Peroxidation studies indicated that phospholipids, microsomes and mitochondria from cured pork samples are less susceptible to metmyoglobin/hydrogen peroxide-catalyzed peroxidation than their counterparts from nitrite-free pork samples. The reaction

This study investigated the effects of the phenolic antioxidants (BHA, BHT and PG) on the mutagenicity of IQ, MeIQ and MeIQx by the Ames test. Results demonstrated that MeIQ, IQ and MeIQx were all mutagenic when tested with the Ames test with their p

Five groups of spent layer hens (about 17-month-old White Leghorn, commercial strain) with 10 birds in each were fed a commercial-type broiler ration supplemented with DL-α-tocopheryl acetate (ATA) at a level of 0, 500, 750, 1000 or 2000mg/kg of fee

The reaction of metmyoglobin (MetMb) with hydrogen peroxide (H 2 O 2 ) generated a free radical that was detectable by ESR at room temperature only in the presence of the spin trap 5,5-dimethyl-1-pyrroline-N-oxyl (DMPO). The formation of the free rad

The effect of salt and pH on the colour stability (oxymyoglobin) in the sarcoplasmic extract (SPE) prepared from pre- and post-rigor beef muscle was studied in the presence or absence of mitochondria and microsomes during 96 h at 4°C. The sarcoplasm

The Maillard reaction, which involves Amadori rearrangement as a key step, also results in sugar fragmentation and free radical formation. The imidazoquinoline meat mutagens (2-amino-3-methylimidazo[4,5- f ]-quinoline, or IQ, and 2-amino-3,4-dimethyl

Two experiments were carried out to ascertain if supplementation of a semipurified diet to Swiss-ICR mice with either ascorbic acid (AA), vitamin E (Vit E) or a combination of the two would modulate the carcinogenic effects of N-nitrosopyrrolidine (N

Numerous procedures for improving the entry of aggregates and of large myosin subunits into disc gels were investigated. Both rabbit and bovine myosin behaved essentially the same during electrophoresis in urea. Aggregates of myosin and large and sma
