Nhau dzeKambani Chigadzirwa Chitsva Glucono-delta-lactone

Chigadzirwa Chitsva Glucono-delta-lactone
Colourkem yakatanga itsva Chikafu Yekuwedzera: Glucono-delta-lactone musi wa20.Chikunguru, 2022. Glucono-delta-lactone yakadimburirwa selactone kana GDL, uye formula yayo yemamorekuru inoti C6Hl0O6.Toxicological bvunzo dzakaratidza kuti isiri-chepfu inodyiwa chinhu.White crystal kana white crystalline powder, inenge isinganhuhwi, inotanga kutapira yozovava mukuravira.soluble mumvura.Glucono-delta-lactone inoshandiswa se coagulant, kunyanya pakugadzirwa kwe tofu, uyewo seprotein coagulant yezvigadzirwa zvemukaka.

Principle
Nheyo yeglucoronolide coagulation ye tofu ndeyokuti kana lactone yanyungudutswa mumvura kuita gluconic acid, asidhi ine acid coagulation effect paprotein mumukaka wesoya.Nekuda kwekuparara kwelactone kuri kunonoka, iyo coagulation reaction inofanana uye kushanda kwayo kwakakwira, saka iyo yakagadzirwa tofu yakachena uye yakapfava, yakanaka mukuparadzaniswa kwemvura, inoshingirira kubika nekukacha, inonaka uye yakasarudzika.Kuwedzera mamwe macoagulants akadai se: gypsum, brine, calcium chloride, umami seasoning, nezvimwewo, inogonawo kugadzira tofu yakasiyana-siyana.

Shandisa
1. Tofu coagulant
Uchishandisa glucono-delta-lactone seprotein coagulant kugadzira tofu, magadzirirwo acho akachena uye akapfava, pasina kuvava uye astringency yechinyakare brine kana gypsum, hapana kurasikirwa kweprotein, goho rakawanda re tofu, uye nyore kushandisa.
Tichifunga nezvenyaya yekuti kana GDL ichishandiswa yoga, tofu ine kuvira zvishoma, uye kuvava kunonaka hakukodzere tofu, saka GDL neCaSO4 kana mamwe macoagulants anowanzoshandiswa pamwe chete mukugadzira tofu.Maererano nemishumo, kana uchigadzira pure tofu (kureva nyoro tofu), chiyero cheGDL/CaSO4 chinofanira kunge chiri 1/3-2/3, huwandu hwekuwedzera hunofanira kuva 2.5% yehuremu hwebhinzi yakaoma, tembiricha inofanira kudzora 4 °C, uye goho re tofu rinofanira kuoma.5 yakapetwa kurema kwebhinzi, uye kunaka kwakanaka zvakare.Nekudaro, kune mamwe matambudziko anofanirwa kucherechedza kana uchishandisa GDL kugadzira tofu.Semuenzaniso, kuoma uye kutsenga kwe tofu yakagadzirwa kubva kuGDL haina kunaka seyechinyakare tofu.Mukuwedzera, huwandu hwemvura yekugeza hushoma, uye puroteni mubhinzi yebhinzi inorasika zvakanyanya.

2. Mukaka gelling agent
GDL haingoshandiswi seprotein coagulant yekugadzira tofu, asiwo seprotein coagulant yemukaka weprotein kugadzirwa kweyoghurt nechizi.Zvidzidzo zvakaratidza kuti gel simba remukaka wemhou rakagadzirwa ne acidification neGDL kaviri kune yemhando yekuvirisa, nepo simba rembudzi yogati gel rakagadzirwa neacidification neGDL ka8-10 kune yemhando yekuvirisa.Vanotenda kuti chikonzero chekushaya simba kwegel yeyogati yakaviriswa inogona kunge iri kukanganiswa kwezvinhu zvekutanga (biomass uye cellular polysaccharides) pakusangana kwegel pakati pemapuroteni panguva yekuvirisa.Zvimwe zvidzidzo zvakaratidzawo kuti gel remukaka rinogadzirwa ne acidification yekuwedzera 3% GDL pa 30 °C ine chimiro chakafanana nejeri rinogadzirwa nelactic acid bacteria fermentation.Zvinonziwo kuwedzera 0.025% -1.5% GDL kumukaka wenyati inogona kuwana inodiwa curd pH, uye iyo chaiyo yekuwedzera inosiyana nemafuta emukaka wenyati uye tembiricha yekukora.

