      BHA or BHT.

AB  - In this study, we prepared new antioxidant active plastic bottle caps by 
      incorporating butylated hydroxyanisole (BHA) or butylated hydroxytoluene (BHT) 
      and 2% (w/w) white masterbatch in high-density polyethylene (HDPE). 
      Fourier-transform infrared (FT-IR) spectrometry revealed that the antioxidants 
      and HDPE were uniformly mixed with noncovalent bonding. In addition, the 
      differential scanning calorimetry (DSC) test revealed that the change in melting 
      point and initial extrapolation temperature of the antioxidant active caps was 
      not significant. Sensory evaluation and removal torque tests validated the 
      suitability of the antioxidant active plastic bottle caps in industrial 
      application. The antioxidant activity increased with a greater concentration of 
      BHA and BHT incorporated in both antioxidant active caps (p < 0.05) and with more 
      impact on the BHA cap compared to BHT cap in terms of antioxidant activity. 
      Migration experiments for 10 days at 40  degrees C and 2 h at 70  degrees C showed that active 
      antioxidants in the plastic bottle cap were more easily released into fatty foods 
      and milk products that are highly sensitive to oxidation, and the migration of 
      BHA and BHT did not exceed the maximum amount specified in (EC) No 1333/2008 
      (<200 mg/kg). As such, the antioxidant active plastic bottle caps inhibited 
      oxidation, thereby ensuring higher food quality.
