Kodi ntchito za chakudya cha cellulose ether ndi chiyani?

Fotokozani:

Zakudya zopangidwa ndi zinthuma cellulose ethers

Ntchito yaukadaulo:

Zomwe zapangidwa pano zikugwirizana ndi zakudya zomwe zili ndi ma cellulose ethers.

Njira yakumbuyo:

Zakhala zikudziwika kuti zimaphatikizira ma cellulose ethers m'zakudya, makamaka zopangidwa ndi chakudya, kuti apititse patsogolo zinthu zosiyanasiyana monga kukhazikika kwa chisanu ndi / kapena mawonekedwe, kapena kukulitsa kulimba panthawi yopanga, kukonzedwa ndi makina kapena yokazinga. Kugwiritsa ntchito patent yaku Britain GB 2 444 020 imawulula zolemba zazakudya zomwe zimakhala ndi nonionic cellulose ether monga methylcellulose, hydroxypropyl cellulose, kapena hydroxypropyl methylcellulose. Methylcellulose ndi hydroxypropyl methylcellulose ali ndi "thermos reversible gelling properties". Zimafotokozedwa mwachindunji kuti njira yamadzimadzi ya methylcellulose kapena hydroxypropyl methylcellulose ikatenthedwa, gulu la hydrophobic methoxy lomwe lili mu molekyulu limataya madzi m'thupi, ndipo limakhala gel osakaniza. Kumbali ina, pamene gel opangidwawo atakhazikika, magulu a hydrophobic methoxy amatsitsimutsidwa, momwe gel osakaniza amabwerera ku njira yoyamba yamadzimadzi.

European Patent EP I 171 471 imawulula methylcellulose yomwe imakhala yothandiza kwambiri muzolemba zazakudya zolimba monga masamba olimba, nyama, ndi nyemba za soya chifukwa chakuwonjezeka kwa mphamvu ya gel. Methylcellulose imathandizira kukhazikika komanso kulumikizana kwa chakudya cholimba, motero kumapangitsa kuti ogula azitha kudya zomwe zakonzedwa. Mukasungunuka m'madzi ozizira (mwachitsanzo, 5 ° C kapena pansi) musanayambe kapena mutatha kusakaniza ndi zinthu zina zomwe zimapangidwira chakudya, soya ya methylcellulose imafika pa mphamvu zake zonse kuti ipereke nyimbo zolimba za chakudya chokhazikika komanso chogwirizana. luso.

Komabe, nthawi zina, kugwiritsa ntchito madzi ozizira kumakhala kovuta kwa wopanga chakudya. Chifukwa chake, zingakhale bwino kupereka ma cellulose ethers omwe amapereka nyimbo zolimba za chakudya ndi kuuma kwabwino komanso mgwirizano ngakhale ma cellulose ethers atasungunuka m'madzi okhala ndi kutentha kwapakati.

Hydroxyalkyl methylcellulose monga hydroxypropyl methylcellulose (yomwe imadziwikanso kuti ndi yothandiza muzolemba zazakudya) imadziwika kuti ili ndi modulus yosungiramo yochepa poyerekeza ndi methylcellulose. Ma Hydroxyalkyl methylcelluloses omwe amawonetsa modulus otsika kwambiri sapanga ma gels amphamvu. Kuyika kwakukulu kumafunika ngakhale ma gels ofooka (Haque, A; Richardson; Morris, ER, Gidley, MJ ndi Caswell, DC mu Carbohydrate Polymers22 (1993) p.175; ndi Haque, A ndi Morris, ER1nCarbohydrate Polymers22 (1993) p.161).

Pamene ma hydroxyalkyl methylcellulose monga hydroxypropyl methylcellulose (omwe amawonetsa modulus otsika osungira) amaphatikizidwa muzolemba za chakudya cholimba, kuuma kwawo ndi kugwirizana kwawo sikuli kokwanira pa ntchito zina.

Ndi chinthu chomwe chapangidwa kuti chipereke hydroxyalkyl methylcellulose, makamaka hydroxypropyl methylcellulose, yomwe imafanana ndi hydroxyalkyl methylcelluloses, monga hydroxypropyl methylcellulose Mosiyana ndi zimenezi, nyimbo zolimba za chakudya zimaperekedwa ndi kukhazikika bwino komanso / kapena kugwirizana.

Chinthu chokondedwa cha zomwe zapangidwa panopa ndi kupereka hydroxyalkyl methylcellulose, makamaka hydroxypropyl methylcellulose, yomwe imapereka nyimbo zolimba za zakudya zolimba komanso / kapena mgwirizano ngakhale pamene hydroxyalkyl methylcellulose N'chimodzimodzinso ndi kusungunuka m'madzi okhala ndi kutentha kwa chipinda.

Chodabwitsa, chapezeka kutihydroxyalkyl methylcellulose, makamaka hydroxypropyl methylcellulose, angagwiritsidwe ntchito pokonza Poyerekeza ndi nyimbo zolimba chakudya, odziwika olimba chakudya nyimbo ndi apamwamba kuuma ndi/kapena kugwirizana.

Chodabwitsanso n'chakuti, zapezeka kuti ma hydroxyalkyl methylcelluloses, makamaka hydroxypropyl methylcellulose, safunikira kusungunuka m'madzi ozizira kuti apereke nyimbo zolimba za chakudya chokhazikika komanso / kapena kugwirizana.
