Food coating substance, production and use thereof

摘要

A coating composition for foodstuffs comprises an aqueous copolymer poly(vinyl)ester dispersion comprising 100 pts. wt. of a copolymer of 40-95 wt.% vinyl esters of aliphatic saturated carboxylic acids and 5-60 wt.% maleic acid esters and/or fumaric acid esters of monovalent aliphatic 1-18C alcohols and optionally other comonomers and 0.1-1.0 pts. wt. of an emulsifier. A coating composition (I) for foodstuffs comprises an aqueous copolymer poly(vinyl)ester dispersion comprising: (a) 100 pts. wt. of a copolymer of 40-95 wt.% vinyl esters of aliphatic saturated carboxylic acids and 5-60 wt.% maleic acid esters and/or fumaric acid esters of monovalent aliphatic 1-18C alcohols and optionally other comonomers; (b) 0.1-1.0 pts.wt. of an emulsifier; (c) 0-0.45 pts.wt. of a cellulose ether and; (d) optionally other stabilizers. An independent claim is included for a process for the production of the dispersion by radical emulsion polymerization of the monomers in a batch and/or continuous process whereby 1-15 wt.% of the monomers (with respect to the total quantity of monomers) is added to initiate polymerization.
