Kodi wowuma wosinthidwa ndi chiyani?

Wowuma wosinthidwa amatanthauza wowuma yemwe wasinthidwa mwakuthupi kapena mwakuthupi kuti apititse patsogolo magwiridwe antchito ake pazinthu zina. Wowuma, wopangidwa ndi carbohydrate polima wopangidwa ndi mayunitsi a shuga, amapezeka muzomera zambiri ndipo amagwira ntchito ngati gwero lalikulu lamphamvu kwa anthu ndi nyama. Mastachi osinthidwa amagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana, kuphatikiza chakudya, mankhwala, nsalu, ndi kupanga mapepala. Nazi mwachidule za sitachi yosinthidwa:

Njira Zosinthira:

1. Kusintha kwa Chemical: Njira zama mankhwala zimaphatikizapo kuchiza wowuma ndi zidulo, ma alkali, kapena ma enzyme kuti asinthe mawonekedwe ake. Njira zodziwika bwino zosinthira mankhwala zimaphatikizapo etherification, esterification, cross-linking, oxidation, ndi hydrolysis.
2. Kusintha Kwathupi: Njira zakuthupi zimaphatikizapo mawotchi kapena matenthedwe ochiritsira kuti asinthe mawonekedwe a wowuma popanda kusintha kwa mankhwala. Njirazi zikuphatikizapo kutentha, kumeta ubweya, extrusion, ndi crystallization.

Makhalidwe a Modified Starch:

• Kukhuthala ndi Gelling: Zowuma zosinthidwa zimawonetsa kukhuthala bwino komanso kununkhira bwino poyerekeza ndi zokometsera zakubadwa, zomwe zimawapangitsa kukhala zowonjezera pazakudya monga sosi, soups, gravies, ndi zokometsera.
• Kukhazikika: Zakudya zosinthidwa zitha kukhala zokhazikika kuzinthu monga kutentha, asidi, kumeta ubweya, ndi kuzizira, zomwe zimapangitsa kuti pakhale ntchito yabwino pakukonza ndi kusunga chakudya.
• Viscosity Control: Zowuma zosinthidwa zitha kupangidwa kuti zipereke mawonekedwe enieni a mamasukidwe akayendedwe, kulola kuwongolera bwino momwe zimapangidwira komanso kusasinthika kwazakudya.
• Kumvekera bwino: Zakudya zina zosinthidwa zimapereka kumveka bwino komanso kumveka bwino pamayankho, kuwapangitsa kukhala oyenera kugwiritsidwa ntchito pazakudya zomveka bwino kapena zowoneka bwino.
• Kukhazikika kwa Freeze-Thaw: Zakudya zina zosinthidwa zimawonetsa kukhazikika kwa kuzizira, kuwapangitsa kukhala oyenera kugwiritsidwa ntchito muzakudya zachisanu.

Mapulogalamu:

1. Makampani a Chakudya: Mastachi osinthidwa amagwiritsidwa ntchito kwambiri monga zokometsera, zotsitsimutsa, zopangira ma gelling, ndi zokometsera zakudya zosiyanasiyana, kuphatikizapo sosi, mavalidwe, soups, ndiwo zamasamba, zinthu zophika buledi, ndi nyama zokonzedwa.
2. Mankhwala: M'makampani opanga mankhwala, masitache osinthidwa amagwiritsidwa ntchito ngati zomangira, zosungunula, zodzaza, ndi zotulutsa zoyendetsedwa bwino pamapangidwe amapiritsi ndi mitundu ina ya mlingo wapakamwa.
3. Zovala: Ma starch osinthidwa amagwiritsidwa ntchito popanga nsalu kuti azitha kulimbitsa ulusi, mafuta, komanso mtundu wa nsalu panthawi yoluka ndi kumaliza.
4. Kupanga Mapepala: Popanga mapepala, masitayesi osinthidwa amagwiritsidwa ntchito ngati zinthu zoyezera pamwamba, zomangira zokutira, ndi zowonjezera zamkati kuti apange mphamvu zamapepala, kusindikiza, ndi mawonekedwe apamwamba.
5. Zomatira: Zomata zosinthidwa zimagwiritsidwa ntchito ngati zomangira ndi zomatira pazinthu zosiyanasiyana, kuphatikiza kupanga mapepala, malata, ndi plywood.

Chitetezo ndi Malamulo:

• Ma starches osinthidwa omwe amagwiritsidwa ntchito pazakudya ndi mankhwala amayenera kuyang'aniridwa ndi malamulo ndipo ayenera kutsatira mfundo zachitetezo zomwe zimakhazikitsidwa ndi mabungwe olamulira monga Food and Drug Administration (FDA) ku United States ndi European Food Safety Authority (EFSA) ku European Union. .
• Mabungwe owongolerawa amawunika chitetezo cha zowuma zosinthidwa kutengera zinthu monga chiyero, kapangidwe kake, kagwiritsidwe ntchito koyenera, ndi zotsatira zake paumoyo.

Ma starches osinthidwa amagwira ntchito yofunika kwambiri m'mafakitale osiyanasiyana, popereka magwiridwe antchito komanso kusinthika kwazinthu zosiyanasiyana. Posintha mamolekyu a wowuma, opanga amatha kusintha mawonekedwe ake kuti akwaniritse zofunikira zina, zomwe zimapangitsa kuti zinthu zikhale bwino, kukhazikika, komanso kukhutitsidwa ndi ogula.
