Ngokuthuthuka kwamazinga okuphila kwabantu, izidingo zabathengi zokudla azigcini nje kuphela ngenani lokudla okunempilo, kodwa futhi zidinga ukudla ukuze kube nekhwalithi ekwanelisayo ezicini zemizwa njengokubukeka kwezimpawu zokubukeka njengokubukeka, ukubukeka, ubuhlakani, okusha okusha, njll.

Ama-emulsifiers, njengezengezo zokudla zokulungisa isimo, adlale indima ebalulekile embonini yokudla. Ake sibheke indlela yokusebenza kwe-EmpulSifers!

Umusi

I-emulsion ejwayelekile ekudleni iqukethe amanzi noma ikhambi lamanzi, okubhekiselwa kuyo njengesigaba se-hydrophilic; Isigaba esinye isigaba yisigaba esiphilayo esingabonakali ngamanzi, esaziwa nangokuthi isigaba se-lipophilic. Iziphuzo ezimbili ezingenakuqhathaniswa, njengamanzi namafutha, kungadala izinhlobo ezimbili zama-emulsion lapho kuxutshwe, okungukuthi amanzi emafutheni (o / w) ama-emulsions (W / O) ama-emulsions.

Emanzini e-emulsion kawoyela, uwoyela uhlakazeka njengamaconsi amancane emanzini, ngamaconsi kawoyela njengesigaba sokusabalalisa kanye namanzi njengendlela ehlakazayo. Isibonelo, ubisi lwenkomo luyi-O / W emulsion; Emanzini ema-emulsion kawoyela, okuphambene kuyiqiniso. Amanzi ahlakazeka njengamaconsi amancane emafutheni, ngamanzi njengesigaba sokuhlakazeka kanye namafutha njengendlela yokusabalalisa. Isibonelo, ibhotela lokufakelwa luhlobo lwe-W / O Emulsion.

Indlela yokusebenza kwama-emulsifiers

Ama-emulsifiers okudla, owaziwa nangokuthi ama-surfactants, yizinto eziguqula uketshezi olungabonakali zibe yizigaba ezihlakazekile (ama-emulsions). Uma kungezwe ekudleni, zinganciphisa kakhulu ukungezwani phakathi kwamafutha namanzi, okuvumela amafutha angenasici (izinto ze-hydrophobic) namanzi (izinto ze-hydrophilic) ukwenza izithasiselo ezinzile njengezengezo zokudla.

Ngakolunye uhlangothi, ama-emulsifiers akha ungqimba lwe-molecular oluncanyana esigabeni esiphikisayo, ukunciphisa amandla wamahhala wohlelo lonke nokwakha indawo entsha. Ama-molecule e-emulsifier anamaqembu asebenzayo asebenza nge-hydrophilic ne-oleophic, angenza ama-adderb esigameko se-oyela namanzi, akha isendlalelo se-molecular anciphise futhi anciphise ukungezwani kwe-molecular phakathi kwezigaba ezimbili. Okusho ukuthi ingxenye ye-olekyuli yamafutha kanye ne-emulsifier isohlangothi olulodwa, kanye nengxenye ye-hydrophilic ye-molecule yamanzi kanye ne-emulsifier kungaphesheya. Lokhu ukuxhumana phakathi kwalaba bobabili kubangela ushintsho ekuxabaneni kwezingcaci;

Ngakolunye uhlangothi, ngokwakhiwa ungqimba we-adsorption oluvikelayo ebusweni be-Droplet, ufaka amaconsi ngokuqina okuqinile kwendawo. Ama-emulsifiers amaningi angezwa, kukhuphule ukwehla kwezingxabano zokungezwani. Lokhu kuvumela izinto ezingekho emthethweni ezixutshwe ngokufana, zakha uhlelo oluhlakazekile oluguqula isimo sokuqala somzimba, ngaleyo ndlela sithuthukise ukwakheka kwangaphakathi kokudla nokwenza ngcono ikhwalithi yayo.
Inani le-hydrophilic ne-oleophilic eliquilibrium

Ngokuvamile, ama-emulsifers anefomu elinamandla le-hydrophility form Amafutha / ama-emulsions wamanzi, ngenkathi ama-emulsifiers ane-hydrophility eqinile yamanzi amanzi / amafutha. Ukukhombisa ibhalansi ye-hydrophilic ne-lipophilic yama-emulsifiers, inani le-HLB (i-hydrophilic lipophilic ibhalansi yenani) livame ukusetshenziswa, nenani le-HLB lisetshenziselwa ukumela i-hydrophiciers yama-emulsifiers. Kunezindlela zokubala ezahlukahlukene zenani le-HLB,

Umehluko ifomula: HLB = Hydrophility of Hydrophilic Group - Hydrophobicity of Lipophilic Group

