antioxidant activity of bha, bht and tbhq examined by brazil
Antioxidant activity of BHA, BHT and TBHQ examined
antioxidant index for TBHQ was 3-fold higher than for BHA and BHT. Higher antioxidative activity of TBHQ compared with BHA and BHT in model studies with soybean oil and chicken fat in emulsion versus dry oil tests was reported by Cort et al. (6).

The influence of BHA, BHT and TBHQ on the oxidation
Influence of BHA, BHT, and TBHQ on the oxidation stability of ethyl esters from soybean oil Synthetic chemicals such as BHA, BHT, and TBHQ are primary antioxidants that interrupt the free-radical chain of oxidative reactions by contributing hydrogen from the phenolic hydroxyl groups, themselves forming stable free radicals which do not initiate or propagate further oxidation of lipids.

Antioxidant activity of BHA, BHT and TBHQ examined
Antioxidant activity of BHA, BHT and TBHQ examined with Miller's test In model experiments with the use of Miller's test to 5 ml emulsion 25, 12.5, 6.25 and 3.13µg BHA, BHT and TBHQ was added. Inhibitory ratios (IR) for BHA and BHT were similar.

Application and stability of natural antioxidants
The antioxidant activity of extract was compared with BHA, BHT and TBHQ at 200 ppm and α-tocopherol at 500 ppm. Green tea extracts at higher concentrations than 200 ppm showed excellent antioxidant activity in both oils and its efficacy was higher than that of BHA, BHT and α-tocopherol, but less than that of TBHQ.

Commercial antioxidants and thermal stability evaluations
BHA, BHT, TBHQ and PG are the synthetic antioxidants that are most commonly used in industry [8], [9]. Among the most widely used natural antioxidants are the tocopherols and phenolic acids [10], [11]. Citric acid and ethylenediaminetetraacetic acid (EDTA) salts are the main chelating agents used [8], [12].

Antioxidants: Regulatory Status
BHA (Butylated Hydroxyanisole) and BHT (Butylated Hydroxytoluene) Phenolic and polyphenolic compounds are the most active dietary antioxidants (14). The structural variation of phenolic antioxidants directly influences their physical properties, resulting in differences in their antioxidant activity.
