Fa'amatala：
O fa'atulagaga o mea'ai e aofia aiethers cellulose
Matāgaluega fa'atekinolosi：
O lenei mea fou e fitoitonu i mea'ai o lo'o i ai le cellulose ethers.
Metotia o le talaaga：
Ua leva ona iloa le fa'aaogaina o le cellulose ethers i totonu o mea'ai, aemaise lava mea'ai ua uma ona fa'agasolo, e fa'aleleia atili ai meatotino eseese e pei o le mautu ma le fa'a'aisa ma le fa'asusu, pe fa'aleleia atili ai le malosi i le taimi o gaosiga, fa'agasolo fa'amekanika pe falai. O le talosaga pateni Peretania GB 2 444 020 o lo'o fa'ailoa mai ai ia mea'ai o lo'o aofia ai se nonionic cellulose ether e pei o le methylcellulose, hydroxypropyl cellulose, po'o le hydroxypropyl methylcellulose. O le Methylcellulose ma le hydroxypropyl methylcellulose e iai "meatotino e mafai ona toe fa'afo'isia ai le gelling". Ua fa'amatalaina patino pe a fa'avevela se vaifofo vai o le methylcellulose po'o le hydroxypropyl methylcellulose, o le vaega hydrophobic methoxy o lo'o i totonu o le mole e fa'amamago, ma avea ai ma se gel vai. I le isi itu, pe a fa'amālūlūina le gel e maua mai ai, o vaega hydrophobic methoxy e toe fa'asusuina, ma toe fo'i ai le gel i le vaifofo muamua.
O le Pateni Europa EP I 171 471 ua faʻaalia ai le methylcellulose lea e matua aoga lava i meaʻai mafiafia e pei o fualaau faisua mafiafia, aano o manu, ma pati soya ona o lona malosi faʻateleina o le gel. O le methylcellulose e faʻaleleia atili ai le mausali ma le pipii i meaʻai mafiafia, ma maua ai se lagona lelei mo tagata faʻatau e 'ai le meaʻai ua uma ona faʻagasolo. A faʻafefiloi i le vai malulu (e pei o le 5°C pe maualalo ifo) aʻo leʻi faʻafefiloi pe a uma ona faʻafefiloi ma isi meaʻai o loʻo i totonu o le meaʻai, e oʻo atu le methylcellulose soy i lona gafatia atoatoa e maua ai meaʻai mafiafia ma le mausali ma le pipii lelei.
Peita'i, i nisi tulaga, o le fa'aaogaina o le vai malulu e le talafeagai mo le gaosi o mea'ai. O le mea lea, e mana'omia le tu'uina atu o cellulose ethers e maua ai mea'ai mafiafia e ma'a'a lelei ma pipi'i tusa lava pe fa'afefiloi le cellulose ethers i le vai e tusa ma le vevela o le potu.
O le Hydroxyalkyl methylcellulose e pei o le hydroxypropyl methylcellulose (lea e lauiloa foi lona aoga i mea'ai) ua iloa e maualalo le modulus o le teuina pe a fa'atusatusa i le methylcellulose. O Hydroxyalkyl methylcelluloses e maualalo le modulus o le teuina e le fausia ai ni gel malolosi. E mana'omia ni maualuga le malosi mo gels vaivai (Haque, A; Richardson; Morris, ER, Gidley, MJ ma Caswell, DC i le Carbohydrate Polymers22 (1993) i.175; ma Haque, A ma Morris, ER1nCarbohydrate Polymers22 (1993) i.161).
A fa'aopoopoina hydroxyalkyl methylcelluloses e pei o le hydroxypropyl methylcellulose (lea e maualalo le modulus o le teuina) i tu'ufa'atasiga o mea'ai malo, o lo latou ma'a'a ma le pipi'i e le lava le maualuga mo nisi fa'aoga.
O se fa'amoemoega o lenei mea fou o le tu'uina atu lea o le hydroxyalkyl methylcellulose, aemaise lava le hydroxypropyl methylcellulose, lea e tutusa ma hydroxyalkyl methylcelluloses ua iloa, e pei o le hydroxypropyl methylcellulose. I se fa'atusatusaga, o mea'ai malo e tu'uina atu i le fa'aleleia atili o le malosi ma/po'o le pipii.
O se tasi o sini autū o lenei mea fou o le tuʻuina atu lea o le hydroxyalkyl methylcellulose, aemaise lava le hydroxypropyl methylcellulose, lea e maua ai ni meaʻai mafiafia e lelei le maʻaʻa ma/poʻo le pipii e tusa lava pe faʻavaivaia le hydroxyalkyl methylcellulose i le vai e tusa ma le vevela o le potu.
O le mea e ofo ai, ua iloa aihydroxyalkyl methylcellulose, aemaise lava le hydroxypropyl methylcellulose, e mafai ona fa'aaogaina i le sauniuniga o mea'ai mafiafia. Pe a fa'atusatusa i mea'ai mafiafia ua iloa, o mea'ai mafiafia ua sili atu lo latou ma'a'a ma/po'o le pipi'i.
O se mea e ofo ai fo'i, ua iloa ai o nisi o hydroxyalkyl methylcelluloses, aemaise lava le hydroxypropyl methylcellulose, e lē mana'omia ona fa'afefiloi i le vai malulu e maua ai ni tu'ufa'atasiga o mea'ai malō e lelei le ma'a'a ma/pe pipi'i.
