title: Effect of temperature of comminution on the stability and eating quality of 'English' sausages.
abstract: Sausages were prepared after equilibrating the ingredients to temperatures in the range 2° to 37°C. Following comminution for 6·5 min the temperatures of the batters ranged from 15 to 33°C and their pHs from 6·25 to 6·48. During storage at -20°C sausages prepared from the high temperature batters lost more weight than those made from batters prepared at the lower temperatures (0·3% compared to 1·2%). Increasing temperature of comminution led to increased cooking losses, softening in texture and darkening in colour. However, even at the highest temperatures complete emulsion breakdown did not occur as cooling losses were still only about 20%. Subjective assessment indicated that at least up to comminution temperatures of 25°C the sausages were acceptable. At temperatures above 30°C off-flavours developed. It is suggested that comminuted meat products can be manufactured in situations where refrigeration is not available, provided a preservation system can be devised to inhibit microbial and chemical spoilage.
