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.sub.3, K.sub.2 CO.sub.3,
NaHCO.sub.3, Na.sub.2 CO.sub.3, or (NH.sub.4).sub.2 CO.sub.3 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.
