摘要:
The invention relates to a process for the preparation of water-soluble chitosan salts, to chitosan products produced by this process and to their uses, e.g. in pharmaceutical or veterinary compositions or as a food or cosmetic additive. More specifically, the invention relates to a process for preparing a water-soluble chitosan salt which comprises: (a) contacting a solid chitosan with at least one protic acid whereby to produce a water-soluble chitosan salt; and (b) optionally recovering said salt, wherein said chitosan is converted into said salt whilst remaining substantially in the solid state. Gaseous or liquid protic acids may be used, including hydrochloric, acetic and propionic acids.

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, KHCO3, K2CO3, NaHCO3, Na2CO3, or (NH4)2CO3 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.
