Elona qondo lobushushu lokomisa umbona kwindawo yokomisa umbona.
Kutheni kufuneka iqondo lobushushuisomisi sokutyakulawulwe?
EHeilongjiang, eTshayina, ukomisa yinxalenye ebalulekileyo yenkqubo yokugcina umbona. Okwangoku, uninzi lweenkampani zokugcina ukutya okuziinkozo kwiPhondo laseHeilongjiang zisebenzisa iinqaba ezomileyo njengoomatshini bokumisa umbona. Nangona kunjalo, iindlela zokomisa kunye nezinye izinto zangaphandle zihlala zichaphazela umgangatho wombona. Okokuqala, isakhiwo senqaba yokumisa singenangqiqo, esibangela iikona ezifileyo kwigumbi lokumisa apho ingqolowa ifudumala khona, okubangelwa ukomisa okungalinganiyo; okwesibini, indlela umbona ongena ngayo nophuma ngayo inokubangela umonakalo kumbona; okwesithathu, fan ukomisa ekhoyoisomisi sombonaidla ngokufunxa igesi yobushushu obuphezulu kunye nentlantsi kumbhobho, itshise umbona, ivelise iinkozo ezitshisiweyo, kwaye ichaphazela umgangatho wombona; okwesine, inqaba ekhoyo yokomisa ikakhulu itshisa amalahle akrwada ngexesha lokomisa. Uninzi lwala malahle akrwada awakaphathwa nangayiphi na indlela. Xa zitshiswa kwiziko elibaswe ngesandla okanye kwiziko elitshiswe ngumatshini, igesi yobushushu obuphezulu yobushushu iyawungcolisa umbona.
Impembelelo yenkqubo yokomisa kumgangatho wombona
Eyona njongo yokomisa kukunciphisa ukufuma kombona kwangethuba ukuqinisekisa ukugcinwa okukhuselekileyo. Kwiinkqubo yokomisa umbona, ingqolowa ayisusi nje ubuninzi bokufuma, kodwa iphinda itshabalalise umgangatho wendalo wombona ukuya kumlinganiselo othile. Amalungu aphambili ombona sisitatshi, iiprotheyini kunye namafutha. Xa ubushushu bomileyo buphezulu kakhulu, isitashi kunye neprotheyini ziya kuba yigelatin kunye ne-denature, ngaloo ndlela zilahlekelwa izondlo zazo zangaphambili. Ngoko ke, ulawulo lobushushu bokoma lubalulekile kumgangatho wombona.
Impembelelo kwistatshi
Isiqulatho se-starch kwi-corn yi-60% ukuya kwi-70%, kwaye isitashi senziwe nge-starch granules ezinobungakanani obahlukeneyo. Ngokuqhelekileyo, isitashi asinyibiliki emanzini abandayo kodwa sinyibilika emanzini ashushu. Isitashi siya kudumba emva kokunyibilika emanzini. Utshintsho alubonakali ngaphantsi kwe-57 ° C. Xa iqondo lokushisa lidlula i-57 ° C, ngakumbi xa iqondo lokushisa liphezulu kakhulu, i-cornstarch inokuthi i-gelatinize (ukubonakala kutshiswa), isakhiwo siya kutshintsha, i-viscosity ye-steaming iya kuncipha, akulula ukwenza ibhola, i-flavour iya kutshintsha. ukulahleka xa kudliwe, incasa iya kuhlukana, kwaye kuya kubakho umfanekiso oncamathelayo, okubangela ukuhla komgangatho wombona.
Impembelelo kwiprotheni kunye ne-enzymes
Umxholo weprotheyini kumbona umalunga ne-11%. Yi-hydrophilic colloid kunye nobushushu obunamandla. Ummbila uya kuhombisa kwiqondo lokushisa eliphezulu, kwaye ukukwazi kwawo ukufunxa amanzi kunye nokudumba kuya kuncipha. Okukhona iqondo lobushushu liphezulu, kokukhona iqondo le-denaturation likhulu. Iqondo lobushushu kufuneka lilawulwe ngokungqongqo ngexesha lokumisa, eyona nto iphambili ekugcinweni komgangatho wemvula. I-enzyme yiprotheni ekhethekileyo. Umbona lukhozo kunye nento ephilayo. Zonke iinkqubo zayo ze-biochemical zicutshungulwa kwaye zilawulwe zii-enzymes ezahlukeneyo. Umsebenzi we-enzymes uyanda ngokunyuka kweqondo lokushisa. Nangona kunjalo, xa ubushushu budlula i-55 ℃, umsebenzi wee-enzymes uqala ukwehla. Ukuba iqondo lokushisa liyaqhubeka nokunyuka, i-enzyme inokuthi i-denature kwaye umsebenzi wayo uya kutshatyalaliswa.
Impembelelo kumafutha
Amafutha embona akatshintshi kakhulu ngaphantsi kwe 50℃. Ukuba iqondo lobushushu lingaphezulu kwe-60℃, amanqatha aya kuba yi-rancid ngenxa ye-oxidation kwaye amafutha ayakubola abe ziiasidi ezinamafutha. Iqondo lobushushu eliphezulu lokomisa liyakwandisa ixabiso leasidi enamafutha ombona. Umbona onexabiso eliphezulu le-asidi enamafutha akulula ukuwugcina, kwaye incasa iba muncu kwaye umgangatho uyancipha.
Impembelelo kwi-cellulose
I-Cellulose yi-polysaccharide ebalulekileyo kwingqolowa. Umxholo wefiber wombona owomileyo uyancipha ngokunyuka kweqondo lokumisa, kuba ubushushu obuphezulu kakhulu buya kuvelisa ukutshisa, umxholo wefiber uya kuncipha, kwaye enye ifayibha iya kuguqulwa ibe yifurfural. Ke ngoko, kwishishini lotywala, ulawulo lweenkozo ezitshisiweyo lungqongqo, kuba i-furfural eveliswa kwiinkozo ezitshisiweyo iya kunciphisa ixabiso le-oxidation yeemveliso zotywala kwaye ichaphazele umgangatho wotywala.
Impembelelo kwiivithamini
Iivithamini kumbona ziquka A, B, E, D kunye no C. Xa ubushushu bungaphezu kwe 50℃, iivithamin E, B kunye no C ziyakutshintsha. Ngoko ke, ukushisa kokumisa kufuneka kulawulwe ngexesha lokumisa. Ukuba iqondo lokushisa liphezulu kakhulu, iivithamini ziya kutshatyalaliswa ngukushisa okuphezulu.
Impembelelo kumgangatho wenkangeleko
Ukuziqhelanisa kubonise ukuba ubushushu obuqhelekileyo benkozo obungaphantsi kwe-50℃ bunefuthe elincinane kumbala kunye nencasa yombona; xa ubushushu bengqolowa buphakathi kwe-50 kunye ne-60 ℃, umbala wombona uba khaphukhaphu kwaye ivumba lokuqala liyancipha kakhulu; xa ubushushu benkozo bungaphezulu kwe 60℃, umbona uba ngwevu kwaye uphulukane nencasa yawo yakuqala. Ukuba ubushushu bokomisa abulawulwa kakuhle ngexesha lokomisa, inani elikhulu leenkozo ezitshisiweyo liya kuveliswa, okanye ukufuma kwezinye iinkozo kuya kuba ngaphantsi kakhulu, okuya kubangela ukuba iinkozo zombona ziphuke ngexesha lokuthuthwa okanye ukuhanjiswa, ukwandisa inani leenkozo ezingafezekanga, kwaye unganyamezeli ukugcinwa, okuchaphazela umgangatho wombona.
