Meat products (10 g) were weighed in a beaker.
Deionized water (150 ml) was added and blended for 2
min in a laboratory blender. The suspension was incubated
for 15 min in a warm water bath at 50 C. After
cooling, the volume was diluted to 250 ml and filtered
through a Whatman filter paper. An aliquot of this
solution was then filtered from a 0.45-mm celluloze acetate
filter disc. Three milliliters of solution were collected,
0.267 ml of internal standard stock solution
(KSCN) was added and the volume was diluted to 4 ml.
The resulting solution was injected directly
