title: Quality assessment of pasteurized fluid milk as related to lipopolysaccharide content.
abstract: A study was conducted to investigate any relationship between lipopolysaccharide (endotoxin) concentration in milk and parameters associated with the keeping quality of milk. Parameters investigated were flavor intensity, standard plate count, coliform count, psychrotrophic count, and gram-negative count. Lipopolysaccharide content was determined using the Limulus Amoebocyte Lysate assay. Pasteurized whole milk samples were obtained the day of processing in .94-L containers with samples analyzed on d 0 through 21. Significant linear relationships were detected between lipopolysaccharide concentration and days storage at 7 degrees C, flavor intensity, and psychrotrophic count.
