Akwụkwọ nzacha oyi nke ndị China – Akwụkwọ nzacha mmanụ kwesịrị ekwesị maka ụdị nzacha mmanụ niile – Great Wall

1. Njirimara ojiji nke akwụkwọ nzacha mmanụ a na-eri:
• Ọ na-eguzogide okpomọkụ dị elu. A pụrụ itinye ya na mmanụ ogo 200 ruo ihe karịrị ụbọchị iri na ise.
• Nwere oke nkezi oghere efu. Mee ka ihe ruru unyi dị n'ime ya karịa micron iri. Mee ka mmanụ e ji esi nri doo anya ma doo anya, ma mezuo ebumnuche nke ịchacha ihe ahụ e ji esi nri n'ime mmanụ ahụ.
• O nwere nnukwu ikuku na-abata, nke nwere ike ime ka ihe e ji mmanụ mee nke nwere oke viscosity na-agafe nke ọma, ọsọ nzacha ahụ dịkwa ngwa ngwa.
• Ike dị elu nke kpọrọ nkụ na mmiri mmiri: mgbe ike mgbawa ruru 300KPa, ike nrụgide ogologo na nke transverse bụ 90N na 75N n'otu n'otu.

2. Uru nke akwụkwọ nzacha mmanụ a na-eri:
• Nwere ike iwepụ ihe ndị na-akpata kansa dịka aflatoxin n'ime mmanụ e ji esi nri nke ọma.
• Nwere ike iwepụ isi ọjọọ dị na mmanụ e ji esi nri.
• Nwere ike iwepụ abụba efu, peroxides, nnukwu molekul polymers na ihe ndị na-adịghị ọcha n'ime ájá a kpọchiri akpọchi n'ime mmanụ e ji esi nri.
•Ọ nwere ike ime ka agba mmanụ e ji esi nri ka mma nke ọma ma mee ka o nweta agba doro anya nke mmanụ salad.
•Ọ nwere ike igbochi mmeghachi omume nke oxidation na mmeghachi omume nke mmiri ọkụ, melite mma mmanụ e siri esi, melite ịdị ọcha nke nri e siri esi, ma mee ka ndụ nri e siri esi dịkwuo ogologo.
• Enwere ike iji mmanụ e ji esi nri mee ihe nke ọma n'okpuru iwu maka ịdị ọcha nri, na-eweta uru akụ na ụba ka mma nye ụlọ ọrụ. A na-ejikarị ngwaahịa a eme ihe n'ọtụtụ ụdị nzacha mmanụ e ji esi nri.
Ihe ndekọ ụlọ nyocha gosiri na iji akwụkwọ nzacha mmanụ a na-eri eri na-arụ ọrụ dị mkpa n'igbochi mmụba nke uru acid nke mmanụ a na-esi esi nri, ọ dịkwa oke mkpa n'imeziwanye gburugburu ebe a na-esi esi nri, imeziwanye mma ngwaahịa, na ịgbatị ndụ nchekwa ngwaahịa.