Ifomula ye-Ratio: HLB = Hydrophilicity of hydrophilic group / hydrophophobicity yeqembu le-oleophilic

Inani le-HLB le-emulsifier ngayinye linganqunywa ngezindlela zokuhlola. Nge-emulsifiers enama-lipophilicity ayi-100%, i-HLB yabo ingu-0 (amelwe yi-paraffin wax), futhi kulabo abane-100% hydrophilicity, ihlukaniswe ngama-20 (amelwe yizingxenye ezingama-20 ezilinganayo ukukhombisa amandla e-hydrophicity yabo ne-oleophility. Inani elikhulu le-HLB, elinamandla i-hydrophicility, futhi lincane inani le-HLB, liqine i-oleophicity.

Iningi le-emulsifiers edliwayo yi-emulsifiers e-nonic eqinile enamanani we-HLB asukela ku-0 kuye ku-20. Amanani ahlukile we-HLB kanye nezindawo ezihlobene nama-emulsifiers angewona ama-ionic aboniswa etafuleni; Inani le-HLB le-Ionic Surfactants lingu-0- 40. Ngakho-ke, ama-emulsifiers anamanani we-HLB <10 ambalwa kakhulu ama-lipophilic, kanti ama-emulsifiers anamagugu we-HLB ≥ 10 anezici ze-hydrophilic.

Ngama-emulsifiers ahlanganisiwe, amanani awo we-HLB anezakhiwo ezingezansi. Ngakho-ke, lapho ama-emulsifiers amabili noma ngaphezulu axutshwe futhi asetshenziswa, inani le-HLB le-emulsifier elixubile lingabalwa ngokususelwa kwingxenye enkulu ye-emulsifier ngayinye yokwakheka kwayo:

I-HLBA, B = Hlba · a% + hlbb · B%

Efomula,

I-HLBA, B yinani le-HLB le-emulsifier a, B lixube ndawonye;

I-HLBA ne-HLBB ngamanani we-HLB ama-emulsifiers a no-b, ngokulandelana;

I-% ne-B% okuqukethwe ngamaphesenti ka-emulsifier ahlanganisiwe, ngokulandelana (le formula isebenza kuphela kuma-emulsifers angewona ama-ionic).
Izindlela zokulungiselela kanye nokuthonya izici zama-emulsifiers

Kunezindlela ezine zokulungiselela ama-emulsifers, okuyindlela ye-gel eyomile, indlela enamanzi e-wet gel, indlela yokuxubana yamanzi kawoyela, nendlela yokwenza.

Indlela ye-Gry GEL, efaka ukwengeza amanzi esigabeni samafutha aqukethe ama-emulsifiers. Ngesikhathi sokulungiselela, i-awwber powder (emulsifier) ​​ihlanganiswe ngokulinganayo ngamafutha, kufakwa inani elithile, umhlabathi futhi kuncibilikiswa ku-colostrum, bese kuvinjwana ngamanzi ngemali ephelele.

Indlela ye-Wet GEL, ehilela ukwengeza uwoyela esigabeni samanzi aqukethe ama-emulsifers. Ngesikhathi sokulungiselela, ijeli (emulsifier) ​​ichithwa okokuqala emanzini ukuze kwakhiwe i-slurry njengesigaba samanzi. Ngemuva kwalokho, isigaba samafutha sengezwe esigabeni samanzi ezigabeni, emhlabathini eColostrum, namanzi angezwa ngenani eliphelele.

Hlanganisa izigaba zamafutha nezinziselo zamanzi bese uzingeza ku-emulsifier, ukuxubana inani elithile lamafutha namanzi. Gaya gum yesi-Arabhu ube odaka, bese ugaye ngokushesha ingxube yamanzi kawoyela e-colostrum, unciphise ngamanzi.

Ukulungiswa kwama-emulsifiers ikakhulukazi kubandakanya ukukhipha iziphuzo ezimbili, futhi ikhwalithi ye-emulsation inomthelela omkhulu kwikhwalithi ye-emulsion.

Izici ezithinta ukucaciswa ngokuyinhloko zifaka ukungezwani kwezingcweti, ukubonakala kanye nokushisa, isikhathi se-emulsation, kanye nenani le-emulsifier elisetshenzisiwe. Ama-emulsifiers anganciphisa kakhulu ukungezwani kwezokuxhumana ngokuvamile kukhethwe; Amazinga okushisa afanele kakhulu e-emulsation ama-emulsifiers acishe abe ngu-70 ℃. Uma kusetshenziswa ama-surfic angasebenzi njengama-emulsifiers, izinga lokushisa le-emulsation akufanele lidlule izinga lokushisa eliphakeme kakhulu; Ama-emulsifiers amaningi asetshenziswa, kuzinze ngokwengeziwe ama-emulsion akhiwa.
