The glyceride mixture should not contain more than 10% by weight of triglyceride and the coating composition may also include a palmitic, oleic or stearic acid ester of sorbitan or manitan. The cellulose ether may be carboxymethyl cellulose, methyl cellulose, hydroxypropylcellulose, hydroxyethylcellulose, ethyl- or carboxymethylhydroxyethylcellulose, or hydroxypropyl methyl cellulose. Application of the coating composition may be regulated to simultaneously humidify the casing and bring its moisture content to about 18 Œ 1% by weight. Coating may be effected by introducing a quantity of the aqueous composition into the casing or by spraying. |
