Woyang'anira acidity: wokoma komanso wowawasa ndi ine

Kuti mupeze chakudya chamtundu wabwino, chakumwa, komanso chotsekemera, ndikofunikira kwambiri. Acidity regulator ndi mtundu wa wothandizila kununkhira, wotchedwanso wowuma wowawasa. Kuwonjezera zakudya zowawa ku chakudya kumatha kupatsa anthu chilimbikitso chotsitsimutsa, kuwonjezera njala, komanso kukhala ndi vuto linalake lothandizira.

Kawirikawiri amagawidwa mu acidic acid ndi organic acid. Mankhwala omwe amagwiritsidwa ntchito kwambiri ndi phosphoric acid, ndipo ma organic acid omwe amagwiritsidwa ntchito kwambiri ndi awa:asidi citric, lactic acid, acetic acid, tartaric acid, asidi wa malic, asidi fumaric, asidi ascorbic, gluconic acid, ndi zina.

Phosphoric acid imatha kulowa m'malo mwa citric acid ndi malic acid mumakampani opanga zakumwa, makamaka ngati wowawasa muzakumwa zopanda zipatso pomwe citric acid siyabwino. Itha kugwiritsidwa ntchito ngati pH yowongolera m'makampani opanga mowa, komanso ngati yankho la michere ya yisiti mufakitale yopanga yisiti yolimbikitsa kukula kwa ma cell a cell. Itha kugwiritsidwanso ntchito kuphatikiza ma antioxidants m'mafuta amanyama, ndipo itha kugwiritsidwa ntchito ngati chofotokozera cha sucrose madzi popanga shuga.

Citric acid imapezeka m'matumba ndi zinyama ndi mkaka, ndipo zipatso za citrus zimakhala ndi zambiri. Crystalline citric acid ndi yoyera poyera tinthu kapena ufa wonyezimira wonyezimira. Anhydrous citric acid ndimakristala opanda mtundu kapena ufa woyera, wopanda fungo komanso wopanda wowawasa. Citric acid ndiye wowuma wambiri wosunthika komanso wosunthika kwambiri. Ili ndi kusungunuka kwakukulu komanso kuthekera kwamphamvu kwa ma ayoni azitsulo. Kuphatikiza pa kugwiritsidwa ntchito ngati wowawasa pazakudya, citric acid imagwiritsidwanso ntchito ngati choteteza, antioxidant synergist, pH chosinthira, ndi zina zotero. Mlingo waukulu kwambiri ndi malinga ndi zosowa zachilengedwe, ndipo ADI ilibe malire.

Lactic acid idapezeka koyamba mu yogurt, chifukwa chake dzinali. Chakudya cha lactic acid (50%) chitha kugwiritsidwa ntchito ngati wowawasa mu zakumwa zozizilitsa kukhosi, zakumwa za yogurt, vinyo wopangira, viniga wosakaniza, msuzi wa soya wokometsera, zipatso, ndi zina zotero. zokometsera, komanso zimathandiza kupewa kukula kwa mabakiteriya.

Malic acid imapezeka m'maapulo, chifukwa chake dzinalo. Ili ndi kukoma kofewa komanso kosatha. Mwachidziwitso, amatha kusintha kwathunthu kapena makamaka asidi a citric omwe amagwiritsidwa ntchito pazakudya ndi zakumwa. Pansi pa kupeza zotsatira zomwezo, avareji mlingo wake ndi 8% -12% poyerekeza ndi citric acid (misa kachigawo). Makamaka, asidi ya malic imagwiritsidwa ntchito pazakudya zopatsa zipatso, zakumwa za kaboni, ndi zina zambiri, zomwe zitha kukonza kukoma kwa zipatso zake. Ku United States, malic acid amagwiritsidwa ntchito nthawi zonse pazakudya zatsopano. Kuchuluka kwake ndikulingana ndi zosowa zachilengedwe, ndipo ADI safuna malamulo apadera.

