Imisebenzi:
Isodium Metabisulfite sisixhobo esisetyenziswa ngokubanzi ekutyeni. Ukongeza kwisiphumo sokwenza mhlophe, ikwanemisebenzi elandelayo:
1) Iziphumo zeAnti Browning
I-Enzymatic Browning ihlala isenzeka kwiziqhamo, iitapile, i-Sodium Metabisulfite yindlela yokunciphisa, umsebenzi we-polyphenol oxidase unefuthe elinamandla lokuthintela, i-0.0001% yesalfure dioxide inokunciphisa i-20% yomsebenzi we-enzyme, i-0.001% yesalfure dioxide inokuthintela ngokupheleleyo Umsebenzi we-enzyme, unokuthintela i-enzymatic Browning; Ukongeza, inokusebenzisa ioksijini kwizihlunu zokutya kwaye idlale indima yokufumana amandla emzimbeni. I-Sulfite kulongezo lokuphendula kunye ne-glucose, kuthintela iswekile kukutya kunye ne-amino acid glycoammonia reaction, yiyo loo nto inefuthe lokulwa neBrown.
2) Isiphumo sokubola
Isulfurous acid ingadlala indima yokubamba iasidi, ukungadibani nesalfurous acid kukholelwa ukuba inqanda igwele, ukungunda, ibhaktiriya.I-sulfite engahambelaniyo inikwe ingxelo yokuba inamandla okuphinda-phinda ama-1000 kune-bisulfite ekuthinteleni i-E.coli. igwele lebhiya kunye namaxesha ali-100 omelele ukubumba. Xa isalfure dioxide ine asidi, inefuthe elinamandla ekuthwaleni iintsholongwane.
3, Umsebenzi arhente ziba
Ingasetyenziswa njengamacandelo earhente yokukhulula.
3) Isiphumo se-Antioxidant.
I-Sulfite inefuthe elikhulu le-oxidation, kuba i-acid ye-sulfurous iyinto ekwehlisayo eyomeleleyo, inokuthi itye ioksijini kwiziqhamo nakwimifuno, ukuthintela umsebenzi we-oxidase, ukutshatyalaliswa kwe-oxidation ye-vitamin C ekuthinteleni iziqhamo nemifuno kusebenza kakhulu.
Indlela yokusebenza yesodium metabisulfite:
I-Bleach ngokwendlela yokusebenza inokwahlulwahlulwa ibe ziindidi ezimbini: iOxidation Bleach kunye nokuNcitshiswa kweBleach. Isodium metabisulfite yinto yokunciphisa izinto.
Umbala wezona zinto zininzi eziphilayo zithathwe kumaqela e-chromaticity equlethwe kwiimolekyuli zawo.Amaqela ombala weenwele aneebond ezingafakwanga, ukunciphisa i-bleach ukukhupha iiathom zehydrogen kunokwenza ukuba umbala weenwele uqulethwe kwibhondi engafakwanga ibhondi enye, izinto eziphilayo ziya kulahla umbala. Olunye uhlobo lokutya I-browning lubangelwa bubukho be-ion ene-ferric, ukongeza ukunciphisa i-bleach kunokwenza ii-ions ze-ferric zibe-ion ze-ferric, ukuthintela ukutya uku-browning.
Isodiyam metabisulfite iblitshi ngokudibanisa iisulfite. I-Anthocyanin kunye noshukela zinokuhlanjululwa ngokongeza impendulo. Le mpendulo iyabuyela umva, kwaye i-asidi yesalfure ingasuswa ngokufudumeza okanye nge-asidi, ukuze i-anthocyanin iphinde iphinde iphinde iphinde ibuyiselwe umbala wayo obomvu wokuqala.
