Nchito:
Sodium Metabisulfite ndichakudya chowonjezera chomwe chimagwiritsidwa ntchito. Kuphatikiza pa zotsatira zake zoyera, imakhalanso ndi izi:
1) Zotsatira za Anti Browning
Enzymatic Browning nthawi zambiri imapezeka mu zipatso, mbatata, Sodium Metabisulfite ndi yochepetsera, ntchito ya polyphenol oxidase imathandizira kwambiri, 00001% ya sulfure dioxide imatha kuchepetsa 20% ya michere, 0,001% ya sulfure dioxide imatha kuletsa ntchito ya enzyme, imatha kuletsa enzymatic Browning; Kuphatikiza apo, imatha kudya oxygen m'mitsempha yazakudya ndikusewera ndi deoxygenation. Sulfite pakuwonjezera kuchitapo ndi shuga, imalepheretsa shuga mu chakudya komanso amino acid glycoammonia reaction, motero imakhudza anti Browning.
2) Antiseptic zotsatira
Sulfurous acid itha kutenga gawo la asidi wololera, wosasakanikirana ndi sulfurous acid amakhulupirira kuti amaletsa yisiti, nkhungu, mabakiteriya.Ufissociated sulfite akuti ndiwopambana nthawi 1000 kuposa bisulfite poletsa E. coli. Ndi nthawi 100-500 yolimba kuposa yisiti ya mowa komanso kuwirikiza kawiri kulimba. Sulufure dioxide ikakhala ndi asidi, imakhala ndi mphamvu kwambiri ponyamula tizilombo.
3, Ntchito ya kumasula wothandizila
Itha kugwiritsidwa ntchito ngati zinthu zopangira kumasula.
3) Antioxidant zotsatira.
Sulfite imakhala ndi makutidwe ndi okosijeni odabwitsa chifukwa asidi a sulfurous ndi othandizira kwambiri, amatha kudya mpweya mu zipatso ndi masamba, amaletsa ntchito ya oxidase, kuwonongeka kwa mavitamini C poteteza zipatso ndi ndiwo zamasamba ndizothandiza kwambiri.
Limagwirira a zochita za metabisulfite ndi sodium:
Bleach malinga ndi momwe amagwirira ntchito atha kugawidwa m'magulu awiri: Makutidwe ndi okosijeni Bleach ndi Kuchepetsa Bleach.Sodium metabisulfite ndi njira yochepetsera kuyeretsa.
Mtundu wa mankhwala ambiri amachokera ku magulu a chromaticity omwe ali m'ma molekyulu awo.Magulu amtundu waubweya amakhala ndi maunyolo osakwaniritsidwa, kuchepetsa ma bleach kutulutsa maatomu a haidrojeni amatha kupanga gulu la tsitsi lomwe lili mumtanda wosasungika kukhala chomangira chimodzi, zinthu zakuthupi zimataya utoto. Chakudya china Browning chimayambitsidwa ndi kupezeka kwa ayoni oyamwa, kuwonjezera kuchepa kwa bulitchi kumatha kupanga ayoni wamafuta kukhala ma ayoni a ferric, kuteteza chakudya Browning.
Sodium metabisulfite imachapulidwa ndi kuwonjezera kwa ma sulfite. Anthocyanin ndi shuga zimatha kutsukidwa ndikuwonjezera kuchitapo kanthu. Izi zimasinthidwa, ndipo asidi wa sulfurous amatha kuchotsedwa ndi kutentha kapena acidification, kuti anthocyanin itha kusandulika ndipo mtundu wake woyamba wofiira ukhoza kubwezeretsedwanso.
