Chitosan in the Removal of Tailwater from the Fishing Industry to Obtain Food Incipient

Abstract

Research shows how it is possible to remove suspended solids in tailwater in the fishmeal production process in the fishing industry to obtain a developing incipient food. To achieve this incipient food, experiments were carried out with the chitosan biopolymer to remove suspended solids (SS). The methodologies used were: deacetylation, sedimentation, proof of decanters, of Weende, and, of Romero. The conclusions, regarding the tailwater of the fishmeal industry, were: 1) the chitosan biopolymer removes SS with pH = 6.5%, at a minimum of 34,2 %, after a determined time; 2) 600 ml is the dose of chitosan biopolymer, which acts as a coagulant reagent in the process of removing suspended solids; 3) the proximal composition decreases due to the effect of the chitosan biopolymer with a dose of 600 ml of the solution;  4) the developing food obtained after the process of removal of SS, is accepted in the diet by a group of cats.
