The determination of isolated soybean protein in raw and pasteurized meat products

Abstract
Summary: Sodium dodecyl sulfate‐polyacrylamide gel electrophoresis was used to determine the isolated soy protein content in raw and pasteurized meat products. This method determined soy protein (±0.5%) by using an internal standard protein (haemocyanin) to compensate for variations in the meat. The detection limit for meat products was 0.5%. Several possible meat and non‐meat interferences were examined and none were found to interfere. The assay cannot be used on retorted products.