3. Kuvandudza unhu
Kushandiswa kweGDL mukudya kwemasikati uye nyama yenguruve yekakani inogona kuwedzera mhedzisiro yemuiti wemuvara, nekudaro ichidzikisa huwandu hwenitrite, iyo inonyanya kutyisa.Nokuda kwehutano hwezvokudya zvemumagaba, iyo yakawanda yekuwedzera mari panguva ino ndeye 0.3%.Zvave zvichishumwa kuti kuwedzerwa kweGDL pa4 ° C kunogona kuvandudza elasticity ye fibrillin, uye kuwedzerwa kweGDL kunogona kuwedzera kuwedzera kwejeri, kana pamberi pemyosin uye myosin kana pamberi pemyosin chete.simba.Mukuwedzera, kusanganisa GDL (0.01% -0.3%), ascorbic acid (15-70ppm) uye sucrose fatty acid ester (0.1% -1.0%) muhupfu inogona kuvandudza kunaka kwechingwa.Kuwedzera GDL kune zvakakangwa zvekudya zvinogona kuchengetedza mafuta.

4. Preservatives
Tsvakurudzo yeSaniea, marie-Helence et al.yakaratidza kuti GDL inogona pachena kunonoka uye inhibisa kugadzirwa kwephage ye lactic acid mabhakitiriya, nokudaro kuve nechokwadi chekukura uye kubereka kwelactic acid bacteria.Kuwedzera huwandu hwakakodzera hweGDL kumukaka kunodzivirira kusagadzikana kwephage mumhando yechigadzirwa chechizi.Qvist, Sven et al.akadzidza kuchengetedza zvinhu zveGDL mumasoseji makuru matsvuku, uye akawana kuti kuwedzera 2% lactic acid uye 0.25% GDL kune chigadzirwa kunogona kutadzisa kukura kweListeria.Sausage hombe dzvuku dzakaiswa jekiseni neListeria dzakachengetwa pa10 ° C kwemazuva makumi matatu neshanu pasina kukura kwebhakitiriya.Samples isina preservatives kana sodium lactate chete yakachengetwa pa10 °C uye mabhakitiriya aizokura nekukurumidza.Zvisinei, zvakakosha kuziva kuti kana huwandu hweGDL hwakanyanya, vanhu vanogona kuona kunhuwa kunokonzerwa nayo.Zvinonziwo kushandiswa kweGDL uye sodium acetate muchiyero che 0.7-1.5: 1 inogona kuwedzera hupenyu hwesherufu uye kutsva kwechingwa.

5. Acidifiers
Se acidulant, GDL inogona kuwedzerwa kune inotapira sherbet uye jelly senge vanilla inobvisa uye chokoreti banana.Ndicho chinhu chikuru chine acidic mumusanganiswa wembiriso, inogona kuburitsa zvishoma nezvishoma carbon dioxide gasi, mabhuru anofanana uye akapfava, uye anogona kugadzira makeke ane zvinonaka zvakasiyana.

6. Chelating agents
GDL inoshandiswa sechelating agent muindasitiri yemukaka uye indasitiri yedoro kudzivirira kuumbwa kwelactite netartar.

7. Mapuroteni flocculants
Mune mapuroteni-ine maindasitiri emarara emvura, kuwedzera kweiyo flocculant inoumbwa necalcium munyu, magnesium munyu uye GDL inogona kuita kuti protein iwedzere uye inonaya, inogona kubviswa nemaitiro emuviri.

Zvekungwaririra
Glucuronolactone is white powdery crystal, inogona kuchengetwa kwenguva yakareba pasi pemamiriro ezvinhu akaoma, asi inosvibiswa nyore nyore kuva asidhi munzvimbo ine hunyoro, kunyanya mumvura ine mvura.Pakupisa kwekamuri, lactone mumushonga inosvibiswa zvishoma kuva asidhi mukati memaminitsi makumi matatu, uye tembiricha iri pamusoro pe65 degrees.Iko kumhanya kwehydrolysis kunokwidziridzwa, uye inozoshandurwa zvachose kuita gluconic acid kana tembiricha iri pamusoro pe95 degrees.Nokudaro, kana lactone inoshandiswa se coagulant, inofanira kunyungudutswa mumvura inotonhora uye inoshandiswa mukati mehafu yeawa.Usachengete mhinduro yayo ine aqueous kwenguva yakareba.
