Faʻaaogaina o sodium metabisulfite o meaʻai faʻaopopo

Galuega tauave:
Sodium Metabisulfite o se lautele lautele faʻaaogaina meaʻai faʻaopopo. I se faʻaopopoga i lona faʻamamaina, o loʻo i ai foi galuega taua nei:
1) O le aʻafiaga o Aneti Browning
Enzymatic Browning masani ona tupu i fualaʻau, pateta, Sodium Metabisulfite o se faʻaititia sooupu, o le gaioiga o polyphenol oxidase ei ai le malosi taofiofia aafiaga, 0,0001% o le sulfur dioxide mafai ona faʻaititia 20% o le gaioiga gaioiga, 0,001% o le sulfur dioxide mafai ona taofia atoa le gaioiga o le enzyme, e mafai ona puipuia ai le enzyme Browning; I se faʻaopopoga, e mafai ona faʻaumatia le okesene i meaʻai sela ma faia le matafaioi o deoxygenation. Sulfite i le faʻaopoopoga tali ma glucose, puipuia le suka i meaai ma amino acid glycoammonia tali atu, o lea ua i ai le aʻafiaga o anti Browning.
2) Antiseptic aafiaga
Sulphurous acid mafai ona faia le matafaioi o acid faasao, undissociated sulfurous acid ua talitonuina taofia le fefete, suia, siama.Undissociated sulfite ua lipotia mai e 1000 taimi sili atu le malosi nai lo bisulfite i le taofiofia E. coli. E 100-500 taimi malosi i fefete pia ma 100 taimi malosi atu e suia. A o le sulfur dioxide e oona, e sili ona malosi lona aafiaga i le aveina o meaola niniʻi.
3, Galue o loosening sui sooupu
Mafai ona faʻaaogaina o ni vaega o le soʻona tatalaina sooupu.
3) Antioxidant aafiaga.
Sulphite ei ai sona ofoofogia aafiaga faʻamamaina. Ona o le sulfurous acid o se malosi faʻaititia sooupu, e mafai ona faʻaumatia le okesene i fualaʻau ma fualaʻau faʻalapotopotoga, taofia le gaioiga o oxidase, o le faʻamamaina oxidation o vaitamini C i le puipuia o fualaʻau ma fualaʻau e sili ona aoga.

Faʻavaeina o gaioiga o le sodium metabisulfite:

O le faʻamamaina e tusa ma lona ituaiga gaioiga e mafai ona vaevaeina i ni vaega se lua: O le faʻamaʻaina o le faʻamaʻaina o le toto ma le faʻaititia o le faʻamaʻimauina.

Sodium metabisulfite mafai ona faʻapipiʻiina e ala i le faʻaititia o pigment. O le lanu o le tele o meaola tuʻufaʻatasi na mafua mai i le chromaticity kulupu o loʻo i totonu o a latou molemole. O kulupu kulupu kulupu aofia ai unsaturated noataga, faʻaititia o le faʻamamaina faʻamamagoina hydrogen atoms mafai ona faia lauulu lanu kulupu aofia ai i le unsaturated fusia i totonu o le nofofua sootaga, meaola o le a leiloa lanu. O nisi meaʻai Browning e mafua mai ile iai o ferric ions, faʻaopopo le faʻaititia o le paʻepaʻe e mafai ai ona faʻasuaʻi ai ioni i niʻi uila, puipuia le faʻalanuina o meaʻai.

Sodium metabisulfite ua faʻapaina i le faʻaopopoina o sulfites. Anthocyanin ma suka e mafai ona faʻapaʻepaʻeina e ala i le faʻaopopoina o uiga. O lenei tali e mafai ona toe faʻafoʻi, ma e mafai ona aveʻese le sulfurous acid e ala i le faʻavevela poʻo le faʻavaivaia, ina ia mafai ai ona toefaʻafouina le anthocyanin ma mafai ai ona toe faʻaleleia lona lanu mumu muamua

