lub luag haujlwm ntawm emulsifiers hauv cov khoom ci ci (I) yog dab tsi?
Aug 11, 2021
Emulsifiers tuaj yeem" yaj" cov roj thiab dej uas siv tsis tau hauv cov khoom ci ci. Xaiv cov emulsifier uas tsim nyog raws li hom khoom ci ci, cov emulsifier tuaj yeem siv cov txiaj ntsig zoo tshaj plaws, thiab cov khoom lag luam tau zoo dua qub.
Emulsifier yog surfactant nrog hydrophilic thiab lipophilic pawg. Nws tuaj yeem ua rau ob theem uas siv tsis tau (xws li roj thiab dej) sib xyaw ua ke thiab tsim kev sib faib sib cais lossis lub cev emulsified, yog li hloov lub cev qub. Tam sim no, vim kev txhim kho thev naus laus zis ua zaub mov noj, emulsifiers ua lub luag haujlwm tseem ceeb hauv cov txheej txheem ua zaub mov noj. Lawv tau muaj txiaj ntsig zoo los ntawm kev lag luam bakery thiab tau siv dav hauv cov khoom lag luam bakery, yog li hloov cov qauv sab hauv ntawm cov khoom thiab txhim kho cov khoom lag luam zoo. Xaiv cov emulsifiers sib txawv raws li cov khoom sib txawv ntawm cov khoom tuaj yeem ua lub luag haujlwm tseem ceeb hauv qab no hauv cov khoom lag luam zoo:
1. Cov emulsifiers tuaj yeem txhim kho cov roj khaws cia ntawm gluten thiab khob noom cookie. Hauv cov khoom ci, emulsifiers tuaj yeem cuam tshuam nrog cov protein gluten thiab ntxiv dag zog rau cov txheej txheem gluten network, yog li huab cua khaws cia ntawm lub khob noom cookie tuaj yeem txhim kho, thiab nws kuj tseem tuaj yeem ua rau tsis kam ntawm lub khob noom cookie rau cov khoom siv cuam tshuam thiab hloov pauv hauv qhov kub fermentation. Hauv cov txheej txheem ntawm cov hmoov sib sau ua ke, gluten ua cov qauv zoo li network. Yog tias cov qauv tsis muaj zog, CO2 tsim los ntawm cov poov xab yuav ploj mus. Thaum emulsifiers xws li DATEM, SSL, thiab lwm yam tau ntxiv rau hauv lub khob noom cookie, cov qauv gluten tau ua kom muaj zog, kom cov pa roj carbon CO2 tsim tau zoo.
2. Cov emulsifier tuaj yeem tsim cov txheej txheem txheej txheej du ntawm gluten thiab hmoov txhuv nplej siab. Cov qauv no ua rau gluten tswj tau zoo thiab txo qhov viscosity ntawm lub khob noom cookie, yog li ua kom ductility ntawm gluten protein network, ua rau cov khoom muag muag thiab yooj yim dua. Hauv qhov no, cov txiaj ntsig ntawm sodium stearoyl lactylate/calcium (CSL/SSL) yog qhov zoo tshaj plaws.
