cov nplaum.
