(1) Nguva yekuwedzera
Iyo inogona kuoneka kubva kune mashandiro e antioxidants kuti antioxidants inogona kungotadzisa lipid oxidation.
Kunonoka iyo nguva iyo chikafu chinotanga kukanganisa, asi haigone kushandura mhedzisiro yezvakatoparadzwa, saka antioxidants inofanira kuwedzerwa nekukurumidza sezvinobvira. Zvinonzi kuwedzera antioxidants (BHA uye BHT) mukubika kwemafuta maitiro kunoshanda zvakanyanya.
Vegetable mafuta vacuum deodorization inhanho yekupedzisira mukugadzirisa oiri. Sezvo phenolic antioxidants inotyisa pasi pemamiriro ekubvisa mafuta, inofanira kuwedzerwa pasi pemamiriro echando, kana mushure mokunge mafuta akasvibiswa akaputirwa kune tangi yekuchengetedza Wedzera antioxidants.
Zvokudya zvakakangwa zvinowanzotora mafuta akawanda. Nokudaro, mafuta matsva anofanira kuramba achiwedzerwa kune fryer. Panguva imwecheteyo, maoxidants matsva anounzwawo kutsiva kurasikirwa kunokonzerwa nemhepo distillation. Kazhinji wedzera methyl polysiloxane (Methy1 polysi1oxane) pazasi 10mg/kg mumafuta ekukangwa. Kunyange zvazvo isiri antioxidant, haina mhedzisiro yakananga pakugadzikana kwechigadzirwa chekupedzisira, asi inogona kuumba insoluble pamusoro pemafuta. Iyo firimu inodzivirira mafuta kuti asaonekwe kumhepo, nokudaro achidzivirira mafuta anopisa panguva yefrying process.
(2) Kushandiswa kwakakodzera
Kusiyana nemapreservatives, huwandu hwema antioxidants akawedzerwa haawanzo hukama hwakanaka neiyo antioxidant mhedzisiro. Kana imwe fungidziro yakapfuudzwa, kwete chete haisati ichiwedzera iyo antioxidant mhedzisiro, asi ine mhedzisiro yekusimudzira oxidation. Semuyenzaniso, tocopherol inogona kuburitsa yakanyanya kushanda padanho rakaderera, izvo zvakaenzana nekuisa kwayo mumafuta emuriwo asina kukora. Zvisinei, mune mamwe mamiriro ezvinhu, tocopherol ine oxidative effect, yakadai se-tocopherol. (TH2) Kana iyo yekumisikidza yakakwira, mahara radicals anoumbwa kukurudzira oxidation zvinoenderana nekutevera maitiro:
ROOH TH2 ==== RO· TH· H2O
(3) Synergistic mhedzisiro ye antioxidants
Iko maviri kana anopfuura maoxidants anoshandiswa mukubatana, iyo antioxidant mhedzisiro inowanzove yakakura kupfuura huwandu hwekushandiswa kumwe chete. Ichi chiitiko chinonzi synergy ye antioxidants. Zvinowanzotendwa kuti izvi zvinodaro nekuti akasiyana antioxidants anogona kumisa ketani kuita kweoiri oxidation pamatanho akasiyana. Imwe synergistic mhedzisiro ndeyekuti iyo huru antioxidant inoshandiswa pamwe chete nemamwe antioxidants uye simbi ion chelating agents. Semuenzaniso, ascorbic acid inogona kushandiswa seyo huru antioxidant regenerating agent (electricity donor), oxygen scavenger, metal chelating agent, uye yayo oxidative browning Chigadzirwa chinewo antioxidant basa. Izvi zviviri zviri pamusoro apa zvinokonzeresa zvakaratidzwa mukuita uye zvinonyanya kushandiswa mukurwisa-oxidation yemafuta nemafuta.
(4) Kuparara uye kupararira
Iyo solubility ye antioxidants mumafuta inokanganisa iyo antioxidant mhedzisiro. Semuyenzaniso, mvura-soluble ascorbic acid inogona kushandiswa muchimiro chepalmitate yayo kudzivirira oxidation yemafuta. Oiri-soluble antioxidants kazhinji inoshandisa zvinotakura zvinonyungudutsa kuti zviasanganise mumafuta kana mafuta{{4}mune zvekudya. Izvi zvinonyungudutsa zvinonzi propylene glycol kana musanganiswa wepropylene glycol uye glycerol monooleate. Antioxidant inowedzerwa kumafuta akachena. Inogona kuwedzerwa zvakananga muchimiro chekugadzirisa kwakagadziriswa pasi pemamiriro ezvinhu anokurudzira (60 degree), uye inofanira kukurudzirwa kwenguva yakati pasi pemamiriro ekubvisa okisijeni kuti ave nechokwadi chokuti iyo antioxidant system inogona kuparadzaniswa zvakaenzana.
Paridza mumafuta ose.
