    concn. (34 and 38%), but those values cannot be obtained throughout an entire production season. Studies in 1976-1979 (on 1184, 585, 826 and 473 skim milk samples, resp., from 11, 12, 12 and 9 manufacturing plants) showed a regular seasonal variation in protein concn. of dried skim milk manufactured in Ireland; concn. were max. in Nov. (40.34-42.01%) and min. in March (32.24-34.62%), and were also affected by nutritional quality of winter feed and by climatic conditions. Requirements for heat classified and heat stable powders have become more exacting, and because of the variations in total protein (including whey protein) throughout the year, it is more realistic to classify the heat treatment of dried skim milk according to the whey protein ratio [see McGann et al., DSA 37, 5880] than by the residual amount of undenatured whey protein.
