CONTROL BULLETIN NO. 79 

 Acid Insoluble Ash in Linseed Meal. 



The definition for linseed meal as adopted by the Association of Feed Control 

 Officials requires that linseed meal shall contain not more than 0.5 percent of 

 acid insoluble ash. 



Acid insoluble ash determinations were made on 25 samples of linseed meal 

 collected by the feed control inspector during the season of 1934-1935. The 

 average content of all samples collected was 0.76 per cent. The maximum amount 

 found was 2.05 per cent; the minimum, 0.08 per cent. It is obvious that no 

 particular attempt is being made to limit the insoluble ash content of linseed meals. 

 It may be that the limit of 0.5 per cent as given in the definition is too high for 

 linseed meal derived from certain sources.
