Microscopical techniques are useful to characterize the structure of comminuted meat products. Light microscopy achieved the observation of fat globules’ distribution and protein gel in emulsion-type buffalo meat sausages. It revealed that caseinate and modified whey from distinct dairy protein gel regions within meat batters, and this could explain their ability to enhance the textural properties of the meat batters compared with the other dairy proteins. In minced ostrich meat batter , confocal microscopy suggested that the size of the fat droplets varied with gum type. In chicken meat gels, it showed that low-fat protein gels obtained by pressure and containing microbial transglutaminase had a more compact and homogeneous microstructure compared with controls that were pressurized but contained no MTGase. Scanning electron microscopy was useful to show structure differences in low-fat sausages.