Kusunga: Lolani kuti nyengo zinayi zikhale zotetezeka komanso zoyambilira

Zosungitsa, monga dzinali likusonyezera, ndizowonjezera zakudya zomwe zimagwiritsidwa ntchito kusunga zakudya zowonongeka monga masamba, zipatso, ndi nyama. Chifukwa cha zoteteza, soseji ya ham, masoseji, nyama yophika yamzitini ndi zakudya zina zomwe zimagulitsidwa m'sitoloyo zimatha kukhalabe ndi kukoma kwanthawi yayitali; chifukwa choteteza, titha kudya mtunda wautali titanyamula kuchokera kumadera ena chaka chonse. Masamba atsopano ndi zipatso.

Zakudya zoteteza kudya zomwe zimakonda kugwiritsidwa ntchito zimaphatikizapo benzoic acid, butylhydroxyanisole ndi dibutylhydroxytoluene. Zina mwa izo, butyl hydroxyanisole ndichotetezera chabwino, ndipo sichili poizoni pamiyeso yokhazikika. Kuchuluka kwake kwa chakudya sikuyenera kupitirira 0,2 g / kg mwa mafuta. Mlingo wake ukakhala 0.02%, umaposa 0.01%. Mphamvu ya antioxidant yawonjezeka ndi 10%. Monga antioxidant wosungunuka mafuta, butylated hydroxyanisole ndioyenera zakudya zamafuta ndi zakudya zamafuta. Chifukwa chokhazikika bwino kwa matenthedwe, itha kugwiritsidwa ntchito pansi pa kukazinga kapena kuphika.

M'zaka zaposachedwa, kafukufuku wokhudza zoteteza zachilengedwe adakopa chidwi cha asayansi ochokera padziko lonse lapansi, ndipo kuchuluka kwa zinthu zachilengedwe zotetezedwa nthawi zambiri zimalandiridwa ndi anthu, monga tiyi polyphenols, vitamini E wachilengedwe, polylysine ndi chitosan.

Ponena za zipatso zomwe timagula pamoyo wathu watsiku ndi tsiku, akatswiri akuwonetsa kuti bola ngati mabizinesi azigwiritsa ntchito zoteteza moyenera, ogula sayenera kuda nkhawa ndi chitetezo.

Zosungitsa: onjezani mashelufu a chakudya

Zosungitsa zakudya zitha kulepheretsa tizilombo tating'onoting'ono, kuteteza chakudya kuti chisasokonezeke, potero chimakulitsa chakudya. Zakumwa zambiri ndi zakudya zopakidwa m'matumba zimafuna kusungidwa kwa nthawi yayitali, ndipo zotetezera chakudya nthawi zambiri zimawonjezedwa. Popeza zimakhudzana ndi thanzi la anthu, zoteteza zakudya ndizoletsedwa kwambiri pamitundu yonse yosungitsa.

dziko langa lavomereza zoposa 30 zololeza zotetezera chakudya, zonse zomwe zili ndi poizoni komanso wotetezeka. Asanavomerezedwe kuti agwiritsidwe ntchito, adachita zoyeserera zambiri, kuphatikizapo kuyesa kudyetsa ziweto, poyizoni ndi mayesero a poizoni ndikuzindikiritsa, ndipo zatsimikizika kuti sizipweteketsa thupi, kapena kuwononga thupi.

Kawirikawiri amagwiritsidwa ntchito ndi benzoic acid, sodium benzoate, asidi sorbic, potaziyamu sorbate, calcium propionate, etc. M'zaka zaposachedwa, zakudya zoteteza kuyambika zayamba kupanga njira zachitetezo, zakudya, komanso zopanda kuipitsa. Zatsopano zoteteza monga glucose, oxidase, protamine, lysozyme, mabakiteriya a lactic acid, chitosan, pectin kuwonongeka kwa zinthu, ndi zina zambiri. Ndipo amavomerezedwa kuti agwiritsidwe ntchito ndi boma.

