The experimental design method was applied to the study of influential factors on sample preparation for staphylococcal enterotoxin detection in cheese products. Statistical evaluation has shown only one significant factor of food extract composition - concentration by dialysis -. The levels of other factors were chosen in order to have an easy-to-use and optimal preparation procedure before detection.

Key words: Experimental designs / extraction procedure / concentration by dialysis / staphylococcal enterotoxins / cheese product.
