Ị maara ihe e ji mara Protein osikapa bụ?

N'ime protein nke cereal, protein osikapa bụ protein osisi nwere nnukwu ihe oriri na-edozi ahụ. Ọ bụghị naanị na ọ nwere nnukwu uru bayoloji (BV), mana ọ bara ụba na amino acid dị mkpa yana ọdịnaya lysine dị elu karịa nke ọka ndị ọzọ. Tụkwasị na nke ahụ, protein osikapa nwere àgwà nke hypoallergenicity, ọ dịghị nnyonye anya pigmenti na uto dị nro nke soy na mmiri ara ehi enweghị ike ịkwado. Ya mere, protein osikapa adọtala nlebara anya site na ụlọ ọrụ nri.

1. Solubility nke protein osikapa

Solubility bụ otu n'ime ihe ndị dị mkpa na-ekpebi ọrụ Njirimara nke nri protein, n'ihi na solubility nke protein na-emetụta ya emulsification, ụfụfụ na gelation Njirimara, ma si otú na-arụ a bụrụkwa ọrụ ya ngwa na nri.

Ihe solubility nke protein osikapa gbanwere site na pH, na protein osikapa ọhụrụ (LTRPC) nwere solubility dị mma karịa protein osikapa omenala (HTRPC). Na acidic na alkaline ngwọta n'okpuru ọnọdụ nke solubility nke LPRTC karịa na-anọpụ iche ngwọta n'okpuru ọnọdụ nke ukwuu elu, nke a bụ tumadi n'ihi na osikapa protein gluten na-achị, na irighiri gluten mebere nke ọtụtụ nnukwu ụmụ irighiri site disulfide bond guzobe. , crosslinking na cohesion, onye ọ bụla ọzọ banyere 80% nke gluten ike soluble na-anọpụ iche nnu ngwọta, nwere ike na-etisasịwo na itughari acid, itughari alkali. Ndekọ solubility nke 60% gosiri na a na-ezere denaturation nke protein osikapa nke ọma n'oge usoro dum. Otú ọ dị, maka HTRPC, mgbanwe mgbanwe ya abụghị ihe doro anya dị ka nke LTRPC, nke nwere ike ịbụ n'ihi denaturation nke protein osikapa mgbe ọgwụgwọ okpomọkụ dị elu, nke na-agbanwe usoro ya ma na-eduga ná mgbanwe nke solubility ya.

2. Blister of protein osikapa

Ụfụfụ na-ezokarị aka n'usoro agbasasị agbasa na mmiri mmiri na-aga n'ihu ma ọ bụ akụkụ nke ọkara nke nwere surfactants soluble. N'ihi na protein osikapa nwere otu hydrophobic na hydrophilic, ọ nwere ọrụ elu ma nwee ike ịmepụta ụfụfụ mgbe a kpalitere ya kpamkpam. Ezi ụfụfụ ike na ụfụfụ kwụsie ike bụ ihe a chọrọ maka protein na elu solubility, n'ihi na etisasịwo protein nwere ike ngwa ngwa gbasaa ikuku / mmiri interface, na ngwa ngwa, enrichment na-agbasa, gburugburu na-egbuke egbuke ụdị adsorption film, nke mere ka ibelata elu esemokwu. N'otu oge ahụ, ihe ndị na-edozi ahụ na-adịghị edozi ahụ nwere ike imeziwanye viscosity elu ma na-arụ ọrụ bara uru na nkwụsi ike nke ụfụfụ. LTRPC ọ bụghị naanị nwere ikike ịfụfụ dị mma, kamakwa ezigbo nkwụsi ike nke ụfụfụ. Maka HTRPC, obere solubility na-eduga n'ike ịfụfụ dị ala na ọbụna nkwụsi ike ụfụfụ ka njọ. Mgbe nkeji iri atọ gachara, ogo ụfụfụ fọrọ nke nta ka ọ bụrụ efu.

3. Ihe emulsification of protein osikapa

Emulsification na-ezo aka n'ikike nke protein iji jikọta mmanụ na mmiri iji mepụta emulsion. N'ihi na protein soluble nwere ike ịgbasa na adsorb na mmanụ / mmiri interface bụ otu n'ime njirimara dị mkpa na-ekpebi ihe onwunwe emulsification nke protein, nnukwu solubility nke protein na-aba uru na emulsification ya. Emulsifying nkwụsi ike na-ezo aka n'ikike mmanụ-mmiri ngwọta iji nọgide na-enwe nkwụsi ike, nke metụtara interfacial esemokwu, protein elu ụgwọ ọnụ ọgụgụ, ngwọta PH, ịta, wdg Site ntụnyere nke LTRPC na HTRPC, ọ bụ ezie na emulsification nke LTRPC dị nso. nke HTRPC, enwere oghere doro anya na nkwụsi ike nke abụọ ahụ. Nsonaazụ ndị a na-egosi na enwere ike iji LTRPC dị ka mgbakwunye protein na-arụ ọrụ nke ọma na nri emulsified.

4. Ike Jide Mmiri of protein osikapa

Ikike nke mmiri na-ejide protein na-ezo aka na mmiri fọdụrụnụ nke protein mgbe centrifugation gasịrị na ụfọdụ ntinye nke protein aqueous ngwọta. Enwere ọnọdụ atọ maka protein iji nweta ezigbo njide mmiri: (1) irighiri protein nwere ike ịzacha nke ọma ma ọ gaghị agbaze mgbe mmiri gwụchara; (2) ahụ protein nwere ezigbo viscosity mgbe rehydration; (3) protein nwere ike ịmepụta netwọk gel. N'iji tụnyere LTRPC na HTRPC, ikike ijide mmiri nke LTRPC dị elu karịa nke HTRPC, nke nwere ike ịbụ n'ihi ọdịiche dị na mmepụta usoro. LTRPC na-ejigide ọrụ ndu ndu mbụ nke protein na-enweghị ọgwụgwọ okpomọkụ dị elu, ebe n'ime usoro mmepụta nke HTRPC, okpomọkụ dị elu karịa 100 degrees Celsius karịrị okpomọkụ nke denaturation nke protein osikapa. Nke a nwere ike gbanwee nhazi nke protein, na-ebute adịghị ike njikọ njikọ nke akụkụ protein mgbe ọzịza gasịrị.
