A fundamental study for the preparation of fatless fish meal was carried out on regard to the extractant which can extract water and crude fat simultaneously from wet scraps of fish at room temperature. Necessary amount of an extractant was found to depend on both the composition of a fish oil -extractant- water system and the quantity of an extractant retained in the scraps during the extraction. A trial preparation of the meal was made in a rotating ball mill pot provided with the wet scraps and extractant inside. The fish meal obtained was light colored, absent from unpleasant smell and finely powdered. It was found the mixture of acetone 4 and benzene 1 by weight is a suitable extractant and about 420g. is necessary for treating 100g. of the wet scraps. Crashing of the scraps in the extractant by the ball mill is not so complete (especially in a case of bones) that more powerful crashing is desirable.
