Ụlọ ọrụ dị ka Elkana na Netherlands na Kuras dị na Northern Europe emeela ọmụmụ ihe gbasara protein dị na ụdị starch nduku, gụnyere Désirée na Bintje, bụ ndị ama ama n'etiti ndị Europe. Nnyocha ha na-ekewa protein ndị soluble sitere na tubers nduku ụzọ atọ: protein patatin, proteinase inhibitors, na protein ndị ọzọ.


Liu Gang, onye okachamara na ojiji nke ngwaahịa sitere na ụlọ ọrụ nduku nke mba, depụtara ụzọ atọ bụ isi maka mmịpụta protein nduku:

Ụzọ mkpuchi Acid-Thermal:

Ụfọdụ nnukwu ụlọ ọrụ starch nduku na Netherlands na Germany emejuputala protein mgbake site na mmiri mkpofu nke nhazi starch iji wedata akụkụ nke ụgwọ ọgwụgwọ mmiri mkpofu. Ụzọ ndị ha na-eji na-agụnye itinye uche na mbụ site na iji reverse osmosis membranes, na-esote ikpo ọkụ na-ekpo ọkụ na n'ikpeazụ ikewa na ihicha protein ndị agbakọtara.

Usoro a kapịrị ọnụ maka mgbake protein sitere na starch nduku na-edozi mmiri mkpofu site na iji usoro acid-thermal coagulation na-agụnye ịhazigharị pH nke mmiri mkpofu ka ọ bụrụ 3.5-5.5, kpoo ya ihe karịrị 90°C, na-akpata denaturation protein na coagulation. A na-ekewapụ protein ndị a jikọtara ọnụ na mmiri site na iji centrifugation na akpọnwụwo n'ime protein ntụ ntụ. Usoro nchikota acid-thermal nke ọtụtụ ụlọ ọrụ starch nduku na-eji na-ewepụta ịdị ọcha protein karịrị 80%, ọdịnaya ntụ n'etiti 1.5% na 3.0%, yana agba dị obere.

Otú ọ dị, protein ndị e nwetara site na acid-thermal coagulation nwere adịghị ike solubility, na mmiri dị ala, na ike absorption mmanụ, na-efunari ọtụtụ ọrụ ọrụ dị mkpa maka ngwa nri, dị ka ụfụfụ na ụfụfụ kwụsie ike. N'ihi ya, ojiji ha na ụlọ ọrụ nri dị oke. N'agbanyeghị uru protein nduku nwere nnukwu nri, ọ naghị esiri ya ike pụtara na protein nduku etinyebere na-anọgide na-abụ ihe na-abaghị uru site na nhazi starch. A na-eji protin nduku akwadoro site na iji usoro coagulation acid-thermal dị ka nri anụmanụ, omenala maka ehi na ezi, na enweela mbọ iji dochie nri azụ dị ka nri azụ.

Chromatography gbasara ihe ndina gbasaara:

chromatography ihe ndina gbasasịrị bụ ụzọ kachasị mma maka ị nwetaghachi protein na-arụ ọrụ sitere na starch nduku na-edozi mmiri mkpofu. Ọ bụghị naanị na protein ndị ahụ enwetara na-ejigide ọrụ ndu ha mana enwere ike kewapụ ma nwetaghachi ya na ihe dị iche iche maka protein patatin na protease inhibitors site na iji mgbasa ozi mgbasa ozi dị iche iche na ọnọdụ elution.
