Producción de una base proteica para consumo animal a partir de residuos sólidos de carnaza provenientes de la industria de curtiembre en la ciudad de Ambato

Abstract

A good waste management in the industrial field reduces environmental impact. At present, solid waste from tanneries generates a great deal of contamination; the raw material has a high content of protein, fat and essential nutrients for animal feed, which can be transformed if a good use is sought. The objective of this work is to produce a protein base for animal consumption from solid residues generated in the fleshing stage, coming from a tannery industry in the city of Ambato. The largest amount of pork rinds was obtained in a cooking time of 60 minutes with a particle size of 6 centimeters and the drying of pork rinds at a temperature of 90 degrees Celsius for 462 minutes. The protein base composition was analyzed by physicochemical and microbiological analysis, presenting 8 percent moisture, 0.86 percent ash, 66.52 percent protein, 37.64 percent fat, 6.30 in pH, 18.59 milligrams of potassium hydroxide per gram in saponification index, 0.38 milliequivalents of active oxygen per kilogram in peroxide index, 87.3 milligrams per gram of calcium and 0.47 percent in phosphorus. In addition, it is free of Salmonella and Enterobacteriaceae, which indicates that the protein base meets the requirements established by the Ecuadorian technical standard INEN 1829:2014 and can be established as the basis of a product in animal feed.
