In a food skin based on cellulose hydrate impregnated on the inner side with a liq. smoke, the liq. smoke has pH 2 to below 4, and contains also (a) a cpd. to increase the viscosity and (b) an emulsifier. Pref. the cellulose base material is free from glycerol, and contains alginic acid or alginate. The liq. smoke has pH 2.5 - 3. The component is 0.5-3 (1.5-2.5)wt.% of chitosan, a polysaccharide, a starch deriv. or a cellulose deriv.. The emulsifier is 0.5-15(1-5) wt.% of an ionic emulsifier, pref. an alkyl or alkylaryl sulph(on)ate, or a nonionic emulsifier, pref. an ethoxylated 6-20C alkanol. The liq. smoke also contains 2-30% (5-15%) of a natural or synthetic triglyceride, esp. olive oil, sunflower oil, a synthetic triester from glycerol and an 8-10C fatty acid, or lecithin. A cellulose hydrate tube contg. 8-12 wt.% of water is moistened on the inner side with water, impregnated with the liq. smoke, and finally dried to 25-35% water content. |
