abstract
Whole hog sausage patties made with (1) no phosphate, (2) 0.375% sodium tripolyphosphate (STP) and (3) 0.441% LemOFos in combination with salt levels of 1.5, 1.0, 0.5, and 0.0% NaCl were frozen and packaged. Use of phosphates decreased offflavor and rancidity development, improved binding, and increased pH values, cooking yields and scores for saltiness and juiciness. The prooxidant effect of NaCl was masked by the antioxidant properties of STP and LemOFos. Extended periods of frozen storage reduced cooking yields, juiciness and texture scores and enhanced development of offflavor and rancidity. However, use of phosphates or vacuum packaging exhibited an antioxidant effect during extended periods of frozen storage. Copyright 1984, Wiley Blackwell. All rights reserved
