ABSTRACT:
Sterilized cellulosic material which resists discoloration when exposed to undue post-sterilization heating (e.g., 100.degree. F. to 150.degree. F.) is provided by stabilizing the water content by weight of the pre-sterilized cellulosic material to not less than 6.5% by weight--preferably, at least about 8% by weight--with the water content being maintained at less than about 12% by weight, preferably less than about 10%, so that the cellulosic material remains dry to the touch.
