Zogulitsa zathu zazikulu: Amino silicone, lolekani siliclilic, ma fluoritic awo Indonesia, Uzbekistan, etc.

Ndi kusintha kwa miyezo ya anthu, zofuna za ogwiritsa ntchito chakudya sizimangokhala ndi phindu lopatsa thanzi labwino, komanso zimafunikira chakudya kuti likhale labwino kwambiri ngati mawonekedwe, mtundu, fungo, kuwoneka, zatsopano, zatsopano, zatsopano.

Emulsifierers, monga zowonjezera za chakudya zowongolera, amatenga gawo lofunikira mu malonda. Tiyeni tiwone magwiridwe antchito a emulsifiers!

Emuliki

Emulsion wamba mu chakudya imakhala ndi madzi kapena njira yothetsera matendawa, imaphatikizidwa ndi gawo la hydrophilic; Gawo lina ndi gawo lamphamvu kwambiri lomwe limakhala ndi madzi, lomwe limadziwika kuti lipophilic gawo la lipophilic. Zakumwa ziwiri zosatheka, monga madzi ndi mafuta, zimatha kupanga mitundu iwiri ya emulsions pomwe zosakanikirana, zimathirira madzi (O / W) ndi madzi mu mafuta (W / O) emulsions.

M'madzi a emulsion, mafuta amabalalitsidwa ngati madontho tating'onoting'ono m'madzi, ndi madontho a mafuta monga kubalalitsa gawo ndi madzi monga kubalalitsa sing'anga. Mwachitsanzo, mkaka wa ng'ombe ndi o / d emulsion; Madzi m'madzi m'magetsi, izi ndi zoona. Madzi amabalalika ngati madontho tating'onoting'ono mu mafuta, ndi madzi ngati obalalitsa gawo ndi mafuta monga momwe amabalalitsa sing'anga. Mwachitsanzo, batala wopanga ndi mtundu wa W / O emulsion.

Makina a zochita za emulsifierers

Ma emulsifiers, omwe amadziwikanso kuti okonda, ndi zinthu zomwe zimasinthira zakumwa zosatheka mu magawo ocheperako (emulsions). Mukawonjezera chakudya, amatha kuchepetsa kwambiri pakati pamafuta ndi madzi, kulola mafuta osavomerezeka (zinthu hydrophobic) ndi madzi (hydrophic) kupanga emu yokhazikika ngati chakudya chokhazikika ngati chakudya.

Kudzanja limodzi, emulsifierers amapanga ma molecular wosanjikiza gawo lokhalokha pagawo, kuchepetsa mphamvu zaulere pa dongosolo lonse ndikupanga mawonekedwe atsopano. Mamolekyu a emulsifeer ali ndi magulu a hydrophilic ndi oleophilic magwiridwe, omwe amatha kutsatsa gawo lokhazikika pagawo la mafuta ndi madzi, ndikupanga mawonekedwe opyapyala ndikuchepetsa kusamvana kwachipongwe pakati pa magawo awiriwo. Ndiye kuti, gawo la oleophilic la molekyulu yamafuta ndipo emulsifier ili mbali imodzi, ndipo hydrophilic gawo la molekyu lamadzi ndipo emulsifier ili mbali inayo. Kulumikizana kumeneku pakati pa awiriwo kumapangitsa kuti asakhale ovutikira;

Kumbali inayo, popanga ma adsorption adsorption otetezedwa pamwamba pa dontho, imataya dontho limodzi ndi kukhazikika kwamphamvu. Ma emulsifierers ambiri amawonjezeredwa, kuchepa kwakukulu mu zovuta zina. Izi zimathandiza kuti zomwe kale sizingaphatikizidwe mosiyanasiyana, ndikupanga dongosolo lomwazikana lomwe limasinthiratu lomwe limasintha dziko loyambirira, potengera kuchuluka kwa chakudyacho ndikulimbikitsa mtundu wake.
Hydrophilic ndi Oleopefilic Equilibrium

Nthawi zambiri, emulsifiers okhala ndi hydrophilicity wamphamvu amapanga mafuta / madzi emulsions, pomwe ma emulsiliers okhala ndi hydrophilicity wamphamvu amapanga madzi / mafuta amafuta. Kuwonetsa ma hydrophilic ndi lipophfilic moyenera kwa emulsifiers, hlbrophilic mtengo wa phulatic moyenera) nthawi zambiri amagwiritsidwa ntchito, ndipo mtengo wa HLB umagwiritsidwa ntchito kuyimira hymurophilicity wa emulsificity wa emulsificity wa emulsificity wa emulsifility wa emulsifility. Pali njira zingapo zowerengera za mtengo wa HLB,

