Nekuvandudzwa kwedanho rehupfumi hwenyika, danho resainzi uye tekinoroji, uye ruzivo rwehutano, "girinhi" uye "zvakasikwa" zvekudya zvakabuda sezvinodiwa nenguva, uye zvakacherechedzwa nekugamuchirwa neveruzhinji.Indasitiri yezvipfuyo iri kuwedzera uye kukura, uye vanoda mhuka dzinovaraidza vanoona mhuka dzinovaraidza seimwe yenhengo dzemhuri.Mazwi akadai sekuti "zvakasikwa", "girinhi", "yekutanga" uye "organic" ave mamiriro ekunze ekuti vanhu vasarudze zvigadzirwa zvemhuka.Vanhu vanonyanya kunetseka nezvehutano hwemhuka kupfuura mitengo yezvigadzirwa zvemhuka.Nekudaro, vazhinji vatengi havana kujeka nezve kunaka uye maitiro e "zvakasikwa" chikafu chemhuka.Ichi chinyorwa chinopfupisa zvachinoreva uye maitiro.
1.Chirevo chepasi rose che "zvakasikwa" chikafu chemhuka
"Natural" ishoko rinowanzoonekwa pamabhegi ekurongedza echikafu chepasi rose chemhuka dzemhuka.Kune dudziro dzakawanda dzeizwi iri, uye dudziro yeshoko remukati ndeye "zvakasikwa"."Natural" inowanzonzi inoreva nyowani, isina kugadziridzwa, isina kubva kune yakawedzera kuchengetedza, zvinowedzera uye zvigadzirwa zvekugadzira.IAmerican Association for Feed Control (AAFCO) inobvumira chikafu chemhuka kuti chinyorwe se "chisikigo" kana chichingotorwa kubva mumiti, mhuka kana zvicherwa, chisina chero chekuwedzera, uye chisati chaitwa kemikari synthesis processing.Tsanangudzo yeAAFCO inoenderera mberi ichiti "chikafu chechisikigo" chikafu chisina kugadziriswa kana kugadziriswa ne "kugadzirwa kwemuviri, kudziyisa, kudhirowa, kucheneswa, kuisa pfungwa, kupera simba, enzymatic hydrolysis, kana kuvirisa."Naizvozvo, kana mavhitamini akagadzirwa nemakemikari, mamineral kana trace elements akawedzerwa, chikafu chinogona kuramba chichinzi "chikafu chechipfuwo chechisikigo", se "chikafu chechipfuwo chechisikigo chine mavhitamini akawedzerwa nemaminerari".Izvo zvakakosha kuti tizive kuti tsananguro yeAAFCO ye "zvakasikwa" inongotaura maitiro ekugadzira uye haina chirevo chekutsva uye kunaka kwechikafu chemhuka.Huku dzehuku dzisina kunaka, huku dzisina kukodzera kudyiwa nevanhu, uye magiredhi akaipisisa ehuku yehuku achiri kusangana neAAFCO maitiro e "chikafu chechisikigo."Rancid mafuta achiri kusangana neAAAFCO maitiro e "chikafu chechipfuyo chepanyama," sezviyo zvine mold uye mycotoxins.
2. Regulations pazvichemo zve "zvakasikwa" mu "Pet Feed Labeling Regulations"
"Pet Feed Labeling Regulations" inoda: Semuyenzaniso, zvese zvekudya mbishi uye zvekuwedzera zvekudya zvinoshandiswa muzvigadzirwa zvekudya zvemhuka zvinobva kune zvisina kugadziriswa, zvisiri zvemakemikari process process kana chete kuburikidza nekugadzirisa kwemuviri, kupisa kwemafuta, kudhirowa, kucheneswa, hydrolysis, enzymatic hydrolysis, kuvirisa Kana chirimwa, mhuka kana mineral trace elements inogadziriswa nekuputa uye mamwe maitiro anogona kuita hunhu pachigadzirwa, vachiti "zvakasikwa", "zviyo zvechisikigo" kana mazwi akafanana anofanira kushandiswa.Semuyenzaniso, kana mavhitamini, maamino acids, uye mamineral trace elements akawedzerwa muzvigadzirwa zvekudyisa zvipfuyo akagadzirwa nemakemikari, chigadzirwa chinogona zvakare kunzi "chezvakasikwa" kana "chikafu chechisikigo", asi mavhitamini, amino acids, uye zvicherwa zvinoshandiswa zvinofanirwa. kuongororwa panguva imwe chete.Trace elements zvakanyorwa, zvichireva kuti mazwi ekuti "zvakasikwa zviyo, zvakawedzerwa neXX" zvinofanira kushandiswa;kana maviri (makirasi) kana anopfuura maviri (makirasi) emakemikari akagadzirwa mavhitamini, amino acids, uye mineral trace elements akawedzerwa, chikafu chinogona kushandiswa mukuda.Zita rekirasi rekuwedzera.Semuenzaniso: "zviyo zvechisikigo, zvine mavhitamini akawedzerwa", "zviyo zvechisikigo, zvine mavhitaminzi akawedzerwa uye amino acids", "mavara echisikigo", "kuchengetedza zvisikwa".
