Emulsion

Emulsion e tloaelehileng lijong e na le metsi kapa tharollo e nang le metsi, e kopanetsoeng e bitsoang hydrophilic phase; Karolo e 'ngoe ke karolo ea tlhaho e ke keng ea kopanngoa le metsi, e tsejoang hape e le karolo ea lipophilic. Mekelikeli e 'meli e sa tsitsang, joalo ka metsi le oli, e ka etsa mefuta e 'meli ea li-emulsion ha e tsoakoa, e leng metsi ka har'a oli (O/W) le metsi ka har'a oli (W/O) emulsion.

Ka metsing a emulsion ea oli, oli e qhalakanngoa joalo ka marotholi a manyane ka metsing, ka marotholi a oli e le mohato oa ho hasana le metsi joalo ka mokhoa oa ho hasanya. Mohlala, lebese la khomo ke emulsion ea O/W; Ka metsing ka li-emulsions tsa oli, se fapaneng ke 'nete. Metsi a qhalakanngoa joaloka marotholi a manyenyane ka har'a oli, metsi e le karolo ea ho hasana le oli e le mokhoa oa ho hasanya. Ka mohlala, botoro ea maiketsetso ke mofuta oa emulsion ea W / O.

Mokhoa oa ts'ebetso oa li-emulsifiers

Li-emulsifiers tsa lijo, tse tsejoang hape e le li-surfactants, ke lintho tse fetolang metsi a sa khoneheng hore e be mekhahlelo e arohaneng ka mokhoa o ts'oanang (emulsions). Ha li eketsoa lijong, li ka fokotsa haholo tsitsipano ea sefahleho pakeng tsa oli le metsi, ho lumella oli e sa tsitsang (lintho tsa hydrophobic) le metsi (lintho tsa hydrophilic) ho theha emulsions e tsitsitseng e le li-additives tsa lijo.

Ka lehlakoreng le leng, li-emulsifiers li etsa lera le tšesaane la molek'hule holim'a libaka tse hlabang ka bobeli, ho fokotsa matla a mahala a holim'a tsamaiso eohle le ho etsa li-interfaces tse ncha. Limolek'hule tsa emulsifier li na le lihlopha tse sebetsang tsa hydrophilic le oleophilic, tse ka khahlang holim'a karolo e nyenyefatsang ea oli le metsi, tsa etsa lera le lesesaane la limolek'hule le ho fokotsa tsitsipano lipakeng tsa mekhahlelo ena e 'meli. Ke hore, karolo ea oleophilic ea molek'hule ea oli le emulsifier e ka lehlakoreng le leng, 'me karolo ea hydrophilic ea molek'hule ea metsi le emulsifier e ka lehlakoreng le leng. Tšebelisano ena pakeng tsa tse peli e baka phetoho ea tsitsipano pakeng tsa sefahleho;

Ka lehlakoreng le leng, ka ho etsa lera le sireletsang la adsorption holim'a lerotholi, le fa lerotholi ka botsitso bo matla ba sebaka. Ha li-emulsifiers li ntse li eketsoa, ​​​​ho fokotseha ho hoholo ha tsitsipano ea sefahleho. Sena se lumella lintho tseo pele li neng li sa khone ho kopanngoa ka mokhoa o ts'oanang, ho theha tsamaiso ea homogeneous e qhalakantsoeng e fetolang boemo ba pele ba 'mele, kahoo e ntlafatsa sebopeho sa ka hare sa lijo le ho ntlafatsa boleng ba eona.
Hydrophilic le oleophilic equilibrium value

Ka kakaretso, li-emulsifiers tse nang le hydrophilicity e matla li etsa li-emulsion tsa oli/metsi, ha li-emulsifiers tse nang le hydrophilicity e matla li etsa li-emulsion tsa metsi/oli. Ho bontša tekanyo ea hydrophilic le lipophilic ea li-emulsifiers, boleng ba HLB (hydrophilic lipophilic balance value) hangata bo sebelisoa, 'me boleng ba HLB bo sebelisetsoa ho emela hydrophilicity ea emulsifiers. Ho na le mekhoa e fapaneng ea lipalo bakeng sa boleng ba HLB,

Foromo e fapaneng: HLB = hydrophilicity ea sehlopha sa hydrophilic - hydrophobicity ea sehlopha sa lipophilic

Karo-karolelano ea foromo: HLB=hydrophilicity ea sehlopha sa hydrophilic/hydrophobicity ea sehlopha sa oleophilic

Boleng ba HLB ba emulsifier ka 'ngoe bo ka khethoa ka mekhoa ea liteko. Bakeng sa li-emulsifiers tse nang le 100% lipophilicity, HLB ea bona ke 0 (e emetsoeng ke boka ba parafine), le bakeng sa ba nang le 100% hydrophilicity, HLB ea bona ke 20 (e emetsoeng ke potassium oleate), e arotsoe ka likarolo tse 20 tse lekanang ho bontša matla a hydrophilicity ea bona le oleophilicity. Ha boleng ba HLB bo le boholo, bo matla ba hydrophilicity, 'me boleng ba HLB bo nyenyane, bo matla ba oleophilicity.