Kusiyanitsa: HLB = Hydrophilicity ya Hydrophilic Gulu - Hydrophobicity of Lipophilic Gulu

Ratio formula: hlb = hydrophilicity wa hydrophilic gulu la ma Oleopehilic

Mtengo wa HLB wa emulsifier iliyonse imatha kutsimikiziridwa ndi njira zoyesera. Kwa ma emulsifiers okhala ndi lipophilicity, hlb yawo ndi 0 (yoyimiridwa ndi parafini ya 100% ya mankhwala osokoneza bongo a hydrophilicity ndi oleophilicity. Chokulirapo kwa HLB, champhamvu cha hydrophilicity, ndi chocheperako cha HLB, champhamvu cholengo.

Ambiri mwa emulsifiers ndiopanda ionic surfactonts omwe ali ndi ma HLB miyezo yochokera ku 0 mpaka 20 Mtengo wa HLB wa ionic surfactonts ndi 0-40. Chifukwa chake, ma emulsifiers okhala ndi ma <10 amakhulupirira Lipophilic, pomwe ma emulsifiers ali ndi HLB Promrees ≥ 10 khalani ndi machitidwe a hydrophilic.

Chifukwa cha ma emulsifiers osakanikirana, malingaliro awo a HLB ali ndi katundu wowonjezera. Chifukwa chake, ma emulsifiers awiri kapena kupitilira apo amasakanikirana, mtengo wa HLB wa Emulsifier ikhoza kuwerengedwa kutengera chidutswa chilichonse cha emulsifier iliyonse.

Hlba, b = hlba ·% + hlbb ·%

Mu fomula,

Hlba, b ndi mtengo wa HLB wa emulsifair a, b ndi pamodzi;

Hlba ndi HLB ndi mfundo za HLB ya ma emulsifierraers A ndi B, motero;

A% ndi B% ndi omwe ali pagawo la a ndi b m'malo osakanikirana, motsatana (njirayi imangogwiritsa ntchito emulsifiers osagwirizana).
Kukonzekera Njira ndi Kukopa Zinthu Zochititsa Zinthu za Amitu

Pali njira zinayi zokonzera ma emulsifiers, njira youma gel, njira yonyowa ya gel, gawo lamadzi osakanikirana njira, komanso njira yochitira makina.

Njira yowuma gel, yomwe imaphatikizapo kuwonjezera madzi m'gawo lamafuta lomwe limakhala ndi emulsifiers. Pokonzekera, ufa wa mphira (emulsifier) ​​umasakaniza woyamba ndi mafuta, madzi ochulukirapo amawonjezeredwa, kenako ndikuchepetsedwa ndi madzi.

Njira yonyowa ya gel, yomwe imaphatikizapo kuwonjezera mafuta m'gawo lamadzi lomwe lili ndi emulsifiers. Pokonzekera, gels (emulsifier) ​​imasungunuka koyamba m'madzi kuti apange malo osalala ngati gawo lamadzi. Kenako, gawo la mafuta limawonjezedwa ndi gawo lamadzi mu magawo, pansi ku colostrum, ndipo madzi amawonjezeredwa kwathunthu.

Sakanizani mafuta ndi magawo amadzi ndikuwonjezera ku Emulsifier, kusakaniza mafuta ndi madzi. PRAPING Chigmufu kukhala matope, kenako ndikupera madzi osakaniza ndi mafuta kukhala colostrum, ndikuchepetsa ndi madzi.

Kukonzekera kwa ma emulsifiers makamaka kumaphatikizapo kukweza zakumwa ziwiri, ndipo mtundu wa emulsization umakhala ndi vuto lalikulu pa emulsion.

Zinthu zomwe zimapangitsa emulsiercation makamaka kuphatikizira kusokonezeka kwa ziwopsezo, mafayilo ndi kutentha, nthawi ya emulsifice, ndi kuchuluka kwa emulsifier omwe amagwiritsidwa ntchito. Ma emulsifeers omwe amatha kuchepetsa kwambiri kusokonezeka kwa nthawi zambiri amasankhidwa; Kutentha koyenera kwambiri kwa ma emulsifeers kuli pafupifupi 70 ℃. Ngati osagwirizana ndi oionic ogwiritsa ntchito ngati ma emulsifiers, kutentha kwa emulsita sikuyenera kupitirira kutentha kwawo; Ma emulsifeers ambiri amagwiritsidwa ntchito, kukhazikika kokhazikika komwe kumapangidwa.
