 Method for producing a granular sorbic acid - Patent 4133857
As for the form of sorbic acid to be employed, since sorbic acid is hardly soluble in water, it is used in such a manner that its powder is blended or kneaded with oily or solid foods.
Further, powder of sorbic acid containing a large amount of extremely fine powder as small as 300 mesh pass may be also employed without any difficulty, although the main range of particle size distribution of powder of sorbic acid used in the present invention is 70 mesh pass to 300 mesh on.
The sorbic acid to be employed in the method of the present invention, prepared in advance so as to make the powder of 100 mesh pass and 300 mesh on occupy the greater part of the particle size distribution, is obtained by separating coarse powder by means of ASTM No. 100 sieve.
