Alginic acid yog ib qho polysaccharide aldehyde ntuj pom muaj nyob rau hauv cov phab ntsa cell ntawm cov algae xim av xws li kelp thiab kelp. Cov mis tshuaj (C6H8O6) n. Ib qho linear copolymer tsim los ntawm 1,4-bonding ntawm β-D-mannuronic acid (M) thiab α-L-guluronic acid (G), cov ntsiab lus ntawm G thiab M hauv alginate muaj qhov cuam tshuam loj rau cov khoom gelling ntawm cov fibers. Alginate muaj nyob rau hauv cytoplasm thiab ua lub luag haujlwm hauv kev txhawb nqa cov phab ntsa cell. Alginate sib xyaw nrog ntau yam cations hauv dej hiav txwv los tsim ntau yam alginates. Cov extract tau los ntawm seaweed feem ntau yog sodium alginate. Sodium alginate muaj cov yam ntxwv ntawm thickening, suspending, emulsifying, stabilizing, tsim gel, tsim zaj duab xis thiab spinning fiber. Nws muaj kev siv ntev thiab dav hauv cov khoom noj, ua ntawv, tshuaj pleev ib ce thiab lwm yam lag luam, tshwj xeeb tshaj yog nyob rau hauv biomedical engineering teb nyob rau hauv xyoo tas los no.
Kev Siv
Cov roj hmab ua los ntawm alginic acid uas tau los ntawm cov noob seaweed xim av, xws li Macrocystis pyrifera. Cov derivatives yog sodium, ammonium, thiab potassium ates uas sodium ntsev yog feem ntau. Lawv yog siv los muab cov tuab, gelling, thiab khi. Ib qho derivative tsim los rau kev txhim kho acid thiab calcium stability yog propylene glycol ate. Cov s yog soluble nyob rau hauv dej txias thiab tsim cov gels tsis thermomorevertible nyob rau hauv react nrog calcium ions thiab nyob rau hauv acidic mob. Algin yog siv nyob rau hauv ice cream, icings, puddings, khoom qab zib gels, thiab fabricated txiv hmab txiv ntoo.
Cov dej noo rhiab heev
Algin (alginic acid) yog siv rau hauv cov tshuaj pleev ib ce ua ib yam khoom ua kom tuab, ua kom ruaj khov, thiab ua kom gelling. Nws tau los ntawm ntau hom seaweed xim av sib txawv.
Alginic Acid yog cov kua qaub, tsis yaj ntawm algin uas yog cov hmoov dawb mus rau daj uas tau los ntawm cov seaweed xim av, xws li macrocystis pyrifera. Cov derivatives yog soluble thiab suav nrog sodium, potassium, thiab ammonium alginate thiab propylene glycol alginate. Nws yog siv ua cov tshuaj disintegrant thiab ua cov khoom xyaw antacid.
Ntim thiab Xa Khoom
25KG / Nruas los yog raws li cov neeg siv khoom xav tau.
Yog cov khoom siv dav dav thiab tuaj yeem xa los ntawm dej hiav txwv thiab huab cua
Khaws cia thiab khaws cia
Lub neej txee: 24 lub hlis txij li hnub tsim khoom hauv cov ntim khoom tsis tau qhib khaws cia rau hauv qhov chaw txias thiab qhuav kom tsis txhob raug tshav ntuj ncaj qha, dej.
Lub tsev rau khoom muaj cua nkag, ziab kom qhuav kub tsawg, Sib cais ntawm cov tshuaj oxidants, cov kua qaub.
