Basa reCitric Acid muChikafu
Citric acid ndeimwe yezvinowedzerwa zvekudya zvinowanikwa muzvigadzirwa zvakasiyana-siyana zvekudya nezvinwiwa. Inozivikanwa zvakanyanya nekuravira kwayo kunozorodza uye inovava uye inoita basa rakakosha mukuchengetedza mhando yechigadzirwa. Kupfuura kuravira kwayo kwakasiyana, citric acid ine mabasa akawanda muhunyanzvi hwezvekudya, kubva pakugadzirisa acidity kusvika pakubatsira kuwedzera nguva yekugara kwayo. Nekuda kwekushandiswa kwayo kwakasiyana-siyana uye kuchengetedzeka kwayo kana ikashandiswa sezvakarairwa, citric acid ndiyo sarudzo huru muindasitiri yezvekudya yemazuva ano.
Chii chinonzi Citric Acid?
Citric acid iasidhi yeorganic inowanikwa mumichero yakawanda, kunyanya michero yecitrus yakaita semarimu, marimu, uye maranjisi. Muindasitiri, citric acid inowanzo gadzirwa kuburikidza nemaitiro ekuvirisa uchishandisa tupukanana (semuenzaniso, Aspergillus niger) tunoshandura shuga kuita citric acid. Inowanzo wanikwa semakristaro machena kana hupfu, inonyungudika nyore nyore mumvura, uye ine kuravira kwakachena uye kunovava.
Muzvinyorwa zvezvinoshandiswa mukudya, citric acid inowanzo nyorwa se "citric acid" kana nekodhi yekuwedzera yechikafu E330. Kuvapo kwekodhi iyi kunoratidza kuti citric acid chinhu chinoshandiswa kwenguva refu uye chinoshandiswa zvakanyanya uye kushandiswa kwacho kunodzorwa munyika dzakawanda.
1. Mutongi weAcid
Basa guru re citric acid muchikafu nderekudzora acidity. Acidity (pH) inokanganisa zvakanyanya kuravira, magadzirirwo, ruvara, uye kugadzikana kwechikafu. Nekuwedzera citric acid, vagadziri vanogona kuderedza pH kuti vawane acidity inodiwa muzvigadzirwa.
Semuenzaniso, muzvinwiwa zvisina doro, majusi emichero, majamu, kana masosi, citric acid inobatsira kuwana chiyero chehunhu hunotapira, hune munyu, uye hunovava. Muzvigadzirwa zvinobva mumichero, citric acid inobatsirawo "kusimudzira" kunaka kwemuchero, zvichiita kuti uve mutsva uye wakapinza. Kugadziriswa uku kwepH kwakakosha nekuti kunyangwe musiyano mudiki mupH unogona kuchinja zvakanyanya kunaka kwemuchero.
2. Chinosimudzira Kunaka uye Chinogadzirisa Kunaka
Kunze kwekudzora pH, citric acid inoshandawo semuchina wekuwedzera kunaka, kunyanya kuwedzera kunzwa kutsva. Acid inopihwa necitric acid inowanzoonekwa se "yakachena" kupfuura mamwe maacid, zvichiita kuti ishandiswe zvakanyanya mumaswiti, majeli, zvinwiwa zveupfu, ice cream, yogati ine flavour yemichero, uye kunyange sprinkles.
Muzvinhu zvinotapira zvakaita semasiwiti kana zvinwiwa zvine flavour, citric acid inogadzira musiyano unofadza nekuravira kunotapira. Musanganiswa uyu wesweet-sour unogadzira "mhedzisiro inozorodza" inoita kuti chigadzirwa chive chakareruka uye chisina kunaka. Nekuda kweizvi, citric acid inozivikanwa mumaswiti anonaka, gummies, uye zvinwiwa zvine flavour yeorenji.
3. Zvidziviriro Zvisina Kunanga Pakuburikidza Nekudzikisa pH
Citric acid haisi mushonga unochengetedza zvinhu "zvakananga" se sodium benzoate kana potassium sorbate, asi inobatsira kuchengetedza zvinhu zvisina kunanga nekuderedza pH. Mazhinji mabhakitiriya anoora uye anokonzera zvirwere anonetseka kukura mumamiriro ezvinhu ane acid. Nekuderedza pH yezvikafu, citric acid inogona kunonoka kukura kwemamwe mabhakitiriya, zvichibatsira kuti zvigadzirwa zvigare kwenguva refu.
Muzvikafu zvakaita semuto wematomatisi, muto wechiri wakabikwa mumabhodhoro, zvinwiwa zvemichero, nezvimwe zvigadzirwa zvemumagaba, kuisa acid ne citric acid kunogona kuva chikamu chehurongwa hwekudzora hutachiona. Mumabasa emaindasitiri, citric acid inowanzo sanganiswa nedzimwe nzira dzakadai se pasteurization, sterilization, kana kushandisa zvimwe zvinochengetedza kuti pave nemhedzisiro inoshanda.
4. Antioxidant uye Color Stabilizer (Chelating Agent)
Rimwe remabasa akakosha e citric acid nderekuchekerera, zvichireva kuti inogona kusunga ma ions esimbi akadai sesimbi nemhangura. Ma ions aya esimbi anogona kukurumidzisa maitiro e oxidation anokonzera rancidity, shanduko yeflavour, kana kuchinja ruvara rwechikafu.
