Abstract
This invention relates to flat stock fibrous cellulosic food casings containing a low plasticizer level of between about 10 wt. % and about 17 wt. %, including at least about 9 wt. % polyol, both based upon the bone dry weight of cellulose in the casing, together with a method of making the casing.
Claims32
A flat stock cellulosic fibrous food casing containing at least one plasticizer, in a total amount of between about 10 wt.% and about 17 wt.%, including at least about 9 wt.% polyol, both based upon the weight of bone dry cellulose in the casing.
A cut flat stock cellulosic fibrous food casing containing as the total plasticizer, about 10 wt.% glycerine and about 3 wt.% propylene glycol, and between about 14 wt.% and about 17 wt.% water, all based on the weight of bone dry cellulose in the casing.
A method of manufacturing a flat stock cellulosic fibrous food casing which comprises the step of adding at least one plasticizer to the casing, in an amount sufficient to provide a total plasticizer content in the casing of between about 10 wt.% and about 17 wt.%, including at least 9 wt.% polyol, both based upon the weight of bone dry cellulose in the casing.
