Kodi Starch Ether ndi chiyani?

Wowuma ether ndi mawonekedwe osinthidwa a wowuma, chakudya chochokera ku zomera. Kusinthaku kumaphatikizapo njira zamakina zomwe zimasintha mawonekedwe a wowuma, zomwe zimapangitsa kuti chinthucho chikhale ndi zinthu zabwino kapena zosinthidwa. Ma ethers owuma amagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana chifukwa cha mawonekedwe awo apadera. Mitundu ina yodziwika bwino ya ma starch ethers ndi monga hydroxyethyl starch (HES), hydroxypropyl starch (HPS), ndi carboxymethyl starch (CMS). Nazi zinthu zazikulu za starch ethers:

1. Kusintha kwa Chemical:

• Hydroxyethyl Starch (HES): Mu HES, magulu a hydroxyethyl amayambitsidwa ku molekyulu ya wowuma. Kusintha kumeneku kumawonjezera kusungunuka kwake m'madzi ndikupangitsa kuti ikhale yoyenera kugwiritsidwa ntchito m'mankhwala, monga plasma voliyumu yowonjezera, ndi ntchito zina.
• Hydroxypropyl Starch (HPS): HPS imapangidwa poyambitsa magulu a hydroxypropyl pamapangidwe a wowuma. Kusintha kumeneku kumapangitsa kuti zinthu monga kusungunuka kwamadzi komanso kupanga mafilimu, zikhale zothandiza m'mafakitale monga chakudya, nsalu, ndi zomangamanga.
• Carboxymethyl Starch (CMS): CMS imapangidwa poyambitsa magulu a carboxymethyl ku mamolekyu owuma. Kusintha kumeneku kumapereka zinthu monga kusungika bwino kwa madzi, kukhuthala, ndi kukhazikika, zomwe zimapangitsa kuti zikhale zofunikira pakugwiritsa ntchito monga zomatira, nsalu, ndi mankhwala.

2. Kusungunuka kwamadzi:

• Ma starch ether nthawi zambiri amasungunuka bwino m'madzi poyerekeza ndi wowuma wamba. Izi kumatheka kusungunuka ndi kopindulitsa mu formulations kumene kusungunuka mofulumira kapena kubalalitsidwa m'madzi kumafunika.

3. Mawonekedwe a Viscosity ndi Makulidwe:

• Wowuma ethers amagwira ntchito ngati thickeners amphamvu m'mitundu yosiyanasiyana. Zimathandizira kukulitsa kukhuthala, komwe kuli kofunikira pakugwiritsa ntchito monga zomatira, zokutira, ndi zakudya.

4. Kutha Kupanga Mafilimu:

• Ma ether ena owuma, makamaka wowuma wa hydroxypropyl, amawonetsa kupanga mafilimu. Izi zimawapangitsa kukhala oyenera kugwiritsa ntchito komwe kumafuna kupanga filimu yopyapyala, yosinthika, monga m'mafakitale azakudya ndi mankhwala.

5. Kukhazikika ndi Kumanga Katundu:

• Ma ethers owuma amagwiritsidwa ntchito ngati zokhazikika komanso zomangira m'mapangidwe osiyanasiyana. Amathandizira kukhazikika kwa ma emulsion ndikuthandizira kuyanjana kwazinthu monga mapiritsi amankhwala.

6. Ntchito Zomatira:

• Ma etha wowuma amagwiritsidwa ntchito mu zomatira, m'makampani azakudya (mwachitsanzo, m'malo mwa chingamu cha arabic) komanso osagwiritsa ntchito zakudya (mwachitsanzo, pamapepala ndi zomatira).

7. Kukula kwa Nsalu:

• M'makampani opanga nsalu, ma starch ethers amagwiritsidwa ntchito popanga masaizi kuti apangitse kulimba komanso kusalala kwa ulusi pakuluka.

8. Ntchito Zamankhwala:

• Ma ether ena owuma amagwiritsidwa ntchito popanga mankhwala. Mwachitsanzo, wowuma wa hydroxyethyl amagwiritsidwa ntchito ngati plasma voliyumu yowonjezera.

9. Zomangamanga ndi Zomangamanga:

• Ma starch ethers, makamaka hydroxypropyl starch ndi carboxymethyl starch, amagwiritsidwa ntchito pomanga, makamaka popanga matope osakaniza. Amathandizira kuti kumamatira bwino, kugwira ntchito bwino, komanso kusunga madzi.

10. Makampani a Chakudya:

11. Biodegradability:

12. Kuganizira za chilengedwe:

Ndikofunika kuzindikira kuti katundu ndi ntchito za starch ethers zimatha kusiyana kutengera mtundu wa kusinthidwa ndi ntchito yomwe akufuna. Opanga amapereka mwatsatanetsatane zaukadaulo wamtundu uliwonse wa ether wowuma kuti aziwongolera okonza posankha mtundu woyenera kwambiri pamapulogalamu awo enieni.