Bongata ba li-emulsifiers tse jeoang ke li-surfactants tse seng tsa ionic tse nang le boleng ba HLB ho tloha ho 0 ho ea ho 20. Litekanyetso tse fapaneng tsa HLB le thepa e amanang le li-emulsifiers tse seng tsa ionic li bontšitsoe tafoleng; Boleng ba HLB ba li-ionic surfactants ke 0-40. Ka hona, li-emulsifiers tse nang le boleng ba HLB<10 haholo-holo lipophilic, ha li-emulsifiers tse nang le litekanyetso tsa HLB ≥10 li na le litšobotsi tsa hydrophilic.

Bakeng sa li-emulsifiers tse tsoakiloeng, boleng ba tsona ba HLB bo na le thepa ea tlatsetso. Ka hona, ha li-emulsifier tse peli kapa ho feta li tsoakoa 'me li sebelisoa, boleng ba HLB ba emulsifier e tsoakiloeng bo ka baloa ho ipapisitsoe le karolo ea boima ba emulsifier ka 'ngoe sebopehong sa eona:

HLBa,b =HLBa·A%+HLBb·B%

Ka foromo,

HLBa, b ke boleng ba HLB ba emulsifier a, b e kopantsoeng hammoho;

HLBa le HLBb ke boleng ba HLB ba li-emulsifiers a le b, ka ho latellana;

A% le B% ke liphesente tsa likahare tsa a le b ho emulsifier e tsoakiloeng, ka ho latellana (formula ena e sebetsa feela ho li-emulsifiers tse seng tsa ionic).
Mekhoa ea ho itokisa le lintlha tse susumetsang tsa li-emulsifiers

Ho na le mekhoa e mene ea ho lokisa li-emulsifiers, e leng mokhoa oa gel o omileng, mokhoa oa gel o metsi, mokhoa oa ho kopanya karolo ea oli le metsi, le mokhoa oa mochini.

Mokhoa o omileng oa gel, o kenyelletsang ho eketsa metsi mokhahlelong oa oli o nang le li-emulsifiers. Nakong ea ho itokisa, phofo ea rabara (emulsifier) ​​e qala ho tsoakoa ka ho lekana le oli, metsi a mangata a eketsoa, ​​a fatše ebe a kenngoa ka har'a colostrum, ebe e hlapolloa ka metsi ho fihlela tekanyo e feletseng.

Mokhoa oa gel o metsi, o kenyelletsang ho eketsa oli mokhahlelong oa metsi o nang le li-emulsifiers. Nakong ea ho lokisoa, gel (emulsifier) ​​e qala ho qhibiliha ka metsing ho etsa slurry e le karolo ea metsi. Ka mor'a moo, karolo ea oli e kenngoa karolong ea metsi ka mekhahlelo, e siloa ka colostrum, 'me metsi a eketsoa ka tekanyo e feletseng.

Kopanya likarolo tsa oli le metsi 'me u li kenye ho emulsifier, kopanya palo e itseng ea oli le metsi. Sila chepisi ea Searabia ka seretseng, ebe ka potlako u sila motsoako oa oli-metsi ka colostrum, 'me u hlapolle ka metsi.

Ho lokisoa ha li-emulsifiers haholo-holo ho kenyelletsa ho kenya metsi a mabeli, 'me boleng ba emulsification bo na le tšusumetso e kholo ho boleng ba emulsion.

Lintho tse amang emulsification haholo-holo li kenyelletsa tsitsipano ea sefahleho, viscosity le mocheso, nako ea emulsification, le palo ea emulsifier e sebelisoang. Li-emulsifiers tse ka fokotsang tsitsipano ea sefahleho haholo hangata li khethoa; Thempereichara e loketseng ka ho fetesisa bakeng sa li-emulsifiers e ka ba 70 ℃. Haeba li-surfactants tse seng tsa ionic li sebelisoa e le li-emulsifiers, mocheso oa emulsification ha oa lokela ho feta mocheso oa bona o phahameng; Ha ho sebelisoa li-emulsifiers tse ngata, ho ba le emulsion e tsitsitseng haholoanyane.
