The Effects of Different Levels of Non-Fat Dry Milk and Whey Powder on Emulsion Capacity and Stability of Beef, Turkey and Chicken Meats
(Blackwell Publishing Ltd, 2005) Kurt, S; Zorba, O
The effects of different concentrations (0.00, 0.25, 0.50%) of either non-fat dry milk (NFDM) or whey powder (WP) on emulsion capacity (EC) and emulsion stability (ES) of beef, chicken and turkey meats were studied by using a computer model system. The effects of meats types and additives (NFDM and WP) on EC and ES were found to be statistically significant (P < 0.01). Of the meats, chicken had the highest and beef the lowest values of EC and ES. When using different concentrations of WP and NFDM, 0.25% WP and 0.50% NFDM had the highest values of EC. The effect of different concentrations (0.25 and 0.50%) of WP was insignificant on ES; however, the effects of different concentrations (0.0, 0.25 and 0.50%) of NFDM were significant on ES.
Stability of Model Emulsions Prepared Using Whey and Muscle Proteins
(Wiley-v C H verlag Gmbh, 1998) Zorba, O; Ozdemir, S; Gokalp, HY
The amount of water (SW) and oil (SO) separated from model emulsions and emulsion stability (ES) of these emulsions prepared from corn oil and of fluid whey, total muscle protein (TMP), whey + TMP and sarcoplasmic protein (SP) were examined. The SW value of whey + TMP emulsions was lower (26,33%) than that of TMP (31,33%), SP (39,0%) practically the same as that of whey only. However, the SO value of whey emulsions was higher (9,40%) than that of muscle protein emulsions (0,0%). It was found that there was no oil separation in whey + TMP emulsions. Whey proteins had the lowest ES (64,6 +/- 0,96) among the proteins studied. Nevertheless, whey + TMP emulsions had the highest ES (73,67 +/- 0,58).
