Abstract
Biscuits, raws li cov khoom ci uas nrov tshaj plaws, tshuav lawv cov yam ntxwv zoo (xws li crispness, kev ntxhib los mos, zoo li, thiab txee lub neej) feem ntau rau kev siv scientific ntawm emulsifiers hauv formulations. Txawm hais tias feem ntau ntxiv ntawm tsuas yog 0.1%-0.5% ntawm hmoov nplej, emulsifiers txhim kho cov khoom ua tau zoo, cov khoom siv textural, thiab ruaj khov. Daim ntawv no qhia txog cov txheej txheem tseem ceeb ntawm emulsifiers hauv biscuits, suav nrog roj emulsification, kev txhim kho lub khob noom cookie, cov qauv xoob, tiv thaiv -staling preservation, thiab muab cov ncauj lus kom ntxaws txog kev ua haujlwm ntawm cov emulsifiers feem ntau siv xws li monoglycerides, soy lecithin, sodium stearoyl ester monoacet lactylate thiab lactylate. diglycerides (DATEM), sucrose esters, thiab sorbitan monostearate (SPAN), muab cov lus qhia theoretical rau biscuit formulation optimization.
Taw qhia
Biscuits yog cov khoom ci feem ntau yog ua los ntawm cov hmoov nplej, suab thaj, thiab roj / rog, uas yog cov khoom ci los yog mos. Thaum lub sij hawm biscuit ntau lawm, lub xeev dispersion ntawm cov rog, rheological zog ntawm mov paj, nthuav cov nyhuv thaum lub sij hawm ci, thiab zaum kawg cov khoom zoo nkauj thiab txee lub neej yog tag nrho cov nyob ze rau daim ntawv thov ntawm emulsifiers. Raws li nto -cov khoom siv, emulsifiers tuaj yeem tsim cov yeeb yaj kiab adsorption ntawm cov roj- dej cuam tshuam, txo cov kev sib tshuam ntawm lub ntsej muag thiab yog li txhim kho cov tshuab emulsion. Hauv biscuits, emulsifiers txhim kho cov khoom zoo los ntawm ntau lub tswv yim, ua rau lawv cov khoom xyaw tseem ceeb hauv cov qauv biscuit.
Core Functions ntawm Emulsifiers hauv Biscuits
1 Roj Emulsification thiab Uniform Dispersion
Lub luag haujlwm tseem ceeb tshaj plaws ntawm emulsifiers yog los txhawb kev sib cais ntawm cov rog hauv khob noom cookie. Cov rog uas siv rau hauv cov khoom noj biscuit (xws li shortening thiab margarine) yuav tsum tau muab faib ua ib feem ntawm lub khob noom cookie los ua ib qho kev ntxhib los mos. Emulsifiers txo qhov kev sib tshuam ntawm cov roj thiab dej, ua kom cov rog zoo dua thiab tsim cov emulsion ruaj khov, tiv thaiv cov roj exudation. Qhov no sib npaug sib npaug ntawm cov rog ua rau cov yeeb yaj kiab tsis tu ncua thaum lub sijhawm ci, muab cov biscuits lawv qhov tshwj xeeb crispy zoo nkauj.
2 Txhim kho cov hmoov nplej ua tiav
Emulsifiers ho txhim kho cov txheej txheem txheej txheem ntawm lub khob noom cookie. Thaum lub khob noom cookie sib tov, emulsifiers cuam tshuam nrog gluten proteins, tswj cov gluten network qauv kom muab lub khob noom cookie tsim nyog elasticity thiab extensibility. Qhov no yog tshwj xeeb tshaj yog ib qho tseem ceeb rau mechanical forming thiab demolding. Piv txwv li, sodium stearoyl lactylate (SSL) ua kom yooj yim demolding ntawm biscuits, zoo nkauj tsos, thiab ntshiab txheej. Tsis tas li ntawd, emulsifiers tiv thaiv lub khob noom cookie los ntawm kev ua raws li cov menyuam yaus, txhim kho kev tsim khoom.
3 Txhawb nqa cov qauv kev xoos
Thaum lub sij hawm ci, emulsifiers txhawb kev tsim cov qauv xoob hauv biscuits. Kev tshawb fawb qhia tau hais tias diacetyl tartaric acid ester ntawm mono- thiab diglycerides (DATEM) nthuav thaum rhuab thaum lub sij hawm ci, ua rau cov proteins ua npuas yooj yim, nce ntim thiab maj mam solidifying nrog ci, tsim ib daim txhuam cev porous - zoo li xoob qauv hauv nruab nrab txheej . Cov qauv xoob no ncaj qha cuam tshuam rau biscuit crispness thiab qhov ncauj.
4 Tswj Fat Crystallization
Emulsifiers tuaj yeem tswj hwm tus cwj pwm crystallization ntawm cov rog, cuam tshuam rau biscuit textural zog. Cov kev tshawb fawb tau pom tias cov microstructure thiab lub cev muaj zog ntawm emulsifier-raws li oleogels muaj feem cuam tshuam rau biscuit zoo. Biscuits npaj nrog monoacylglycerol (MAG) thiab sorbitan monostearate (SPAN) pom zoo li hardness thiab xim rau shortening biscuits, nrog uniformly ntxeem tau ntoo khaub lig-section . Ntau dua shear viscosity (ntawm 25 degree) tau pom tias yog ib qho tseem ceeb rau kev tsim cov ncuav qab zib softer.
5 Antioxidant teebmeem thiab txee lub neej Extension
Qee cov emulsifiers nthuav tawm cov teebmeem antioxidant lossis tuaj yeem ua ke nrog cov tshuaj antioxidants. Kev tshawb fawb qhia tau hais tias nyob rau hauv cov ncuav qab zib khaws cia ntawm 40℃rau 12 lub hlis, lecithin pom muaj zog antioxidant teebmeem. Sorbitan monostearate kuj pom muaj kev sib koom ua ke thaum sib xyaw nrog tocopherol concentrates. Tsis tas li ntawd, emulsifiers tuaj yeem cuam tshuam nrog amylose, retarding starch retrogradation thiab tiv thaiv biscuit deterioration.
6 Txo cov rog rog
Daim ntawv thov ntawm emulsifiers tuaj yeem ua tiav cov roj txo thaum tswj cov khoom zoo. Cov kev tshawb fawb qhia tias ntxiv 0.125-0.5% DATEM tuaj yeem txo cov roj cov ntsiab lus hauv biscuits li ntawm 20%, ua tiav cov txiaj ntsig kev noj qab haus huv yam tsis muaj kev cuam tshuam kev noj qab haus huv. Hauv kev txo cov rog biscuit, SSL kuj tau pom tias muaj txiaj ntsig zoo hauv kev txhim kho kev hnov lus zoo.
