Abstract
The effect of addition of kappa carrageenan, guar gum and xanthan gum (in different proportion and combinations) on quality of low-fat comminuted scalded sausages (7% of yowl in the formulation) was evaluated. The influence of these additives on pH, contents of water, fat and protein, colour values (a*, b*, L*) and texture parameters was investigated. It was proved that replacement of 0.5% carrageenan by 0.4% guar or xanthan gum was not advantageous. This caused worsening of texture parameters, sensory scores and greater drip loss during storage of vacuum packed frankfurters. Greater drip loss was also observed during 3 weeks storage of frankfurters with addition of only carrageenan. Common addition of carrageenan and guar or xanthan gum retarded syneresis. Therefore it could be recommended. The best quality product (with good technological properties and high sensory quality) was obtained with the simultaneous addition of 0.2% of xanthan or guar gum and 0.25% of kappa carrageenan.
