摘要：
Various analytical methods for sorbic acid determination based on removal of the preservative by distillation or ether extraction, followed by UV or colorimetric analysis gave relatively poor recoveries (52 - 84%) when applied to raw beef. An improved procedure was developed based on disintegration and dispersion of beef with sand prior to steam distillation and colorimetric determination. This resulted in almost 100% recovery of sorbate, attributed to more efficient extraction because of increased surface area.
