Rosemary oleoresin (20 ppm) was used as an antioxidant in turkey breakfast sausages prepared with 75% hand deboned turkey meat and 25% mechanically deboned turkey meat. It was compared to similarly formulated products with butylated hydroxyanisole/butylated hydroxytoluene (BHAIBHT, 200 ppm) and a control with no antioxidants. 2-Thiobarbituric acid-reactive substances in samples stored at 4°C demonstrated that rosemary oleoresin was comparable to a commercial blend of BHA/BHT/citric acid in suppressing lipid autoxidation. Sensory analysis was in agreement with these results. Analysis of volatile aroma compounds revealed the occurrence of oxidatively derived carbonyls in the sausages without antioxidants, while the antioxidanttreated sausages were essentially free from these carbonyls.

Turkey frankfurters containing 20 and 40% salt (NaCI) reductions were manufactured and evaluated in comparison to a standard formulation containing 2.5% sodium chloride. Additionally, either 0.4% sodium tripolyphosphate (TPP), sodium hexametaphosphate (HMP), or sodium acid pyrophosphate (SAPP) were incorporated into frankfurters containing similar salt reductions. Phosphates improved emulsion stability and yields, especially in formulas with 40% salt reductions. TPP increased frankfurter firmness compared to that provided by SAPP or HMP regardless of salt level. but TPP had a deleterious effect on freshness atthe 2.0% salt level.'SAPP was more effective than HMP in improving plumpness and enhancing salt flavor intensity. Overall, SAPP appeared to provide greater benefits than either HMP or TPP as a single polyphosphate for reduced salt turkey frankfurters.

Oven-roasted turkey breasts were manufactured with 70% added brine to increase yield. The brine contained salt, phosphate, and various combinations of K-carrageenan, starch, and nonfat dry milk and was incorporated into the breasts by injecting and vacuum tumbling. After stuffing into casings, the breasts were cooked at 72"C, and then cooled to 4°C. Incorporation of 0.5% k-carrageenan increased yield, improved visual appearance, sliceability, and rigidity and decreased expressible juice compared with the control product. Addition of 1% starch increased yield, but did not increase rigidity. The brine-added products were rated acceptable by a sensory panel.
