- and
- a mechanically strong polymer selected from the group consisting of modified cellulose (carboxymethyl-, methyl-, hydroxypropyl-, hydroxypropylmethyl-), (pre-)gelatinized high amylose starch, agar, alginates, kappa-carrageenan, furcellaran, gum karaya, gum tragacanth, locust bean gum, chitosan and mixtures thereof.
A combination comprising:
- a pouch composed of:
- a soluble polymer, selected from the group consisting of microcrystalline cellulose, (pre-)gelatinized starch, modified starch, dextrin, maltodextrin, pectin, iota-carrageenan, lambda-carrageenan, gum arabic, gum acacia, gum ghatti, guar gum, xanthan gum, gellan gum, pullulan and combinations thereof;
- and
- a mechanically strong polymer selected from the group consisting of modified cellulose (carboxymethyl-, methyl-, hydroxypropyl-, hydroxypropylmethyl-), (pre-)gelatinized high amylose starch, agar, alginates, kappa-carrageenan, furcellaran, gum karaya, gum tragacanth, locust bean gum, chitosan and mixtures thereof;
