Methylcellulose (MC) ndi chochokera ku cellulose chomwe chimagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana chifukwa cha mawonekedwe ake apadera. Ndi polima yosungunuka m'madzi yomwe imachokera ku cellulose, yomwe imachokera ku nkhuni, thonje, kapena zomera zina. MC imagwiritsidwa ntchito kwambiri m'mafakitale azakudya, azamankhwala, ndi zomangamanga monga chowonjezera, emulsifier, binder, ndi stabilizer. M'nkhaniyi, tikambirana zakuthupi za MC ndi ntchito zake zosiyanasiyana.

Thupi la Methylcellulose

MC ndi ufa woyera mpaka beige wopanda fungo komanso wosakoma. Imasungunuka m'madzi ndipo imapanga yankho lomveka bwino, lowoneka bwino likasungunuka m'madzi. Kukhuthala kwa njira yothetsera vutoli kungasinthidwe mwa kusintha ndende ya yankho. Kuchuluka kwa MC, kumapangitsanso kukhuthala kwa yankho. MC imakhala ndi kuchuluka kwa madzi osungira ndipo imatha kuyamwa mpaka 50 kulemera kwake m'madzi. Katunduyu amapangitsa MC kukhala yokhuthala bwino, emulsifier, ndi stabilizer.

Chimodzi mwazinthu zapadera kwambiri za MC ndikutha kwake kupaka gel ndi kutentha. MC ikatenthedwa pamwamba pa kutentha kwina, imapanga chinthu chonga gel. Katunduyu amadziwika kuti kutentha kwa gelation (GT) ndipo amadalira kuchuluka kwa kusintha (DS) kwa MC. DS ndi chiwerengero cha magulu a methyl omwe amalumikizidwa ndi tcheni cha cellulose. Kukwera kwa DS, ndikokwera GT ya MC. Katunduyu amapangitsa MC kukhala chinthu choyenera pazakudya zosiyanasiyana monga zophika buledi, ma jellies, ndi zokometsera.

Kugwiritsa ntchito methylcellulose

1. Makampani a Chakudya: MC imagwiritsidwa ntchito kwambiri m'makampani azakudya monga chowonjezera, emulsifier, binder, ndi stabilizer. Amagwiritsidwa ntchito popanga buledi, zinthu zamkaka, ndi nyama zokonzedwa. MC imagwiritsidwanso ntchito muzakudya zokhala ndi mafuta ochepa komanso zopatsa mphamvu zochepa kuti zisinthe mawonekedwe ake komanso kumva kwapakamwa.
2. Makampani Opanga Mankhwala: MC imagwiritsidwa ntchito m'makampani opanga mankhwala monga binder, disintegrant, komanso kupanga mafilimu. Izo ntchito piritsi formulations kusintha azingokhala ndi kuwonongeka katundu piritsi. MC imagwiritsidwanso ntchito muzolemba zam'mutu monga thickener ndi emulsifier.
3. Makampani Omanga: MC imagwiritsidwa ntchito pantchito yomanga ngati chomangira komanso chokhuthala muzinthu zopangidwa ndi simenti. Amawonjezeredwa ku simenti kuti apititse patsogolo kugwira ntchito kwake komanso kupewa kulekanitsa ndi kutaya magazi.
4. Makampani Osamalira Munthu: MC imagwiritsidwa ntchito m'makampani osamalira anthu monga chowonjezera, emulsifier, komanso chokhazikika muzodzikongoletsera monga mafuta odzola, mafuta opaka, ndi ma shampoos. Amagwiritsidwa ntchito kupititsa patsogolo kukhuthala komanso kukhazikika kwa mankhwalawa.
5. Makampani a Paper: MC imagwiritsidwa ntchito pamakampani opanga mapepala ngati zokutira komanso ngati chomangira popanga mapepala. Zimawonjezeredwa ku zamkati zamapepala kuti ziwonjezere mphamvu ndi kukana madzi kwa pepala.

Ubwino wa Methylcellulose

1. Otetezeka: MC imawonedwa kuti ndi yotetezeka kuti igwiritsidwe ntchito ndi mabungwe olamulira monga Food and Drug Administration (FDA) ndi European Food Safety Authority (EFSA). Zayesedwa mozama za chitetezo ndipo zavomerezedwa kuti zigwiritsidwe ntchito muzakudya ndi mankhwala.
2. Zosiyanasiyana: MC ndi chinthu chosunthika chomwe chitha kugwiritsidwa ntchito m'mafakitale osiyanasiyana. Maonekedwe ake apadera a thupi amapangitsa kuti ikhale yolimba kwambiri, emulsifier, binder, ndi stabilizer.
3. Zotsika mtengo: MC ndi chinthu chotsika mtengo poyerekeza ndi zokhuthala zina, ma emulsifiers, ndi okhazikika.
4. Shelf-Stable: MC ndi chinthu chokhazikika chomwe chimatha kusungidwa kwa nthawi yayitali osawonongeka. Izi zimapangitsa kuti ikhale yoyenera pazinthu zosinthidwa zomwe zimafuna moyo wautali wa alumali.
5. Kupititsa patsogolo Kapangidwe: MC imatha kukonza kapangidwe kazakudya powonjezera kukhuthala kwawo ndikupereka mawonekedwe osalala, okoma. Ikhozanso kusintha kamvekedwe ka mkamwa ndi kuchepetsa malingaliro a grittiness mu zakudya zina.
