    Notes: The contribution of some compounds previously identified in the flavor volatiles from cooked beef was estimated by surface response methodology. In most cases, predicted maximum scores for mixtures were higher than scores predicted for single compounds tested alone. Synergistic and/or synosmic effects were often indicated since mixtures frequently gave much higher scores. Predicted scores for four out of eight compounds tested were not significantly different from actual mean scores. This indicated the usefulness of the method for predicting optimal combinations of meat flavor components. The best three-component mixture consisted of 2,5-dimethylpyrazine, furfural, and 1-butanol, which gave a score of 7.54, moderately resembling meat aroma.

    Notes: Three different methods for determining nonheme iron content of meat extracts which differed in final pH and either in heating or not heating of the samples, were compared. The final pH of meat extracts had little effect on the level of nonheme iron but heating gave higher values. Both final temperature and rate of heating influenced release of nonheme iron from meat pigment extracts, with the optimum temperature being 63-70°C. Slow heating resulted in release of more noneheme iron than fast heating. Nitrite was shown to prevent release of heme iron, apparently through stabilizing the porphyrin ring. Sources of nonheme iron and their relationship to oxidation in cooked meat are discussed.
