The present invention relates to gelled feed products, means for making said products and a method for manufacturing gelled feed products. The product comprises 80-98 weight % raw material of animal or marine origin pre-treated with KOH and/or NaOH, KHCO , K CO , NaHCO , Na CO , or (NH ) CO and 0.5-5 weight % alginate or pectin, a calcium source standard feed ingredients and calcium. The product may contain 0-10 weight % fish meal or carbohydrates. Said means are raw material of animal or marine origin pre-treated with alkali giving said raw material a pH of 8-12. The method comprises mixing raw materials of marine or animal origin, comprising offals, alginate or pectin, and a calcium source and standard feed ingredients, particulating said mixture into any useful geometrical shape, expose it to acid treatment in a bath. The raw material is pre-treated with alkali or to addition of alginate or pectin. The resulting mixture is formed into desired shape and treated in an acid bath to form the gelled product. Preferably the acid bath is having a pH of 0.5-5.5 and the retention time in the bath is 30 seconds-12 hours. The preferred acid is formic aid.

Gelled feed products, means for making the products and method for manufacture of said products

The use of G-block polysaccharides as a modulator for the rheology in a mixture in which a gelling, water-soluble polysaccharide is a component to give the final product a changed viscosity, stability, elasticity, rigidity or similar.