Nekubatanidza maayoni esimbi, citric acid inobatsira kuderedza oxidation. Mhedzisiro yayo inoonekwa muzvigadzirwa zvakaita semafuta, margarine, zvinwiwa, uye zvigadzirwa zvemichero. Citric acid inobatsirawo kuchengetedza ruvara rwechikafu, senge michero yakachekwa kana zvigadzirwa zvinobva mumichero, nekudzivirira kukurumidza kusviba nekuda kwe oxidation reactions.
5. Inodzivirira kusviba kwemichero nemiriwo
Michero yakaita semaapuro, mapeya, nemaavocado inowanzo sviba mushure mekuchekwa nekuda kwekuita kwema enzyme. Mishonga yeCitric acid inowanzo shandiswa kunyikisa michero yakachekwa kuti irambe iine ruvara rwakajeka kwenguva refu. Kuwedzera kweacidity kunogona kunonotsa mashandiro ema enzymes anokonzera sviba, ukuwo zvichideredza oxidation.
Mumba, basa iri rakafanana nekushandisa muto weremoni pamuchero wakachekwa. Musiyano ndewekuti citric acid muchimiro cheupfu inopa simba risingaperi uye iri nyore kudzora pakukora.
6. Inobatsira Kuumbwa kweGel muPectin Products
Pakugadzira jamu, marmalade, kana jeli, kubudirira kwekuumbwa kwejeli kunokonzerwa zvikuru nepH. Pectin—fiber yechisikigo inogadzira jeli—inoda mamiriro chaiwo easidhi kuti igadzire network yejeli zvakanaka. Citric acid inobatsira kudzikisa pH kusvika padanho rakakodzera, zvichikonzera kuti jamu rive rakakora uye rakagadzikana.
Kana pasina acidity yakakwana, jamu rinogona kuyerera zvakanyanya, kuoma kurikora, kana kuva nemaumbirwo akasiyana. Nokudaro, citric acid inowanzova chinhu chakakosha, kunyanya kana muchero unoshandiswa uine acid shoma yechisikigo.
7. Wedzera Kushanda Kwezvimwe Zvinochengetedza
Mimwe mishonga yekuchengetedza inoshanda zvakanyanya kana pH yakaderera. Nekuderedza pH ne citric acid, vagadziri vanogona kuwedzera kushanda kwemishonga yekuchengetedza yakaita se benzoates kana sorbates, zvichiita kuti pave nedosi inoshanda zvakanyanya ukuwo ichisangana nezvinodiwa zvekuchengetedza chikafu.
Izvi zvinowanzoitika muzvinwiwa, masosi, uye zvigadzirwa zvakagadzirira kudyiwa zvinoda kugadzikana kwezvipenyu kwenguva yakareba. Kudzora pH inzira yakakosha yekuchengetedza kuchengetedzeka uku uchichengetedza kunaka.
8. Mashandisirwo muZvigadzirwa Zvakasiyana-siyana zveChikafu neZvinwiwa
Nekuda kwemabasa ayo akasiyana-siyana, citric acid inoshandiswa mumhando dzakasiyana dzezvigadzirwa, zvinosanganisira:
1. Zvinwiwa: zvinwiwa zvisina doro, zvinwiwa zvemichero, sirapu, zvinwiwa zvine hupfu.
2. Masiwiti nezvikafu zvishoma: masiwiti anovava, gummy, zvinonhuhwirira zvinovava.
3. Zvigadzirwa zvemichero: jamu, jeli, michero yakakangwa, michero yakachekwa yakagadzirira kudyiwa.
4. Masosi nezvinonhuwira: muto wematomatisi, muto wechiri, saradhi yekudyisa.
5. Zvigadzirwa zvemukaka: yogati ine flavour yemichero, zvinwiwa zvemukaka zvine flavour (muhuwandu hwakarongwa).
6. Zvigadzirwa zvakagadzirwa: zvekudya zvemumagaba nezvimwe zvekudya zvakagadzirira kudyiwa zvinoda kugadziriswa kwepH.
Miganhu Yekuchengetedza uye Kushandisa
Kazhinji, citric acid inoonekwa seyakachengeteka kuvanhu vazhinji kana ikashandiswa sezvakarairwa. Inowanikwawo muzvikafu zvezuva nezuva, kunyanya michero. Zvisinei, kunwa zvakanyanya zvinhu zvine acid yakawanda kunogona kukonzera zviratidzo kune vamwe vanhu, zvakaita sekutsamwa mudumbu, kusagadzikana kwemazino (sezvo acidity ichigona kuparadza enamel kana munhu achigara achiona), kana maronda mumuromo kune vanhu vane hanya.
Saka, vagadziri vezvekudya vanotevedzera mitemo yekushandiswa kwezvekudya yakaiswa nemasangano anotonga zvekudya munyika imwe neimwe. Pamhuri, citric acid inofanira kushandiswa zvishoma uye kugadziriswa kuti ienderane nezvinodiwa neresipi yacho.
Penutup
Citric acid inoita basa guru muindasitiri yezvikafu nezvinwiwa nekuda kwemabasa ayo akawanda. Haingopi chete kuravira kunozorodza uye kunovava asiwo inobatsira kudzora pH, kudzikamisa ruvara, kunonoka oxidation, kutsigira kuumbwa kwepectin gel, uye inobatsira kuti igare kwenguva refu nekudzora acidity. Kana ikashandiswa nemazvo, citric acid inobatsira kugadzira chikafu chakasimba, chakachengeteka, uye chine kuravira kwakafanana. Hazvishamisi kuti chinhu ichi chinhu chakakosha mune zvakawanda zvezvigadzirwa zvekudya zvatinodya zuva rega rega.