M'malo mwake, bola ngati mitundu, kuchuluka ndi kuchuluka kwa zotetezera zakudya zomwe opanga chakudya adazisamalira mosamalitsa malinga ndi muyezo wadziko lonse "Makhalidwe Oyera Ogwiritsira Ntchito Zowonjezera Zakudya", sipadzakhala vuto lililonse paumoyo wa anthu, ndipo anthu akhoza kukhala otsimikiza kuti ndi odyetsedwa.

Mwachitsanzo, zakudya zomwe zimapezeka pamsika nthawi zambiri zimakhala ndi zoteteza monga potaziyamu sorbate ndi sodium benzoate. Izi zotetezera zomwe zimagwiritsidwa ntchito kwambiri nthawi zambiri zimatulutsidwa mumkodzo osati m'thupi mukamamwa thupi la munthu. Sonkhanitsani.

Ngati palibe zowonjezera zakudya

Ngati palibe antioxidants-

Zakudya zamafuta, kaya ndi mafuta achilengedwe a nyama ndi masamba kapena zakudya zokazinga, zimayambitsa kuchepa chifukwa cha makutidwe ndi okosijeni munthawi yochepa. Opanga atha kungowuma ndi kuwagulitsa. Ogulitsa amayenera kukonza mashelufu awo tsiku lililonse. Ogulitsa amataya chitetezo chawo. Kuyendetsa chakudya kuchokera kutali kudzakhalanso kosatheka.

Ngati palibe kukonzekera kwa enzyme-

Ma buns otentha omwe aku China amadya sadzakhala ofewa komanso okoma ngati lero. Anthu aku Europe amatha kudya buledi wolimba monga momwe adadyera ku Middle Ages. Zinthu zokha zomwe anthu padziko lapansi angadalire ndi mimba yawo asidi ndi malovu.

Ngati palibe chosangalatsa-

Masoseji a Ham, soseji, ndi nyama yophika zamzitini zidzasiya tebulo lathu, chifukwa kutayika kwa msuzi wapachiyambi pokonza kumapangitsa kuti uzimva ngati phula; nsomba, nkhanu ndi nsomba zina sizingakhutiritse anthu akumidzi, chifukwa mapuloteni adzatayika posungira kozizira. Kutaya madzi ndi kuzizira ndi kutaya kwachitsulo kwachuluka; Chomvetsa chisoni kwambiri ndikuti timataya madzi m'thupi ndipo sitimatha ngakhale kudya Zakudyazi pompopompo.

Ngati kulibe chakudya chokhazikika-

M'nyengo yotentha, ayisikilimu wathu wokondedwa adzaza ndi zotsalira za ayezi mufiriji. Ndizomvetsa chisoni kudya ngati madzi oundana; ndichisoni kutaya; mkaka wa koko, mkaka wa zipatso, mkaka wosawilitsidwa, yogurts osiyanasiyana, mkaka wogwira ntchito, ndi zina zambiri. Sangaledzere, ngakhale mkaka padambo nthawi zonse umafinya.

Ngati palibe emulsifier——

Zodabwitsa mkaka ndi madzi wosanjikiza zochitika mu zakumwa. Shuga wazopangidwa ndi chokoleti ndiosavuta kuwumitsa, buledi sichosavuta kusunga, margarine ndi zakudya zamzitini zimasiyanitsidwa ndi mafuta ndi madzi, ndipo toffee ndi bubble chingamu ndizosavuta kuzimata ndikumamatira mano.

Ngati palibe chotupitsa-

Ma buns otentha omwe amakondedwa ndi akumpoto sangafune kusiya, ndipo makeke omwe anthu akumwera amakonda kunena. Anthu mdziko lonselo akuyenera kutsazika ndi timitengo tomwe takhala tikudya kwa zaka zoposa 900.

Mwachidule, ngati kulibe zowonjezera zowonjezera, sipadzakhala mafakitale apamwamba amakono azakudya, ndipo sipadzakhalanso moyo wamakono wapamwamba.
