Kedu ihe bụ starch emezigharịrị?

Starch emezigharịrị na-ezo aka na starch agbanweela na kemịkalụ ma ọ bụ n'anụ ahụ iji melite njirimara arụ ọrụ ya maka ngwa akọwapụtara. Starch, polymer polymer nke nwere nkeji glucose, dị ukwuu n'ọtụtụ osisi ma na-eje ozi dị ka isi iyi ike maka mmadụ na anụmanụ. A na-eji starch emezigharịrị eme ihe n'ọtụtụ ụlọ ọrụ dị iche iche, gụnyere nri, ọgwụ, textiles, na imepụta akwụkwọ. Nke a bụ ntụle nke starch emezigharịrị:

Ụzọ nke ime mgbanwe:

1. Mgbanwe kemịkalụ: Ụzọ kemịkalụ gụnyere iji acid, alkalis, ma ọ bụ enzymes agwọ starch iji gbanwee usoro ihe omimi ya. Usoro mgbanwe kemịkalụ na-emekarị gụnyere etherification, esterification, cross-linking, oxidation, na hydrolysis.
2. Ngbanwe anụ ahụ: Ụzọ anụ ahụ na-agụnye ọgwụgwọ igwe ma ọ bụ thermal iji gbanwee njirimara anụ ahụ nke starch na-enweghị mgbanwe kemịkal. Ụzọ ndị a na-agụnye ikpo ọkụ, ịkwa osisi, extrusion, na crystallization.

Njirimara nke starch emezigharịrị:

• Ịba ụbara na Gelling: Starches emezigharịrị na-egosipụta ihe na-eme ka ọ dịkwuo mma ma e jiri ya tụnyere starch obodo, na-eme ka ha bụrụ ihe mgbakwunye bara uru na ngwaahịa nri dị ka sauces, ofe, gravies, na desserts.
• Nkwụsi ike: starch agbanweela nwere ike ime ka nkwụsi ike na ihe ndị dị ka okpomọkụ, acid, shear, na friza cycles, na-enye ohere maka ịrụ ọrụ ka mma na nhazi na nchekwa nri.
• Njikwa viscosity: Enwere ike ịhazi starch emezigharịrị iji nye profaịlụ viscosity akọwapụtara nke ọma, na-enye ohere maka njikwa ziri ezi na nhazi na nkwekọ nke ngwaahịa nri.
• Idozi: Ụfọdụ starch emezigharịrị na-enye nchapụta anya na nghọta na ngwọta, na-eme ka ha dabara adaba maka ojiji na ngwaahịa nri doro anya ma ọ bụ translucent.
• Nkwụsi ike Freeze-Thaw: Ụfọdụ starch emezigharịrị na-egosipụta nkwụsi ike ka oyi na-atụ, na-eme ka ha dabara adaba maka ojiji na ngwaahịa nri jụrụ oyi.

Ngwa:

1. Ụlọ ọrụ nri: A na-eji starch emezigharịrị eme ihe n'ọtụtụ ebe dị ka ndị na-ekpu mmiri, ndị na-eme ka ahụ sie ike, ndị na-ahụ maka gelling na emulsifier n'ụdị nri dị iche iche, gụnyere sauces, uwe, ofe, desserts, ihe ebe a na-eme achịcha, na anụ edoziri.
2. Ọgwụ: N'ime ụlọ ọrụ na-emepụta ọgwụ, a na-eji starch emezigharị eme ihe dị ka ihe nchikota, ihe na-agbasa, ihe ndochi, na ihe ntọhapụ na-achịkwa n'ụdị mbadamba na ụdị usoro onunu ndị ọzọ.
3. Akpụkpọ anụ: A na-eji starch emezigharịrị emezigharị na nha akwa iji kwalite ike yarn, mmanu na akwa n'oge a na-akpa akwa na ngwucha.
4. Nrụpụta akwụkwọ: N'ịme akwụkwọ, a na-eji starch emezigharị eme ihe dị ka ihe na-eme ka ihe dị n'elu, ihe mkpuchi mkpuchi, na ihe mgbakwunye dị n'ime iji meziwanye ike akwụkwọ, mbipụta, na ihe ndị dị n'elu.
5. Adhesives: A na-eji starch emezigharịrị eme ihe dị ka ihe nchikota na nrapado na ngwa dị iche iche, gụnyere laminating akwụkwọ, corrugating, na imepụta plywood.

Nchekwa na ụkpụrụ:

• Starches emezigharịrị eji na nri na ngwa ọgwụ bụ n'okpuru nlekọta usoro iwu na ọ ga-agbasorịrị ụkpụrụ nchekwa nke ụlọ ọrụ na-achịkwa dịka nri nri na ọgwụ ọjọọ (FDA) na United States na European Safety Authority (EFSA) na European Union guzobere. .
• Ụlọ ọrụ nchịkwa ndị a na-enyocha nchekwa nke starches gbanwetụrụ dabere na ihe ndị dị ka ịdị ọcha, ihe mejupụtara, ojiji e bu n'obi mee, na mmetụta ahụike nwere ike ime.

Starches emezigharịrị na-arụ ọrụ dị oke mkpa n'ọtụtụ ụlọ ọrụ, na-enye akụrụngwa arụ ọrụ ka mma yana ụdị maka ngwa dị iche iche. Site n'ịgbanwe usoro mkpụrụ ndụ nke starch, ndị na-emepụta nwere ike ịhazi ihe onwunwe ya iji mezuo ihe achọrọ arụ ọrụ, na-eduga n'ịdị mma ngwaahịa, nkwụsi ike, na afọ ojuju ndị ahịa.
