Technological and sensorial role of yeast β -glucan in meat batter reformulations

Abstract

This study shows that apart from acting as nutritional value improver, yeast β-glucan can be successfully used to reformulate meat products. When added to meat batters, yeast derived ingredients containing β-glucans (GOLDCELL^® IY B and GOLDCELL^® BETA GLUCAN) improved the emulsifying capacity (up to 5 increments), the water holding capacity (up to 8 increments) as well as the emulsion stability. A decrease in total fluid release up to 4.30% and 3.99%, respectively with GOLDCELL^® IY B and GOLDCELL^® BETA GLUCAN respectively, at 1.5% addition level was observed. A significant decrease in hardness and fracturability values was also observed, while maintaining the structural cohesiveness of the samples, in part due to the increase in humidity content. A maximum level of 3% ingredient mixture can be added to meat batter formulations without significant impact on sensory characteristics. Adding yeast β-glucan to meat batters can allow food to decrease the NaCl and polyphosphate content in meat products.