Kwimizi-mveliso yeebhiskithi, isodiyam metabisulfite isetyenziswa njengesiqhushumbisi senhlama. Ngaphambi kokuba isetyenziswe, ilungiselelwe kwisisombululo se-20%, emva koko yongezwe kwintlama engekavuthwa ngamaxesha ahlukeneyo ngexesha lokwenziwa kwentlama. Ngenxa yesalfure dioxide ekhutshwe yi-sodium pyrosulphate kwinkqubo yokulungiselela intlama, ukomelela kunye nokuqina komgubo we-gluten zinkulu kakhulu, kwaye inani elincinci lokudibanisa linokuthintela ukuvela kweemveliso zebhasikithi ngenxa yamandla agqithisileyo.Inhlama enzima inokongezwa ngokwamandla omgubo, kwaye ngokubanzi kwinani eliphezulu leoyile kunye neswekile crisp intlama kunye nentlama emnandi kangangoko kunokwenzeka ukungasebenzisi, oku kungenxa yokuba ukongezwa kweoyile kunye neswekile ngokwayo kuthintele ukwanda kokufakwa kwamanzi kwiprotein, kuthintela ukwenziwa kwenani elikhulu le-gluten, akukho mfuneko yokongeza i-sodium metabisulfite.
Amanqaku okuqwalaselwa ekusebenziseni i-sodium metabisulfite:
Amanqaku alandelayo kufuneka aqatshelwe xa usebenzisa i-sodium metabisulfite kukutya okucutshungulwayo:
I-1) i-arhente yokunciphisa i-sodium metabisulfite, isisombululo sayo asizinzanga kwaye asizinzanga, ngoku iyasetyenziswa, ukuthintela ukungazinzi kwesulfite kunye ne-volatilization.
2) xa kukho ion zentsimbi ekutyeni, i-residual sulfite ingenziwa i-oxidized; Ingenza nokwehla kwe-pigment oxidation discoloration, ngaloo ndlela kuncitshiswe ukusebenza kwe-bleach.Ngoko ke, ii-chelators zentsimbi ziyasetyenziswa ngexesha lokuvelisa.
3) ukusetyenziswa kwezinto ze-sulfite bleaching, ngenxa yokunyamalala kwesalfure dioxide kunye nombala olula, zihlala ke kwintsalela yokutya eseleyo isalfure dioxide, kodwa intsalela yentsalela ayinakugqitha umgangatho
I-4) i-Sulfuric acid ayinakho ukuthintela umsebenzi we-pectinase, eya konakalisa umanyano lwe-pectin.Ukongeza, ukungena kwe-asidi yesalfure kwizihlunu zeziqhamo, ukwenziwa kweziqhamo ezaphukileyo, ukuze kususwe yonke i-dioxide yesalfure, ukuze iziqhamo zigcinwe i-asidi yesalfure ilungele kuphela ukwenza ijam, iziqhamo ezomisiweyo, iwayini yeziqhamo, iziqhamo eziswiti, azinakusetyenziswa njengezinto ezingafunwayo zeenkonkxa.
I-5) I-Sulfites inokuyitshabalalisa i-thiamine, ngenxa yoko akukho lula ukuyisebenzisa ekutyeni kwentlanzi. 6) I-Sulfites kulula ukuyiphendula ngealdehydes, ketoni, protein, njl.
Iindlela kunye noPhuhliso:
Kwicandelo lokulungiswa kokutya okwangoku, kuba ukutya ngamanye amaxesha kuvelisa umbala ongathandekiyo, okanye ukutya okwaveliswa kukutya ngenxa yokwahluka, ukuthuthwa, iindlela zokugcina, ixesha lokuvuthwa, umbala wahlukile, onokuthi ukhokelele kwimveliso yokugqibela ukuhambelana kunye nokuchaphazela umgangatho wokutya.Ngoko ke, kunamhlanje nangakumbi kumgangatho wokutya, ukuphuculwa kokutya kwearhente yokuhlanjululwa kokutya akunamda, kunjalo, njengoluhlobo lwearhente yokudlala ukutya, ukuphuculwa kwesodiyam metabisulfite nako kulungile. I-metabisulfite inoluhlu olubanzi lwemisebenzi, ayisiyiyo kuphela indima ye-bleaching, kodwa ikwanendima ye-oxidation, indima yokuthintela i-enzymatic Browning, indima ye-antisepsis, indlela yayo yemveliso ilula kwaye ilula, kwimeko yokuqinisekisa ukhuseleko lokutya. , indawo yophuhliso lwe-sodium metabisulfite inkulu kakhulu.
