Lino tsa lebese tse nang le asiti li atile haholo lilemong tsa morao tjena ka lebaka la melemo ea tsona ea bophelo bo botle le tatso e ikhethang. Leha ho le joalo, lino tsena li ka ba phephetso ho tsitsisa, kaha asiti e ka lebeseng e ka etsa hore liprotheine li fetohe 'me li etse li-aggregates, tse lebisang ho sedimentation le karohano. Mokhoa o mong o sebetsang oa ho tsitsisa lino tsa lebese tse nang le asiti ke ka tšebeliso ea carboxymethyl cellulose (CMC), polymer e qhibilihang ka metsing e khonang ho sebelisana le liprotheine le lisebelisoa tse ling ho theha li-suspensions tse tsitsitseng. Sehloohong sena, re tla tšohla mokhoa oa ts'ebetso oa ho tsitsisa lino tse nang le acidified lebese ke CMC.

Sebopeho le Thepa ea CMC

CMC e tsoa ho cellulose, polymer ea tlhaho e fumanehang maboteng a lisele tsa semela. E entsoe ka ho fetola selulose ka lik'hemik'hale ka lihlopha tsa carboxymethyl, tse ntlafatsang ho qhibiliha ha metsi le lisebelisoa tse ling. CMC ke polymer e nang le makala a phahameng haholo e nang le mokokotlo oa ketane e telele le liketane tse ngata tse mahlakoreng tsa lihlopha tsa carboxymethyl. The degree of substitution (DS) ea CMC e bolela palo ea lihlopha tsa carboxymethyl ka yuniti ea selulose, 'me e lekanya tekanyo ea ho qhibiliha le viscosity ea CMC.

Action Mechanism of CMC in Stabilizing Milk Milk Drinks

Keketso ea CMC ho lino tse nang le asiti ea lebese e ka ntlafatsa botsitso ba tsona ka mekhoa e mengata:

1. Electrostatic Repulsion: Lihlopha tsa carboxymethyl ho CMC li qosoa hampe 'me li ka sebelisana le liprotheine tse qosoang hantle le lisebelisoa tse ling lebeseng, ho theha matla a nyonyehang a thibelang liprotheine ho kopana le ho lula. Sena se repulsion electrostatic tsitsa ho fanyeha le ho thibela sedimentation.
2. Hydrophilic Interactions: Mofuta oa hydrophilic oa CMC o o lumella ho sebelisana le limolek'hule tsa metsi le likarolo tse ling tsa hydrophilic ka lebese, ho etsa lera le sireletsang ho pota-potile liprotheine le ho li thibela ho sebelisana.
3. Thibelo ea Steric: Sebopeho sa makala aCMCe ka etsa hore ho be le tšitiso ea steric, ho thibela liprotheine hore li se ke tsa kopana le ho etsa li-aggregates. Liketane tse telele, tse tenyetsehang tsa CMC le tsona li ka phuthela likaroloana tsa protheine, tsa theha tšitiso e li thibelang ho kopana.
4. Viscosity: Keketso ya CMC ho dino tsa lebese tse nang le asiti e ka eketsa viscosity ya tsona, e ka thibelang ho thella ka ho fokotsa lebelo la ho lokisa la dikarolwana. Ho eketseha ha viscosity ho ka boela ha theha ho fanyeha ho tsitsitseng haholoanyane ka ho matlafatsa likamano pakeng tsa CMC le metsoako e meng ea lebese.

Lintlha tse Amang ho Tsitsisoa ha Lino tsa Lebese le Asiti ka CMC

Ho sebetsa ha CMC ho tsitsiseng lino tse nang le acidified lebese ho itšetlehile ka lintlha tse 'maloa, ho kenyelletsa:

1. pH: Ho tsitsa ha dino tsa lebese tse nang le asiti ho susumetswa haholo ke pH. Ka litekanyetso tse tlase tsa pH, liprotheine tse ka lebeseng lia fetoha 'me li etsa li-aggregates habonolo, e leng se etsang hore botsitso bo be thata le ho feta. CMC e ka tsitsisa lino tsa lebese tse nang le asiti ka boleng ba pH bo tlase joalo ka 3.5, empa katleho ea eona ea fokotseha ka boleng bo tlase ba pH.
2. Concentration of CMC: Kemiso ea CMC lebeseng e ama thepa ea eona ea botsitso. Maemo a phahameng a CMC a ka lebisa ho ho eketseha ha viscosity le botsitso bo ntlafalitsoeng, empa ho tsepamisa maikutlo ho phahameng haholo ho ka baka sebopeho le tatso e sa rateheng.
3. Protein Concentration: Motsoako le mofuta oa liprotheine lebeseng li ka ama botsitso ba seno. CMC e sebetsa hantle haholo tabeng ea ho tsitsisa lino tse nang le protheine e fokolang, empa e ka boela ea tsitsisa lino tse nang le liprotheine tse phahameng haeba likaroloana tsa protheine li le nyenyane 'me li arotsoe ka ho lekana.
4. Maemo a Tshebetso: Maemo a ho sebetsa a sebelisetsoang ho hlahisa seno sa lebese se nang le asiti a ka ama botsitso ba sona. Matla a phahameng a ho kuta le mocheso a ka baka protheine denaturation le aggregation, e lebisang ho hloka botsitso. Maemo a ho sebetsa a lokela ho ntlafatsoa ho fokotsa protheine.
