Lub cev thiab tshuaj muaj zog
Span series emulsifiers yog ntau yam esters tsim los ntawm polyol derivatives ntawm cov fatty acids sib txawv thiab sorbitans. Xws li sorbitol ester (I), 1, 4-fatty acid sorbitan ester (II), fatty acid isosorbide ester (III), thiab txawm tias me me ntawm Di fatty acid sorbitan ester thiab tri fatty acid sorbitan ester. Feem ntau cov fatty acids yog lauric acid, oleic acid, palmitic acid, thiab stearic acid. Span series emulsifiers yog non-ionic thiab lipophilic emulsifiers, nrog HLB qhov tseem ceeb ntawm 1.8 txog 8.6. Raws li lawv cov khoom emulsifying, lawv zoo dua li lwm cov emulsifiers hauv cov khoom noj muaj roj.
Cov emulsifiers sib txawv hauv cov span series qhia lipophilic muaj peev xwm thiab qhov sib txawv vim lawv cov sib txawv fatty acids Amber viscous kua, lub teeb daj los yog xim av daj, cov hlaws me me los yog flake wax zoo li cov khoom, nrog cov ntxhiab tsw tshwj xeeb thiab muag muag. Soluble nyob rau hauv organic solvents xws li ethanol, methanol, ether, ethyl acetate, thiab roj av ether, insoluble nyob rau hauv dej txias, thiab dispersible nyob rau hauv dej kub. Nws yog dej hauv cov roj emulsifier nrog HLB tus nqi ntawm 8.6, tus txheeb ze ntom ntom ntawm 1.00 ~ 1.06, thiab melting point ntawm 14 ~ 16 degree . Nws yog npaj los ntawm cua sov sorbitol thiab lauric acid rau esterification thiab lub cev qhuav dej.

Kev siv emulsifier
GB {{0}}} npaj: mis nyuj khov, dej khov, dej khov, txiv hmab txiv ntoo tshiab nrog kev kho mob saum npoo, zaub tshiab nrog kev kho saum npoo, khoom qab zib uas tsis yog cov khoom qab zib hauv cov pos hniav, qhob cij, ncuav qab zib, biscuits, txiv hmab txiv ntoo thiab zaub cov kua txiv hmab txiv ntoo (pulp) dej haus, thiab cov dej haus (tshwj tsis yog kas fes instant), nrog kev noj ntau tshaj ntawm 3.0g/kg; Cream (lub teeb cream) thiab nws cov analogues, hydrogenated zaub roj, cocoa khoom, chocolate thiab chocolate khoom (xws li cocoa butter thiab chocolate khoom), instant kas fes thiab qhuav poov xab, nrog ntau npaum li cas ntawm 10.{{15 }}g/kg; Cov khoom lag luam legume (raws li kev noj ib kilogram ntawm soybeans), qhov siab tshaj plaws yog 1.6g / kg; Cov roj, roj thiab cov khoom siv roj emulsified (tshwj tsis yog 02.01.01.01 zaub roj), qhov ntau npaum li cas yog 15.0g / kg; Zaub protein haus, qhov ntau npaum li cas yog 6.0g / kg; Cov dej qab zib (tsuas yog dej haus txiv hmab txiv ntoo), qhov siab tshaj plaws yog 0.5g / kg; Qhov ntau npaum li cas ntawm lwm yam (dej turbidity agent) yog 0.05g / kg.
Sorbitan monolaurate tuaj yeem siv ib leeg lossis sib koom nrog cov khoom noj emulsifiers xws li glycerol ester thiab sucrose ester kom muaj txiaj ntsig zoo. Raws li ib tug stabilizer, nws muaj peev xwm tiv thaiv cov nag lossis daus ntawm dawb fatty acids nyob rau hauv margarine. Nws tuaj yeem siv los ua tus neeg sawv cev turbidity rau cov dej txias uas muaj cov xim. Nws tuaj yeem siv rau zom cov pos hniav kom txo qhov nro ntawm cov pos hniav, tiv thaiv cov pos hniav laus, txhim kho zom zom thiab tiv thaiv cov nag lossis daus ntawm granulated qab zib. Nws kuj tseem siv tau los ua ib qho dispersant xws li cov kua txiv hmab txiv ntoo thiab cov hmoov cocoa.