I le pisinisi masi, sodium metabisulfite o loʻo faʻaaogaina o se masi keke faʻaleleia atili. Ae le i faʻaaogaina, ua sauni i le 20% fofo, ona faʻaopopo ai lea i totonu o le paluga matua i taimi eseese i le taimi o paluga gaosi auala. Ona o le sulfur dioxide faʻasaʻolotoina e le sodium pyrosulphate i le faʻagasologa o paluga sauniuniga, le malosi ma le maʻaʻa o le falaoamata pulapula. e lapoʻa tele, ma o se aofaʻi laʻititi o faʻaopopoga mafai ona taofia le deformation o oloa masi ona o le soona malosi.Tough paluga mafai ona faʻaopopoina e tusa ai ma le malosi o le falaoamata, ma masani ai i le maualuga vaega o le suauʻu ma suka suka paluga paluga paluga manaia. i le mea e gata ai le mafai ona faʻaaogaina, o le mafuaʻaga ona o le faʻaopopoina o le suauʻu ma le suka lava ia na taofia ai le faʻateleina o le faʻaaogaina o le suavai o le gluten protein, puipuia ai le faʻatulagaina o le tele o gluten, leai se mea e faʻaopopo ai le sodium metabisulfite.

Manatu mo le faʻalogo i le faʻaaogaina o sodium metabisulfite:

O mea nei e tatau ona maitauina pe a faʻaaogaina le sodium metabisulfite i mea gaosi meaʻai:
1) sodium metabisulfite reductive bleaching agents, o lona tali e le mautonu ma le mautonu, ua faʻaaogaina nei, e puipuia ai le faʻatutuina o le sulfite ma le faʻapalapalaina.
2) pe a iai uamea uʻamea i meaʻai, e mafai ona faʻamamaina le totoga o le sulfite; E mafai foi ona faʻaititia le faʻaitiitia o le faʻamamaina o le pigment pigment, ma faʻaititia ai le aoga o le vailaʻau. O le mea lea, o chelators uʻamea o loʻo faʻaaogaina foi i le taimi o gaosiga.
3) o le faʻaaogaina o le sulfite totoga mea, ona o le leiloa o le sulfur dioxide ma faigofie lanu, o lea e masani ai i le meaai toega ova sulfur dioxide, ae o le toe aofaʻi le tatau ona sili atu i le tulaga masani
4) Sulphuric acid e le mafai ona taofia le gaioiga o pectinase, lea o le a faʻaleagaina ai le tuʻufaʻatasia o pectin. I se faʻaopopoga, sulfurous acid infiltration i totonu o le fualaʻau fualaʻau, o le faʻagaioiga o fualaʻau fualaʻau, ina ia aveʻese uma sulfur dioxide, o lea o le fualaʻau faʻasaoina ma sulfurous acid e naʻo le talafeagai e fai ai jam, fualaʻau mago, fualaʻau uaina, candied fualaʻau, e le mafai ona faʻaaogaina o mea masani mo apa.
5) E mafai e Sulfites ona faʻaleagaina le thiamine, o lea e le faigofie ai ona faʻaaogaina i meaʻai iʻa.6) E faigofie ona tali atu le sulfites ile aldehydes, ketones, proteins, ma isi.

Faiga masani ma Atinaʻe:

I le aso nei gaosi meaʻai gaosi, aua o meaʻai i nisi taimi e maua ai le manaʻomia lanu, poʻo ni meaʻai masani mea ona o le eseese, felauaiga, teuina metotia, pikiina vaitaimi o le matua, o le lanu e eseʻese, lea e ono taʻitaʻia ai le mulimuli oloa oloa e le tumau ma aʻafia ai le lelei o meaʻai. O le mea lea, i aso nei sili atu ma sili atu ona uaʻi atu i le lelei o meaʻai, o le atinaʻeina o le meaʻai mea faʻapapaina meaʻai e le faʻatapulaʻaina, o le mea moni, o se ituaiga o meaʻai mea faʻapipiʻiina meaʻai, o le atinaʻeina o le sodium metabisulfite e sili foi. metabisulfite ei ai le tele o ituaiga o gaioiga, e le gata i le matafaioi o le faʻapaʻepaʻeina, ae faapea foi le matafaioi o le faʻamamaina o le tino, o le matafaioi o le puipuia o le enzyme Browning, o le matafaioi a le antisepsis, o lona auala e gaosi ai e faigofie ma faigofie, o lea i le tulaga e mautinoa ai le saogalemu o meaʻai. , sodium metabisulfite atinaʻe avanoa e telē tele.
