Nekuvandudzwa kwemararamiro evanhu, zvinodiwa nevatengi zvekudya hazvingogumiri pakukosha kwehutano hwakanaka, asi zvinodawo kuti chikafu chive nemhando inogutsa muhunhu hwekunzwa senge chitarisiko, ruvara, kunhuhwirira, kuravira, viscosity, kutsva, nezvimwe.

Emulsifiers, sekuwedzera kwechikafu kwekugadzirisa, inoita basa rakakosha muindasitiri yezvekudya. Ngatitarisei maitiro ekuita emulsifiers!

Emulsion

Iyo yakajairika emulsion mukudya inosanganisira mvura kana aqueous solution, pamwe chete inonzi hydrophilic phase; Iyo imwe nhanho ndeye organic chikamu chisingaenderane nemvura, inozivikanwawo se lipophilic phase. Zvinwiwa zviviri zvisingagoneki, zvakaita semvura nemafuta, zvinogona kuumba marudzi maviri emulsion kana asanganiswa, anoti mvura mumafuta (O/W) uye mvura mumafuta (W/O) emulsions.

Mumvura mumafuta emulsion, mafuta anoparadzirwa semadonhwe madiki mumvura, aine madonhwe emafuta sechikamu chekuparadzira uye mvura senzira yekuparadzira. Somuenzaniso, mukaka wemhou imulsion yeO/W; Mumvura mumafuta emulsions, zvinopesana ndezvechokwadi. Mvura inoparadzirwa semadonhwe madiki mumafuta, iine mvura sechikamu chekuparadzira uye mafuta senzira yekuparadzira. Semuenzaniso, bota rekugadzira rudzi rweW/O emulsion.

Iyo nzira yekuita emulsifiers

Maemulsifiers echikafu, anozivikanwawo sema surfactants, zvinhu zvinoshandura zvinwiwa zvisingagoneki kuita zvikamu zvakaparadzaniswa zvakafanana (emulsions). Kana yawedzerwa kune chikafu, inogona kuderedza zvakanyanya kupindirana kwepakati pakati pemafuta nemvura, zvichibvumira mafuta asingakanganisi (hydrophobic substances) uye mvura (hydrophilic substances) kuumba emulsions yakagadzikana sezvokudya zvinowedzera.

Kune rimwe divi, emulsifiers inoumba yakatetepa molecular layer pane inotenderedza chikamu chinosemesa, ichidzikisa pamusoro mahara simba rehurongwa hwese uye kugadzira mitsva yekusangana. Emulsifier mamorekuru ane hydrophilic uye oleophilic anoshanda mapoka, ayo anogona kushambadza pane anosemesa chikamu chepamusoro pemafuta nemvura, achigadzira yakatetepa molecular layer uye kuderedza kusawirirana kwechiso pakati pezvikamu zviviri izvi. Ndiko kuti, iyo oleophilic chikamu chemafuta molecule uye emulsifier iri kune rumwe rutivi, uye hydrophilic chikamu chemvura molecule uye emulsifier kune rumwe rutivi. Kudyidzana uku pakati pezviviri izvi kunokonzeresa shanduko mukukakavadzana kwemukati;

Kune rumwe rutivi, nekugadzira inodzivirira adsorption layer pamusoro peiyo droplet, inoisa iyo inodonha nekugadzikana kwakasimba kwenzvimbo. Iyo yakawanda emulsifiers inowedzerwa, kunowedzera kuderera kwekubatana kwemukati. Izvi zvinobvumira zvinhu zvaimbova zvisingagoneki kuti zvibatanidzwe zvakaenzana, zvichigadzira homogeneous yakapararira sisitimu inoshandura mamiriro ekutanga emuviri, nekudaro ichivandudza chimiro chemukati chechikafu uye kuwedzera kunaka kwayo.
Hydrophilic uye oleophilic equilibrium kukosha

Kazhinji, emulsifiers ane yakasimba hydrophilicity anoumba emulsion yemafuta / emvura, nepo emulsifiers ane yakasimba hydrophilicity anoumba emulsion yemvura/oiri. Kuratidza hydrophilic uye lipophilic balance ye emulsifiers, HLB kukosha (hydrophilic lipophilic balance value) inowanzoshandiswa, uye HLB kukosha inoshandiswa kumiririra hydrophilicity ye emulsifiers. Kune akasiyana nzira dzekuverenga dzeHLB kukosha,

Musiyano formula: HLB = hydrophilicity ye hydrophilic boka - hydrophobicity ye lipophilic boka

