s 39 os 39 content of lt 30 in the blend application_number US 98085792 A description n 30 stab values are conveniently measured after rapidly cooling the fat from 80 u00b0 c to 0 u00b0 c keeping it at 0 u00b0 c for 1 5 hrs 40 hrs at 25 u00b0 c 1 5 hrs at 0 u00b0 c 1 hr at 20 u00b0 c 1 hr at 25 u00b0 c and 1 hr at 30 u00b0 c n 30 unstab were measured after the following regime cooling from 80 u00b0 c to 0 u00b0 c 1 5 hrs at 0 u00b0 c 1 hr at 20 u00b0 c 1 hr at 25 u00b0 c and 1 hr at 30 u00b0 c although according to above the n 30 ratio applies for fat a it is very convenient when also the blend of fats a and b meets this same requirement preferred ranges for the s 39 os 39 content are less than 20 wt in particular 5 15 wt and for the ssu content more than 60 wt in particular 65 75 wt in this way compositions are obtained wherein fats a and b are completely compatible for this purpose it is preferred that the ratio between the n values at 30 u00b0 c is less than 2 fat a is advantageously a fat containing at least 60 wt in particular at least 75 wt of ssu very convenient is a fat a wherein more than 60 wt of ppo p palmitic is present very good results were obtained by applying a fat a with a.
