Abstract:
Emulsion stability (ES) was measured on timed emulsification (TE) samples made with natural actomyosin (NAM) and exhaustively washed (EW) muscle, heated to 75°C, before using the Omni-mixer or after centrifugation. All emulsions cooked after centrifugation were found to be stable. The emulsions made with NAM showed a large decrease in ES when heated above 40°C prior to using the Omni-mixer. However, aqueous protein disappearance did not decrease significantly after TE until NAM was heated to between 60°C and 75°C. On the other hand, emulsions made with EW muscle heated prior to using the Omni-mixer showed a large decrease in both ES and aqueous protein disappearance after TE between 60°C and 75°C.

Mosaic nature of the membrane
The mosaic characteristic of the membrane helps the plasma membrane remain fluid. The integral proteins and lipids exist as separate but loosely-attached molecules in the membrane. The membrane is a relatively...