Ratio formula: HLB = hydrophilicity ye hydrophilic boka / hydrophobicity ye oleophilic boka

HLB kukosha kwega yega emulsifier inogona kutariswa nenzira dzekuyedza. Kune emulsifiers ane 100% lipophilicity, HLB yavo 0 (inomiririrwa neparafini wax), uye kune avo vane 100% hydrophilicity, HLB yavo i20 (inomiririrwa ne potassium oleate), yakakamurwa kuita 20 zvikamu zvakaenzana kuratidza simba re hydrophilicity yavo uye oleophilicity. Iyo yakakura kukosha kweHLB, iyo yakasimba iyo hydrophilicity, uye iyo diki kukosha kweHLB, kusimba kweiyo oleophilicity.

Iyo yakawanda yakawanda inodyiwa emulsifiers isiri-ionic surfactants ine HLB tsika kubva ku0 kusvika 20. Izvo zvakasiyana-siyana zveHLB tsika uye hukama hwakabatana hwevasiri-ionic emulsifiers inoratidzwa mutafura; HLB kukosha kweionic surfactants ndeye 0-40. Nokudaro, emulsifiers ane HLB values ​​<10 inonyanya lipophilic, nepo emulsifiers ane HLB values ​​≥ 10 ane hydrophilic maitiro.

Kune akasanganiswa emulsifiers, ayo HLB hunhu ane ekuwedzera zvivakwa. Naizvozvo, kana maviri kana anopfuura emulsifiers akasanganiswa uye akashandiswa, kukosha kweHLB kweiyo yakasanganiswa emulsifier inogona kuverengerwa zvichienderana nehupamhi hwechikamu cheemulsifier yega yega mukuumbwa kwayo:

HLBa,b =HLBa·A%+HLBb·B%

Mune formula,

HLBa, b kukosha kweHLB kwe emulsifier a, b yakasanganiswa pamwechete;

HLBa neHLBb ndiwo maitiro eHLB emulsifiers a uye b, zvichiteerana;

A% neB% zvikamu zvemukati zvea uye b mune yakasanganiswa emulsifier, zvichiteerana (formula iyi inongoshanda kune asiri-ionic emulsifiers).
Kugadzirira nzira uye kupesvedzera zvinhu zve emulsifiers

Pane nzira ina dzekugadzira emulsifiers, dzinoti yakaoma gel nzira, wet gel nzira, mafuta-mvura chikamu kusanganisa nzira, uye mechaniki nzira.

Dry gel nzira, iyo inosanganisira kuwedzera mvura kune chikamu chemafuta chine emulsifiers. Panguva yekugadzirira, rubber powder (emulsifier) ​​inotanga kusanganiswa zvakaenzana nemafuta, imwe huwandu hwemvura inowedzerwa, pasi uye emulsified mu colostrum, uye inonatswa nemvura kusvika kuhuwandu hwakazara.

Wet gel nzira, iyo inosanganisira kuwedzera mafuta kuchikamu chemvura chine emulsifiers. Panguva yekugadzirira, gel (emulsifier) ​​inotanga kunyungudutswa mumvura kuti iite slurry sechikamu chemvura. Zvadaro, chikamu chemafuta chinowedzerwa kuchikamu chemvura mumatanho, pasi mu colostrum, uye mvura inowedzerwa kune yakazara.

Sakanidza zvikamu zvemafuta nemvura uye wozviwedzera kune emulsifier, kusanganisa imwe huwandu hwemafuta nemvura. Geya chingamu yechiArab muduri, wobva wakuya musanganiswa wemafuta-mvura mucolostrum, wobva wawedzera nemvura.

Kugadzirira kwe emulsifiers kunonyanya kusanganisa emulsifying zvinwiwa zviviri, uye kunaka kwe emulsification kune zvakakosha pamhando ye emulsion.

Izvo zvinhu zvinokanganisa emulsification zvinonyanya zvinosanganisira tension yemukati, viscosity uye tembiricha, emulsification nguva, uye huwandu hweemulsifier inoshandiswa. Emulsifiers inogona kuderedza zvakanyanya kushushikana kwechiso inowanzosarudzwa; Iyo yakanyanya kukodzera emulsification tembiricha ye emulsifiers inotenderedza 70 ℃. Kana asiri-ionic surfactants akashandiswa se emulsifiers, tembiricha ye emulsification haifanire kudarika tembiricha yavo yepamusoro; Iyo yakawanda emulsifiers inoshandiswa, iyo yakanyanya kugadzikana iyo emulsion yakaumbwa.
