Ma waena o nā mea?ai i ho?omo?a ?ia, nui ka ?aila a me nā huahana kuki he nui. ?O kekahi o kēia mau huahana he ha?aha?a ha?aha?a ha?aha?a loa, he li?ili?i ka hopena o ka ?elemakule i ko lākou ola mālama ?ana, a ?o ka rancidity o ka aila ke kumu nui e pili ana i kā lākou mālama pa?a.

Ma waho a?e o nā waiwai o ka?aila pono'ī, pili pono ka rancidity o ka?aila i ka mahana, ka mahana, ka ea, ka māmā, nā enzymes a me nā ion metala e like me ke keleawe a me ka hao i nā kūlana mālama.

I mea e ho?onui ai i ka pa?a o ka mālama ?ana o nā huahana, ho?ohui pinepine ?ia kekahi mau antioxidants i ka aila a i ?ole nā ????mea?ai i ?oi aku ka aila e ho?opane?e a pale i ka rancidity o ka aila, ?a?ole hiki ke ho?olō?ihi i ka manawa mālama a me ke ola o ka mea?ai, lawe mai i nā pono waiwai maika?i i nā mea hana a me nā mea ho?olaha, akā lawe pū kekahi i kahi mana?o palekana i nā mea kū?ai.

1.Natural antioxidants

?A?ole hiki ke ho?ohana ?ia nā antioxidants kūlohelohe, a ?oi aku ka nui o ka nānā ?ana iā lākou. Ho?ohana ma?amau ?ia ka Tocopherol, ka resin guaius a me ka tii polyphenols i loko o nā pastries.

No ka la?ana, tii polyphenols, i ?ike ?ia he antioxidant, vitamina polyphenols, antihalin, ?ele?ele ?ele?ele a ?ele?ele aqueous solution me ka ?ono kī li?ili?i, pauka pa?a a i ?ole aniani, astringent, ma?alahi hiki ke ho?ohehe?e ?ia i ka wai, hiki ke ho?ohehe?e ?ia i ka ?aila, maika?i ke kūpa?a wela, maika?i ke kūpa?a waika, tii polyphenols i ho?ohana ?ia i nā pastries, hiki ke ho?onui i ke kala, ho?omaika?i i nā huahana, hiki ke pale aku i ka sensory a me ka maika?i o ka mālama ?ana. ?O ka helu ho?ohui he 0.05% ~ 0.2%.

2.Synthesize antioxidants

?O ka hapa nui o nā antioxidants synthesized he pūhui phenol, a ?o ka li?ili?i o ka helu o nā hui hydroxyl ma ke apo benzene, ?oi aku ka maika?i o ka hopena antioxidant.

?O ka mea ma?amau i ho?ohana ?ia i ka pastry he butyl hydroxyanisole (BHA), dibutylhydroxytoluene (BHT), tert-butylhydroquinone (TBHQ), propyl gallate (PG), a me nā mea ?ē a?e, ma muli o nā pilikia palekana, pono e ho?omalu pono ?ia ka dosage.

3.Synergists

I ka ho?ohana ?ana i nā antioxidants phenolic, inā ho?ohui ?ia kekahi mau mea waikawa i ka manawa like, e ?oi aku ka maika?i o ka hopena antioxidant, ?oi aku ka nui o kēia mau mea acidic e hiki ke ho?oka?awale i nā ion metala e like me ke keleawe a me ka hao, i hiki ke ho?ololi ?ia kēia mau ion, a ?a?ole e ho?oikaika hou i ka oxidation o nā momona. Ho?ohana ma?amau i loko o nā pāpa?i he antioxidant corbic acid, citric acid, a me nā mea ?ē a?e, ?o ka nui o ka 1/4 i ka 1/2 o nā antioxidants.

He mea nui e ho?omaopopo he ?oko?a ka nui o nā antioxidants i ho?ohana ?ia i nā ?ano mea?ai like ?ole a me nā ?ano hana. I ka ho?ohana maoli ?ana, pono e ho?ohana ?ia e like me nā ?ōlelo ma?amau e pili ana, a ?a?ole pono e ho?onui ?ia ka dosage.
