Alaabada la dubay, macmacaanka iyo buskudka oo badan ayaa ka kooban saliid badan. Qaar ka mid ah alaabooyinkan ayaa leh qoyaan aad u hooseeya, gabowga ayaa saameyn yar ku leh noloshooda kaydinta, iyo rancidity ee saliidda ayaa ah qodobka ugu muhiimsan ee saameeya xasilloonida kaydinta.

Marka lagu daro sifooyinka saliidda lafteeda, rancidity saliiddu waxay si toos ah ula xiriirtaa heerkulka, qoyaanka, hawada, iftiinka, enzymes iyo ion birta sida naxaasta iyo birta ee xaaladaha kaydinta.

Si loo kordhiyo xasiloonida kaydinta badeecadaha, qaar ka mid ah antioxidants ayaa inta badan lagu daraa saliidda ama cuntooyinka ay ku jiraan saliid badan si ay u daahiyaan ama uga hortagaan wasakhnimada saliidda, taas oo aan kordhin karin oo keliya muddada kaydinta iyo cimriga cuntada, faa'iidooyin dhaqaale oo wanaagsan u keenaya soo saarayaasha iyo kuwa qaybiya, laakiin sidoo kale waxay keenaysaa dareen wanaagsan oo ammaan ah macaamiisha.

1. Antioxidants dabiiciga ah

Antioxidants dabiiciga ah way ka yar yihiin sunta oo ammaan ah in la isticmaalo, oo aad iyo aad u badan ayaa la siiyaa iyaga. Tocopherol, guaius resin iyo polyphenols shaaha ayaa inta badan loo isticmaalaa keega.

Tusaale ahaan, polyphenols shaaha, oo sidoo kale loo yaqaan antioxidant, vitamin polyphenols, antihalin, huruud cirro leh xal aqueous brown leh dhadhan shaaha yar, budada adag ama crystal, astringent, si fudud u milmay biyaha, wax yar ku milmay saliid, caabbinta kulaylka wanaagsan, caabbinta acid wanaagsan, polyphenols shaaha loo isticmaalo in macmacaan, qoto dheerayn karaa midabka, hagaajinaysaa guryaha dareenka iyo tayada preoxidation. Qadarka dheeriga ah waa 0.05% ~ 0.2%.

2.Synthesize antioxidants

Inta badan antioxidants-ka-sameeyay waa xeryahooda phenol, iyo tirada yar ee tirada kooxaha hydroxyl ee giraanta benzene, ayaa si fiican u saameeya saameynta antioxidant.

Caadi ahaan loo isticmaalo keega waa butyl hydroxyanisole (BHA), dibutylhydroxytoluene (BHT), tert-butylhydroquinone (TBHQ), propyl gallate (PG), iwm, dhibaatooyinka badbaadada awgeed, qiyaasta waa in si adag loo xakameeyo.

3.Synergists

Marka la isticmaalayo antioksidanter phenolic, haddii qaar ka mid ah walxaha acidic lagu daro isku mar, saamaynta antioksidanter noqon doonaa si fiican, inta badan sababtoo ah walxahan acidic ah waxay keeni karaan chelate ion biraha sida naxaasta iyo birta, si ay kuwani waxay u noqon kartaa passivated, oo aan mar dambe kor u oksaydhka ee dufanka. Inta badan loo isticmaalo keega waa antioxidant corbic acid, citric acid, iwm, qadarku guud ahaan waa 1/4 ilaa 1/2 ee antioxidants.

Waxaa muhiim ah in la ogaado in qadarka antioxidants ee loo isticmaalo noocyada kala duwan ee cuntada iyo hababka wax soo saarka ay sidoo kale kala duwan yihiin. Isticmaalka dhabta ah, waa in loo isticmaalo si adag oo waafaqsan shuruudaha caadiga ah ee u dhigma, iyo qiyaasta waa in aan si indho la'aan ah loo kordhin.
