N'ụzọ bụ isi, usoro mmeghachi omume nke carbohydrates niile nke Fischer mebere na alkyl glycosides nwere ike belata na ụdị usoro abụọ, ya bụ, njikọ kpọmkwem na transacetalization. N'ọnọdụ abụọ ahụ, mmeghachi omume nwere ike ịga n'ihu na batches ma ọ bụ na-aga n'ihu.
N'okpuru njikọ kpọmkwem, carbohydrate na-emeghachi omume ozugbo na mmanya na-egbu egbu ka ọ bụrụ alkyl polyglycoside ogologo agbụ achọrọ. A na-akpọkarị carbohydrate a na-eji eme ihe tupu mmeghachi omume n'ezie (dịka ọmụmaatụ iwepu mmiri kristal ma ọ bụrụ na glucose monohydrate = dextrose). Nzọụkwụ ihicha a na-ebelata mmeghachi omume akụkụ nke na-eme n'ihu mmiri.
Na njikọ kpọmkwem, a na-eji ụdị glucose monomer siri ike mee ihe dị ka ezigbo particulate siri ike. Ebe ọ bụ na mmeghachi omume bụ mmeghachi omume siri ike / mmiri mmiri na-enweghị isi, a ghaghị ịkwụsịtụ ihe siri ike kpamkpam na mmanya.
Sirop glucose mebiri emebi nke ukwuu (DE>96; DE=Dextrose dakọtara) nwere ike meghachi omume na njikọ gbanwetụrụ ozugbo. iji ihe mgbaze nke abụọ na / ma ọ bụ emulsifiers (dịka ọmụmaatụ alkyl polyglycoside) na-enye mgbasawanye nke ọma n'etiti mmanya na glucose sirop.
Usoro transacetalization nke okpukpu abụọ chọrọ akụrụngwa karịa njikọ kpọmkwem. Na ọkwa nke mbụ, carbohydrate na-emeghachi omume na mmanya dị mkpụmkpụ (dịka ọmụmaatụ n-butanol ma ọ bụ propylene glycol) na nhọrọ na-ebuga-menzes. Na ọkwa nke abụọ, a na-atụgharị alkyl glycoside dị mkpụmkpụ na mmanya mmanya dị ogologo ogologo iji mepụta alkyl polyglycoside achọrọ. Ọ bụrụ na molar ratio nke carbohydrate na mmanya bụ otu, nkesa oligomer nwetara na usoro nke transacetalization bụ isi otu ihe ahụ enwetara na kpọmkwem njikọ.
Ọ bụrụ na ejiri oligo-na polyglycoses (dịka ọmụmaatụ starch, sirop nwere uru DE dị ala), a na-etinye usoro transacetalization. Depolymerization dị mkpa nke ihe mmalite ndị a chọrọ okpomọkụ nke>140 ℃. Ọ dabere na mmanya na-aba n'anya nke a na-eji, nke a nwere ike ịmepụta nrụgide dị elu kwekọrọ na ya nke na-ebute ihe ndị ọzọ siri ike na ngwá ọrụ ma nwee ike ibute ọnụ ahịa osisi dị elu. N'ozuzu, n'otu ikike ahụ, mmepụta usoro transacetalization na-efu karịa njikọ kpọmkwem. na mgbakwunye na usoro mmeghachi omume abụọ ahụ, a ghaghị ịnye ụlọ ọrụ nchekwa ndị ọzọ, yana ụlọ ọrụ nhọrọ maka obere mmanya mmanya. N'ihi adịghị ọcha pụrụ iche na starch (dị ka protein), alkyl glycosides ga-enwerịrị nnụcha ọzọ ma ọ bụ dị mma. N'ime usoro transacetalization dị mfe, syrups nwere nnukwu glucose dị elu (DE> 96%) ma ọ bụ ụdị glucose siri ike nwere ike meghachi omume na mmanya dị mkpụmkpụ n'okpuru nrụgide nkịtị, usoro na-aga n'ihu na-emepụta na nke a.