Makampani opanga mabisiketi, metabisulfite ya sodium imagwiritsidwa ntchito ngati chosakanizira cha biscuit. Musanagwiritse ntchito, imakonzedwa mu 20% yankho, kenako imawonjezeredwa mu mtanda wosakhwima munthawi zosiyanasiyana pakupanga mtanda. Chifukwa cha sulfure dioxide yotulutsidwa ndi sodium pyrosulphate pokonza mtanda, mphamvu ndi kulimba kwa ufa wa gluten ndi yayikulu kwambiri, ndipo pang'ono pokha pokha imatha kuletsa kupindika kwa zopangira ma biscuit chifukwa champhamvu kwambiri.Mtanda wovuta ungawonjezeke molingana ndi mphamvu ya ufa, ndipo makamaka mgawo lalikulu la mafuta ndi shuga khirisipi mtanda ndi mtanda wotsekemera momwe ndingagwiritsire ntchito, ndichifukwa chakuti kuwonjezera kwa mafuta ndi shuga komweko kwalepheretsa kuwonjezeka kwamadzi kwamapuloteni a gluten, kulepheretsa kupangika kwa anthu ambiri a gluten, sipafunikira kuwonjezera metabisulfite ya sodium.
Zofunika kuzigwiritsa ntchito pogwiritsa ntchito metabisulfite ya sodium:
Mfundo zotsatirazi ziyenera kuzindikiridwa mukamagwiritsa ntchito metabisulfite ya sodium mu zakudya zopangidwa:
1) sodium metabisulfite redachingive bleaching agent, yankho lake ndi losakhazikika komanso losakhazikika, tsopano lagwiritsidwa ntchito, kupewa kusakhazikika kwa sulfite ndi volatilization.
2) pakakhala ayoni wazitsulo pachakudya, sulfite yotsalira imatha kupangidwanso oxidized; Itha kupangitsanso kuchepa kwa pigment makutidwe ndi okosijeni, potero amachepetsa mphamvu ya bleach.Choncho, ma chelators achitsulo amagwiritsidwanso ntchito popanga.
3) kugwiritsa ntchito zinthu zopangira sulfaite, chifukwa chakusowa kwa sulfure dioxide komanso mtundu wosavuta, nthawi zambiri muzakudya zotsalira za sulfure dioxide, koma zotsalira sizipitilira muyeso
4) Sulfuric acid silingalepheretse ntchito ya pectinase, yomwe ingawononge kulumikizana kwa pectin.Kuwonjezera apo, sulfurous acid kulowerera mu minofu yazipatso, kukonza zipatso zosweka, kuti athetse onse sulfure dioxide, chipatsocho chisungidwe ndi sulfurous acid ndiyabwino kokha kupanga kupanikizana, zipatso zouma, vinyo wazipatso, zipatso zotsekemera, sizingagwiritsidwe ntchito ngati zopangira zitini.
5) Sulfites amatha kuwononga thiamine, chifukwa chake sikophweka kugwiritsira ntchito chakudya cha nsomba. 6) Sulfites ndimosavuta kuyankha ndi aldehydes, ketoni, mapuloteni, ndi zina zambiri.
Zochitika ndi Kukula:
M'munda wamakono wokonza chakudya, chifukwa chakudyacho nthawi zina chimapanga mtundu wosafunikira, kapena zakudya zina zopangira chifukwa cha mitundu, mayendedwe, njira zosungira, nyengo yokhwima, utoto ndi wosiyana, womwe ungapangitse mtundu womaliza wazinthu kusasinthasintha komanso kumakhudza mtundu wa chakudya.Chomwecho, masiku ano chidwi cha chakudya masiku ano, chitukuko cha choyeretsera chakudya chilibe malire, zachidziwikire, monga mtundu wa choyeretsera chakudya, kukula kwa sodium metabisulfite ndiyonso yabwino. metabisulfite ili ndi ntchito zambiri, osati ntchito yokhayokha, komanso gawo la makutidwe ndi okosijeni, ntchito yoletsa Enzymatic Browning, ntchito ya antisepsis, njira yake yopangira ndiyosavuta komanso yosavuta, kotero pankhani yotsimikizira chitetezo cha chakudya , danga la metabisulfite la sodium ndi lalikulu kwambiri.
