Tenox BHT

Di-terf-butyl-4-methylphenol Eastman Tenox BHT, food grade, appeared to be very pure by GLC analysis and was used directly. The other simple alkyl derivatives of phenol were obtained from the usual fine chemical sources (Eastman Organic Chemicals, Aldrich, Columbia, and K and K). All were distilled and/or recrystallized and the assigned structures were confirmed by NMR. Other commercial stabilizers were obtained from their manufacturers, recrystallized (usually from ethanol or ethanol-water), and submitted for NMR confirmation of the assigned structure and purity.

Table 4. Effect of TENOX 4A (BHA/BHT) on stored raw and cooked beef patties (N=3)...

Antioxidant-Treated Beef Patties. The effect of several primary antioxidants, PG, TBHQ, Tenox 20 (which contains TBHQ and citric acid) and Tenox 4A (which contains BHA and BHT) were also evaluated by instrumental, chemical and sensory methods for their effectiveness in raw/stored and cooked/stored beef, see Tables 1-4. These particular antioxidants were chosen based on their antioxidant effects on MFD as determined previously (14) and because of their GRAS status. Experimental samples were prepared similarly to those of the 0-and 2-day controls, except the antioxidants, either dissolved or suspended in water, were mixed into the raw ground meat.
