Qhov txawv ntawm agar thiab alginate yog agar yog tau los ntawm liab algae, whereas alginate yog tau los ntawm xim av algae.
Agar thiab alginate yog cov khoom uas peb tuaj yeem siv sib hloov hauv lawv daim ntawv thov vim lawv muaj qhov zoo sib xws thiab ua haujlwm. Txawm li cas los xij, lawv lub hauv paus pib txawv ntawm ib leeg.
Agar yog dab tsi?
Agar yog cov khoom zoo li jelly ua los ntawm cov algae liab. Muaj ob yam tseem ceeb ntawm agar: linear polysaccharide agarose thiab heterogeneous sib tov ntawm me me molecules hu ua agaropectin. Cov khoom no tuaj yeem tsim cov qauv txhawb nqa ntawm cov phab ntsa ntawm tes ntawm qee hom algae. Txawm li cas los xij, agar tso tawm ntawm phab ntsa ntawm tes thaum boiling. Hom algae uas muaj agar yog hu ua agarophytes. Lawv zwm rau Rhodophyta (liab algae) phylum.

Agar muaj txiaj ntsig zoo li cov khoom noj qab zib hauv thaj av Esxias, tab sis nws feem ntau siv los ua cov khoom siv hauv qab uas muaj kab lis kev cai rau kev ua haujlwm microbiological. Nws kuj tseem muaj txiaj ntsig zoo li laxative, raws li kev noj qab haus huv, ua tus neeg tsis noj nqaij hloov rau gelatin, ua cov kua txiv hmab txiv ntoo, ua cov khoom xyaw hauv cov txiv hmab txiv ntoo khaws cia, ice cream, thiab lwm yam khoom qab zib, thiab ua tus neeg sawv cev qhia meej hauv brewing. Nws kuj tseem muaj txiaj ntsig qee zaus rau kev ntsuas cov ntawv thiab cov ntaub.
Cov tshuaj tiv thaiv uas ua rau cov xwm txheej zoo li jelly hauv agar yog cov polysaccharide unbranched, uas tau los ntawm cov phab ntsa ntawm tes ntawm qee hom liab algae. Txawm li cas los xij, rau cov ntawv thov kev lag luam, agar feem ntau tau los ntawm ogonori.
Ntawm ob lub ntsiab lus ntawm agar, agarose thiab agaropectin, agarose tsim txog li 70% ntawm qhov sib tov. Agarose yog cov khoom siv polymer (ib hom kab hluav taws xob) uas muaj qhov rov ua dua ntawm agarobiose. Agarobiose yog ib qho disaccharide ua los ntawm D-galactose thiab 3, 6-anhydro-L-galactopyranose. Ntawm qhov tod tes, agaropectin muaj alternating units ntawm D-galactose thiab L-galactose uas hloov nrog acidic sab pawg.
Alginate yog dab tsi?
Alginate yog lub hauv paus conjugate ntawm alginic acid. Alginic acid yog polysaccharide uas tshwm sim nyob rau hauv lub cell phab ntsa ntawm xim av algae. Cov tshuaj no yog hydrophilic, thiab nws tuaj yeem tsim cov pos hniav thaum hydrating. Nws tuaj yeem tsim cov ntsev xws li sodium alginate thiab calcium alginate nrog hlau ions. Cov tsos ntawm cov khoom no tuaj yeem muaj xws li dawb mus rau daj-xim av.

Lub alginate peb paub tam sim no yog cov qauv tsim uas muaj txiaj ntsig zoo los hloov cov agar thaum agar tsis tshua muaj tshwm sim thaum Tsov Rog Ntiaj Teb Zaum II. Feem ntau, cov khoom siv no feem ntau siv ntau dua li agar, feem ntau hauv kev kho hniav tam sim no vim qhov yooj yim ntawm kev siv.
Alginate yog kev lag luam muaj nyob rau hauv cov ntim ntau thiab ua cov pob khoom hnyav ua ntej rau kev siv tus kheej. Feem ntau, peb tau muab ib lub tog raj kheej yas nrog rau daim ntawv no alginate muag rau kev ntsuas dej. Peb tuaj yeem sib tov 16 grams ntawm cov hmoov no nrog 38 mL dej kom tau txais cov khoom kawg uas xav tau. Cov khoom xyaw ntawm cov khoom lag luam alginate muaj xws li soluble alginates xws li sodium alginate, zinc oxide, calcium alginate, potassium titanium fluoride, diatomaceous ntiaj teb (cov khoom muab tub lim), sodium phosphate, colouring agents thiab flavoring agents.
Feem ntau, alginate muaj qhov qab ntxiag saj thiab tsw. Qee zaum nws kuj muaj qee qhov tsw, suav nrog strawberry, txiv kab ntxwv, mint thiab vanilla tsw. Txawm li cas los xij, alginate muaj lub zog tsim kua muag tsis zoo thiab feem ntau cov yam ntxwv uas cuam tshuam rau lub zog no suav nrog cov dej siv, sib xyaw lub sijhawm, lub sijhawm tshem tawm kev xav, thiab lwm yam.
Dab tsi zoo sib xws ntawm Agar thiab Alginate?
- Agar thiab alginate tshwm li jellies thaum hydrated.
- Lawv nyob hauv "sol" xeev hauv lawv daim ntawv thov.
- Ob yam khoom yog tau los ntawm seaweed.
- Peb tuaj yeem siv alginate hloov pauv rau agar vim tias lawv muaj ntau qhov sib xws.
Qhov txawv ntawm Agar thiab Alginate yog dab tsi?
Agar yog cov khoom zoo li jelly uas ua los ntawm cov algae liab thaum alginate yog lub hauv paus ntawm alginic acid. Qhov sib txawv tseem ceeb ntawm agar thiab alginate yog agar yog tau los ntawm liab algae, whereas alginate yog tau los ntawm xim av algae. Ntxiv mus, hauv kev tsim cov gel, agar tau hloov pauv lub cev thaum alginate tau hloov pauv tshuaj.
Hauv qab no yog cov ntsiab lus ntawm qhov sib txawv ntawm agar thiab alginate hauv daim ntawv tabular.
Summary – Agar vs Alginate
Agar thiab alginate qhia ntau qhov sib xws thiab qhov sib txawv. Qhov sib txawv tseem ceeb ntawm agar thiab alginate yog agar yog tau los ntawm liab algae, whereas alginate yog tau los ntawm xim av algae.