3. Preservatives mu "natural pet food"
Musiyano chaiwo pakati pe "chikafu chechipfuwo chekudya" uye zvimwe zvikafu zvechipfuyo zviri mumhando yezvidziviriro zvavanazvo.
1) Vitamin E yakaoma
"Vitamin E yakaoma" musanganiswa we beta-vitamin E, gamma-vitamin E, uye delta-vitamin E inoshandiswa kuchengetedza chikafu chemhuka.Haisi yekugadzira, inochengetedza zvisikwa, uye inotorwa kubva muzvinhu zvakasikwa.Iyo inobvisa inogona kuwanikwa nenzira dzakasiyana-siyana: kudhirowa doro, kugeza uye distillation, saponification kana mvura-yemvura kubviswa.Naizvozvo, vhitamini E yakaoma inogona kuiswa muchikamu chezvakasikwa zvekuchengetedza, asi hapana vimbiso yekuti inotorwa kubva kune zvakasikwa mbishi zvinhu.Vitamin E yakaoma inogona kushandiswa chete kuchengetedza uye haina biological chiitiko mumbwa, asi a-vitamini haina chekuchengetedza maitiro uye ine chete biological chiitiko mumuviri.Naizvozvo, AAFCO inoreva a-vitamin E sevhitamini uye inoisa mavhitaminzi kunze kwe-vitamin E semakemikari anochengetedza.
2)Antioxidants
Kuti udzivise kuvhiringidzika kwemafungiro, pfungwa ye "antioxidant" yakatorwa.Vhitamini E uye zvinodzivirira zvino zvave zvakabatana kunzi antioxidants, kirasi yezvigadzirwa zvinononoka kana kudzivirira oxidation.Active vhitamini E (a-vitamin E) inoshanda se antioxidant mukati memuviri, ichidzivirira oxidation yemasero uye tishu, nepo inochengetedza yepanyama (vitamin E yakaoma) inoita se antioxidant mukudya kwemhuka, kudzivirira kukuvadzwa kweoxidative kune pet food ingredients.Synthetic antioxidants inowanzo tenda kuti inoshanda zvakanyanya mukuchengetedza kugadzikana kwechikafu chemhuka.Iwe unofanirwa kuwedzera 2 nguva yehuwandu hwemasikirwo antioxidants kuti uwane mhedzisiro yakafanana seyakagadzirwa antioxidants.Naizvozvo, synthetic antioxidants ine zvirinani antioxidant mabasa.Nezve chengetedzo, zvinoshumwa kuti ese ari maviri echisikigo antioxidants uye ekugadzira antioxidants ane mamwe maitiro asina kunaka, asi akakodzera tsvakiridzo mishumo yese inotorwa nekudyisa nhamba huru yemhuka dzekuyedza.Pakave pasina mishumo yekuti kudya zvakawandisa zvakasikwa kana zvekugadzira antioxidants kune zvakanyanya kuipa pahutano hwembwa.Zvimwe chetezvo ndezvechokwadi nezvecalcium, munyu, vhitamini A, zingi, uye zvimwe zvinovaka muviri.Kunyanya kushandiswa kunokuvadza kuhutano, uye kunyange kunyanya kushandiswa kwemvura kunokuvadza kumuviri.Zvinonyanya kukosha, basa rema antioxidants nderokudzivirira mafuta kuti asaende, uye nepo kuchengetedzwa kwemaoxidants kuri kukakavara, hapana kupokana kuti maperoxide aripo mumafuta ane rancid anokuvadza hutano.Peroxides mumafuta ane rancid anokuvadzawo mavhitaminzi anonyungudika mumafuta A, D, E uye K. Kuita kwakashata kuzvokudya zverancid kunonyanya kuwanda mumbwa pane zvisikwa kana zvekugadzira antioxidants.
