Waa maxay sababta casiirka miraha loogu baahan yahay in la pasturized?

Casiirka furuutka leh khudradda sida alaabta ceeriin iyada oo loo marayo hababka jireed sida cadaadiska, centrifugation, soo saarista iyo casiirka kale, oo lagu farsameeyo cabitaano ka samaysan alaab.Casiirka khudradu waxa uu hayaa inta badan nafaqooyinka ku jira midhaha, sida fiitamiinada, macdanta, sonkorta, iyo pectin-ka ku jira faybarka cuntada.
Muddada ilaalinta ee casiirka miraha waa mid aad u gaaban, inta badan sababtoo ah saameynta microorganisms, sababtoo ah dhaqdhaqaaqa dheef-shiid kiimikaadka ee microorganisms ee casiirka khudradda ayaa aad u firfircoon, sidaas darteed waxaa si gaar ah muhiim u ah in la doorto tignoolajiyada jeermiska ee ku habboon si looga hortago sii xumaanshaha cabitaannada casiirka khudradda. .Marka laga hadlayo nadiifinta cabitaannada casiirka, waxaa loo baahan yahay in la dilo bakteeriyada pathogenic iyo bakteeriyada kharribtay ee casiirka, xakamaynta tirada guud ee gumeysiga ayaa la kulma heerarka qaranka, iyo sidoo kale burburinta enzymes ee casiirka si ay u yeeshaan ilaalin gaar ah. muddada deegaan gaar ah;Midda kale waa in la ilaaliyo qaabka nafaqada iyo dhadhanka casiirka sida ugu badan ee suurtogalka ah ee habka jeermiska.
Habka nadiifinta kulul ee casiirka khudradda, waxaa jira pasteurization (habka jeermiska heerkulka hoose ee muddada dheer), habka jeermiska heerkulka sare ee wakhtiga gaaban iyo habka jeermiska degdegga ah ee heerkul aad u sarreeya.Heerkulka sare ee wakhtiga gaaban ee saamaynta nadiifinta kulaylka ayaa ka fiican, laakiin heerkulku inta badan wuxuu keenaa saameyn xun tayada casiirka khudradda, sida isbeddelka midabka, dhadhanka, nafaqo-darrada, iwm.
Iyo tignoolajiyada pasteurization, adoo bedelaya borotiinka iyo qaab dhismeedka enzyme ee unugyada microbial, sidaas darteed xannibaya dhaqdhaqaaqa enzymes, dilaya tiro badan oo bakteeriyada kharriban iyo bakteeriyada pathogenic ee casiirka khudradda, halka dareenka iyo qiimaha nafaqada ee cuntada aan la saameyn doonin.Ma aha oo kaliya in la gaaro ujeedada sterilization iyo passivation ee enzymes at heerkul hoose, laakiin sidoo kale kaa caawin in la ilaaliyo midabka casiirka miro, udgoonka, dhadhanka, nafaqada iyo cusub, si ay u buuxiyaan shuruudaha macaamiisha u doodaya "dabiiciga ah iyo caafimaadka" cuntada.Sidaa darteed, barashada tignoolajiyada pasteurization waxay muhiimad weyn u leedahay badbaadada, midabka iyo nafaqada casiirka khudradda cusub.
Waxaa xusid mudan in pasteurization ay tahay qasac ama casiir dhalada ah, haddii ay tahay casiir dhalada ah, waxay u baahan tahay in la tixgeliyo dhibaatada ka hor kulaylka iyo qaboojinta, si looga hortago kala duwanaanshaha heerkulku waa mid aad u weyn oo keena dhalada dillaacsan, sidaas awgeed mishiinkeena baastada ayaa loo qaybiyaa afar qaybood, kuwaas oo kala ah kulaylka hore, jeermiska, pre-qaboojinta iyo qaboojinta, laakiin magaca guud waa mashiinka pasteurization juice.
